Wheel/Tire loads

[Walker]

What's the physics (or math) on wheel and tire load ratings?



If you have a tire rated at 3000lbs, and a wheel rated at only 2000 lbs. what's the actual load on the (under) rated wheel that would make it unsafe for our trucks?



I'm looking at a set of black spoke wheels but they are rated less than what most are running.



How's this work?

Hi Walker... I don't know what the Gross Vehicle Weight Rating is on your truck, but it has to be close to 6000 LBS. . I am sure that you will recieve some great replys about your rims !!

I think that I would want as much rim strenght as I could get on my rig. Good looking won't be of much help if your sliding into a curb with the right front wheel and 3 tons behind it.

Ther are a couple of great tire sites which will be happy to give you some very qualified answers to your concerns. http://www.1010tires.com or go to http://www.google.com and enter wheels, automotive, You are sure to come up with a ton of information.

You are only as good as your weakest link, ... err rim! If you have a 2000lb. rated rim it doesn't matter how much over 2000lbs. the tire is rated for, you still have a 2000lb. max. rating for the tire/rim combo.

Search for a thread something like 'Steel wheels' in the offroad forum. There was some good info in that one.



2k lb Daytona-style rims won't cut it for long on these trucks unless you run empty all the time. The 3k lb tire won't keep the rim from developing stress cracks at the lug holes or coming out of round. The best bet for steel rims is contacting some of these rockcrawling companies that sell steel beadlock wheels to the jeep crowd. Many of them manufacture the wheel as well and you can order them without the beadlock. I've been debating going this route, but none I've found so far actually pay to have their wheels tested, load rated, and DOT certified. They get by under 'for off road use only' language, but I believe several of them are making wheels that exceed the tire ratings.
