higher tire pressures
 

I was told that by running higher inflation on my Z's tires (5-7 lbs. under max. recommended inflation specs) it would help with the feathering issues associated with my car. I inflated my tires to 45 lbs. so far so good. Anyone have experience with this? (daily driver, no high speed stuff involved) Thank-you!!

No. The wear will be greater in the middle of the tread, the ride will be worse, traction will be worse, etc. Fix the problem by getting a proper alignment, replace worn parts, etc.

Inflating your tires to 45 psi is foolish. You will wear your tires unevenly ( the center in this case) and possibly dangerously since TCS, VDC, and ABS are untested at this inflation.

You should drop your inflations to specifications ASAP.

I keep mine at 35 psi (cold), check in a.m. before driving because the psi goes up pretty quick as tires warm up and may get like 40psi on a hot day if I check 'em while hot. Checking cold is what I was always told anyway, more consistant.

Every vehicle has the sticker in the door for specified tire pressure. Ours are 35psi in this case. Easy as that and post #2- replace your worn parts: bushings and more/align = finished.

Yes... That is the correct way to maintain psi. You do not want to go much below the recommended psi; that is why we are advised to check when cold. In very warm weather the psi will creep towards unacceptable, but that is the reason we run summer/performance tires. This tire type handles the extra inflation in warm weather and repetitive track runs. --Spike

Best to try and rotate the tires, have alignments checked, and maintain proper oe pressures to help promote the best/most even tire wear.

^^ We can’t truly rotate tires since our cars have a staggered setup. Did you mean we should swap left and right sides on the front and the rear?

Keep em at 35-36psi...

I feel he means rotate like normal but what i have to do is flip them once a while .

Yes. If directional they can be dismounted and remounted on the opposite side of the car, if asymmetrical they can be moved left/right w/out dismounting. Something is better than nothing. Front/rear isn't an option either way.
