Wednesday I increased the tire pressures to 36F and 40R and did not think that change would have any ill effects.
Tonight I decided to do the 35 mile section of the river road. To get there I ride maybe four miles of freeway. The frontend felt light so I shook handlebars and it wobbled noticeably. After I got off the freeway I added one turn or 1mm to the MotoWizard Preload Adjusters and that settled the frontend down. Soon I was on the river road and the tires were handling well other than a few moments. I cross a few grated bridges and the bridge in Walnut Grove does not like KLRs and especially does not like the T63 rear tire. I would rather ride deep gravel. The other issue this tire has is parallel (same direction) uneven road surfaces. The T63 does not like having pressure on the side of the tread. The tire will ride the rut.
I was looking forward to Death Valley but I don't think I am going to make it...but maybe.
Mileage is my main concern with the T63 is mileage. I will need to get 3,500 miles or 6,??? miles. These are my current options on tire replacement.
