replacing tire on one side - how much difference
Just found a nail in rear tire during brake fluid flush and inspection. Can get the one tire replaced under road hazard, but do I spring for the extra $300 plus tax for the OTHER side? if I don't, the new tire will be 9 or 10 32nds (I think that is Michelin Super Sport new) and the old but good one is at 6/32.
3 or 4 32nds inch doesn't seem like "much" to me and I think I will burn maybe that much after 6 hours of hard tracking. I say save my money for next full set of rubber. Just curious if the stability control nanny will freak out over that difference...
about 1% difference in diameter / rolling radius

I had to get the new tire from a different vendor b/c it's under warranty. Would you guys do it for the same price even if it's a newly-mounted one from somewhere else?

Do you expect to cover S&H to and from? Don't you have a shop in your area that can do this?

I am not shipping the tire anywhere just asking "in general" what his policy is since he chimed in. Wondering what a good shave costs these days...
Unfortunately the local vendor must mount the new tire not hand it to me, and they do not shave, so I"m just going to roll with it. I'm sure I can find a local shop to shave it if I really want.
thanks!!!

In dry conditions you would be hard pressed to notice a difference. In wet the older tire will lose grip in standing water before the newer tire with deeper tread. Don't be an idiot driving in the rain and you should be fine. ABS & stability control generally is unperturbed by mismatches of diameter of less than 3% even racing.
My avatar picture is racing on slicks in the rain, would have loved to have been on your mismatched street tires for that race - rain started during race.

if you do go new, that is not a difference to cause any issues, (diameter-wise) other than having a new tire and a used tire on the rear of the car.

In my early days, I put a new tire on my front-right and I thought I had a few more cycles available on the front-left.
Bad idea.... In a heavy braking zone, the front-left (with less good friction) locked, and the sticky front-right kept braking. Car did a snap spin at 100+ and pulled the car right. Luckily it was in a wide track and right hand turn (T1 at Watkins Glen) so I didn't hit anything. If it had been in a left hander, I would have seriously damaged the car.
If there's any serious wear on the "good" tire, I'd replace it too and keep a matching set.
