Ultra Wheels at Tire Rack

[-0-coach-0-]

Will this Ultra Wheel fit? https://www.ultrawheel.com/wheel/12...th-clear-coat/14623/3878/5/?sku=123-2905BK+18

The Tire Rack website lists it as one that will fit. But the size is not exact, and I don't know enough about wheel fitment. I have a buddy who gets Ultra Wheels at cost and would love to find some that would allow me to get a nice set of off-road wheels and tires versus my 22" Blacks

Its offset is 30 mm different so I’ll definitely move the wheel and tire outward. Same offset as the Dodge ram wheels.

Based on the offset and bolt pattern, looks good.

Most sites show compatibility based only on bolt pattern and don’t take into account other factors, like brake clearance and tire rubbing. Even if there is clearance for brakes, with an offset of only 18mm, you most likely will have tire rubbing at the lower ride heights. So just because you can mount them, doesn’t mean they will work well.

Looks like it shifts the outer position by 1.42", that is considerable...

Depends on if you want a 34" (Rivian OEM 20") or 33" (Rivian OEM 21/22") tire with these. The 33" tire would match your 22s and likely wouldn't rub, you might get some rubbing on the 34s.

And going with a narrower tread width could help too, but 1.4" seems like too much...it will also shift the inside position by almost an inch to the outside...away from center of gravity

Agreed. I'm actually disappointed in Tire Rack, as they generally have a solid reputation. They have done this at least 3x now on wheels that have compromises over OEM fitment. I would do as jjswan33 says, run a 33" tire if I were using these wheels.

Question, If I go with Type 52 Rims and 275 60 R20 tires these should be drop-ins for the 21's with no rubbing? the offset is same as factory correct?

 

[ksurfier]

Yep
