They are only 1" larger in diameter than 235 80/16 tires so should fit those too if you have the clearance for them. You just need to INSURE your rims will handle the 110 PSI pressure. Both are also rated for 75 MPH. I will still limit myself to 65 MPH because it is easier letting the rest of the traffic pass me and I get much better fuel mileage at 65 than at 75 even when not towing my camper
Both are actually less expensive than the Maxxis 8008s I purchased last time.
I have dealt with these people in the past and they are SUPER to deal with!
My next tires will be one of these sets. Personally I like the idea of free roadside assistance.
