10 inch or 8 inch Rims

[MotioncontrolMike [OP]]

I was told that it was better to put 33 inch tires on 10 inch rims instead of 8(or 7.5) inch rims. Reason being is that the 33 inch tire can curl up under the rim easier if it is a 10 inch rim when airing down to traverse snow pack or sand.

Is this something everyone agrees with? Buy 10 inch rims instead of 8 inch when planning to go off road typically?

Side-Note: I could see how the 10 inch rim would give a cooler profile to the tire on the FJ...but then would the 8 inch rim be better for a daily driver?

Any thoughts?

Many thanks

Tire width should determine wheel width, not height.

What size tire are you trying to run?

I ran 285/70/17 (~33) on stock 7.5" wheel and had no issues what-so-ever. Discount Tire will no longer put a bigger tire than that on a 7.5" wheel. To go wider, you need an 8 or larger.

This.

I am running 33 inch tires...the point the guy was making to me...it seemed...was that a wider rim with the same tire size would give better 'cupping' when off roading when aired down...true?

For example...33 inch tire on a 7.5 inch rim vs a 33 inch tire on a 10 inch rim....one better than other for off roading when aired down?

Like I said you are quoting tire height "33inches" but are asking about rim width. A 33inch tall tire can just as easily be 9 inches wide as it can 12 inches wide. Obviously if you want to run a 9 inch wide tire the 8 inch wide rim would be better, likewise if you want to run the 12 inch wide tire you're going to need the 10 inch wide rim. But you're not telling us what width tire you want to use, you only keep telling us the height "33s".

We need more info in order to properly help you.

Sorry about that...I get it now. I am a little slow...Want to run a 9 inch wide tire... so i guess the 8 inch rim would be just fine(not a 10 inch wide rim tho).

thanks guys! I really REALLY appreciate the expertise on this forum. I am indebted to so many of you.

Is anyone on here running a 10" wheel? That is a wide wheel. I have 9" wheels, and you can run up to a 13.50" tire on mine. I believe 10" is for 14" tire and up, which means its probably close to 40" tall! Correct?

Yup for a 9inch wide tire I'd pick the 8inch rim too. It nice to have a little meat on the sides


@weavinfj - OC maybe??, he's running 305s or 315s or something hella wide

Run with the 8" rims. Especially if going with a narrow tire as others pointed out. You'll have issues mounting a narrow tire on a 10" wide rim.
