Don’t always rely on the manufacturer’s advertised measurements; you’ll want to measure it yourself to get the most accurate measurements for the proper size truck rim.
You will need:
- Tape measure
- Paper and pencil to write the measurements down
- Diameter
- Width
- Offset
- Backspacing
Step 1. Diameter
Measure from the inside to inside of the bead seat. Do not measure from outer edge to outer edge. This is your diameter.
Step 2. Width
Measure from the inside of the rim bead flange to the opposite bead flange. This is your width.
Step 3. Offset
Offset is the distance between the rim centerline to the actual flat mounting surface where the rim comes contact with the hub.
Step 4. Backspacing
Set a straight edge level across the backside of the rim. Measure from the inside flat mounting surface to the outer lip of your wheels (to the straight edge). This is your backspace measurement.
Your site offers a wealth of information on vehicles of all kinds. Great site!
This post is straight and to the point. I like that. Especially since I am completely unfamiliar with the topic. I didn’t have to wade through an ocean of information to find how to measure rims.
Is the post aimed at people wanting new rims? Or is it also useful somehow when choosing tires? I’m assuming rims since I could just look at my tires to get info for tire replacement.
The diagrams are perfect. The only measurement that didn’t have a diagram was “backspacing”, and if you could provide readers with one it would be perfect, in my opinion. I cannot visualize what you are describing otherwise! Just don’t know enough about rims.
Good luck with your site! I think it’s going to do great.
Thank you for reading my post and for your great advice! Yep, it’s for customers wanting to learn how to measure their truck rims to purchase new ones in the same exact size. Or to see what size they currently have if they would like to go with bigger truck rims.
Great post!
Thank you! I hope it helped to clarify on on how to measure rims.
Cheers!
