If you really want to go back to a 15, you will need back spacing around 2 5/8 inch on what ever rim you chose or a space(1.5 in) that will get the rim away from the caliper. that will give you the clearence to run the 15 inch rim aournd the calipers. Personally my next rim is going to be a 17inch to get better tire choices. It has been suggested you could girnd the caliper to make them fit, but I think that is not safe. later robbie

I guess I am confused as to why anyone with a 16 inch wheel would want to go to a 15 inch wheel. There are plenty of 16 inch sized tires out there.

Edit: There were two threads on this. I merged them to a single Thread and change the title

I put my 15" wheels with 35's on the FZJ from the FJ40 just to see, They rubbed on the front clipers, They were aluminum rims, I would imagine steel wouldnt be quite as thick on the inside.
I dont know why you would want to get 15's, But its your vehicle, The reason being 16" have a better load rate...IIRC
Good luck

315s are about as big as you can go in a 16" rim that is why I'm sure he is looking. Steering becomes and issue with the less backspaced wheels as when you turn your tire takes out your flare and fender. The clearance problem I found to go to the 2 5/8" as powderpig suggested is in the rear and then the steering problem comes in the front. So it is sort of tough unless you are ready to trim.

I checked sam's off-road and tire rack to compare prices

Sams

Truxus MT

35x12.50x15 $164.25 $657.00

35x12.50x16 $189.28 $757.12


TireRack

BFG MT

35x12.50x15 $167.00 $668.00

315/75 R16 $212.00 $848.00


Goodyear MT/R

35x12.50x15 $193.00 $772.00

315/75 R16 $217.00 $868.00


Or, the short version

Truxus, save $100 by having 15" rims

BFG MT save $180 by having 15" rims

Goodyear MT/R save $96 by having 15" rims.

Certainly save some money, and get some more options for tires running 15's

Thank you for your help everyone. i am going to try the backspacing to try and put them on. The main reason that i am trying to go to 15 inch wheels is because of the lack of sizes available for 16 inch wheel. i know that they are out there but i am stationed in okinawa japan and there are plenty 15 inch tires around but no 16's. so thats again. okay if all fails how much can i grind off the caliper.
