Rx3 wheel tire spacea available ?
 

Hi friends can anyone help me here I am looking for the biggest tire I can use with a 15x7 wheel without cutting anything down there or if a 15x8 wheel fit well with which tire?

There are ALOT of variables to your question... more information is needed. Stock springs? caster/ camber plates? back spacing of your wheels? I dont think a 15x8 will fit without some modification no matter what the back space but i could be wrong

Yes they are stock springs the backspace is 3.5

I have 73 rx3 with 15 x 8 ROH wheels and backspace 20.

235x 50 on back and 205x 45 up front

using lowering king springs up front.

the back set up is fine, I think 235x 60 would still fit.

the front fit works, but 7 inch rim would be easier especially with any less backspace. Had to adjust the fender a little, but am still using the original stainless wheel arch trim. Had to remove the stage one blocks to make it work.

The 4 x 110 bolt pattern was problematic. would like to run 8 inch rims in back and 7 inch up front, but rim selection is limited.

Bolt pattern change would open up more possibilities. in retrospect I should have changed up the dif to a shortened ford 8.8 and match the front pattern to the ford pattern.

depends on if you ever plan to make more than 250 hp. If so change out the diff first.

I hace a 9 inch Ford diff

This muy 15x7 wheel withh 215/60 wheel this si muy Space available it seems it wont fit a 15x8 wheel
