Get pyrometer, pretty cheap now. Flog on curves, then pull over, compare sidewall tread temps to center tread temps. 3 readings per tire, inner tread near sidewall, center of tread, and outer tread near sidewall. Should be pretty even across. If sidewalls hotter, add psi and repeat. Tedious, but works. Done for years. OCD is good thing. If outer front sidewalls are warmer, consider dialing neg camber, but use pressures to tune most out. HTH

That's good info. Do you have a link to an article on this subject and procedure in more details? Can you recommend a good pyrometer? The outside temp at where I live now fluctuates up and down like crazy and it's hard to decide on a psi.

How can they warrantee them? what if somebody went and did burn outs?

I'm old, learned from racers and Pirelli engineer 35+ yrs ago. Pyrometers cheaper now. Need stable outside temps if possible. Here's a starter. Probe vs laser probe is more accurate, but if you're quick it's not bad. Doing one axle then other saves time too, and won't mire you in chasing numbers as handling changes with pressure changes. http://949racing.com/using-a-tire-py...49-racing.aspx
Treadwear on mine was even, and gone at 14k miles. Burnouts don't wear evenly. Driving really hard with appropriate pressures and alignment is easy to see. PS3 was 20k mi warranty. I got 14-15, so I got 1/4 rebate.
PSS has 30k guarantee. I've got 12-15k on a set about 2/3 gone. Wearing much better than PS3. Far better in rain and extreme heat, tolerated 150-160 degrees on hard summer run about 450mi.
So, burnouts no. Aligned, good pressures, and hard use, yes. Be nice to your tire dealer and document miles, rotate if able, and remember only thing between your azz and the pavement is tire. FWIW

Now I'm back to thinking the pss tires when I'm ready, lol. I know they are great as I had them on my last car and the car felt so smooth and handled so well.
