tire wear

Hey everyone. I had a ural sidecar mounted to my Honda vtx. The sidecar supplier sent the wrong mounting hardware and no instructions but had machined and fit a vtx front wheel. I had it shipped to a bike builder in Palm Beach who had no experience with sidecars but is a genius and did a fine job of lowering the sidecar and fabricating the needed mounting hardware. A couple thousand miles on and my sidecar tire has a very worn flat spot across the middle, slight cupping on the bike side of the front tire kinda like a weird rounding patern?. The bike is pulling very slightly to the right so I am looking for someone in the Central Florida area to adjust everything so my ride is safe and stop it from burning through tires to quick. I have not been able to contact "Ural of Tampa Bay"? Also, a lot of vtx riders are switching to car tires for the rear of their bikes, anyone have anything to say about this in regards to doing it on a sidecar unit??

Thanks,

Geoff.
