My son just picked up a 93 F150 XLT to run for awhile it has the 302 and is a auto and 4wd. reg cab with the 6ft. bed i was wondering why his truck came from the factory with 265/15 tires ? all the ones i have seen including a 1993 F150 XLT i had ( same moter size and trans. mine had the 8ft box and alminum wheels and two tone paint etc. ) came with the 235/75R15 tires . even some of the tire places i have called ( needs new tires ) have told me i am wrong with this size that they came with 235's but right on the door it says 265's. do you guys know why this is diffrent ? is it some kind of heavy duty or ? would really like to know. thanks for any help with this , its not a big deal but its just got us wondering why its diffrent !
