towing 5th wheeler with lt245/75/16 tires

My current trailer is close to 13k lbs. Been running 265/75/16 tires for years.

That is the great thing with my TV, it came from the factory with the Optional Camper package 3500 springs, and 265/75-16 E tires, the bummer is it still has the same VIN sticker as the Non camper package unit 8,800 GVWR and 6,084 rear GAWR. :h It must have been too hard for Dodge to make a different VIN sticker. I still have close to 600# to get to the 6,084 of the VIN (max for the stock tires), in theory my rear axle could be rated at 6,830.

265's require a 7" wide wheel. That's what the 1 ton SRW wheels are. Fairly easy to find in the junkyards or on Craigslist If 265's give you enough capacity, that's what you need, 1 ton SRW wheels.

If you need more than 3400 lbs load per tire in a 16" wheel diameter, you need 285/75-16E's, which are rated 3750 lbs per tire.

I had custom heavy duty steel 16x8 wheels made that are rated 4000 lbs per wheel. I had to go custom because I could not find any 16" wheel available with a weight rating greater than 3500 lbs, back in 2007. I had them made by Stockton Wheel, in California.

Are any of you towing a 12,000 or heavier trailer using the GM stock wheels and 245/75/16 tires? Any problems related to these narrow rimmed tires?

I have an '02 D'max that I bought with 265's on it, and have continued to put them on since. I picked up about 900 lbs' tire capacity, which puts me just over the RAWR on my tires. I can live with it... :-)

245/75-16 have 3,042# capacity

265/75-16 have 3,415 capacity

This is a difference of 373# per tire for 746# extra capacity on the rear axle.

Hmmm, maybe that's why my BFG's kept separating. I'm pretty sure that their capacity was much closer to 3500. Oh, well...

They work just fine as long as you ensure that the OD will work for clearance between the trailer body and each other plus have the 3042 pound capacity. Yes, I had used them on an earlier 12K pound 5er for 4 years before trade.

I believe OP is referring to his tow vehicle tires. Stock GM rims will not fit a trailer.

As long as you're not overloading the tires, there shouldn't be a problem. Many millions of trucks have towed trailers with narrow 235/85-16 tires, which used to be the standard tire size for 3/4-ton and 1-ton trucks not too many years ago.
