265/75 R15 - would these fit a stock JK? Would I need backspacing for these? I am thinking from what I have gathered that either 15x8 or 15x10.5 rims should work..

ok here's another way to do this

Would 265/75 R15s (31/10.5 R15) fit on 15x8" rims with 4.5" backspacing?? Stock JK with no lift...

Thanks!

Lots of good info here.... almost too much to absorb.. lol!

I was looking at some 16x8's for my 04 TJ and noticed that two of the rims I was looking at are pretty different as is comes to BS....

I plan on running 285/75/16's and maybe later to a comparable 35 ( 305/315)

my question on the BS.... Mamba MR1's are 16x8 with a 5" BS.... the other 16" wheel is listed at 3.75"... I know the less BS pushes the wheel outboard, but was concerned that the 5" BS is too much for the 285 or even a 305/315.

Am I worried about nothing? I read that 5" BS is the MAX... but the MAX is for what size tire?

I went through the same process with wanting 16" rims. I also found that most of the wheels didn't fit my needs as far as backspacing and bolt pattern, with those size tires, you'll be better off with back spacing of less than 4", mine are 3 5/8, my tires clear everything- spring mounts in the rear and tie rods/frame while making full turns, without sticking out too far. also the cost of the wheels is much more for 16x8 as compared to 15x8, and each tire on 16" wheels are $20 to $40 more than on a 15x8 in wheel. something to think about when times are tight and you have to replace tires.

I'm stickin with16's. I stood up 33's next to a 285 and the difference is over 1" in height. The BS is my only concern when it comes to rubbing with a 285 and then later with a 305/315.

Know that all tires are not of equal measurement, check the real dimensions at manufacture websites and tirerack is a good source too.

Ya I know... but I took BFG A/T's and did the lineup.... I couldn't believe the difference....

I know that the 285 is only a 33/11.50 and I had it next to a 33/12.50, but there is a big difference...

Rubicon 2012 Wheel size 17x7.5. Does anyone know the offset and spacing? Not planning on lifting. Need to buy second set of wheels for snow tires. Want to go with 17x8 or 17x9 but need to know the appropriate offset and spacing.

For winter I would go with 16 steelies. They are all over eBay and CL and cheap. I am running a KJ 16" wheel on my TJ with snows. The BS is supposed to be 5.5 inches. I would like to get spacers bc I have a slight rub on the LCA at full left lock and in the back if I go offroad at full ext I will have issues w/o spacing them out.

I'm trying to decide what rims to buy. One set is running 3.5'bs, and the other a 4'bs. If I run a 10.50 wide tire on the 4'bs rim, and later switch to a 12.50 wide tire, would I have any rubbing issues?

I can't decide on the mickey Thompson wheel if i should go with a 15x12 or any other 15xanthing what would be the best decision for going off road and on the beach but also on the road.

I don't think they'll fit easily. I don't know YJs, but I think the Rubicon tires are closer to a 32" tire.

Why didn't the wheel spacers work? Your other option is buying wheels with less backspacing.

You can fit a 33" tire on a stock JK.

You have an 01 TJ? I feel like you may have issues with 4" of backspacing and 12.50 wide tires, but I don't know for sure. I have just about 1/4" of clearance from my sway bars with 3.75" of bs.

How wide of a tire? Many run a 15x8 or a less popular 15x10. DEFINITELY don't get a 15x12! With a 15x8, they'll be lighter than a 15x10 and you'll be able to air down more when off road. A negative is that it is harder to get a good contact patch and some don't like the look of a 15x8.

Here is what my 15x8 wheels with 3.75" of backspacing looks like with a 33x12.50x15 tire

what about doing a 16x8 or even a 17x8 is there any difference with doing a bigger rim size

Not really. Just less side wall, more expensive wheels, and more expensive tires. You can't air down quite as much either.

Iv read so many definitions of backspacing from so many different people and I still dont quite understand it. From my understanding, backspacing is like the radius of the wheel? anyone wanna hold my hand through this question? haha

Not exactly haha. Okay so imagine a wheel. Now flip iit over so that the side that is supposed to be out is not facing the ground and you're looking at the back of the wheel now. Now imagine laying a straight edge across the surface of the wheel and measure from the middle of that straight edge down to the mounting surface where the lugs are. That measure from the mounting surface to the height of the lip is back spacing. The less back spacing there is, the more it will "stick out" when mounted.

Jerry has a picture that displays it pretty good but I can't find it.

Nope they're 3.75" bs so they fit fine.

And if you find a rim you like, but only the offset is listed (such as -12mm), and you wanna convert it to backspacing (in inches), here's a formula for doing the math:

Offset to Backspace conversion:

Take offset, divide by 25.4, then add the overall rim width (rim width +1) divided by 2

so: given a 16x8 with -27 mm offset, your backspace would be:


-27mm / 25.4 = -1.06" + (((8"+1")/2)= 4.5") = 3.43" BS

Make sense?

Advice needed, I have a 90 wrangler I just ordered a set of 33x12.5x15 Duratrac's. I now have 15x10 M/T classic II with a 4" b/s and the same size 33" BFG All Terrain's. I want to go to an 8" rim. Question is can I get away with a 4.5 b/s? For a more "tucked" look. I turned the wheels lock to lock an have around 5/8" between the tire and spring. Present tires have probably 1/2 tread left there just dry rotted. A PO put on in '89 or '99 according to tire date, (It's time).

Looks like I should have researched 1 more day before ordering tires. Seems to be more options in the 16's than the 15's. Lesson learned.

What is the best 35" rim/tire combo for my stock 2012 Rubicon? I would like to stay with at least 16" wheels or larger.
