No. Hole in the middle of the tire will be 17", Your 15" rim will be 2" too small. You will have to stick with a R15 tire, or look to buy 17" rims for that tire size.

BTW - I'll be looking at new rims for my TJ soon. Eventually I would like to go to a 32" tire. Probably a GY MT/R w/kevlar in 32x11.5R15 - not a whole lot of choice in 32" tire size. I'll be sticking with 15" rims. Costs are generally much higher for 17" tires than similar size in 15". I think I'll go with 15x8 4BS 5x4.5BC rims. My Canyon rims with 5.5BS and 31" duratracs still rub a little at full lock, even with a 2" lift.

So i know I saw it somewhere in this thread but can't find out now that I'm in dire need....I have an 06 LJ and am keeping stock rims for the time being. I want to beef up my tires a lil, what is the most I can get away with? It's 30.5 now, would both 32 and 33 be ok?

31 x 10.5 x 15 is the biggest you'll fit without any mods. Even then, you might need spacers behind the steering stops. I didn't on my 04 LJ.

32's or 33's will require some type of lift, and probably spacers for the wheels.

Trying to get an opinion as I don't fully understand backspacing; I was planning on getting 15x10 rims w/ backspace of 3.625 backspacing and Goodyear silentarmor tires 31", 10.5" wide... would these work on a stock TJ? Or should I look into something else? I don't want it to look like a skateboard, so to speak.

You can't put a 10.5" tire on a 10" wheel. It won't hold a bead. You'd be better off with a 15x8 wheel and ~4" of backspacing

Gotcha! The other option is 15x8 with 3.75 backspacing

That'll work! The lower backspacing with push the tire out further though, but not too bad. And you'll be able to use that wheel with a 33x12.50 tire if/when you go larger.

05 sport tires

New member - need some advise. Currently have 30/9.5X15 on stock alloys. Would like to move up to 31/10.5X15 and NOT do any mods to vehicle. Does you see any problems?

Thanks for any advise and actual experience.

Will rub at full lock. Started to damage the inside side walls on my front tires. I needed to add 4 washers under each steering stop bolt. Of course this increases minimum steering radius. You could also get rub against rear coil spring mount pad that would cut into rear sidewall. Spacing there can be tight with 31s on stock rims. I ended up replacing my rims for less backspacing and got rid of the steering stop washers.

If you have your heart set on using the stock rims, you could also grab a set of spacers to give you a little more clearance.

When ever this question comes up I seem to forget the spacer option. But be aware that spacers are not legal in some states, and some shops won't tuoch the wheels (i.e., for a rotation) if there are spacers.

I haven't bought the wheels/tires yet and am now wondering, what is the largest I can run on 15x8 with 3 5/16 backspacing on the stock suspension / no lift kit?

Tires & Wheels 2000 TJ just purchased 2012 Tire Set will they fit.

Putting the cart before the Horse.
I have a 2000 TJ Sahara, in need of tires. (Stock 30/9.5/15), I purchased a set of 2012 Take off's 255/70R/18 . I went on line and purchased a set of hub adaptors 5x4.5 to 5x5 1.25 inch offset. I haven't started the install of the new tires, but wanted to know if my new (31" diameter) Rubber will clear without needing a lift kit. I was able to get 5 brand new tires and 18" rims for less than the price of 4 tires mounted on my Old 15" rims. Seems like a lot of buyers of New Jeeps are doing tire and wheel package modifications, and the result is that a LOT of OEM tires and rims are available at really great prices. I had my choice of 255/75R/17 or 255/70R/18 same overall size (31").
If I need to do a lift, what is the least aggressive way to go.[IMG]/Users/Steve/Pictures/iPhoto Library/Originals/2012/Feb 18, 2012/DSC06652.JPG[/IMG]

I'm a Newb to the forum, but have been driving Jeeps for the past 40 years.
Here is what I just did, and it might interest you. Along with my Question.

Recommendations?

Just put 33x10.5 BFG M/T's on 15x8 stock rims and they rub slightly at full stop. This is the subject of another thread I started in the TJ forum, but also looking to see what folks here would recommend for wheel backspace and offset. This is a confusing subject...

We've considered a body lift on top of the 2.5" RC suspension lift. The debate over wheels alone vs. wheels, body lift and new rear bumper (for the spare) is ultimately about $$$... of course, we'd like all-of-the-above...

Thanks!

If you have too much backspacing, the tire is positioned too far into the wheel well and its inside sidewall can rub. Insufficient backspacing and the wheel protrudes out too far and can look like a skate board.

The bolt pattern required for a TJ is 5x4.5" and there's no real benefit to 16" except for the minor fact that the current style is for bigger wheels. But you'll find a larger assortment of Jeep type (offroad) tires for 15" wheels than you will for 16" and they'll be cheaper too. If you offroad and air your tires down, I advise a 15x8 wheel for any size tire up to 37x12.50, I'd only go for a 15x10 wheel if the tire was 13" or wider.

Here's how the backspacing is actually measured...
In the above example of insufficient backspacing, would that put excessive strain on the hub?

Here is my question...I want to get new wheels for my '06 TJ since it is tire time also.

I plan to run 31" x 10.5" x 15" tires. What wheel configuration should I order in offset and backspacing?

Thanks.
that small of a tire run a 4.5" backspace wheel 15x8 for general use. for max float on soft stuff and highway stability, longer tire life look at a 9" like the interco birddog wheel.
for rocks and stuff a 15x7 with a 4". tires? any good alterrian will work for a daily driver. goodyear duratrac is a "tweener" tire that gives a lot more versatility in wet stuff and general trail use.

Jerry is right on. the idea is to get it just right. not too far in or out. ideal is to have the tires kiss the front sway bar in a hard turn and max compression on the front and kiss the inside finderwell at max deflection on the rear. TJ's work well with a 4.5" back up to 32" the interco birddog wheel would work good for that. 33/1250r15 choose 4.5" or move to 3.5" if your playing in really high off camber areas interco birddogs offer both offsets

I was looking for some help I want to put some 305r70 17 tires on my 06 Tj, and I want to put them on a 17x9 wheel with 4.5 backspace and -12mm offset, I was wondering if the rim has enough backspacing and offset for that size of tire if I have a 3" suspension lift as well. thanks.

I just purchased some Irok 36x13.5R16. I have two questions:

What backspacing should I have on a 10" wheel?

Also being the tire will be a trail only tire(running low psi), would I be able to run a 8" wheel? Any negatives?

Thanks!

I'm on the other end of the spectrum here. I have 33x12.50x15 tires on 12.50x15 wheels, no idea on the backspacing. I like the 12.50 tires but I am concerned about the wheels being so wide both for the sake of the hub and ball joints as well as the wheel itself since it sticks out so far. Also as I learned in this thread, airing down could be an issue as well.

To keep the same size tires, should I get 15x8 wheels? Any real advantage/disadvantage to keeping the current wheels?

9" wheels

Can you put a 9" wheel on a stock tj. The wheel I want is a 17x9 with a -12 mm offset. I was wanting to go with 265/75/17 tires. A tire website says it won't work because rim is too wide and offset it out a reccomended specs. Is there a solution??
