I am thinking of trading some stuff for a set of 15x10 (4in backspacing) wheels for my 4runner. I have 33x12.50 BFG ATs on 15x8s now & was thinking of selling my 33s & going up to a set of 35x12.50s but I have read some interesting stuff about 10.50s not being as heavy & rubbing less. I really want the 10s to make the footprint of the tire wider & the extra 3in wider track couldn't hurt anything.

 

10.5's would obviously not be as heavy or rub as much, due to being a skinnier tire. However, you are losing footprint by going to a skinnier tire.

 

10.5 tire on 10 in. rim you have to be careful airing down, you can lose a bead much easier than on an 8" rim

 

DeathCougar you are correct but it will still have more footprint on a 10 then an 8. I have not as of yet gone below 20 psi on an airdown. Rocks are not my fav thing. I just like to trail ride & here in Alabama we have clay based mud that can be a booger sometimes. I will do some rock crawling but just baby stuff compaired to what alot of you guys do.
I guess the question I should ask is what would be more capible offroad
the lighter 35x10.5 on a 10 in wheel or the heavier 35x12.50s with the larger foot print. It also seems that I can find 35x12.50s cheaper then the 10.50s which is crazy

 

There was a pretty big debate a while back about wether pizza cutter tires or wide tires were better in our mostly gutless trucks. I think the general consensus was that pizza cutter (tall, skinny tires) were better for less horsepower but that a wide contact pattern was good for high horsepower applications where they had the power to keep wheelspin.

Also, don't BFG AT's suck in mud?

 

I'd imagine the tire would slip badly on a rim that wide if you do any sort of wheeling at all...If I remember right Mt Goat had this problem and he couldn't keep his wheels balanced for the tires slipping around them. 10.5 tires aren't even designed to be on rims that wide and some shops may not even mount them...

Do yourself a favor and step down to an 8" rim or step up the tire size to 12.5 wide...10.5s on a 10" wheel...

 

Yes the BFG AT suck in thick mud

 

I worked for Discount tire for 2 years and mounted quite a few tires in the time I was there. All_Terrain17 is right for the most part, you'll risk spinning the tire on the rim which is very bad for the bead of the tire and can cause more problems than balancing issues. IMO the looks of a 10.5" tire on a 10" wheel looks terrible, listen to these guys and go with an 8" rim or step up to a 12.5" tire.

 

^ what he said.

I'd use 8" wide rims no matter what width you decide.

Pics of 33x10.50x15's on 8" rims...




Even an 8" rim is kinda pushing it with the 10.5's

 

D@mn rocket you keep that thing CLEAN underneath!

EDIT: Forgot it's totalled

 

I really want the 15x10 for the foot print. I gonna see if I can get a set of big 33x12.5 or some 34x12.50s

 

it looks stupid.
