Thanks but, that’s not a track tire, it’s a bias ply tire. I have seen a few 130 size rear tires on EBAY, but they all were bias ply tires. I have ridden on some nice twisties with the Michelin RS 140 rear and pushed semi hard and the rear stuck like glue. I will most likely be riding the 250 coaching in the beginners group. At that pace I am sure I won’t have any issues. Going with the 4 inch 300 rear rim is cheaper than buying a brand new tire since the RS rear has maybe 100 miles.
