They want $575 per tire plus $120 per tire to mount and balance. CW wont put ... I know this has probably been answered, but can I safely replace the Michelin 235R8022.5 with a Toyo 255R70-225, M122. They cost $300 per tire. Thank you. 2007 Damon Outlaw.

yes absolutely. $120 is robbery. A shop with a machine can do it for $30.
Or even a roadside guy can change them with hand tools.

Toyo is a good tire and BETTER than the garbage michelins! Make sure you get the longer valve stems!

That is what I did the tire size 235R8022.5 I believe you can only get in michelin so I changed and bought 245/75R22.5 M154 toyo tires. The circumference of the tires were very close and the speedometer was only about 1 mile different.

As long as the new tire has the same or higher capacity without being too oversize and "kissing" on the rear without requiring more pressure than the wheel can take it should be OK.

It is going to be slightly smaller in diameter making more RPM/mile and the width is wider. Make sure your dealer will take them off if you run into clearance problems. https://tiresize.com/comparison/

Oh, avoid Camping World. Your RV and your wallet will thank you.

I have a set of Toyo M154’s going on tomorrow along with new valve stems (Dually Stems by Borg) and Centramatic balancers.

Another Newbie question, I am buying tires next week for a new-to-me Class A. How do you check the inside rear tire pressure?
I asked about an extension, the answer was that extenders frequently cause air leaks and not recommended.
Do you crawl under the coach to check the air pressure?
Thank you.

Jerrilynn; Inner dual is accessed for pressure check and adding air with a special gauge and air chuck .

The shop is correct about extensions causing leaks , B-in-L when through 3 different brands of extensions before he gave up on them . Takes a little more time and you have to get your hands dirty ; but knowing the tires aren't loosing air is worth it. JMHO, of course.

Thank you for your reply. Where did you purchase the special gauge and air chuck?
Thanks

For whatever it's worth, I've had extensions on my inside dual's now for 18 years without any air leaks.

I would recommend steel braided extensions.

Good luck and safe travels....

Canadian Tire , Princess Auto if you're in Canada . Harbor Freight in USA.

Do a Google search for " truck tire gauge " and / or " truck tire inflator " you'll find there's a lot to look at .

Not sure what type youre using but mine dont leak at all. They attach to the valve stems and are airtight.

You want a dual-foot tire gage that will handle the maximum pressure of your tires. One that goes to 150 pounds will be fine. Any decent auto parts store will have several to choose from.

If your tires are mounted correctly and with the proper valve stems you will not have any problems.

Just paid $750 for a Michelin tag tire w/ balance beads and a couple replacement chrome caps while on a trip two weeks ago. Didn't have much choice at 8pm to 3AM when it was done. Just glad they had one.
