I have looked around but found nothing comparable to the Bridgestone 850 and 851 for the tires. I have found that my Yamaha dealer in Columbia, SC sells them at inflated prices ($250 as opposed to $140 at the Tire Rack for the rear) and will not mount any I order, so i get the Victory dealer to mount them. The Yamaha dealer says they are afraid of being sued for a faulty tire they did not sell, but I don't see how. I have also gotten the Harley mechanic nearby to mount the front tire after i took it off the bike at home. He says he does not have metric tools but did a great job on the mounting. So tires have been my big issue with my Roadliner. Since i purchased the bike in 06, i see other brands producing similar sizes but stick to the Bridgestone and keep them pumped up for good cornering manners.
