Tire Pressure.
 

Alright guys, I have a very important question. At what PSI should I run my new tires at.

Specs -
Wheel size: 18x8.75
Tire size: 245/35/18 Michelin Pilot Sport A/S 3.
Currently running at 35psi, and was wondering if 40psi would be better?

What exactly are you trying to make better?

I want a stiff ride, with good traction and less wear and tear

Theres a fine line between good grip and overly pressurized sidewalls.

I usually fill all my tires at 32 cold. that usually brings it up to about 36ish hot. I let it drop until 30 cold before I refill them again. though, I always check every week to make sure the pressure is even on all 4 tires.

There's no magic bullet. If you want to optimize grip and wear, you'll need to be monitoring the tires more closely to see what they need.

If pressure is too high, you'll see warmer temps (and more wear) in the center of the tread, too low of pressure and you'll see warmer temps (and more wear) on the outer edges of the tread.

By the sound of it, just stick with 35psi and stop over thinking it.
