Help with weird tire wear on Pilot Sport Cups

--------------------------------------------------------------------------------

just had to replace both rear track tires not sure how many cycles i got but the wear is extreme on the outside of both tires. I had swtiched from left to right to try to even out since far more right hand turns and the left side normally wears first.... the car has H & R springs, had an alignment about 30 months ago, something tells me I may need a new alignment. ...what does heavy wear on the outside of both rear tires indicate to you guys ?? It is about 1.5 to 2 inches really worn down ......I am running Michelin Pilot Sport Cups and the sizes are 245 40 17" on Fiske wheels...thanks in advance for any help or advice

Air pressure? Alignment out of whack? Or do you drive like this at the track?

what hot pressures do you run? proper alignment for the track and weight balance is a must. too much flex in the cab?

Jim Michaels

The wear sounds like insufficient negative camber. After 30 months an alignment is past due anyway.
