    Tracked tires replacement

    How do you guys (and gals?) determine when to replace tires that have been tracked? I still have a good amount of tread on most of my tires (the stock pilot sports that came with the car) after 4 track days, but there are parts of the tire that are worn below the recommended 4/32 tread thickness level (or even 2/32 for that matter)--specifically, on the front tires (a) the outer half of the approx. inch-wide center tread strip is largely worn off and (b) the very outside edges of the tire's treads are worn off. Not sure if I really need to replace the tires yet or not.

    Sounds like those need to be replaced. Always respect the wear bars on the tires.

    Street tires you can go by tread and I agree yours sound about done. Track tires are more likely to wear out by heat cycles and not necessarily tread. If you want to increase the fun factor try some R compound tires on the track.

    I agree, better to just replace them or save them for a burn out contest at a local car show.

    Heat cycles are the hardest on them, check for sidewall cracks or stress, and if the tires are at the wear marks at any spot, usually is best to replace. If there are cracks in the sidewall, I replace as well.

    I, and others, have been trumpeting for a long time to pump the front air pressures up to mid 40s, hot. The edges won't wear if you do...

    For track purposes or all the time?

    Re: Tracked tires replacement

    I run 40's + PSI on the track. Because I am not destroying $800 worth of tires for a few fun laps. The tires hold very well at higher pressures.

    Re: Tracked tires replacement

    I agree. I've started upping the psi after the initial outer wear and will keep doing that going forward As for the tires I've got (shown in the photo) would you guys run these tires on the track still or replace them now? My gut says they're good for another day or two.

    Re: Tracked tires replacement

    Generally speaking, when I was doing 20 track days a season,... I ran tires until the cords were showing. "corded"

    Re: Tracked tires replacement

    The problem that I had with higher pressures were that they'd climb so much, I'd get overpressure warnings - 50+ PSI. Secondly, they chunk those center ribs like his are. On most days now, I leave them at 32 for driving, then they heat to around 40-ish during track sessions. No uneven wear, and good traction. This is with the PSS's up front though as opposed to the PS's.

    You can drive them normally for awhile. I just wouldn't go crazy on a back road with them...
