Hi guys I am needing new tires for my jeep, I have never bought tires before and just wanted to make sure that these wheels will fit the tires. both are 15 inch but Im not sure how the width of the rim compares to the width of the tire. 15x8 15x7? Im sort of confused. Thanks

These wheels have 4 inch backspacing but my current stock ones have 5 (I believe). 2003 rubicon. Will this cause any problems? ( I have stock brakes)

with less backspacing they will sick out a little further and what size tires are you going to buy? I think most people get 15x8 that is what i have with 31's and plan on putting 33's on them when it time to buy tires

I would think a 15x8 would be better, check tirerack.com on the site it'll tell you the wheel width range the tire you want will fit on.
Also unrelated. Is that a reliant robin as your avatar?

15x8 will be good when airing down for wheeling, why not go with 33x12.5? Just asking.

Ah I thought so, those things are in the UK what jeeps are to us haha.

Only reason I went with the 10.5 becaseu I like the look of thinner tires. Someone also said that the gas mpg might be a slightly better. is there any truth to that?

(right now ive got the 12.5s

If its looked at in weight wise, they're 6lbs heavier each with the 12.5 so an extra 24lbs, but from what I've read(and its not experience so don't take me 100%) is that it's the diameter of the tire that accounts for the gas mileage, so whether you turn a 33x10.5 or a 33x12.5 the mpg should be the same, but again it's my take on reading multiple posts on the forums. And mathematically it makes sense.

I run 32x10.5 because they are 32.1" tall while 33" tires were only 32.7" tall. At least that's what my Super Swamper TSL specs were. Saved about $20 per tire and didn't lose much height. Recommended wheel width was 7"minimum I believe.

I think the 10.5 tire would look better on the 7" wheel and the 12.5 looks better on an 8" wheel.

just my opinion but i dont care for 33 10.5 just the simple fact they are almost the same price as the 12.5 and they look to narrow for the height. Not trying to make anyone mad my cousin has 33 10.5 and his jeep looks pretty good just not preferred size

Installed yesterday 33 x 10.5 x 15 on my tj

Backspacing is an issue - 3.75-4.25 I believe is what you want. I had centerlines on it with 5 inch backspacing and 31's and you couldn't turn without it rubbing.

If you are starting over do not use spacers just my opinion. Someone told me when I comes to jeeps save up and do it once just how you want it the right way. :)

Looks great! I think the 10.5s are awesome

So this is the wheel I want
cragar soft 8
15x7 4.0 backspacing

and this is the Tire I want
BFGoodrich AllTerrain ta ko
33x10.5 x 15


first off they should match up correct?
tires cost $1,018 for 5
and for wheels $312

so 1330 does that sound bout right for what im getting I havent ever bought tires of this kind

(Im planning on selling my moab rubicon wheels / tires(with like no tread) on craigslist to recoop a bit of it)
