Determining Rear GAWR
I was reading another post and it got me wondering... I have a 2013 2500 HD with a rear GAWR of 6200 lbs. I have 265/70R18E Michelin's with a max load of 3525@80 psi per tire giving me a tire load cap...

Legal you get 500 lbs per inch width of tire to 20K lbs per axel, ASSUMING, you have enough paid for license registration.....so a 265 width tire is about 10.5" or 5250 per tire, for a total of 10,500 per axel......
Warranty and performance factors, ie engineers ratings or what ever is a whole nuther ball of wax.
The end is what the spec needs to be, how long something is to last etc. The tire OP has, is good to 3700 lbs at speeds up to around 70 mph. If he is to stay below 25mph, you would find the tire manufacture would rate the tire at about 4500-5000 lbs. Doing nothing else to the tire.
Reality is, in this case as noted, the engineer difference is the spring pack!
