Depending on what you haul and your tire specs,rpms,size etc...there is tons of info listed here. Can also post a question to the Dr if you choose.
Bridgestone Commercial Truck Tires

Different manufacturers/models of tires in any given size will have different revs per mile.

Revs per mile is the fuel economy issue, as it changes gearing. Check the websites and your tire dealer for the choices available to you.

Really?! If you had read my original post, you'd have seen we were talking about my STEER TIRES. They have nothing to do with gearing, unless of course you have an all-wheel drive (10x10) truck.

not too smart, I am?

I let myself get distracted up there somewhere.

Carry on.

I've been looking at the GoodYear G372A 11R24.5 which spins 471 times per mile. With 3.73 rears this would put me at 1,282 RPM at 60 MPH or 1,400 at 65.5 MPH. I know a lot of flatbed guys here use tall rubber... Question: how badly will this affect my steering if I lose the low profile tires and put on the 11R24.5? The sticker on the side of my truck cab says, "Your tire is 295/75R22.5".

I'm afraid the switch might screw up all the angles in the steering again. When I bought the truck it had 11R22.5 tires and steering considerably improved after I switched back to the "factory size" of 295/75R22.5s...

The bulk of your op IS about drive tires.

Your truck have 10 axle ( x ) and all of them are pulling ?? 10 (axle) x 10 ( pulling) ???

I don't know why you'd bring up this old thread and pick on Tracer, who hasn't posted since last year. I'm sure you understood where he was going with that, even though using 10 x 10 was incorrect. But you're wrong too. If there was a 10 x 10 it would be a 5 axle. A 4 x 4 pickup is a 2 axle truck. A regular tandem tractor with both rear drives is a 6 x 4.
