Stock ride height and stock wheels aired to 32 psi…. Had to trim some inner fender on passenger front ( rub at full turn and on incline/decline )….Love the look and compared to the OE Falken M/T, the ride is close. Falken was better overall, but it is 35s compared to 33s. C rated as well!!!!

How is the transmission handling the jump from 33 to 35 with the stock 4.10 diffs? Do you notice any issues with gear shifting at lower speeds or overdrive shifting on the highway?

Props to Toyo for finally giving us both the RT Trail and RT Pro in a C rated version in a true 35x12.50. That wasn't the case when they both were first released! Undoubtedly will choose one of the 2 when I get new tires this summer. I have a set of the RT Trails on my F150 and they have been awesome On and off road. 30k miles on them and they barely look worn at all, too.

so do you think they would’ve rubbed with a small lift or was it a turning issue?

Battling that right now...... Country roads around 55mph, the truck like to stay in 6th now... Interstate around 70mph, it likes to stay in 7th with the occasional visit to 8th. Something I am going to live with I guess. MPGs are down about 1-1.5 mpg..... Company gas card so who cares about that :)

Have you updated the tire size in the computer? I know when the tire size hasnt been updated it causes issues with shift points and whatnot. Tazer is a good solution for that. Both my JL and JT (Both with stock gearing and 35"s) shift like "stock" after updating the tire size in the computer.

I updated the tire size a couple of times... First time was 35 dead on.....A tad off (vs GPS). Then I backed it down to 34.75 (tire is 34.8 unmounted) and this seemed to bring the MPH close to dead on. Then I read about measuring the tire on the truck and it came out to 33.75. Adjusted to that and the MPH was 3 off of GPS (67=70). Put it back to 34.75 and waiting to test drive at lunch. Even at 34.75, highway travel was more in 7th than 8th, but country roads I saw 8th more than when it was set to 33.75.

Updated the JScan tire settings to 34.75...... I am now seeing 8th again!!!! Averaging 17.0 MPG on hwy and country roads. Just to tinker, I bumped my Banks Monster up a couple of clicks and that has made a difference as well.
