Took the old tires and rims of the old truck(85 F150) and want to put on the newer truck(92 F150). My question is going from 235/75/R15 to 265/75/R15 what if any difference will I see in the speedo and trip?????
Well, let's do the math.... you're going from a 29" tire to a 31" tire. So, you'll be about 6-7% slow on the speedo. 60mph on your speedo means you're going about 64mph. Your trip will also read the same slow too.
