I just got some Kenda 784 Big Blocks mostly because they were not expensive and I have had good experiences with Kenda 270s but for the first 100 miles I was very disappointed with their performance and was thinking I had made a big mistake. The bike was unstable and the front end wandered around especially when cornering. After they scuffed in things improved but only a little and the bike was still handling badly. I realized the new rear tire was taller than the stock tire it replaced so I adjusted the rear sag down by reducing the spring preload 3 clicks (from 19 to 16) and that made all the difference. The bike now handles as good as ever and the tires work great on both paved and unpaved roads. The front tire gives good feedback and feels confident in corners and the tires do not make a lot of noise on the pavement. I'm really pleased at how this turned out and I really like how the tires perform now. Just a simple suspension adjustment made all the difference in how the tires work with the bike. I've only got about 300 miles on them right now and can't say how fast they will wear but I'll post more as the miles roll up.
