user removed · 07-24-2013, 11:40 AM

I have measured tread depth with a dial caliper after 25k miles on brand new tires and there was no difference in tread depth across the tire after running sidewall max from the day the tires were installed. The pressure on the sidewalls is the same as the tread.

Tires will last a lot longer since you are reducing heat from friction in the tire as it flexes.
Ride quality is another thing altogether. My Fiesta does not seem to mind higher pressure at all.

I'll run sidewall max until I can't drive anymore. The wife doesn't complain about her Sorento with 42 PSI (sidewall max is 44), and she likes to complain about just about everything you could imagine.

regards
Mech
