Wheel rim dimensions

Wheel rim dimensions

Wheel rim dimensions

(OP)
What is the outer diameter dimension for each size rim?  For example, it appears from random measurements that the OD is 1" larger than size (i.e., 15" OD for a 14" wheel, 16" for a 15" wheel).  I do not have a copy of T&RA's specs, but somewhat expensive to answer this question.
Thanks.

RE: Wheel rim dimensions

Rim diameter and width is measured at the bead seats.  The rim flanges stick up above this and have a larger diameter than the rim width.

RE: Wheel rim dimensions

Integrity,

The answer to your question will depend on what style rim it is (car, truck, spare, etc).  If you are inquiring about a wheel you physically have, then examine the brake/mounting side (inside or rear) of the wheel for any identification markings & post them here.  If you are designing a wheel, you should probably know the required rim type for the wheel's application before going any further.

Random measurements are not a good practice to follow because T&RA allows for tolerances that can vary as much as 2mm.  No, that's not a lot for folks who work in english units, but it could cause any number of problems.  Let's say you measure a wheel that is made at the high side of the spec. limit & then don't account for YOUR tolerancing, you may well end up with a rim that doesn't comply to T&RA standards...and depending on the business you are in, that could end up as a legal issue should you have any sort of performance issues come up.  If you're making consumer products, it would be my opinion that you obtain a T&RA manual, find out the rim type you are desiring & go from there.  Better to be safe than sorry.

I think the manual is $50 per year in the U.S. & is usually available in Feb. for each new year.
