Tires for Reynolds DV46 Clinchers

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Tires for Reynolds DV46 Clinchers

So far I'm having trouble picking a tire to run. I train on my race tires (and wheels). No time and or too lazy to be changing all the time.

I picked up the wheels used, and they came with The Vittoria Open Corsa CX, a tire I never rode before. Loved the ride, but blew a tire off the rim at ~110psi. While riding.

So I put a GP4000s on the rim and it was murderous. I usually only carry one tire lever, but this tire takes three levers to get on an off. VERY TIGHT FIT. I feel confident that it won't blow off the rim, but not so confident about not pinching my spare tube trying to fix a flat.

I never had any issues with mounting tires on any other wheels sets. RH550. Rolf Elan. Bontrager Race XXX Lite. All have been the same. But these wheels defy my common sense. The Contis are murder to get on, yet the Vittorias blew off the rim! Does not compute!

My PR3's currently have a 1/4 cut (booted) from glass or metal, so I havent tried them yet. Need to replace them if I'm going to run PR3's.

What tires do you find you like with these wheels, and why?

Don't know about those wheels but I like Vredestein Fortezza Tricomp, shouldn't be a problem mounting them and they have a great balance of performance vs durability.

Either the Vittoria's were not mounted correctly or they were defective; they should not have blown off as they are rated for 145 psi.

I weigh 140-150 lbs and run the Vittoria Open Corsa CX @ 120 psi on one of my bikes. If you love the feel of the Open Corsas as much as I do, it might be worth trying out the Open Pave EVO CG. They are a lot more durable, have an almost similar feel, and they come in a cool, green color.

I tried the Vredestein Fortezza SE once but did not like them compared to the Open Corsas. They were much more sluggish and didn't have the smooth, rolling feel. Also, they didn't grip as well in the corners.

FWIW, almost all they guys I ride with run the Hutchinson Fusion 2 Ultras. The only reason why I use the Vittorias is because that's what I started with and they seem to work...

I have DV46cs with Michelin Krylions. They're no more difficult to mount than any other tire. I run 110-130 psi in them, depending on my mood.

I've trained on them exclusively for about 1.5 years now. I rode them on the trainer, outside, over glass, etc. I cut/flatted 4? PR2s on the same roads in 2-3 weeks (twice in one day), and I have a reasonably conservative riding style - I flat maybe once every 2-4 years on the road. I moved to the Krylion and haven't flatted in over a year. I swapped tires after they started to wear, then I moved the worn tires over to a set of box section clinchers (which I am riding now).

I raced the wheels a few times when my tubulars were out of order, crits, one a short two turn course, the other at Bethel (no turns, hill). They cornered fine (p123 race, fast, single file much of the time, hard turns), they're within 1 lb of my tubulars so I consider them light.

Tires won't blow off unless they are mounted wrong or the tire is defective. If the tube has a long gash in it, it was the mount job. The Reynolds rims are rated to a high enough pressure that tires will blow off before the rim explodes. I think a friend mentioned 275 psi as the pressure where the tire blew off a Reynolds rim in their lab, but I may be high on that number. It was stupid high, whatever it was. He was pointing this out to contrast the rim to Campy's 118 psi rated max - the Campy rims exploded at something like 150 psi, and they had to buy the wheels at full wholesale for that experiment (!).

I threw my PR3's on to see how the ride compares. The PR3's ride great - somewhat smoother than the GP4000s and way easier to get on and off the rim.

After my 60 mile ride tonight for confirmation, I'll probably be ordering a new pair of PR3's to use on these wheels. the Conti's just aren't worth the hassle.

I may try Vittoria Open Corsa CX's again later this year. Not sure.

BTW, Vittoria is now selling the OC EVO CX II, which has an even higher TPI (320), which should make the ride even more sweet and rated for 200 psi.

DV46Cs have a shallower "well" in the rim than most aluminum rims. So mounting any tire will be harder. I suggest using thin rim strips. "Rox" strips are the thinnest I have seen. When installing, take extra time making sure that the tire bead is in the center of the rim where the diameter is smallest.

I run GP4000s' on my DV46c's, and they're a little snug, but certainly didn't take three levers.

FWIW, the Fortezza SE is one of Vredestein's low end road tires. 50 tpi casing as compared to 120 for the Fortezza Tricomp Mongo was referring too. I'm pretty happy with the Tricomps though I also want to give the Vittorias a try....

Schwalbe Ultremo. Best racing tire, and the bead is a bit strechy so they fit any rim just fine. Wouldn't want to train on them though because the sidewalls cut up really easily.
