Hi BigToe,

My oem tires were overloaded on the driver's rear side. Axle rating was not.

I chose to replace the wheels and moved to LT215/85R16 from Toyo. This corrected the overload situation.

This gave me a little more clearance.

It is extremely important to have the correct wheel size to width. A spacer is possible but....not as reliable (read possible not quite as safe).

Wider tires would not have fit on the rear duals.
