That chart is from 2005. We need an update that has a second color dotted line on there

I know this is a little off topic but I saw a set of cup 2s on the rear on an AMG coupe convertible yesterday at Sonoma that were worn past the 2 deep tread grooves after just 4 sessions. They started the day with just some normal street wear according to the car owner and the fronts would somewhat attest to that. He knew he was running too much air in them (adding to the fact it's a heavy 550hp front engine car.) I guess this would come under "too much heat" cycles.

Yeah, you gotta watch your hot pressures and keep them at a moderate level. Also, a good cool down lap is important for both tires and the engine/tranny/brakes.

to the OP, it really depends on a variety of factors. When I first started to track my cars I could get an entire summer out of a set of tires. However, as the years went by I got better and started to explore the limits of my cars, the number of days I could get out of a set started to decline dramatically--now I am lucky to get a weekend or at most 2 weekends out of a set. The other thing that plays a major factor is the track characteristics. Some tracks destroy tires, others don't. Also whether a track has numerous primarily right sweeps/left sweepers will also determine longevity. So your speed, the track play the biggest factors.

Without a doubt if you are traveling to tracks that are not close to home, pick up an extra set of wheels. For example, just this weekend I corded a rear at NCM, thankfully I was able to swap it out with a spare wheel I dragged along- otherwise my weekend would have ended quite early! Also, as others have said tire pressures are so critical, not only for ideal grip but for squeezing out some extra life from the tires.

Enjoy! Its a fun hobby, but man it gets expensive fast as you get quicker. get ready for tire bills, brake pads, ect ect....surprised my wife hasn't left me yet.

The general sentiment is to plan to spend more money as I get better.. lol what am I getting myself into!

The key is to NOT keep track of money spent. Burn the receipts and keep looking ahead, on to the next "absolute necessity". LOL!

iphilips

Lol, haven't done a single track mile this year and my estimated budget is already blown. So once you overrun the budget you may as well keep going.

Actually I'm doing one better. There are a bunch of 0% APR Credit Card offers out there for 18 months. So I'm going to enjoy using free money for my track days (for 18 months).

DISCLAIMER: I don't recommend you run up CC debt - I'm simply doing it for fun because, where else in the world would a bank give you 0% APR for 18 months to spend on track days.

Thank you Congressman. The government uses a similar concept for the national debt.

iphilips

Not sure if being called a Congressman is a compliment or an insult these days. But, I'd be happy to take more 0% money 😀
