No "morphing" here, my tires are 256/70/18 and always have been.

Ah, my mistake. I thought I was still talking to Paw Paw.
OK so, agood1, YOUR tires are either 275/70-18s or they're 256/70-18s?
If it's the former, they are 33.1" tires. If the latter, they are 32.1". That's an unloaded diameter of course. I would use a value of 2560mm if you have the bigger tires. If they're the ones you said you have in your last post though, try 2483mm.
In either case though, 2646mm sounds way too big (that's the larger tire with NO "squish" effect). You'd have to be driving a VERY light truck!
