Anyone have firsthand experience going from 22.5's to tall rubber tires?

This was something I had not considered, thank you. I'll definitely need to consider dealing with hook height differences. Raising every loaded trailer by a couple inches so I can get underneath would not be very fun. Might need to consider getting lifting ramps like what I see on some spotter trucks. Not movable ones, just long, solid frame extensions that angle down low enough that the truck can push under trailers dropped too low.

 

Something I just thought of. Load creep. If the tractor tires are higher than the trailer tires, should I expect the load to creep back if not secured with bars or straps? It will be on a permanent very slight incline - will the vibration be enough to shake the load down the incline? I doubt it, since most loads don't move much on even 6% grades, but I figure it might be worth asking to see if someone has seen this occur.

 

I'm on home time. Truck's in the shop for some routine maintenance and dealing with a few little things. I have never had a need to look for the rear end ratio. I drove the truck as an employee, and nothing changed when I bought it.

That said, knowing where to look for rear end ratio will be useful for when I buy a different truck though, Thanks!

 

Yes, the only reason I am considering going to larger tires it is that I almost never use 1st gear. If I put larger diameter tires on the truck, that will change, though I suspect I'll still be starting on flat ground in 2nd.

The electronic settings will also certainly change, requiring tire data to be entered into the computer so the engine will be better able to operate efficiently and report mileage related data correctly. That won't be an issue as much for a manual transmission than for an automated clutch transmission, but it will still be needed.

I am already running the truck a couple miles per hour faster than what Crete set it to run at when it was a company truck. Putting larger tires on the truck will allow me to add a bit of top end speed without pushing the engine into even higher RPMs.
