Who can talk to me about bias tires? Looking to put a set of STA Superlug 900r16 (36"x10"x16"? on Charlotte, the International crew cab.
Citi driving with occasional highway but not concerned with going fast.

Personally I wouldn't do it. Bias tires will wander more and if your older posts are any indication they may cause you to chase down handling characteristics that are just a result of 1960's suspension coupled with old tire tech. I've had bias on my cruiser before and they weren't terrible but that is because the suspension on the 80's are great. But when I went to radials it made a huge difference. Bias are great for an off-roading rig though.
If you are just doing it for the look they do make bias looking radial tires.
Bias tech never really changed that much, tires from the 30's that Capone was riding on are pretty much the same design as tires from the 60's that muscle cars raced stop light to stop light on. While radial tech changes by leaps and bounds every decade.
All in all you should be good though if you aren't really driving the thing much and don't mind them following all the lines and ruts in the road more than radials do. Also flat spots after not driving for a while until the tires warm up.
