What tire size is original?

I was wondering what tire size is correct on the truck to make the speedometer on the truck? I have three 235/75 r15 and one 225/75 r15
on mag wheels. Need new tires and possibly new wheels.

Thanks for the input

Matt

Matt,
For a 15 x 5 rim, the manual lists a 6.70 x 15 and a 7.10 x 15 tire. A
good tire shop will convert these sizes into the new nomenclature. I do
believe that the 225/75 x 15 is close to what you'll need.

one thing youd need to know is if your truck came with factory 16 or 15 inch wheels. any idea?? im thinking it was a 215-225/85/15 that was equivilent, not a 75 series. or a 205/85/16. you can check your speedo pretty easy, at 60mph you should go 1 mile a minute, find a road with mile markers on it and go play. with my 31's i do a mile in 58 seconds, thats close enough for me.
