I'm running a 2.4 MK SS up front and a 2.25 NN in the rear. The MK is a bigger tire, but not by much. I like the NN as a rear, not so much in the front.
I have a MK SS 2.4 mounted on a 28mm (outside) rim - the calipers say the tread width is 2.35" and casing width is 2.15".ziscwg said:Nobby nic 2.25 is really a 2.1. MK is really a 2.2. However the MK 2.4 is a little taller.........
