Do you know your tire's treadwear rating?

[Koenigsegg]

I'm reading about it now, and I have no idea. . .

 

[AccruedExpenditure]

neither do I

 

[ondarkness]

z

 

[tvbi]

240

 

[Kalvin00]

No..

 

[Toasthead]

isnt it a number like 400 or something?

I was always told if you take the first two digits and double it thats how many thousand miles it should be good for

80k in my example

 

[acemcmac]

Yeah

Treadwear rating: "changemallthefvckingtime"

I drive like a madman on my yokohoma ultrasummersportsemislicks Z-type :beer:

Z is not a treadwear rating it's a speed rating. Treadwear is a number.

And yes 440 for both vehicles

Sorry no... it's a comparitive number. A 200 SHOULD last twice as long as a 100 but only within a specific manufacturer. Because the way the test is run, there can be differences between makers. So one company's 200 rated tire may only be a 150 from another. So if you want to compare ratings across companies, look to the warranty as well. For example, MY Eagle GT-HR's are 440's with a 50K mile warranty - so 50000/4.4 (to find per 100 baseline) is 11363. But a set of Pirelli's I looked at for the Xterra had a 65K warranty with a 500 TW rating or 12500 per 100.

(editing for clarity)

Yes, no set of tires will last for 80k unless you're driving on ice...

 

[NutBucket]

190

and no, they don't grip nearly as well as they should given the treadwear rating.

 

[Anubis]

not a clue

and i dont even now what that means

 

[Bullhonkie]

140 IIRC

 

[BillGates]

mine should be somewhere right around 7 - too bad that isn't a real choice

 

[mwmorph]

150 for MR2
300 for Camry(father's)
400 for MPV Van(mother's)

Wrong, I've gotten 80K out of tires before. Potenzas they were.

But sure, I know my tire's treadwear rating.

 

[Demon-Xanth]

Nope, I can't read the numbers.

So did I... And of stock BFG's Long Trail TA's. There's no mileage warranty on those at all... Gotten 50K on the 2nd set, and still close to 1/2 the tread depth there. A lot of it has to do with how and what you drive. Though in the Xterra's case, with it being a 4x4 that didn't help. But I do take care of it, including watching the tire pressure. The Xterras have a known problem with pulling to 1 side if the tire pressures are even slightly off.
