What kind of top speed is everyone getting with 53” tires on an M818?

My speedo reads 5+mph under with my 53s and coincidentally, I took a pic today when I was flat out.

Thanks. That’s what I was hoping for. I bought one today that has the 53” tires but the guy said he hasn’t taken it any where to see what top speed is.

It'll get up to speed, just not in a hurry.

The M818 speedo is calibrated for 11.00's. It'll read much lower than the 939A2.

OK, I'll be that guy and throw out the "53s are only rated to sustained speed of 55 mph" warning. How that's interpreted for a 10 ton tire on a 5 ton truck is a can of worms that's been chewed on in several other threads.
On the main topic, I've heard that the math says 72 mph at redline

That M809 series is looking so TUFF! I would be interested to know your turbo setup. If you have a post about it, if you would send me a link that would be cool of you.
On my M813 I am only doing 55 since that is the highest speed the tire is rated for. I have caught myself hitting 58 a few times but without a turbo on my NHC250 my truck is needless to say GUTLESS. Not sure if everyone else's is the same but definitively not spunky. My tires are the Michelin XZL version. There are some other manufacturers out there that also make a 16.00R20 like Goodyear and Pirelli if I'm not mistaken that may have higher speed ratings.

The Goodyear AT3A is also rated at 55

I don’t care about speed ratings. I’m not going to be driving long distance at high load.
