Tracy-- Get rid of those Rainer tires ASAP! Those tires are not rated for your unit. Go with a G rated tire such as Goodyear G614 or the equivalent in the Sailun brand. If you are going to be on the road the E rated tire is not enough for your unit. If you do a search here on the Forum for tires you will find a lot of posts on this very subject and the comments on what to buy and why. Since you will be traveling-- think about joining us up in Goshen, IN for the MOC Fall Rally in September. You can find out how to register and details here under the 2019 American Fall Rally section on the main page of the Forum. Welcome aboard, enjoy that Montana and hope to see you in Goshen in September!
P.S. If you decide to join us in Goshen, you better hurry and register for the Rally. There is a limit of 200 units for the Rally and we already have 194 signed up!
