Anyone else having problems with the 2nd tread in from the outside chunking out. It is only that row. After a 8 lap heat the tread raises and is spongy like the rubber is blistering at the base of the tire. By the end of a feature it has nearly the whole 2nd row chunked out. We are starting with 13-14psi and siping less than 1/8" deep. Seems that its worse when there is moisture in the track. Any thoughts/advice would be appreciated cause this is getting expensive.
Quit siping
yep ,don't sipe, especially on fast tracks.. but you don't need to sipe A40S...maybe after 4 or 5 nights on a right rear
not having these issues. agreed - i'd stop siping
Raise the air pressure a couple lbs.
Don't sipe
I only sipe them if they harden up a bit, or I have moved them to the front of car.
I would NEVER run one on the RR.
if it run them on the LR new, I never sipe them.
what do one of these punch new?
I have seen 40-50 new .
kind of a wide range.
Like everyone said, quit siping. It tears the a40s apart. Its also trash on the right rear anyway. Bolt on an H.

I Really like the H on the RR at all times. just have to know how to get them to fire quick.
Even for 2 laps at the gateway nationals?Quote:
