the reason i have not really checked my tires before hand is ive had them for labout 3months and with my round trip from base to home is 1200 miles they add up rather quickly but yes since you mention it somewhere around 3k miles i was hydroplaning real bad coming back to base. i was only going 60 too and since they were new i never really thought to look... on another note i know they were not overinflated bc when i got them and shortly after i checked the pressure and it was 32psi in the rears. granted i know i prolly should have checked the whole tire out sooner but those 15hr worknights for 2 months had my mind elsewhere i guess. worst part is i still wash the car everyweek and never really checked. guess you live you learn..
