mutliple question

hey guys working on rebuilding my 95 f250 460 4x4 auto(e4od i think) and had a few question since im at the part where these parts will affect the truck. background info if helps is that i just bought a detroit truetrac diff for rear, front leaf is 4100lbs rating and rear is 3100lbs rating with also a 3 inch body lift that came with the truck already installed.

1. i was thinking about 35x12.50 tires on 17x9 -19mm wheels and was wondering if that would fit good
2. if i could run 35 inch tires would 3.73 or 4.10 gears be good. truck would be doing light pulling ex. 2 axle trailer with car or truck on trailer and maybe a fifth wheel camper down the road. ( additional info is that im putting on long tube headers, cam and MAYBE a bigger throttle body not for sure if that last one would help.)

thank you in advance.

With 35s you should probably stick with the 4.10, especially if you're to be towing with those tires on.

I wouldn't even think about anything higher than 4.10 with 35's.

I just learned this recently. Large tires also cause frame cracking from the steering box. Right at that steering box cross member. Just a caution. If you do, don't turn while at an idle. Always be moving when you turn.

ok another quick question is if i don't stick with the 35 and maybe go to a 33, would you guys still recommend a 4.10 gear?

Yes, if your towing. 33s and a 4.10 are alright. I get 15-17mpg with that combo. 3.73 if your just towing ba small camper. May struggle going up hill though at highway speed.
