How to determine when a V710 is worn out

[Arthur Grant]

Besides the tire being at the core what are the characteristics to consider when deciding to scrap a tire? I am talking truly worn out, were you would be better off runing your street tires from pep boys.

Depending on the car and alignment, of course, you'll heat-cycle them out before they cord. After about 50 runs the grip level really drops off and you'll be sawing the wheel to keep the car pointed the way you want to go.

If you pick up tire and metal starts poking you, it's definitely worn out. Otherwise, as long as you still have satisfactory driving characteristics, you can use the tire. It's hard to tell just by looking.

From my experience with the V710 on a rwd car, the forward bite starts to fall off in the 60-80 run range. They are still very usable, I have gone over 100 runs on them, but the tail of the car starts to slide around a bit.

You will never reach the point that the street tires are better, as long as the V710 is holding air it will be quicker than a street tire.

I don’t think Pep Boys sells Toyo cheater tires?
You would nearly never be better off running your street tires from Pep Boys vs a 710 unless the 710 had no air in it at all. If you keep your 710s out of the sun they will last a long time. I just ran 30 more good runs on a set of 710s that were purchases in August 2005. The 710s had 91+ runs on them before the 30 new runs. They were not 100% as if they were new but they were still way better than any of my street tires with the exception of my nearly new RE-01 Rs and still my 5 year old 710s are better IMO.

If the 710 is super hard, has colors (like oil and water) on the driving surface and all the groves are gone I would trash them however some folks would mount them up and use them.

Teasing about pep boys, my street tires have been Kumho ECSTA SPT's and are being changed over to brand new 285/40/17 Kumho ECSTA XS. But was wondering about the 710's since I have developed a small stock of used one.

The one in the middle has a few runs left.

Got money's worth on that set.

Thanks guys

DEPENDS ON YOUR DEFINITION OF WORN OUT....

when they look like this

Early in my autocrossing days, this tire would have been nothing a little shoe polish couldn't have fixed.

The one in the middle has a few runs left.

These however are beyond shoe polish.... they need a little rubber cement first!

JK....

I would have only run the top photoed one a few more runs on the rear of a FWD car.
