Well......I don't think I ever intended to do this, but with an upcoming tire change I will have tried three different tire sizes and tires on my 08 Custom. When I bought it in April 2011 it still had the factory 80/90-21 and I rode with that until April of this year when it needed to be replaced. At this point I wanted to change sizes to the 90/90-21 to stop the front end from chasing cracks as well as add traction as I ride a lot of dirt roads, so I went with the Metzler Tourance. I noticed an improvement in the front end not chasing cracks, but no real traction improvement. Fast forward to today and the Tourance is at the end of its life and I needed another option especially when I burned through a $150 tire in 6 months. Luckily I happen to troll a local auction companies website and was able to purchase a Dunlop Elite 3 120/70-21 for $55. So, then plan is to swap out the new tire within the next few weeks and I'll be able to compare all three for those interested.
