Anyone running +35 offset wheels with 285s? 275s?

[IcemanSTX]

Yep, that would be me - rears were still close but to be safe, I installed ReadyLIFT crash bars because I knew they would rub while off-road. That size of tire and lower offset is better suited to a 3” lift than my 2-1/2” level.

Jay @JACKSMYDOG has the right idea when it comes to his 285/70R17s - he lowered his offset enough to clear the knuckles, but kept it high enough and lifted his truck high enough to keep his tires out of his wheel well liners. And, he removed the crash bars just to be sure.

Thanks! At this point I have to assume clearance will be an issue and just accept that I will have to modify/ replace crash bars. Then with my only 2" front lift, make sure whatever I choose for tires clears the UCA. 275 might be really close. I think I'm gonna eliminate 285s from the choice for now. When my wheels come, I'm tempted to mount one tire and put it on (not drive, just check backspace clearance). ? I'm already trying to sell my first unused wheel setup

That image is perfect. From 265/60-18 to 285/70-17 the inner side wall will move 10 mm farther out from the suspension, and the outter sidewall will move 30mm farther out. I'm on 285/70-17 with +35 offset.

you think they’d have any clearance issues on a 275/70r17 with a 17x8+35 offset?

My truck was lifted and front bars removed before I took possession so I have no reference on factory set-ups. On mine, I only had slight rub on the right side rear crash bar, so I probably could have left the rears in if I had 275/70 not 285/70.

Hypotenuse is ~0.31" if I did the math correctly.

Anyone here running the +35 offset wheels with a 8.5" rim with a 12.5" wide tire? Just need to know if the tire will clear the calipers. I've removed the crash bars just want a 12.5" wide tire as close as possible to stock offset (mine is +54) while clearing the calipers.

Tires won't be an issue for calipers, they his suspension parts like UCA. Rim width isn't a factor for off-set.

Factory rim is +55 and 265 rubber (10.4 inches), which leaves about 5-7 mm clearance on the inside.

+35 rim, moves the inside sidewall 20mm away from the suspension, so now you have 25-27mm clearance.

12.5 tire is 53mm wider than factory (318 minus 265), centered on the tire, so 26.5mm closer to the suspension.

IMO that's a risky plan.

Also diameter above 32" at that width will be a factor.

Forget about rim width, it is completely irrelevant.

As an update, I finally got my wheels and tires. Went with Method 703, 17x8.5 +35 with 275 70R17 milestar Patagonia atr. I will post pics soon. But this clears all the crash bars for me. I have a 2" lift via Fox suspension. 285 would have hit the front bars for sure

That is the exact wheel I'm trying to buy, the exact same part number. I currently have the bronze one in a 16 0 offset. I just need to know if a 12.5" wide tire will fit on that wheel in respect to the calipers only.

Tires do not hit calipers.

Won't hit calipers, but not sure if that will clear the upper control arm.

Thanks for the input guys. Looks like I will stick with the 0 offset as 4.75" is the max backspacing with the bajakits LT kit.
The 0 offset wheel has a backspacing of 4.75" whereas the +35 offset wheel has a backspacing of 6.2"
My current 16" wheel has a backspacing of 4.5 so I might look for a 17" wheel with a little less backspacing than the max limit.
Looks like I did need to look at more than just clearing the calipers.
Thanks again.

Yah I didn't find much on here with people running even 285s with a plus 35 offset. I was worried if I ran a 285 (32.7" setup) I might not clear the UCA and I would hit the crash bars. I see now I could have cleared the UCA with a 285 easy, but definitely would have to lose the crash bars.

Superdannyboy, curious to why you where thinking of running the +35 offset wheels? I know the Baja kits says run a 4.75 backspacing but has any actually tried to put a high offset rim on with the Baja kits.

To me, I think the +35 offset should work. You have a longer lower control arm and longer upper arm. The uca and spindle are being pushed out the same, along with the brakes, rotors and all that. it’s not like the uca is protruding further than the spindle, or designed differently.
Have you tried mounting your stock wheels to the front to see if there is any clearance issues?

I’m running a 17x8.5 wheel +35 offset with 255/80/17. I get that the 285 is 30mm wider or a little more than half an inch either side but I think if I had the Baja kits LT kit the wheels and tires should still clear everything.

I'm running the same size tire on factory wheels, 2" lift.

Did the offset change put you into the crashbars? Just curious, I'd like to push the wheels out a bit, but also want to keep the bars.
