So I have the same RV, 2008 Freedom Express 21QB. I *just* had two new fronts put on by Discount Tire for about $200 a tire. That's mounted, balanced and road hazard.
I went with BF Goodrich Commercial TA All Season 2 - currently showing up as $142 a tire.
If you're trying to buy just *one* - then think before you do. Check the date codes, look for crackinh and replace both even if there's tread left.
One of the things I noticed is that when I called repair centers that if I used the word "RV", I'd get "We don't service RVs". Once I told 'em that it was just a big Chevy Dually Van, I could get farther.
For the simple stuff? Walmart here changed the oil.
I need an alignment and am still calling around to find a place that can do it.
