silverbird1100 Posted January 18, 2005 Share Posted January 18, 2005 I recently e-mailed Dunlop about how altitude plays a role in tire pressure. He said for every 1000ft, 1 psi can be affected. Conditions will obviously vary but I've always wondered why one guy can get a tire to last for 11,000 and the other bike is showing the threads at 4500. Say you were to set your pressure at 6000ft, then ride down to Vegas or into the Sacramento valley, your 5-6 psi low in very hots temps and usually at very high sustained speeds. D220's make me wet for the first 2000miles but I wonder if looking after the pressures under specific circumstances would make them last longer? Also, this is not just about Dunlop's, but all tires.

rickrad Posted January 18, 2005 Share Posted January 18, 2005 Did they say anything about premature cupping? Quote Link to comment Share on other sites More sharing options...
bartonmd Posted January 18, 2005 Share Posted January 18, 2005 a BUNCH of it depends on how much power you plant through it too... I did just 5-6 full throttle runs up to 100 when I did the jetting on my 'bird and looked at the tire right before I left and right after I got back and there was a spot getting flat when I got back that there wasn't when I left.

silverbird1100 Posted January 18, 2005 Author Share Posted January 18, 2005 I didn't ask about cupping but if it comes from the tire flexing more than it should under load then I'd say yes. Quote Link to comment Share on other sites More sharing options...
demon Posted January 18, 2005 Share Posted January 18, 2005 Tread design or lack thereof has a lot to do with the tire wear. The latest trend in rear tires has a 1" wide treadless center that dosn't flex as much as a cross treaded tire. Quote Link to comment Share on other sites More sharing options...
AlphaBird Posted January 23, 2005 Share Posted January 23, 2005 I,m lucky if I get 1K out of a set of tires---Maybe this will help Quote Link to comment Share on other sites More sharing options...
