what type of tire is faster

I have the folding tires and the tires that are not and are already in a circle. Which ones are faster? Reason I ask is which would be better in a race?

Re: what type of tire is faster
I suppose it depends on how heavy you are. I am a 220lb rider and can turn a set of tires in one season ~2200mi into drag slicks by the end of the season. I have been frustrated with low inflation rates due to my size and feel like I am just dragging. My local bike shop told me to avoid anything over 120psi, but they are wrong. I bought some Vredestein TriComp tires (https://shop.sunrisecyclery.com/item/12000/) and love them. Nice and hard, and very sticky. Check them out!

Re: what type of tire is faster
The rating on the actual tire is 175psi, I ran them this past weekend on 150psi and they were great.

Re: what type of tire is faster
I would go with two since every tire compound is different and I would not want to be hitting turns at high speeds and going down the side of a mountain with different compounds. I would think that you want the characteristics of the rubber to be same. Follow the link that I gave for the cheapest price that I have found. Plus, the shipping is free!

WHAT TYPE OF TYRE?

Tires vary by design. Folding tires are lighter and therefore the rotational weight is less and therefore faster. This is a key. If you want to ride faster without practice, lower your weight but focus on lowering the weight of anything that rotates on your bike. Tires, wheels, crank arms, pedals, shoes even, and so on.

I happen to love Vredesteins as well and the Tricomp has been a staple for me. I ride/race 9 to 11 thousand miles a year and always get good mileage on the Vred's. If you really want to buy speed, get a set of the Tricomp SL's. Only about 190 grams. I put them on race day and take them off after the race but they are easy to get on and off. They are lighter so I "feel" faster (and I am) but they don't wear as well as the tricomps. Plus the tricomps have varying materials for grip that are good for cornering for example. Get a 700 x 23 tire. While they are rated to 175 (though this may vary depending when made) DON'T go that high. The tire rims you have probably can't take it!

Mavic didn't even want to tell me how high I could go with them. I weigh 180 lbs. or so and race day I may go to 145 if the roads are smooth. Less if they are rough. Vred's actually ride better at the higher pressures. Some riders say that too high causes the tires to bump or bounce and as a result you lose road contact which slows you down but usually I keep the pressure up. (Mountain bikers know about putting too high pressure especially in the rear as the tire bounces too much.)

For you big guys out there, consider a 700 x 25 tire as well. Performance has a blue tri comp on sale often for about 25 bucks. Bike Tires Direct often has Vred's at very reasonable prices as many shops don't carry them but I'm addicted and even though I work at a shop I usually have to order them. Now, Vittoria makes some nice tires and others will swear by their Continentals or Michelins, I like the tire to look cool, perform great, and tolerate high pressures. For me, going to 125 lbs from 110 is like adding a free gear.

Re: what type of tire is faster
You sound like an extremely serious rider. I respect your opinion. Me, I am still learning. I have found my Vredstein's to work very well at 150 psi, not much hop and stay sticky in the corners. I have used Michelin tires before with the "pretty" colors in them but found the tread wear to be lacking.

Re: what type of tire is faster

I will on a very smooth road and during a race go to 150 and I do feel the advantage BUT I'm a little nervous about my rims holding up as I mentioned that when I called Mavic about going to 175 psi they wouldn't even respond to the question. I asked, "well, is 145 okay?" and they said, that would probably be okay but it was like pulling teeth. As there are different roads and rider weights they don't want to incur a liability saying it is okay if they hadn't tested it. It is up to the rim/wheel manufacturers and these are on my Ksyriums which are, in my mind, a particularly strong wheel!

This is a fun forum and useful to so many who are new to the sport.

Rotation

I forgot to mention that while tires rotate, I like to rotate my tires from front to back as you might with your car tires. I will usually swap them at seven to eight hundred miles. I may be kidding myself but I think this maximizes the duration of the tires. Most of my buddies and I agree that the rear wears at twice the rate of the front. One pal buys three tires and when the rear is worn he puts on a new one. When that is done he replaces both. I like to do it in sets if possible as I prefer to put two new and shiny tires on at the same time to spiff up the bike!

Re: what type of tire is faster

Looks like you found some good tires. I am a 200lb rider and I ride contintentals 4000 rated at 120psi but I ride 140psi in the rear and 130psi in the front. Just rememer to let out some pressure if you get caught in the rain and the roads get slick. Also there is a common practice of rotating front to back and back to front after about 500 miles or so. The rear tire wears faster and wears a flat patch in the center of the tire. Some racers like to put the rear to the front once that flat section has worn in, they say it really makes for better handleing.

Tell us what tire is working for you

Re: what type of tire is faster

Well, I like to rortate tires as I mentioned and will usually do so around 700 miles unless I've taken the tires off for some reason like putting a lighter tire on for race day. Anyway I don't think I get better handling though after I've taken that flattened rear and placed it in the front. In fact I notice diminished handling for a ride or two. I do it to maximize the mileage of the tires and that's about it.

Re: what type of tire is faster

There are two main factors that apply to tire speed: Weight and Rolling Resistance. For weight, lighter is simply better, but one must take into consideration that lighter tires are generally less durable (luss rubber to protect the tube inside, though many have built-in protective liners as well). For rolling resistance there are many factors that one must take into consideration: Compound, pressure, tread design, etc. I have heard there are websites that illustrate power required to turn different tires, but have yet to find it. Power is the most accurate way to measure if you are getting more speed for your effort. IF you have a power meter, you can experiment with various tires, pressures, etc. and determine which really is best for your bike set-up, weight, etc.

All things being equal, increased tire pressure will reduce rolling resistance, at the expense of grip (less contact area with the road). Additionally, with increased tire pressure on typical clincher rims, one must take into account the strength of the rim tape protecting the tube from the spokes, rim strength, and bead strength. When I was running clinchers (I now run tubulars), I found that Tufo tires allowed the greatest pressure without worring about the other rim factors. Tufo is a tubular tire with a special bead built onto the casing to hold it on a clincher rim. I typically ran them at 140 psi. for training, and on race day pushed up to 180 psi based on the road conditions and terrain. Remember that with heavy braking on down-hills you will generate heat in your wheel which will increase pressure.

Try a pair of Tufo Tubular Clinchers and you will probably never go back to your standard clincher tire!

Re: what type of tire is faster

Tofu's are excellent. Just make sure again, that your rims will tolerate high pressures. Also, cost comes into play. If you search various sites for tires there are good deals out there.
