I bought new tires for my 1981 KZ 550 (Dunlop 404's). It has the original tires on it and is in need of new rubber. bought a set of Dunlop 404's but am concerned that I may not have gotten the right size. I haven't found a good size conversion chart to make sure. Here's what I got: Old New 3.25 X 19 100/90 X 19 3.75 X 18 110/90 X 18 Can someone confirm that this conversion is correct? I looked at the front tire, and the new on looks wider. I'm planning on taking it in on Wednesday (tomorrow) since it's actually gonna be in the 60's here in NE. Quick responses would be greatly appreciated!
