Solid Training Tire

This is a solid training tire that wears well. I have these on both Aluminum and carbon wheels and have noticed that the stiffer the wheel the more harsher the ride. Harsh is not the best term but they are not like a premium sew-up that has a latex tube where it feels like you are floating on a cloud. The ride stiffness is many due to the fact that this tire does not have a tube yet a thicker casing. On Aluminum the ride is smoother than clinchers. Both of my wheels are 23mm wide so I'm using the 2425mm tires. They provide a very nice profile. The tire are easy to mount after a night of stretching. Basically I mount a new tire on a rim and inflate it to 100psi then deflate the next day, then tape the wheel and remount the tire straighten and fully inflate let it sit a day then ride.

Great tire at a great price.

Nice tire. Make sure you pump it up dry mount for a few days before gluing and finl mounting. It is a tight stretch. Otherwise a very good tire. Round and well made.

On second pair. They inspire confidence when leaning the bicycle at high speed. 150psi at least or the rear will fell soft!

The price on the tufos made them a can't complain purchase. I glued them on to some older, but still really nice, straight spoke dura-ace carbon wheels using the 3 day method. Be carefull grabbing your rear calipers, if you slide it on concrete the compound will show threads quickly! I took them out to a super slick lowes parking lot to lean 'em hard on the glue before riding out on them. They feel great under load! I strongly recommend 150psi minimum. I ran mine up a little higher. fun to ride on and a cinch to install after a carefull stretch. They will not work with all brands of valve extenders!

Practical, resistant and good valeu

Tufo tubular clinchers sit on a class of its own. If you haven't tried them, you will either love them or hate them...

Installation is a challenge for the first timers, but once you get it, it's in fact much better and easier than a regular tire.

This is entry level Tufo T-C and I have had a couple and have had the most expensive ones as well. As for puncture resistance, I could never tell the difference and all in all nowadays I go with this cheaper one for training.

Love these tires!

I use these tires on my 1979 Trek 930. Great value because they are flat resistant as well as extremely nimble. The ride is second to none. Added bonus is using the Tufo Tire Sealant after small punctures.

Questionable Quality Control

What is the most catastrophic failure you can have with a bike tire while motoring along at full pace? You can have the valve blow out of the casing and send you skidding along metal to pavement in a split second. As unbelievable as that sounds, it happened to me on a brand new S33Pro (less than 100 miles). One might reasonably believe that youve got to strike something pretty big or pretty hard to cause the valve to completely separate from the tube and casing, but youd be wrong. There was no indication of compromise to the tread or sidewalls and the pavement surface was clean and free of debris.

Explanation? Its anyones guess but it does bring into question material quality and workmanship.

That said, Im buying a replacement and a spare. Dont take this as an endorsement, I simply think these tires are good value and the half dozen Ive ridden and worn out serviced me well.

The treadwear is also a bit disappointing, alas, thats the tradeoff for grippiness.

Good tire at the right price

At this price point I use the tire for training. Which is all I do. It holds up well (get the larger size).

I have six tires so far but have not gone through them all. So far, so good. Will post another review if any of them do not meet expectations, but so far this is the only tubular I need. Others just seem too expensive....good for racing, perhaps, but I am not racing!

Compared to the lower priced Thai tires these wear better and have fewer defects.

Disappointed performance

I was really looking forward to put this tires in my bike and the excitement lasted 7.5 miles this past weekend as I had to walk every mile back to my car as the tire literally exploded for no reasons. I did not bring a spare tire so I had to go 30 miles back home. I bought two of them and will be returning them.

Pretty good commuting tire if you must commute on tubulars

I purchased these Tufo Pro s33's in redblack at 24mm size from here, BikeTiresDirect, in June 2015. It was a super hot sale, nothing else comparable was cheaper. Anywhere.

Installing was easy, easier than other tubulars. I had a cheap set of clement futura tubs and those were a total finger busting nightmare compared to tufo's, even after stretching them for days. Anyway, my Tufo's mounted straight with no lumps.

Ride I've read somewhere that these tires ride as if one were riding on a garden hose. I'm not sure what PSI that comparison is applicable to, but I sort of see why, even on 24mm. I don't have a guage on my frame pump, but I find that they ride best if, with a strong effort, your thumb can press in on the top just a little. Any more pressure then the ride would be too rough for me.

