Sidecar pusher tires tend to wear fast. I've had pretty good service out of the stock D-401's at about 5,000 miles. I don't know if the D-402 touring tires would last any longer on my rig.
The classic auto radial would make sense only if it would surely last 12,000+ miles, but I'm "hearing" they may be of softer compound that wear faster. However, I sure would like the extra braking traction with more rubber on the road with a flat profile auto tire. I'm not yet convinced it's worth a test.
I haven't had a rig in 23 years, but this is a picture of my car tire (205/55-16 Michelin HydroEdge) taken with 40,000 miles on it with my Valkyrie.
