Best Tire wheel / tire size for towing. HELP!

I have the OEM 20" Ford wheels and just purchased yesterday some new Toyo AT II's in 295/65/20 which are 35.1" tall. I love the look of the tires, very (bad !$*&#) but I tow alot and there very squirmy while towing and has noticeable reduction in acceleration. Its my fault as I didn't research size enough and would have never went larger if I would have known. Anyway, great tire but just not for me. So I going to try and return them per the warrenty there running now "like um or return um" and thinking of getting the same tire in the oem size of 275/65/20 (34" tall). As I said i like them so am thinking of staying with the same tire just smaller size. Also, I see the OEM size comes in the standard tread height / pattern (not XT) which should help as well. My question is do you guys like this tire or would you go another route?

Lastly, I know most everyone loves the 20" wheels but for towing I will not buy 20's again on my next new truck. 18's with a 33-33.5" tall tire just seems better to me for towing etc.

I will agree that 35's will slow the truck down some. I went with the suggestions that I read. Most people will say that a 4" lift on 35's is the biggest you want to go if you still plan to use a bed-mounted hitch and still use the truck as a truck. I went this route and am very happy with the setup. 4.5" Rough Country lift on 35x12.5x18 Toyo M/T's. Anything bigger than 35's I'd highly recommend re-gearing. As far as 20's go I think a truck that's run mostly on the street looks good with them, but as far as an off-road or lifted truck I'm an 18's kind of guy.

I would recommend the BFG Rugged Terrain T/A or BFG T/A KO (if you want something a little more aggressive looking). If you're dropping to an 18 inch wheel, 275/70R18E is what came stock. That's a 33 inch tall tire +/- . 285/65R18E will give you roughly the same height with a little more width.

Tire and size choices are limited for 18 and 20 inch tires. If you can snag a set of 17 inch wheels (2005+) your tire choices increase dramatically.

ok thanks guys now just hope theres no loop hole in returning the tires tomorrow. I feel bad but I just can't handle this for 3 plus years till they wear out. Long distance driving while towing will be a pain with these shoes.

Ok,,, you went 1" larger and your whining,,, the 6.4's must really suck?
I went from stock 31's 265/70/16 to 315/75/16's i.e. 35's in my 7.3 and haven't looked back yet. I have 3.73's also and towed a 11,000# Rage'n Toyhauler with no issues whatsoever,,, If stock you had 34's and went to 35's and are having "a noticeable reduction in acceleration" you are way to sensitive man. ALL of my trucks have larger than stock tires, and the only one I really notice it in is my 79 with a 300/NP435 and 4.10's and I went to 33's, and that is with a load of wet oak.
YES, new tires are squirmy, get about 3-5k miles on them and all is good, but changing for 1" of difference,,, not so much.

Stick with the Toyo AT2s!

I upgraded my 2011 F350 SRW 4x4 tires from Conti 275/70R18 to new TOYO AT II 285/75R18. That is a jump from 33.4 to 34.8 in diameter. I tow a heavy 5th wheel or 11'6 pickup truck camper mostly freeway. The squirm disappears in the first 500 miles as the release agent from the tire mold dissipates.

I jumped from 3460 to 4080 max tire load at 80 psi so more payload headroom and have a comfy unloaded ride at 65 psi. Very little sidewall flex when towing heavy. My 6.7 lost less than 1 mpg in unloaded stop and go driving and remains unchanged in freeway driving. I don't notice any loss of power on the low-end and my cruising rpms have dropped a little so not a bad tradeoff for a highway hauler that no longer gets stuck in wet grass, snow on grass, grass, etc.

PS: I also upgraded spare and installed an extra exhaust shield so I dont cook the larger spare. All good.

this is a bit old but wanted to post back. I was able to return the tires as Toyo kept their promise. Again they are great tires for local driving and do awesome in the mud etc off road. Just not the best for towing and long distance driving. Went back to the Cooper AT2's and they are great at the type driving I do. Very quiet, smooth and do well off road too.
