4.6 and 35's
 

I have a 1997 f 150 with 164,0000 miles. I have recently ordered some 35x12.50x17 pro comp mud terrains. I was wondering how well my truck will turn these tires on the interstate and in town. Im thinking it will be a little under powerd for these tires comments please

probably not very good. I'd get a set of 4.10s for sure.

what gear ratio do you have and what mods? i have the 4.2 v6 with 35's and had 3.08's for about a year and it was rediculously slow and then swapped the 3.08's for some 4.56's and it got SOME power back. My only mods were an intake and catback

I have 3:55's a cold air intake and true duel flowmaster super 40s

The true duels with 40's is honestly probably hurting your low end power!!! I used to have the same thing. I would go with 4.56 gears for 35's. It will be under powered for sure with 3.55 gears and the 4.6.

Ihave a 2000 f1 with a 4.6 with the exact tires you have. I'm running 4.88 gearing, mods include volant intake and a flowmaster 40 series dumped and I couldn't be happier with that set up.
