31/10.5/15 on stock blazer rim?
 

pretty simple, will a 31/10.5/15 A/T or M/T fit on a stock blazer rim with no issues?

well check out my pics......no rubbing or anything....just make sure u remember there is like no space left in the wheelwell so keep that in mind before you start running over cars

RE: 31/10.5/15 on stock blazer rim?
 

Yes that size tire will fit on the wheel no problem, fit under the truck is a diferent topic.

The general rule of thumb is 4.5". You can go up to 4.5" wider then the rim wideth. If your running a 15x7" factory wheel, the maximum tire wideth is 11.5". Tire diameter doesn't matter except to fit under the truck. 15x8" and 12.5" wide will fit on the rim.

A realy good source is the tire manufacture, they have recommended rim wideths for every tire they sell.

Yes they fit.
As long as you dont forget you have them on there. Big dips in the road and speed bumps can make them rub. It kinda bent out the metal on the fender a bit.

Nothin a rubber mallet cant fix though!

If I do decide to get some wheels too, would I be better off with a 15x7 or a 15x8? Would the wider 15x8 make the rubbing issue worse?

anyone? anyone? will an 15x8 inch rim with a 31/10.5 tire rub more than a 15x7 rim?

The answer to that question lies in the backspacing. IF, and that is a big IF, you can find an aftermarket rim with 5.5"-6" of backspacing, it shouldnt be too much of a problem with 30" tires. The issue with oversize tires and/or wider rims is where the tires are located in the fender well. Or rather out of the fender well. The most common place for the tire to rub is on the outside edge of the fender, especially in the back of the wheel well. After that the tire will rub the frame at full lock. With a rim that has less backspacing it pushes the tire out of the fender more. This means it will hit the back of the fender well.

31" tires will rub on a factory set-up. Like he pointed out it happens over bumps. Forget about using it off-road if your already rubbing on city streets. In my book, a 31" tire doesn't fit if it rubs. To make a 31" tire work, add a 2" suspension or body lift. Or be prepared to eat tires and sheetmetal.


The short answer YES!!!!!

even with a 2 inch body lift, wont the tire still rub on the frame at full lock? or i guess with a body lift you could use less back spacing because the tire wont hit the back of the fender well. is that correct?

RE: 31/10.5/15 on stock blazer rim?
 

what kind of back spacing is this running?

i take it those rims (crager soft 8) dont have much because of how much they are sticking out? that truck has a 2 inch body ift as well

Having wheels with a different backspacing should solve the problem of rubbing the frame while turning.
But, it wont help at all with the tires hitting and tearing up the fender.

Its been worse than that before but I always pound it straight with a rubber mallet. The tires also gets chunks cut out of them from the metal thats sticking out.
