I have 15x8 rims and don't plan to buy new ones anytime soon, but I'm having a small problem because of it. I cannot put on 285/75's because I don't have a 16" rim, and the only tire out there in a 33 is a 10.50 (and I want something a tad wider).

So now I'm considering going with 33x12.50's over 33x10.50's, but I wonder if I'm going to have issues with the tire itself on the rim as well as rubbing.

btw - I will be running an OME shock/spring combo on a 98 2wd.

 

33X12.5's will fit on an 8" rim no probs

 

sweet, thanks

 

I sure hope that it is not a problem as I have been doing it for 20k miles or so.

Seriously though, the rule that I try to use is an 8" rim can handle up to 12" wide tires without beadlocks while a 10" tire belongs on a 6 or 7" rim. A 10" wide rim, while wheeling, should handle all tires wider than 12.5" excluding the ridiculously wide swampers.

 

Here's a question for ya................where are you getting these tires mounted at??

A while back I tried to get a 31x10.5 put on my 6" wide steel rims and none of the tire shops in my area would do it. They all told me I had to have a 7" wide wheel minimum or they'd refuse to mount them. Most of em said it was against their policy.

Also when I was shopping around for 33x12.5 tires and 8" wide rims I was told again that they would refuse to mount those unless it was a 10" wide rim minimum.

So am I to guess all the tire shops in my area are just being stupid or dont' want to deal with it?

 

When I wanted to get larger than stock tires (32s) the tire shop said they wouldn't fit. After I told them that there were several people who had successfully run this size tire they said that they couldn't mount them because the tire was outside of Toyota's specs. I pushed back making it clear that I was not going to buy a smaller tire and they said that they would do it but I had to sign a waiver.

The shops that you are looking at may have a similar waiver policy that they aren't telling you about. Try being more forceful.

 

Yea..........at the time it never occured to me that they may have some waiver I could sign. They basically had told me about the Toyota spec thing and that was that. I'll have to remember your advice for next time.

Thanx

 

the general rule of thumb for rim width is 3/4 of the section width-

IE: 12.0 X .75 = 9.0" rim

With that said, I use a 8" rim on 12.5 wide tires to help prevent poppin' a bead at reduced trail pressure. They work fine- although you might see a little faster center wear due to crowning of the tire.

later

 

i would say with that suspension setup you might into some problems running 33x12.50s. the 1st thing to consider is that due to the added width of the tire, you will rub on the upper control arm, if your rims have stock backspacing. the second problem you might run into is that if you have correct backspacing on your rims so the tires miss the A-arm, then you will run into problems rubbing on the fender wells. i personally dont know what backspacing would be perfect for this application, but i know i tried running 33x12.50s on my 98 with my SAWs cranked pretty high, and i still rubbed really bad. so its something to think about. if you can find a shop that will try the 33x12.50s for you and then exchange them if they dont fit, that will be key.
just my .02 tho

I agree with casey

You will rub with just the OME set up. You will need to get a 1 or 2 inche body lift from roger brown.
That will be my next mod.

Are your wheels stock Toyota issue? If they are they are more than likely 7" wide. I am running 11.5 x 32's on stock 15x7 alloys with no problems. I'm planning to make the jump to 15x8's for 33's when these 32's have had it.

Two reasons for using the 15x8 for this. The whole low air bead poppin' thing and in PA, there are strict wheel coverage laws. If the tires stick out more than something like a 1/2 inch or so, you give PA's finest a reason to harrass you. 15x8's with a 12.5" wide tire is the widest I can go and be legal with my Bushwacker flares.

 

btw there is a 33x11.5 out there, the only one i know of is the swamper thornbird, its the right size for you but probably not the right tire. thornbirds are loud and arent good on road, so youd assume theyd be great offroad, but tsls are much better.

 

They are not OEM wheels, they are exactly like this wheel, same model offset and everything:

Also, I plan on having a 1" cornfed spacer upfront to balance out the lift, so I think I'll have a little more room in the front wells than most. I think the rear tire will have plenty of space, especially since the most offroading this thing will ever see is a curb.

I'm really having problems finding tires, so any suggestions you have would be great. I heard somewhere that the 2wd models see a little more lift than the 4wd models, but I haven't found that to be entirely correct yet...

 

ttt cuz I need help!!!

btw - I have OME891 & N86 and OME882 & N91's

 

the only reason 2WDs get more lift is because they come about 1" lower than 4WD stock. but overall, they come out to be the same height assuming the lift components are equal.
on the other hand, it is easier to lift a 2WD higher because there are no CV joints to worry about. but if you go too high then ball joints and steering components begin to wear no matter 2 or 4WD. just some things to consider...

here is what i would do if i were you...
try and find a shop that will order you 33x12.50s, 33x10.50s and 32x11.50s, try them all, see what you like, see what fits and go from there. i really wanted 33x12.50s but just couldnt fit them so i settled for the 32x11.50s and i dont regret it at all, no matter what it will look cool, trust me

i have 33x12.5 tires mounted on my stock alloy rims, theyre only 7 wides and i have no problems at all as far as center wear or anything. The only trouble i had with them is balancing them was a bitch but now they ride perfect and have no problems whatsoever even at highway speeds

 

Ugh I can't figure out how to start a thread
