Triangle Tires??

I really had to laugh when I read your title "Triangle Tires". When I ordered our Arctic Fox 5'vr from Northwood MFG--I asked them what kind of tires came with the camper--the Rep said "Triangle", my immediate response was "Nope, I want round tires"---my sense of humor was not appreciated. When we got the camper it did have Triangle tires on it--I swapped them out for Goodyear Wranglers LT. I couldn't give away the Triangle tires--even my pool cleaner and gardner wouldn't take them. Eventually, I gave them to the Salvation Army. Have about 25,000 miles on the Goodyear Wranglers with no problems. Lars
