31x10.5-15 Tires on a 2000 Blazer LT?

I'd like to goto a wider profile tire on my stock 2000 Blazer LT and I was considering the stock size for the S10 ZR style 31x10.5-15

My question is, does anyone know if I used them on my stock alum rims, would they hang out very much from the fender wells or any problems with clearance on turning?

Thanks for your help in advance ...

I looked at the same thing and a 2" body lift is required to clear the tires.
Have to unbolt the entire body and lift up and insert new poly spacers.
They have gap adders for the front and rear bumper 2" spaces this creates.

Thanks. So much for that, I didn't think the size increase was so dramatic to need to lift the body.

Oh well, does anyone know what increased width and or height tire I can use on the stock 15" rims without the need to alter the body height?

Thanks in advance for any responses ....

30x9.50R15


31 might fit, but will rub when wheels are fully turned. Wheel spaces will solve that. Not sure at full suspension articulation.

i'm runnin 30 9.5 15 mud tires on my stock wheels no lift it seems the prevouis owner cut a little metal out of the rear wheel well to reduce risk of contact with the tires i bougth em with 30's they are fine but bear in mind if u are cranking the steering all the way to lock while moving such as over bumps it rubs a little not much but engougth to take the paint off the sway bar

Our wheels will fit the 31 x 10.5" tires. Although they will fit with a 2" lift most companies recomend a 3" lift to prevent rubbing.

If the gas prices weren't outragious I'd consider lifting mine with a 2" suspension lift, 3" body lift and run 31" tires. Now I'm considering getting a small 4 banger 4x4

The body lift is not real hard to do if you have a good high lift jack and an air impact wrench . I did mine alone in a few hours . But even with all the lift I have , this size still rub and the older blazers have more tire clearance around the fenders . Rob

I could not run the 31's on my truck, 98 Blazer LT, too much rubbing, the 30's fit (barely) you will like them. You can also go with 265-70-15, those have almost the same with as the 31's with no rubbing. I opted for the 30's because they are C rated tires and held 50psi instead of 35psi, so now when I am towing or got the rig packed it runs smooth. Good luck

Thanks for the responses ....

I just ordered 4 Firestone Destinations size 255/70 SR15 from the Tire Rack ...

They won't ship til tommorrow so I just want to confirm that I shouldn't have any issues with rubbing going to the slightly larger size. I can still cancel the order if they will be too big. It was mentioned earlier that 265/70 15s would work fine so I assume the 255s should be ok.

Your help is appreciated ...

One more question, since the tire is a slightly taller tire, am I correct in thinking that my speedometer will read slightly slower than I'm actually going because the taller tire will have fewer revs per second?

I really can't promise you that your tires won't rub at all, however I really can't see it being all that bad.

Your right about the speedo reading.

Thanks for the response. I have my fingers crossed. A small rub won't be a problem, I just hope it's nothing major requiring any mods. An earlier poster said 265/70 R15 would fit so I assumed a size smaller would be fine. I'd hate to have to ship them back to the Tirerack.com

Anyone out there running 225/70 R15 or 265/70 R15 on a 2000 Blazer LT or the like ?

There is a few people running them on here, do a search and you will find it. I would go with the Toyo Open Country T/A

Thanks for all of the help, I had my 255/70 R15 Firestone Destinations LEs installed today and I LOVE them. Just right, fills out the fender wells and no overhang or rubbing. Thanks again ....

How about installing 235x75x15 Michelin LTX MS tires on a 2000 2x4 model ? (original stock wheels)

Would the 75 make the tire rub? I now have 235x70x15

Thanks for your comments !!

no it should not rub it will only be about a half inch taller what are you looking for ?? more grip via wider tread? maybe you could try 245/70/15 or 255/65/15 if you can find such however i am not sure if the 255 will go on without rubbing but if u want hight then maybe 245/75 15 that would add a inch or so...but rember when u change tire size u change correct air pressure

As requested photos of my 2000 Blazer LT with 255/70 R15s on stock rims .... No rubbing at all ... The photos don't do it justice, it really looks much better and the wheel wells are filled out nicely with the slightly larger size ...

I dont know what you were worried about.
Today i just installed 31 x 10.5 tires on my regular 2 door ls 4wd blazer.
I have about a inch of clearance everywhere.
I have a inch between the tire and frame with wheels cranked one way and i have a inch between the tire and torsion bar when fully cranked and i have a inch of clearance in the rear bumber.
I know it wont rub cause i put my truck at full artechulation or however you spell it and i got no rubbing so im pleased with my tires.
And they talk to you when your driving.

31's do rub they have too my 30x9.50 BFG Ko's rub at times. To make 31's fit you have to crank the torsion bars up to a limit where you will go through front end parts fast. Not a good idea. Sorry just notice this was 4 years old.
