Is it ok to put a 160/60-17 on the rear?? What sort of difference does it make?

I've a 160/60 17 on my bike and has make no noticable differences on the turning of the bike.

A mate ran a 160 on the rear of his NC35 race bike and it was rubbing on the chain. He had to go back to a 150. I'd look into this before you go ahead and buy one.

ive always used 160's and never had a problem, might depend on tyre brand, some maybe slightly wider.

for reference ive used BT090's, Supercorsas and rennsports
