Okay, so I have been pricing out some 38's. The last guy I talked to said I don't want 38" bais ply super swampers under a suburban.... there is 35's under there right now. Is this true? I really like the idea of having better offroad performance, and they are on avg. $180.00 (canadian) cheaper then the radials. Cheap, and perform like a bat out of hell I like that. Is it just because of the sheer mass of the suburban I should stick to radials?? Or is this guy smoking crack?
