3.31 or 3.55

Blue Line Fab · Feb 2, 2015

Looking at new 15's. Any thoughts on gearing for a 35" tire, 3.31 or the 3.55?

It will be my new DD and it will be used for pulling my trailers.

3.55 unless there real light trailers.

Ditto... The 35s on their own would make me get the 3.55s

I've got a 13 with 3.55's and 35' Toyo's and wish I had a 4.10 at least while towing. Now I just traded for the the 13 from a 12 King Ranch dually with 4.30's. I guess I'm used to the 4.30's because at 65mph I'm pulling a little over 1600 rpms with the 13. Kind of laggy in my opinion. I may step down to 33's when these wear out.

3.55 it is!

My 15 has 3:55's and my stock tires are 34.5"(20" wheels)......, plenty of low end power.

My 12 on 3.31 on 35x12.50 handled towing heavy loads great

My 15 F350 with 3.31 and 35's will pull 23,000 no problem, just have to lock it out of 6th. It's obviously not as good as my 15 F450 with 4.30's but it will do it.
