Question about tires!

[LongRanger_imp]

In addition to the size mismatch, consider that the Dunlop K505 is a bias-ply tire, not a radial (the 2013 CB1100 was shipped with radials). One proper fitting OE tire is the Bridgestone BT-54 radial, about $105 front and $145 rear, delivered to your door from various online retailers. Depending on how you use the bike, you may find these to be perfectly sufficient for all-around use and wearability.