Durability I have not punctured after 500mi over coarse road surfaces, and brand new road surfaces that have an inexplicable amount of unavoidable sharp pebbles and (sometimes) glass. I haven't even gotten around to putting any sealant in yet. Pebbles that stick in and go around countless revolutions are not a death knell to these tires. However, i do have a small gash on my rear tub- far right side tread, and there are slight marks where something might have stuck many miles ago. But, no damage to the side walls.

Overall, I'm very happy with these tires. I'll gladly consider the Tufo brand again, any model, the next time I buy tires.

Save your money! Just read, Unreliable

I left a review before. Biketiredirect guys were nice and sent me replacement tires. After 2000 miles total on 6 tires, here is the verdict about this tire. DO NOT BUY.

I used to pump to 130-140 PSI. First two tires got flat less than 500 miles which didn't seal with stan and pitstop. Third one got flat less than 200 miles, sealed but the next flat didn't seal. Trashed 3 so far. Replacement tires both front and rear got flat which sealed. Rear tire after 500 miles showed some worn spots and during a desend a chunk of rubber on the surface peeled off (almost 7 cm lenth). I made it home but the next tire again got flat under 300 miles. Sealed it with stans again. But in every single ride either front or rear tire sealant fails and pops out and I have to reseal, as a result I can not inflate more than 100 PSI to avoid seal failure. More than 105 It will pop in 10-20 miles.

For now I try to get more miles out of them by using sealant but honestly looking forward to buy other brand tubs and set these on fire one day.

Some comparison

Rolling slower than Clincher Conti 4000s, Vittoria slick, almost same as Vittoria pro

Grip Less than Clincher Conti 4000s, Vittoria slick, Tufo S3 lite tubular....scary if you don't watch the speed in cornering, no grip on little gravel

Me 167 lb, training to race. mostly train on clinchers, Tubular weekends, 200 miles weekly. Usually ride on good asfalt and never had so much problem with other tires on the same roads!!! And yes I watch the road to avoid glass and junk

THESE ARE AMAZING and Lightweight

I had continental hard shells before because I like my tires to last since I ride daily or as often as I can. But I gave these a try and I really enjoyed them there smooth and lightweight compared to other brands I used before as well. These ride smooth and have lasted me a long time no flats no problems I recently purchased more for some of my buddies that ride as well so they can try them out.

Trashed two, less than 500 miles!

I usually train on clincher tires so didn't ride on these tubs very often. My second training ride less than 200 miles, got flat ( 2mm cut), stans and vittoria pit stop didn't fix it. The other one same exact situation in less than 500 miles. Tires looked new when I trashed them. Seems like one small hole or cut opens up and leads to a larger cut parallel to the thread lines which can't be sealed by sealants. Result is flats anyways. So disappointing. Ride quality, weight and grip are not bad but these tires didn't last for me. Such a waste of money. Consider stan, pit stop and Co2 used and ended up calling for pick up. One word unreliable.

Great tire for training and racing

All top 10 finishes in races this year on this tire with 6 wins, 4th place in Connecticut TT Championships and 2nd place in New England TT Championships. No use telling me the tire don't perform. I've been getting good mileage out of these tires. Note I think the CS33 Pro is comparable for clincher rims.

So Far So Good

Only have about 500 miles on them so far but I love the ride. Tubulars are definitely smoother and more durable. They don't seem to have much wear on them yet, wouldn't expect them to this early in their life but I would definitely recommend these to anyone that rides Tubeless. And, to those of you who don't give them a try. At the price it's a great introduction to Tubulars.

Very nice tire.

The tire performs very well. Rode the previous set all summer. Probably got over 3000 miles out of the rear tire before something sharp found its way through the cord in the autumn. Over 10000 miles this year. Most of the miles were on Tufos. Every time I put my Vittoria pro on, I got a flat. Now it's a trainer tire!

quality, durable all purpose tire

have been rolling this tire for a couple of months now and couldn't be more pleased. it is a good quality tire that holds a 210 rider with no problem. doesn't lose air when racked in between rides and tread doesn't seem to wear to rapidly. ride this 40K a week this time of year, with some additional occasional roller training. definitely a buy again
