Will 33x12.50 18 tires fit on stock rims?

[movingman619sd]

I have a 2020 1500 and i want to know if my 33x12.50 18 tires will fit on the stock 18 inch rims that are on my truck? I have a 3 level kit on front?

stock rim won't fit 12.50. you'll rub UCA.
you need minimum of -12mm offset or 4.5" backspacing for your wheels

Or they could fit just buy 1 1/2” spacer or 2” spacer (hub centric of course).

they could but i don't recommend spacers.
simply put, more things that need care (that no regular people would do themselves) and more potential failure points

Are the 18s different than the 20s when it comes to fitting 12.50s? I have 35x12.50s on my factory 20s and there is no rubbing anywhere.

I didn't use a spacer, just the Bilstein's to level the front.

offset could be different but I don't know for sure
I only do smallest wheel size possible and fit big tires for optimal and proper offroad use

I know I’m a little behind on this post but I had a similar question but with 11.5 inch tires in metric size of course. Would the 11.5 clear the upper control arms or would they also rub the UCA?

With the stock 18 inch wheels.

theoretically you should be fine since you're .5" shorter on the UCA side.
best approach would still be -12mm offset/ 4.5" backspaced wheels.

Thanks for the advice. I appreciate it.

Oh. They'll fit on the rims just fine, to answer your question.
Whether that mounted wheel/tire combo will fit on your Ram without mods is another question you should ask.

The width is your problem with stock offset wheels.

If you want to be 33" tall but don't have a width requirement (and IMHO why would you unless you are a serious rock crawler or mud bogger... but then 33's?), might I suggest a 275/70/18, which is guaranteed to fit 100% stock, offers a much wider tire selection, and weighs less than a 11.5" or 12.5 wide?

I am currently using 33x12.50r20. My local tire dealer suggested me to get -18 to -25 offset to avoid the uca and with beefier look. Anything above -25 will sacrifice your ride at high speed
