How can I identify these wheels?
I just picked this car up a few weeks ago and the wheels came on it already. I know that they are Rohana RFX2's, but I have no idea what size, offset, etc.
Is the only way to determine that to measure the old fashioned way? |

Most wheel manufacturers stamp part a number and/or specs on the inside of the wheel.

I think he means the "inside", as take the tire off the wheel, and as all mine are, it is stamped on the rim under the tire and not the backside of the wheel. Good luck.

Sometimes the specs are stamped on the back side of spokes or the hub area. Hopefully that's the case for OP!

Yea that would be great for him if they are!! Save some time and money having to dismount and remount and balance 2 wheels.

If the specs aren't stamped on the back of the spokes or on the hub mounting surface (which means you don't have to dismount a tire), just measure the width with a rim width caliper. You can then measure the backspacing using a straight edge across the inside edge of the wheel and measuring down to the hub surface. If you know the width and backspacing, you can calculate the offset: 25.4 * (Backspace - (Rim's Tire Width + 1) / 2). Note that here you're using the nominal rim width, which is what the caliper should give you - not the actual edge-to-edge wheel width. That's why the "+1" is added.
