I’m curious what is the tire of choice for forum members here. I have Michelin Pro Race tires on my current wheels, but recently purchased a set of “race wheels.” I was thinking of transferring those Pro Race tires to the “race wheels”, and purchasing another set of tires that are not so “nice” for my current wheels (i.e. a cheaper tire that presumably makes me work harder during training rides) . Alternatively, should I use Pro Race tires on both my training and race wheels?
I would put new tires on the race wheels…
I didn’t realize the Michelin made a tubular Pro Race. 
Seriously though, don’t put used tires on your race wheels… uh, I mean the wheels you are going to race on. Get new tires for your new wheels, either more Pro Races if you like them, or some Conti Supersonics or other ‘race’ clincher.
I would say the current tires have about 150 miles on them, that’s why I was thinking of transferring them. However, now I"m curious how often tires should be replaced?!
