    I've been on the forum a while and while it's abundantly clear the solution is to change tires, I'm not sure I want to. Does that mean I need to do a burnout to get the better traction with MT or Nittos? Not exactly what I want to do on the street.

    I'm looking for advice on how to have some fun accelerating to 65 or 70 on a quite section of road. I can't seem to get enough traction during acceleration.

    Looking for suggestions on settings, tire pressure and how to roll in to the power on the stock tires to have some safe fun and hit a respectable 0 to 60 time. I've never owned a car like this and have about 650 miles at this point.

    I tried it all with stock p zeros. Best I could do on the street was 3.9 and that was basically feathering the gas in 1st and 2nd. Springtime ill be rolling the MT Street Rs to the track and getting a wider tire for the street as well.

    I would be happy under 4. I'm hitting 4.7 and feathering the pedal to avoid spin. What psi should the tires be? I'm at 40.

    I had the 555rs on my first cat. Took them off to trade for my second car. I haven't put them back on yet. The stock summer tires are crap for launching the problem is the width. not enough. The pirellis are actually pretty good for aggressive driving on windy roads and get quite sticky but if you want launch get the nittos. They hook very good on the street no burnout needed not too bad in the rain either.

    Thanks for posting the link. So summer pirellis are just useless on launch I guess.

    The only way I could get under 4 on the P Zeros is to put the shifter in manual and second gear. Once you are going you can slap it back into auto. IMO 1st gear is too low for the P Zeros. Second gear allows you to load the engine more without as much torque to the wheels (easier to feather the throttle). :)

    Nitto's will work better when heated, but they dont need to be to get better traction than stock

    305's will give you much better traction on than 275's just from the size difference.....when im doing 0-60's the first one is typically a waste...spinning too much....by run #2 you should be able to get 3.6-3.7 0-60 on the street if you do it right...i occasionally get 3.5 on the street (a8)

    just get the nitto's on the rear, keep your stock fronts, save your old rears to put on the fronts when they wear out......you wont regret the change

    outside temp is the biggie.....nittos give good traction at 50 degrees....stock tires most likely are dangerous...i dumped my p0's at 500 miles, so i never got to see how they worked......but ive owned GY F1's and know they are crap under 90 degrees...i assume the p0's arent much different

    40 PSI is too high for these tires

    Try 32 which is the recommended pressure

    I managed a 3.8 0-60 with these tires

    also - Suspension in street will help shift weight better

    If your going for your best 0-60 with P-Zero's... you'll need drop the pressures to the low 20's and they'll need some heat in them. Agree shift to manual and 2nd gear launch... street mode on suspension... 1st gear just blows the tires off... makes for a nice smoke burnout though!:D

    I just blow Teslas off at freeway speed and leave stop lights to the street squirrels driving Subarus--they love thinking they are road commandos...

    even with DR's you'll need to drop tire pressure to 19-22 psi for the "best" launch...
