Um, no.
We took delivery of our Montana in September. Following March (yes, 6 months) and over a winter too, we were somewhere in Tennessee on our way to South Carolina in March when this happened. We were at a disadvantage finding another tire store, so had to use the spare. We were able to find a semi-truck / tractor-trailer tire shop that does nothing but semi-trucks near Fort Mill, SC (South and West of Charlotte, NC) and we got 4 semi-truck trailer tires that has about an inch of tread. An oh yes, they cost a pretty penny.
