Default 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?

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.
