Race Tires for Aero Wheels(6 posts)

Race Tires for Aero Wheelsbimini

Got my new Shamals and now looking for what tires to put on them. I am 180lbs. Most of the road races for CAT 5 here are shorter than 50 miles so comfort is not a big deal.

I am going to move my Verdenstien TriComps over to them for the races this weekend, but I will be getting a set of race only tires to put on these race only wheels.

The Shamals are clincher and heavy so going super light does not make sense. I'm after low rolling resistance and a shape that will benifit the aerodynamics of the wheels. Don't care about life, just don't want flats during the race.

I have been very happy with the TriComps so they are a strong option. High Pressure, good cornering, nice feel and have gotten good life so far.

I like road racing the best so this is my primary concern. Also do ovals and a few TT. Hope to ride my first Crit this weekend. I know they make Crit specific tires so I may get a seperate set of tires for Crits.

Continental Supersonics?
Victoria ?
Your thoughts?

The best aerodynamics are going to come from tires that match the profile of the rims: 18-20mm tires. The problem is that you and I are both 180# and riding 18mm tires is an exercise in futility unless you like patching tubes.

I have some Hutchison Carbon comps on one pair of wheels, Avocet's Carbon Ks on my Cosmics, and Michelin HiLite Prestige tires on all the rest of my wheels. (all are 23c) I just got some Ritchey Pro tires, but haven't ridden them yet.

If you like the TriComps, keep running them.

For aero, tires should be slightly wider than rimsKerry Irons

This may still be too narrow for reliable performance at your weight, depending on rim width. Vreds have a reputation for low rolling resistance, but Conti, Michelin, Vittoria, etc. are all good tires. None of these tires will win or lose a race when compared to the others.
you sure about this?MShaw

From what I've read on the subject, tires wider than the rims reduce the aero benefits significantly.

www.analyticcycling.com is always a good place to check out performance data.

This has been widely reported in the literature. The tire being wider than the rim allows for a smoother disengagedment of the flowing air stream, like the tapering at the back of an airplane or submarine.

Tire pressure is very important here. I use Vreds on all my wheels except my tubulars. DONT pump them up to 140 pis unless the course for the race is suited for it. For small tight crits you should use like 100-115 MAX! Maybe 115 on rear but certainly not in front. I used to race my vreds at 130+ and it was a huge diffeence when I lowered the psi...huge in that cornering was much more confident and acceleration did not falter any. If you are doing a TT thats straight for the most part 135psi is good. But road races and crits LOWER it for your sake and everyone elses. You wont notice a difference and all the pro athletes I know use like 110-120 top psi on tubulars and clinchers unless its a TT.
