I got me them fancy racin' tires...

I went in on the group buy to get the awesome racing tires and the latex tubes and I am pumped to rock a more frictionless Kona. That said, I have about 4 more rides before I pack the bike, and a few of them will be on the trainer. Is it a bad idea to put these fancy go fast tires on the trainer for 2-3 hours...or is that a wicked bad idea?

Thanks!!!!

    I personally use my new race tires for at least a week or two before the first race that I will be using them. My reason is more that I want to make sure the tire is good and there are no defects or installation errors on my part. The general thoought on slowtwitch is rolling resistance generally gets better once the tire is broken in and has 100-200 miles on it. I haven't personally used race tires on the training but if you are only going to do it for 2-3 hours total I can't see it doing any harm. There is more of a chance of damaging them out the road.

    I've found the trainer flattens out the rounded tire profile in no time.  (And as science tells us, a flattened profile is significantly less fancy than a rounded profile). 

    I would build on Matt's point, and use these outdoors only, in the weeks leading up to the race.

    Assume 1 hour on trainer = 20 miles.

    Assume 1 trainer hour is 3 times the wear that road use is, so effectively 60 miles. (Seems pretty aggressive to me)

    3 hours on trainer = 180 miles. Unless there is really a special deshaping mojo that I can't figure out, you should be fine.

    The difference between trainer and flat road is that the angles are more acute because pressure is spread out less. This means the tire (depending on how much pressure you put on the contact) may be deformed more than when on flat ground. That can explain increased wear on them and premature flattening, but I still have trouble seeing how you will kill them in 2-3 hours.

    @William, you have obviously never seen me crush the trainer. image Looks like Monday is the only non-rain day this week, so I'll make it outside for an hour. Excited to go full race kit, wheels, etc. image Now I gotta shave these hairy legs!

    Ok, I guess I set myself up for that one!

    My trainer has much higher resistance than real world... I only go 75-80% of outdoor pace, so I was just making an assumption (same watts). I guess I just got the extra thick fluid. :-)

    You tires will be fine on the trainer. I have a set of those tires that I have had on my road bike all year. They have held up fine with trainer use. As Matt suggested you will likely make them roll a little better with more use before race day.

    Totally fine, P. I made it through all of last winter and half the summer on last year's set of Vittoria Open Corsa CXs.

    Thanks TEAM! Just getting those last minute "I suddenly don't know jack" pre-race vibes. image I rolled the new tires, the 808s and an aerohelmet on my local 28 mile loop yesterday. The middle loop was 20 watts below goal IM effort and I averaged 22.4 mph. Granted minimal winds, but man it felt awesome....c'mon TAPER.
