The "55" in 205/55R16 means that the height of the sidewall of the tire is 55% of the width of the tread.
caesarjd
Here in the UK all they sell are Summer or Winter tires...in a country that never gets hot, and never really gets cold either...
Loquatsandwildhoney
Width and aspect ratio/profile are mixed up.
RegisteredAirplaneDoctor
You know what, I'll just put aircraft tires on. They have the best dynamic loading and high speed characteristics
firstofficercheese
Pretty awful for cornering though.
cogs
The Michelin XGV 75R14 is the most popular size of the best selling single model tire in the United States today.
thedeg
Theres no thing as All season tyres. Theyre just shitty summer tyres or shitty winter tyres, depending on the season.
Blaker
Get some LT tyres if you can afford them. Has a few more plys in the sidewalls and tread, helps for potholes and gravel and such.
theboringusername
So where do I find how much psi to keep em at? Just got a Ltp warning...
Zordicron
That will be the vehicle's recommended PSI. Should list in owner manual, or sticker on door jam.
theboringusername
Was right there. Thanks for responding, friend.
LilSaint001
recommended is always at driver door jam for most vehicles. Even if you put 32psi on P tires doesn’t mean its correct psi for LT tire.
theboringusername
Got it. Fixed. Thank you for the quick response!
STGxDante
Also AWD owners, make sure your front & rear tires have the same radial diameter or within 1%. Or you can mess up your diff./ Transfer case.
disgruntledtruckdriver
AWD vehicles have a center differential so as long as they are the same rated size, they should be good. Part time 4x4 systems that lock up
disgruntledtruckdriver
should not be used in 4x4 at all on dry or paved surfaces, as there is no center differential to compensate
kubricky
I'll do one for race tires...well done, this is a great thing for people to see. There is no "mystery" in it, just takes a little education
phoenixgrinder
and never, ever buy the cheapest tires they have for sale. learning that lesson myself now ..
herppavitunderrpa23
it's even more hilarious when the people with the most expensive cars want the cheapest tires. they're your only contact to the road man...
InsanityBuildsCharacter
lol. fuck those chinese DingLingLongDong tires. :D I've laughed myself silly when someone buys 6k rims and uses the cheapest tires possible
clutchthepearls
Cheap vs inexpensive. Continental DSW06 is half the price of a Michelin Pilot Sport A/S for being 99% as good a tire. Do research.
esgedi
Cheap tires are fine if you buy from the right company. They won't be bridgestones, but most cheaper japanese tires are good/cheap.
phoenixgrinder
brand called 'Radar' .. trash I tells you
mandrigan
You're absolutely right, working at Dunlop Tires. Never buy the cheapest tires
klayman1984
Well that's nice, but what unit is 91? 91 weight? Also what's V? V for vroom vroom?
rabidkitty4
I thought it was 5 speed.
ekyxor
V = Very fast
TheBlueMuppet
I just think its weird it has metric and imperial measurement.
seentoomuchdeath
This.
AzgarOgly
It has metric, imperial and indexed values. What a mess :)
klayman1984
Also, what about the pressure range the tire is designed to work under? What unit?
TheDrunkenWrench
The tire's max pressure is written in either psi or kpa, and it will be marked as such. The pressure you use is in the door jamb of yo car.
klayman1984
Right, but I can change the tire, but won't change the label on the door jamb. Plus fave: door jamb: kPa. Pump: bar + psi...
TheDrunkenWrench
You ignore the pressure on the tire, and use the one on the door jamb. punch your kPa rating in to google and convert to unit used at pump.
klayman1984
What if door jamb tells me to use 270kPa, but tire says max is 250kPa? I'll blow my tire... I can convert, it's more a "lol standards" thing
InsanityBuildsCharacter
91 is the weight rating (ie. how much weight it can carry) 91 = 615kg. V is speed rating, V= 240km/h
GeorgePotompkin
How does 91 covert to 615kg, what are the units on the 91?
