My 2002QD RIALTA has 16" Vanco 8ply tires,rated @106 mph And I haven't had any problems,They are rated 8200lb And the Rialta scales 7025lb loaded with me (300lb)in it....I see that Michelin has a 16" tire 26" in diameter ,looks like it will fit, And it's rated @3200lb per tire...If this would work, load rating would be 6400lb rear 3600lb front,,,total GVW 10000lb....I hope someone try's them
