Tire Change Mid-Trip
I am planning a May ride to the Southwest from Seattle and expect the ride to last 3 - 4 week and 5000 - 6000 miles. When I leave Seattle in early May, I estimate I will have about 3800 miles on the original tires, Bridgestone 152 Trailwings. Bike was purchased new in March 2013. Yeah, yeah, I know-- I need to get out more.
Tires look fine now -- lots of tread life left. I'm a conservative rider and pay attention to tire pressure, etc. Most of my riding is on pavement, with very limited gravel road travel.
My questions are: How many miles can I expect from these tires? Do they wear out evenly?
I think I should have a contingency plan for replacing these tires mid-trip if they show significant loss of tread. I don't do tire changes myself -- don't have the equipment, nor the inclination to learn how. But I don't want to limp into some cycle dealer on the road and pay his prices for both the tires and the installation.
Comments, suggestions and recommendations will be appreciated. Thanks.
