I have been searching the forums for a couple of weeks now. I did not really get a good answer, but with so many variables I did not expect it. I do, however, have some more experience on my present tires and if my observations make sense, maybe I can get some recommendations to think about? I ride SOMO mostly (Javelina, Mormon, National), also T100, Hawes, McDowell Mts. I am 150 lbs, I ride a Iron Horse Hollowpoint MK 3 with DW-Link that I like. Recently wore out Weirwolf tires, 2.35. I am running Weirwolfs, new ones, 2.1 size, and I have them at F/R 25psi/29psi, tubes. Now I am washing out constantly, front tire squirms, took off some skin on a curve that I would never have fallen on before. I am riding more aggressively now, but not at all racing level. Is it the new Weirwolfs, or the size change that may be causing my problems? They do not feel at all secure any more like the old ones. I want uphill traction, I am not very concerned about speed, but my speed on Desert Classic and McDowell Mt is causing me to gain scars. I don't do real DH, but I do like the downhills on Mormon and National, but I don't drop more than 1-2'. Help??
