I sent an email to Michelin and asked the same question on which of the was best for motorhome
This is what they told me....
According to your email you are interested in both the XRV and the XZE for your motorhome and would like to know the differences in the 2 tires. Both tires are acceptable for your motorhome but the XRV would be the recommended replacement tire for your motorhome. This tire is built specifically for motorhomes. The characteristics that I am listing below make this a very desirable tire for motorhomes
- See through grooves promote drainage efficiency to help combat hydroplaning and improve wet traction
- Multi-siping helps deliver better grip and longer, more even wear -shallow, stable tread generates lower heat and is built for greater durability, and reduced squirm
- improved handling
-Cool-running tread compound designed to improve durability
- increased ozone resistance in sidewalls helps provide excellent weathering resistance
The XZE was designed for commercial application and the XRV was designed specifically for motorhomes because they are not driven as much as commercial vehicles.
Hope that helps
