It's new tire time and I don't know if another 33" LT tire is a good idea. Hankook Dynapro ATM LT285/75/16 E is available for $718 installed but they weigh 59 pounds each! To compare, a stock p275/70/16 Michelin M/S weighs 39pounds. The discount tire guy said the oil companies put the dynapro on their field trucks which I find reassuring.
I have LTX MS/2 LT285/75/16 (33", 52pounds each) coming from flat places like AZ, TX, FL. I keep them around 42-45psi. Now I am in Colorado and I think the extra tire weight is really straining the vehicle over the i70 11,000 foot mountain passes. The truck will dip to ~2200RPM at 45MPH before I jam the pedal into the floor and it goes to 3-4000RPM and slowly regaining speed. I worry that I'm going to blow something driving like that. If I don't jam the gas it doesn't downshift.
I did have one day where I drove like a bat out of Hell from Denver to Junction and basically kept the RPM over 3000 on all the passes and it seemed okay but I was praying the entire time.
I mostly drive on the street. Have a medium OME 2-3"lift. I go to bike trails, ski areas and generally want to safely explore most of Colorado (don't want to blow out a passanger tire in the woods).
So do you fellows have the same experience with the RPM's and speeds on the mountain passes? Keep the RPM above 3000? Stick with 32" tires? Will 59# 33" tires be a nightmare on i70?
Thanks
