I have a M931 with Goodyear 11.00-20 on it. I got 60 MPH during the recovery trip home. (based on GPS unit)
I was going to Super Single the truck with 14.00-20's to get more speed. After checking the spec's on the tires I do not think I will follow through with change. (not an upgrade)
The Michelin 14.00-20 and Goodyear 14.00-20 both have a maximum rated speed of 55 MPH.
The Michelin and Goodyear 11.00-20's are rated 68 MPH.
I was going to Upgrade to the 14.00-20 in order to gain MPH speed. I do not think it would be safe to exceed the Maximum rated speed of the tires! So I would actually lose speed instead of gaining it! (i can do 60 with what I have) Obviously the truck could go about 12% faster (67 MPH) but exceed the maximum rated speed by about 12 MPH.
I only found one tire that could be considered an upgrade for the M931 truck. It's the Goodyear MV/T 395/85R20 tire -which is rated 68 MPH according to the spec sheet. That would give a 7% increase in speed or 4 MPH. Since 64 MPH is under the 68 MPH maximum rated speed the tire would be safe to use as an upgrade for the 11.00 tire setup.
I am only discussing tire safety on Maximum Safe Vehicle Speed.
I would love some feedback on this topic.....![Git-r-done :grd: :grd:](https://www.steelsoldiers.com/images/smilies/grd.gif)
