All---
I had a terrible shock yesterday at Sacramento's round 3.
After 5 runs (3 runs of my own and 2 of my co-driver's),
both front tires started showing cord on the sidewalls,
right at the shoulder. I'm running Dunlop SP8000s with
1500 miles and about 30 autocross laps on them, inflated
to 45 psi front/42 rear. After the 5th run I added another
8 psi each to the fronts; one lap later they were still
rolling over, so we bailed out and drove home very
cautiously.
So whyinole should near-new Dunlop's give out so quick?
And why would they roll over with such high pressures?
I made sure to check my tire gauge against a couple of
others, and it was in agreement.
These tires are marginally larger than the stock tire
(205/50 R15 vs 195/55 R15, a +0 fitment that Tire Rack
said would be just fine). Everything else on the car is
totally stock.
Do I have some heinous suspension problem that would cause
this? Or have I just had the bad luck to get two faulty
Dunlops? Can anybody shed any light on this?