LilSaint001
keep in mind. Its rating. theres a chart for both ratings. And the weight is spread out on 4 tires.
GeorgePotompkin
That makes sense, rating not literal scale, thanks!
InsanityBuildsCharacter
The scale is asymmetrical, like 92=630kg, 93=650, usually just rely on what the car mfcturer states in manual. NEVER EVER SMALLER RATED!
GeorgePotompkin
I see, its just a convention like ABEC on bearings.
mandrigan
I'm working for Goodyear/Dunlop if someone is interested, I could take some pictures of how a tire is made from scratch
muhvitus
Make gif post. If you are too lazy, make it from some youtube video
Zordicron
ORLY? In the USA? Can you tell me which tires are actually made in USA so I can buy an American tire for my Mustang and old Dodge Ram?
Grandshift
Don't tightarse when buying tyres, always invest in a quality set as they are the most important part of any vehicle.
albinoblacks
Completely agree. As a car enthusiast the three things I tell friends/coworkers is never to be cheap about tires, brakes, and oil.
Zordicron
I would spend money on brakes, then tires. But it is true that cheaper tires are usually a money sink in both performance, and longevity.
albinoblacks
Imo brakes and tires are similar in importance with out one in good working order the other is useless and as they both keep you alive.
SteveO
that's debatable
Grandshift
this should be fun; how exactly is the thing that literally keeps you on the road, not the most important part of a vehicle?
kelpo122
Though I agree that it is the most important part for safety reasons
kelpo122
Maybe he went to the super literal way, so maybe the thing that converts gasoline into mechanical energy is THE most important part? 1/2
hifive2wifei
Maybe show the number/date convention; some of these sit on the shelf or in warehouse long enough to be dangerous.
LilSaint001
well shelf life is something but having tires with good thread and is 15 yrs old doesn’t mean its still good.
InsanityBuildsCharacter
most commonly its just (ww/yy) stamped on the side of the tire. last 4 digits on the DOT txt
ohdued
Metzeler did a test of new vs 5 yo properly stored tyres and did not notice any difference on a sports bike. Couldn't find the sauce, sorry.
Elpepitos
They would have to sit for years and years to become 'dangerous' but you're not getting your money's worth if your tire spent more than 6mon
InsanityBuildsCharacter
on winter tyres, i think they become dangerous about in the age of 7yrs, for example a mag tested aged tires & on 10yo tire breaking
Elpepitos
th on a shelf
InsanityBuildsCharacter
distance was as much as 70 meters longer than on a new tire. All tested tires were in as new - condition (less than 5 studs fallen)
LinkinPiper
I feel like an over educated South Floridian now.
iHveNoCleverName
So to sum it up. Its not the size of the tire that matters, but the way you use it?
aalien
As a professional Finn, there is no such thing as all-season tyres.
InsanityBuildsCharacter
Turku & kitkarenkaat. Ei oo ollu tarvetta nastoille kohta vuosikymmeneen. Työkseni ajan
aalien
Soosoo. TM:n testeissä kitkat pitivät märällä asfaltilla huonommin kuin paskimmat kesärenkaat. Kitkat kuuluvat vain oikeaan talveen.
InsanityBuildsCharacter
kerran ollut ojassa ja silloinkin kun auto vaihtui automaattivaihteiseksi ja pääsi kaarteessa yllättämään ;) kesällä tietty kesärenkaat..
JohnQPubic
finally living in florida pays dividends
bingotown
All-season tires are really three-season tires. Get snow tires if you live where you get real winter. HUGE difference. Much safer.
muhvitus
And they usually suck against summer tires on wet as well. The problem being that icy, dry and wet require different things from tire.
muhvitus
You can't have it all so all season is always compromise
FastestBearAlive
Aight. Got it. So Pirelli P Zeros on my Honda Odyssey
clutchthepearls
Sure, if you want to pay a premium price for a so-so tires.
