I recently purchased 235/75/15 tires and rims for blazer which is the same size as my stock ones. Except that they have a little beefier tread. Goodyear wrangler..

I'm wanting to put on spacers but don't know which size to go with. Can anyone suggest sizes to go with? I would like to have the rears 1.25" larger than the fronts to make them inline with the front tires..

 

This all depends on what you're trying to achieve. Personally I would have gotten rims with less backspacing to do what you're trying to do and then bought 1.25" spacers for the back, just to even the front and rear.

 

I actually got a really good deal on this blazer and got it just as a recreational only vehicle. I don't plan on doing any hardcore wheeling. It'll be used mostly for a back road exploration rig. The spacers are just to give it a more beefier look..

I would like to pop the tires out as much as possible without making the tires look too skinny..

 

This.


Or 1.25 front and 2.5 back if you're dead set on spacers all around.
