Goodyear Marathon is the way to go!!! Smooth, quiet, reasonably priced, and tough as nails. A blow out can tear up your wheel wells, plumbing etc….so do not screw around with tires. ALSO..in my other posts..check the date on the tire!!! Camping world has tires on sale at crazy low prices..they will be 10 years old. warehoused so they can sell as new but they are junk.
