2005 Holiday Rambler Ambassador. What is the minimum dual spacing for this motorhome? The existing center to center measurement is 13" on the rear tires.

It's the tires that have a minimum spacing, not really the motorhome. The spacing is dependent on rim width and tire size.

Check your rims, the size will be stamped on them. With the 13" center to center, do the math on what your actual spacing is, then check with the tire mfg on what the spacing requirements are.

I just went through this when up sizing the tires on our MH. We went from 275/70-22.5s to 11R-22.5s. Much taller, same spacing requirements with our rims.


There are 24 hours in every day - it all depends on how you choose to use them.
