Rick, that was a 235 55 16 if i remember correctly, it lasted several miles, the only reason i took it off is because at one time i tought i had the bike sold and the potential buyer was a nay sayer
Probably the passenger benefited too. The CT dampens the ride. Also, you were probably rolling straight roads.
I have tried 225/55, 225/60 and have a 215/60 in order. I might try a 235/55 later. We can converse and take notes in MV then put something together for the CT riders and CT wana-bees in The Group. There are many, here in the USA in Europe, Australia and New Zealand.
Probably there are some Touring riders that have experimented with different size and aspect CTs.
