I had a few Blendmounts from other vehicles and pieced together one that works with my Escort and cam. It sits out from the windshield a little further than I’d like, but I like that it’s pretty close to the mirror. Only took about 10 mins to get the shrouds off, wires tapped and put back...
The Toyo AT III comes in a 295/75r 17 and is a C rated tire. It’s 34.4 tall … not sure I wanted to go quite that extra diameter, but I don’t really want an E rated tire. Odd that nearly all 295/70s are E sidewall tires.
