Any well made tire should not wear unevenly if it is run at the max psi so long as the cars alignment is good.
Most professional race car drivers will tell you that in their cars at home they run their tires very close to the max psi if not at max, or at least the ones I have known. I also saw an interview with Mario Andretti recently and he said the same. So I lean towards the max.

 

last time i checked most race cars run slicks so they wont have a treadwear issue.and the reason they are running max is because they are racing not street driving.also overinflation will wear the center tread down faster than the rest of the tread just ask any tire manufacturer or decent auto tech

 

true, but the max pressure listed on a tire is not considered overinflation. One example is our trucks with the 20" wheels and the goodyear tires. the tire says max pressure is 44 psi and I run mine at 42psi and have over 25k miles on them and they are wearing evenly with equal tread depth across the tire. Now running them at 50 or 60 psi would be considered overinflation but if a tire says that the max psi is 65 then you can put 65psi in it and it will not be overinflated. Not arguing that overinflation of your tires will cause the center to wear faster, I'm just saying that running the max pressure listed on the tire will not cause this like others are trying to say it will.

 

i just had mine mounted and rode around for a couple days. the tire ligh came on so i check all pressures. they had all like 32psi. i bumped them to 36 and they ride lot better i might go up to 38

 

Bad info here. It is always best to use the label on your truck for the proper inflation pressure, not the max load spec on the tire. You can safely fill to the max load spec but the tire will wear out faster. The vehicle label is what is considered optimum for your vehicle and used to determine over and under inflation of the tire. Any tire manf will tell you this. An example is below.
