speedo question
ok heres the deal, i have a 79 100 with a 302 auto and a 9". My speedo is off at 60 ( ie if im doing 50 on the speedo im actually doing 60) there is no jump og the speedo which tells me that the gear is ok but i am running 235/75r15 tires. they seem to me that on my 77 150 sc that i had i ran 31x10.50/15 and that the ones on my current truck are to small, causing the difference. i have only had this ruck for amonth and i paid $400 for it and have used it as a daily driver since, with very little work. so any information will be helpful.
