3.55 Gears and 35" Toyos - Bad Idea?

I just picked up my 2010 F250 (Switched over from a 2008 Durmax) and LOVE it! I'm thinking about changing from stock tires to a 35" Toyo MT. Is this a bad idea with my 3.55 gear? I ran the same tire on my Duramax and lost mpg and when going up hill the truck would downshift.

Any help would be appreciated!

THANKS!

your going to notice it just like you did in the durra slap.

theres a 10inch difference in circumference between a 32 and a 35 inch tire.

thats going to change your 3.55 to more like 3.25s

What tire and rim combo did you have from the factory? Because the 275/65/20 that come factory are over 34". I didn't notice that big of a difference switching to the 285/65/20 (34.8"). Hope this helps.

I guess it would have helped to post that tidbit! Yes, I did get the 275/65/20. Thanks for the replies.

You'll have to put some pics up after you switch the tires. 35's look so much better than the 275. I have to find a good AT 35 for my next tire that can get some serious miles out of.

I went from the continetal 33s to toyo 35 ATs and went from 14.2 to 12.8 on avg. on the lie-o-meter. No problem on the down shifting though, but I have the 3.73s.

If you have the 275/65/20 the difference will be minimal. Your stock tire is already 34x11x20. I doubt you will notice excessive downshifting. Your mpg may suffer minimally, but not much.

I'm interested in this too. I have the factory 275/65/20's and 3.55's. I'd like to at least go 35's, maybe even 37 toyo's. I was afraid the 37's may just be too much for the 3.55's though. Anybody made these changes and did some towing afterwards for comparison??

I lost about 2.5 mpg's when I went to the 35 Toyo MT's. Still plenty of power though.
