What are the sizes that fit on 1st generation four runners? I mean as far as size,bolt circle and spacing. I'm looking at some wheel and tire packages and don't know what size is for what. Little info... I'm looking at 15"x8" wheels and 31x10 tires.

 

6 on 5.5" bolt circle. On solid axle, stock is 3-3/8" backspacing, about 3-3/4" is the max. On IFS, 4-3/4" is stock b/s, you don't want to go much less than that. You can run 31x10.50 on the stock wheels.

 

on a 31x10.50.15 tire
31 is your rough outside diameter meaning they're about 31" tall
10.5 is a 10 1/2" wide tire
15 would be the size of the hole in the middle so 15"

on a 15 x 8 rim
15 meaning the rim is 15" tall by itself
8 is the rim being 8" wide.

For bolt pattern our toyotas have a 6x139.7 bolt pattern which is 6 lugs (holes for the studs) x 139.7 being 139.7 mm from one wheel stud to the opposite side wheel stud

hopefully this helped you out

 

thanks for the information. I have been looking all day at tire and wheel packages.
