Attached are some pics of the new Venom X I mounted on the front of the '83VR a few months ago. I rode it lightly around town, and then about 750miles over a 4 day weekend at VWIII. I noticed a clunk when apply the front brake and while inspecting the caliper, play, and such, I ran into this on the side walls on the tire. I'd Venture to say there's about 1000miles on it since new. In Avon's defense the front tire pressure was about 10 pounds low when checked in Susanville, and I did ride it pretty hard while running up Hwy 395 after friday's group ride. Stopped for gas with Steve (hdhtr) and got a little carried away trying to catch up with the pack. My question is #1 can i expect this after running a tire low on pressure at high speeds.. 90+ in a couple of areas and #2 should I replace the tire or will it hold up?? I also noticed that on the sidewall the tire inflation should have been 50psi instead of the 40psi I thought was enuff. And should I just go ahead and bite the bullet and pick up a replacement?? Whatcha think???
