315's and 3.55 gears?

Looking to get new tires for my truck soon, wanted to get an opinion on running 315/75R16 tires. I currently run 285/75R16 tires and they work well. I am a bit concerned about my towing capabilities as I do tow up to 10,000 pounds behind my truck and sometimes a 7,000 pound travel trailer (I sometimes go wheeling and to the beach as well). What is y'all's thoughts, stay with what I got or is up sizing okay?

Is it an Auto or a Manual truck?

I run the 315/75/R16 BFG All Terrains with 4.10 gears and an automatic transmission and I love it!
I have heard people who run the 3.55 with 35" tires it can be lugged down when towing heavy weight.

It also depends on what sort of power upgrades you have done. If you create enough power then I wouldn't be worried about being lugged down.

I wouldn't do it. Mine had 305's with 3.55's when I bought it and towing is not real good if its fairly stock. If its been upgraded much, you'll be smoking more yet until your rpm's get up. It's just not a good combination to tow 10k. 265's would be better for you, but I sure wouldn't go taller than the 285's. JMO of course.

NO, you will hate it.

I tow exclusively with my truck and it is 4.10 and 315s. I could not even begin to imagine towing with 3.55s

If the truck is an auto with out mods to motor or tranny do not do it, you'll regret it.. I had an automatic 97 cclb w 35's and 3.55s and it hated towing, great unloaded on the highway but absolutely the worst combo for towing.. Like 427 said 265s would be the best for your setup... If if you have a stick you might able to get away w 33s but even at that you'd still be pretty tall...

Well my truck is an auto, it has a stage 2 rebuild from Marshall engines. I have a tw chip, 6637 intake and a 3"dp to 4" exhaust. I suspect y'all are right and I prolly will just stick to 285's till I can do a front axel swap and 4.10 gears.

Since we are on the topic of 35's, I have been trying to find a 35x10.50 for a long time...the only one I think out there is an INterco SSR and no way in hell will that work. Anybody able to find anything close? Currently on 285's and would like to go up a size, I simply don't want a 12.50.

I dont know any off the top of my head, they def are not that common. A 35x10.50 is a tall skinny tire. i know when they start getting taller there also designed wider to spread that much volume and load on more surface area esp with us being 3/4 ton and bigger.
