Thanks in advance for any light you can shine on this topic.
You can go with 275/80R22.5 LRG. Some of us have already done that to help an over-weight problem on later model 390's. The bigger tires SHOULD fit your aluminum rims with no problems.
You should also consider the fit in the wheel wells, and finally your speedometer/odometer/computer will need to be re-programmed.
I'm NOT a FR or FL rep. Only way to know for sure if you need bigger tires would be to weigh the coach.
