Tires

Yet again another Tire question.

Currently installed Michelin 255/R70 22.5

Switching to Toyos, not certain which size yet.

Will Toyo M144 fit in the wheel wells without rubbing yet still provide a safe distance space for the duals?

Been researching and cannot find a definitive answer.

Thank You,

Do they make a 144 in that size? If so it will fit.

Edit: They do not. Looks like a M122. What were the stock size on a 2000 Exec?

Not sure what size you are wanting to go to. There really aren't any sizes I can think of that are close to that one in a 22.5 rim.

The stock size on my coach is 295 75 22.5. Are you sure that is the correct tire size called out on the placard by your driver seat?

Checking the Monaco Brochure for a 2000 Exec*, the OEM tire size is 295/75R/22.5.

The 255/70s you have are way lower in load capacity and their smaller radius may have been affecting Speedo and ODO readings. Using the Toyo tire book as an example, their M122 in 255/70R22.5 have a Max of 5510#/5070# @ 120psi (Single/Dual) while the OEM 295/75 size rating is 6175#/5675# @ 120psi. The Toyo book shows M144 in 295/80R22.5 size at 7830#/6940#; the book does not show a 295/75 size for the M144.

While different tire brands may vary, you now have tires with substantially lower max capacity. Unless some suspension-clearance modification has been made to your coach, the 295/75R22.5 tires should fit and restore you to the OEM carrying capacity. If you want to go to 295/80R22.5 tires, you can check the size vs the OEM 295/75R22.5 to see if clearance may be an issue there.