Hybris51129
Now you are prepared to find out what the top speed of a fully laden Honda Odyssey is.
FastestBearAlive
Using that naturally aspirated V6 V-Tec engine to its max
ShimmerFairy
"What's the maximum safe speed for this tire?" "V."
DavidsPlayToy
30 speed
dargon
All car tires have a speed rating in the form of a letter, V rated tires can go up to 149mph or 240km/h.
ShimmerFairy
I figured it was something like that. If only the infographic informed us.
CherylCarolCherleneTunt
Hate the sound of off road tires on pavement. How do you not hear that irritating hum when you're driving?!
Hybris51129
This is true but a lot of the newer off road tires have gotten far better in this respect.
Zordicron
Nowdays that hum is reserved for cheap, or extreme off road tires. I have Kelly Safari TSR on my Ram and they are quiet.
LilSaint001
Well ever heard or the fix by radio? “Hear weird noise, turn volume up till noise is gone” Done deal.
FrodoShrugged
I have heard that you should not fill your air pressure to the max amount shown, but go under that a bit. Can anyone confirm and/or clarify?
disgruntledtruckdriver
The preassure rating on the tire is max cold psi. So even the the tire will warm up while driving, you're okay. However you should use the
disgruntledtruckdriver
recomended inflation pressure on the door jam, not the tire.
FrodoShrugged
Did not know that, awesome - Thank you ! :)
Hybris51129
Just wanted to add that if you use a different size tire then what originally came with the vehicle then you can fall back on the (1)
Hybris51129
pressure stamped on to the tire. Just be sure to keep an eye out of unusual wear that maybe pressure related.
Skawomplious
Not just a bit, you shouldn't be anywhere near it for normal driving. Go by the PSI listed on your vehicles door sticker.
Skawomplious
If you're running a different size or style tire than OEM, you can always contact the tire manufacturer and ask them.
disgruntledtruckdriver
On my ram 2500 Door jam and tire max cold psi were both 65 psi. It does happen.
sorryicameinyourhairhoney
For anyone who drives in the snow, GET SNOW TIRES! I cannot stress this enough!
bingotown
Thank you. All season tires are really three season tires.
Hybris51129
Or at least quality all terrains that are rated for severe snow service.
bl1ndseer
Even those are bad on ice
Hybris51129
Everything short of studded tires is terrible on ice.
bl1ndseer
Thats not true, winter tires can make the difference between an accident and not. https://www.youtube.com/watch?v=ERtK8q2PxGg
GlassBomb
Something to note. Tires go bad and dry up after a few years, tread might be good, but they are dry AF and won't perform as well anymore.
thewiggins
depends on the quality of the tire, but they all go bad eventually, tread separation is no joke
GlassBomb
The week and year when the tire was made is written on the sidewall.
slack3rdav3
14/11 is what mine say... Knew they were old, and still have good tread. Def feelin wonky in the rain though, gonna replace soon.
clutchthepearls
Can't be sold at 6 years, shouldn't be used after 10 years. IIRC.
madmatt2024
Nope, at least not in the US. Also, how old a tire is isn't necessarily relative to weather its safe or not, there is much more in play.
clutchthepearls
Rechecked, not that it "can't" be sold, but most chains won't sell tires that are 6 years old. 10 years is the oldest manufacturers (1)
clutchthepearls
recommend using a tire. Obviously if a 3 year old tire has dry rot or has a ring from being run flat, it will be worse than a 7 year old (2)
clutchthepearls
that was properly maintained, but 6 and 10 years are basically the age limit you should be buying and using tires. (3)
madmatt2024
We got a memo from Michelin when I worked in a tire shop that said 10 years of storage = 1 year of use in terms of tire deterioration.
TheOtherAlan
What really trips me out is that it's just pressure and friction keeping those tires on the rim.
Eastfield
In some special cases (like with the Bugatti Veyron) glue is needed aswell :)
pallentx
its less crazy when you see the whole tire. it cant fly off the rim because the tire 180 degrees around holds it down.
