426 Vapor Tire Size

Hey Guys,

I just finished the install of my new Trailtech Vapor and I wanted to run my tire size by you guys. I have it set at 2070 mm, I used the marks on the floor method for measurement and came up with 81.5 inches. Does this sound right to you guys? Overall, I found the install to be pretty straight forward and easily completed it at a loafing pace in 2 hours from start to finish. Thanks for any input.


Looks good! I used the same method for the endurance and sunday at 58mph the endurance and the GPS were within 1mph of each other.

Great, I will have to check mine against the GPS on a flat run. I hadn't thought of that. Thanks,
