If you like an accurate speedometer, you'll need to change the gear... maybe. I think most of them now are computerized so you need a shop to reset it.
There are programs that tell a person what their speed is with different tires so I am ok with it.
Or a GPS.
Or just reprogram the computer so you can use the speedometer as intended. Keeps the odometer accurate too.
Personally with 35s I would be looking at new gears, probably 4.10 at minimum, which is where I think gearing should actually start in all trucks and a reprogram. Just what I have come to prefer if going with larger tires.
If more than a 5 speed auto I wouldn't have an issue with 4.33 or lower as long as you aren't going to be at too high of RPM at say 80sh MPH.
