10 mm isn't much, that will be 5 mm per side. I usually run a 240, and tell everyone it's a 250. They don't know any different.
I'm runni9ng a Shinko on the front now, and it's wearing good. My last rear was a Shinko, they are soft and hold the road good, but when I went to BB&BBQ, it was about half gone, and the 6 hours I spent on interstate on the way home, it wore it flat in the center.[/QUOTE
When I got home, I found that my rear Avon has worn flat on the center also. I'll have to go with the 240 Shinko then and see how that will hold up.
