What tires size? 15"x9.5 on 1st Gen?
 

i know a 245/45/15 would be the size diameter but not sure what the width would be.... i also might want a slightly smaller diameter overall. Anyone have some ideas?

so was looking into the Prime website and found the wheel in their discontinued section.

Learned two things.

1. I saw it only came in 16. Went out and remeasured, sure as hell, its a 16 inch rim...grr

2. supposed to come in only 7" width. The distance between the inner beads are like 8.5 inches.

I emailed them too see what the deal is

okay so a 225/45R16 tire will be the best choice to fit the FB

okay so i guess it IS a 15 inch wheel and approx 8.5 inch width. Guess a tape measure is the way to measure a rim

In similar thought... What would be the largest width tire available for 1st gen and 9.5 width on 15s?

for drag racing? or for cornering?

I guess street/track.

I should of asked, "What is the widest tires for 15inch wheel?" Not truck tires :)

i was using this as a guide. may help

I should clearify again..

I want to put some wide wheel on an old school rotary.. But not sure what the widest tires for 15 inch that would fit say... 10 or 11 inch wide 15s.

Your post kind of reminded me of it.. Normally on 9.5 inch wide rims I would like to get 265-275s on it... But thats usually for 18s.. I'm sure for 15s and higher side wall you might be able to get away with bit wider.

well for the 15x8.5 inch wheels im going with something like a 225/45. Should have only a little stretch.
