Is anyone having problems with the Hoosier A40 tires, We have tires that the tread on the tire seperates from the tire. This usually occurs on a dry track and is usually on the right rear, but Saturday night both rear tires lost pieces of the tread. Just wanted to know if anyone else is experiencing the same problems with Hoosier tires.

we have lost chunks if we get to aggressive with the grooving iron and we only dyno at 350 hp

I've had the same problem in the past, I talked to Hoosier and they said to low airpressure. Went up a couple of pounds and never had the problem again. Just a question, but why would you dyno a 350 hp motor???? couldn't you guess that much and leave it go at that??? Just wondering.

I've run both the A-40 and D-40 on the rear with 5lbs in the left rear and 7lbs in the right without ever chunking out a tire, but I've seen other guys do it like crazy with 12+lbs across the rear. Maybe I just don't have enough horses

with all the restrictions on our motors and how competitive it is every little bit helps it also is a factor in selecting gearing. If you reasoning is right why would a go karter dyno his motors. Remmember the lower the overall HP the bigger the percent a 2hp gain is. Does 2 hp mean anything to someone running a 650hp motor NO WAY but 2 or 3 hp on a 300 hp is a lot more of an effect. the difference in the top ten in national points in our class was less than 60
