Is anybody changing the rear tyre soon? Trying a 170/60 may be nice

[Lumpy]

I'm running a 170 on the backand with a hugger. No problems with fitting and in my opinion the bike handles better

as I run a 1 tooth bigger front sprocket, a new chain of standard length, and new tyre (160 -023) means it rubbed until I mover the hugger forwards. As it is the bobbles rub on the new tyre just fitted. No biggy and not rocket science to sort.
