Tires and mounting "drive direction"
Tire gurus -
Saturday I was prepping for my next trip (all paved to Agua Caliente Springs) by taking the K270s off and putting the K761s on.
When I originally installed them, I set them both up so that the "drive" arrow was rotating forward - that is, the tires were mounted identically on the front and back.
While inspecting the front tire for wear and damage, I noticed a bit of cupping, which lead to a bit of thinking on my part. Perhaps a bad thing...
My bit of thinking went along the lines of "what does the drive arrow mean for the front tire?" I came to the conclusion that the front tire's driving forces happen under braking, and so maybe the drive arrow should be pointing the other way around from the way it is on the rear tire. In other words, the tires are now mounted asymmetrically. I don't know if it will have any corrective effect on the cupping.
Do any of you have experience with this?
I took an informal poll out in the parking lot. Bikes were a Buell Lightning, Ducati 848, Vulcan, Star, and Goldwing. Each bike had the same brand and model on the front and rear. Most were labeled "Front Only" and "Rear Only". In every case, the tread patterns were identical, but the tires were mounted asymmetrically. Also, when looking at the tread pattern from above, looking forward, the front tires always had a pattern that looked like a "Y" - grooves fanning out from the center, pointing forward. The rear, of course, was exactly opposite. Some of the tires had an arrow on the rear tire that said "Drive" and some had one that said "Rotation".

I still held his automatic more or less pointed at him, but he swung on me just the same. It caught me flush on the chin. It was meant to be a hard one, but a pansy has no iron in his bones, whatever he looks like.
'How' are words so important they cannot be too often used.
