My Class A Motorhomes steering is pulling to right. I had alignment but in specs. What is proper tire rotation for a motorhome? Trying to get a couple more years out of tires since less than 5 years old.

Thanks
Joe

Always pulling to the right? Only under braking? Only whilst accelerating?

I dragging brake maybe? After a drive (carefully) feel the temperature of the hubs (or use one of those IR thermometers, assuming you can find one to buy currently!) to check the temperature of each wheel and see if there is any *major* difference.

A TPMS will also show this (if it detects tyre temp).

(Note I found that the side radiator on my RV can make my left rear wheels run hotter, something to be aware of)

Rotate in a X pattern, take the 4 off the back and put on the front. OK, MH tires are not rotated. Would help if you filled in the info about which MH you have in your signature. Answering the questions above would help. Maybe someone put a steering stabilizer on that needs adjusting?

It could be a brake issue does it puller hard when your apply the brakes.
If you have a temp. gun check the front wheels to see if the one side is much hot then the other side.

If the tires are not wearing uneven on the fronts then most likely it is not a tire issue. I would focus on the brake system up front. Also how many miles do you have on the MH?

Don't know how old your RV is but it sounds like a problem with the brake line on that side or the caliper itself.

RV's tend to set a lot so changing the brake fluid every 4/5 years is a good preventive maintenance measure.

Do you have a safe-T-Plus (or similar device) installed that may simply be out of adjustment?

Since you didn't give us any specific information about your "Class A" no one can give you any intelligent answers.

I have a 2005 Tiffin Allegro Bus 38 DP Diesel Pusher. Actually it pulls to the right while normal driving and I need to hold pressure on steering wheel to compensate for the pull.. I have an after market Super Steer Bell Crank. I recently bought still working out bugs. Mechanic checked out and didn't see any issues with suspension and air brakes. Recommended tire & alignment shop and I had them check the alignment. Minor Adjustments on alignment and still pulls. Tire shop did recommend to rotate tires and/or replace tires if continue to pull. I was looking for proper tire rotation pattern just to make sure it's done right? The Toyo tires are 2017.

Try your own adjustments.
First, ask yourself what makes it want to steer to the right? Take it one step at a time. We know that it will try to steer to the side of the front tire that has a higher rolling resistance. So, test drive it AFTER you lower the air pressure on the left tire,...try 3 psi LESS. And, add 3 psi to the right tire.
Disclaimer: This is just an experiment, to find out more about the problem. Go back to your preferred air pressures as soon as you finish the experiment.

Easiest thing is swap the front tires from one side to the other... pulls to the left now? Next I would swap with 2 from the same side on the rear... will have to unmount.

Exactly! Easiest and cheapest way to find a cause of the pull.

Happy Glamping.

My guess is that it was due to the right tire having a higher rolling resistance than the left tire. I'm pretty sure Joe will let us know as soon as he finds out.

My rig pulled slightly like yours, even with brand new tires all around. And it had been to 2 different and competing alignment shops and both said alignment is good. So, I installed a Safe-T-Plus steering stabilizer, and adjusted it to take out the pull. The road crown still acts on the steering, but on flat roads it tracks straight with no help from me.

I'm curious , now that the rig is tracking straight , is the steering wheel still clocked correctly with top of steering wheel at 12 o'clock when driving ?
