Could not find much info on these tires for my 08 ultra. Dealer had them on sale this winter for 25% off + 15% of labor for a winter special. Got to finally go for a ride this afternoon. Rode about 200 miles today on back roads, two lane highway and around town concrete and black top. The tires seem very good. Comfortable ride, stable and no handling surprises. How far they will go before they wear out will have to be seen. I will know in the fall I run 10k to 12k a summer.
