38 psi too much for Hankook Dynapros?

what does the cold psi limit 60psi, when on the same tire it says 45(i think) psi

i tired to look it up on Bing, but did find that actaul meaning.

something about after u start driving for like 30 min ur tires inflate themselfs or sumthin crazy like that

 

when you drive your tires heat up, heat expands. so if you havent driven in a couple hours and its cold out and max psi is 40 cold dont go above 40 cause when you drive that will probably bump up to 50. thats how tons of people get blow outs here in az cause it gets so hot

 

ooooohh, I see said the blind man.

 

You are more likely to get a blowout from under inflation than over inflation. An under inflated tire will run much hotter from increased friction. I run mine at 40 in the warm months and 32 in the cold. Haven't had them long enough to comment on wear, but airing down for snow makes a huge difference. Last year I took my saturn ion with snow tires aired down to 20psi out in the Maryland blizzard, she never let me down!
