I have run into this problem before with the G-60 IMCA... What I did to correct it was reworked the weight distribution. Once I reset the car, it no longer feathered them. They wore a lot more evenly.

i usually grind or reverse them at the first hint of feathering...question for you..mine usually feather on the inside edge of the rr and the outside edge of the lr..is this normal or is it too much roll steer..thanks.

You need to take your tire temps and look at them, sounds to me like the tires dont have enough air in them

thanks jammin..we are on hoosier d40's...usually when the track gets dry slick and is smooth we run 9 in the rr and 7 in the lr, right or wrong? now that you say that i do notice the edges being a little hotter, not a lot, but hotter, thanks..also you always seem to have knowledgeable answers on here, appreciate your input, keep up the good work

Check the temps...if the center of the tire is cooler than the outsides, then you just answered your own question.

9 seems a little low for the d40, I typically run 12 at the lowest on the d40. If i run an h40 i will drop down to 9. I had troubles blistering the d40 if i went below 12 on the rr. I have run as low as 7 without any problems on the lr.

we run d40s at one of our tracks and found that (start the main at ) 9 lr 12 rr and the temps are even and seem to wear fairly even with about 80lb heavy on the lr
