Well I finally got the extra cash (love work bonuses!) and replaced the seven year old tires. I was able to pick up two Dunlap d404 for 190 dollars. They wanted to charge me 50 bucks per tire for mount and balance with an additional 150 to take the wheels off the bike. My jaw about dropped, so I did it myself and saved the 200. Took roughly 2.5 hours total and the rubber is much more sticky and smooth riding compared to the old hard rubber. I ordered some balancing beads, however, when I took it for a ride I didn't notice any vibration all the way up to 70mph. My question is do motorcycle tires always need balancing?