ILikePugandFrenchiePictures
You will stop being tripped out the first time you have to get an inflated tire back on the bead. You'll understand why it works, intimately
DustyMcKnuckles
Mmm "I love the smell of ether in the morning"
PixelSprite64
Woonski
Watching dragster tires fold in slo mo is always cool
Cal1te
Some offroad wheels have the capacity to 'hold' a tyre, this allows you to run lower than normal pressures for better grip.
cuzitsthere
"Beadlocks" for anyone wanting to Google this
Cal1te
Thanks, couldn't for the life of me remember what they where called. :D
TearingAway
Breaking the bead to unseat a tire w/o the right tools is an arduous task...even w/o air in the tire!
MarkHughes
Indeed, I have a machine for the job but it can still be a fight to unseat an old tyre.
mandrigan
chardlz
That's why blowouts are so dangerous
StevenAlequin
Well, just imagine airplanes staying up in the air. Its a several hundred thousand lls piece of metal, glass, and flesh riding air!
psaicl
What else should?
CotterPyke
ironically, that's what keeps you and me from floating away in space
Farmergirl753
The rim is bigger than the tire,and they're convex and concave to mesh. PLUS most places put "bead seal" a rubber glue to seal them together
LatrineUsedToBeShitHouse
You'd be surprise what pressure and friction is capable of. That's why my parents got married right before my birthday.

I mean... If I put 35 pounds of pressure per square inch on top of your feet you'd likely not want to go anywhere.
RelativelyRelevantRelative
I would definitely want to go somewhere, but I probably couldn't.
TheOtherAlan
Still trippy. I at least thought there would be a lip on the inside of the rim for the bead to latch
KaputtmachTheBavarian
there is actually a thing of this kind inside the rim, it's called "hump" http://edge.tireguides.com/images/tips/wheeldimensions.jpg
HolleyRagnarok
reason off-roaders use beadlocks, as well as CTIS equipped vehicles
mandrigan
UltraDi3000
If i remember hearing correctly on old Top Gear the R35 GT-R has a lip to prevent the tires comming off, cause it can corner so hard.
Arkleseizure
And hard enough to destroy Clarkson's neck
istealthepixelsfromreposts
The bugatti veyron ones are actually glued. You have to change the rims every fourth tire change i think. Very expensive.
KaputtmachTheBavarian
they are not glued but vulcanized which means the tire was baked onto the rim. you actually have to change the whole set of wheels 1/2
KaputtmachTheBavarian
which is afaik around 20.000€ (~23.500 USD) PER WHEEL 4/4
Compound515
But I mean if you have e a Bugatti Veyron I assume changing the tires isn't a break the bank decision

AzgarOgly
That depends on a winter. If it is "four months under -20C straight" winter, go with winter tires. //
AzgarOgly
If it is "melts in the day, freezes in the night", M+S type are quite ok.
LilSaint001
I work in part dept and I F’ing hate people sayng “I only want M+S to go up the mtn in 3inchs of snow” I know 3” is nthng but its nt for it

As an Australian, summer tyres are good all year round.

This. I've driven my Impreza in the snow with all-seasons, summer tires, and winter tires. There's a reason I don't use all-seasons anymore
muhvitus
Sometimes things just happen that you cannot do anything about except react immediately and it's then when all season fails vs. real winter.
NorwegianJim
You're not even allowed to call them "all season" here in Norway. They're either for winter, or for summer. You can't have both!
weeliittleone
Same from where I am in Canada - only called "3 season" or "temperate weather tires"

Efreeti
Here in Norway we've had to practically outlaw (or put heavy fees on) the use of studded winter tires due to asphalt dust pollution.
muhvitus
You could call studless winter tires all season but they will work badly in summer compared to summer tires. The all season tires are BS.
Efreeti
Yep, we use summer tires and studless winter tires.
