  • question for anyone who has kumho ecsta supra 712 255/50/16

    What tire pressure do you keep them at? I want to make sure they don't wear unevenly. The factory recommendation of 35psi appears to make them overinflated and wear too much in the middle. I've got them at 32psi cold now. Anyone?

    I haven't checked since I got them, but i assume that they're between 32-35 psi. also, some is the tread is depper than others. that may be fooling you into thinking it's wearing more on the inside.

        42 is a little high. I keep them at 35 and I'll see how they wear. I just got them so it's hard to say right now.

          I thought car recommendations override tire recommendations?

          Dunno... I just lowered mine to 30 today...

          They were at 35...

            So if you put on skinnies and nittos you keep both at the same pressure as the regular tires?

              that is a *very* special case

              how about we stick to radial tires for this one (well, skinnies may be radials, but slicks aren't)

              Edit:
              Checked discounttire.com -- according to them you use car manufacturer's specs based on the size of the tire. PSI generally raises w/ the size of the tire. If I had to make a guess, 32-34 would be about right for this tire. Will call them tomorrow & ask (they have a list).

                    My Kumho 712's are 245/50/16....but I keep them at 33psi for regular driving. That's also what the goodyear folks told me.
