I didn't want to revive an old thread since there are so many new model tires out...basically looking for some clinchers that have good wet/damp traction. Went for a ride on Redwood Road/ Pinehurst Rd in NorCal yesterday and too many white knuckle moments and loss of traction standing up out of the saddle on climbs as well. Corners were damp from tree shade.

Tires used yesterday ofcourse have been great in the dry.. Vittoria Corsa Speed G+.. I have already removed them and stuck on Conti GP4000sII which trust a little more. I still want a low rolling resistance type tire so what do you all say ? Outside of Conti GP4000s/Corsa Speed and Turbo Cottons I have not used any other clincher tire in years.

I have tubular Veloflex Arenburgs as well.

So I know this is not what you asked...but you mentioned tubulars.

The Veloflex Vlaanderen appear to be a great wet/winter tire. I have to admit our SoCal wet history is not so good and when going up north and dealing with rain, we always found some kind of flat trouble.
I bought the Vlaanderen this year 2016 for my kid thinking he'd do junior Paris-Roubaix. He didn't, so sent them off to school in CO and he's been rain and slush and dirt riding them constantly (not mud). He carries no spare (guess the part about not being risk adverse). They are thinner tread than many so likely not a good glass, wire, goathead thorns, but for wet, rocks, pot holes, light road film they are a great tire. They inflate to 28mm and weigh about 320g.

I also vote gp4000 sII. Specialized S-works turbos feel on par with them in the wet but last half as long, if you have a hookup and would like to give them a try.

I've been pleased with how long the s-works turbos last. Seem to be on par with GP2Ks for me and feel better, too.

TheKillerPenguin

Probably cuz I'm fat!

I can get 4-5k miles out of a gp4000, the s-works I rode over the summer were about 2k before they went threadbare. I definitely like how they corner though, their profile is more round than the contis.

spectastic

gp4ks are pretty hard to beat.

I would also recommend disc brakes, but that's kind of off topic.

my experience has been that the more race-oriented tires (vittoria corsa, specialized TCs and similar) last ~1,500 miles (rear) before they become flat risk for me.

the conti gp4k's are great tires for many reasons (but definitely do not have the same subjective ride quality as the above tires), but they last much longer. for me, they are shoulder-season tires.

and, yes, the gp4k's are great tires, relatively low rolling resistance, good aerodynamics ... they just don't *feel* the same on pavement (same pressure, same volume tire, same bike/wheels).

hack

Ha ... yeah, 4k, not sure why I wrote 2k. Maybe I've been using some knock off tire and haven't been aware. I feel like I get more than 1,500 out of my Sworks turbos though. I'll have to backtrack and see what the mileage is. I put a new pair on for Cascade and they're still good to go.

Ygduf

last half as long. 2ks. on par.

get the 4ks, man.

hack

2ks are light though ... saves like 10g per tire.

How about some tubeless recommendations for winter tires in NE US?

And 25mm vs 28mm?

I really like the feel of IRCs. Close to tubular.

nycphotography

Which ones?

mattm

Yes.

I advertise them so much that Amazon sent me two of them free the other day (on accident, but I'm not complaining or telling them)

I race on gp4ks as well, but thinking about something fancier for next season.

Came here to say IRCs - two seasons of racing tubeless in Seattle and never a single issue.
Even the "training" ones are super sticky, feeling planted in corners is great.

how are disc brakes going to help... I lost traction going into corners not being on the brakes and out of the saddle climbing

looks like GP4KSIIs then... which is what I have on now after this scare. I have Sworks Turbos on my DA C24s and those have been alright, but a few more flats then I am used too. Come to think of it, I got caught in the rain a couple times with those, but there was no mountain switchbacks.

I like the formula light.

spectastic

much better modulation compared to wet, gritty rims.

spdntrxi

I understand all that... what you keep missing is that I was not using brakes

spectastic

like i said, off topic. I offered advice, you don't have to take it

tetonrider

tangent... did you know amazon has a specific reason code 'received item by mistake'? i've actually used that before. i've also had a couple scenarios for low-priced items where i initiated a return but amazon said (via the automated process) 'keep it.'

Indeed, I have seen that - but will never use it. =]

Also a fan of the GP4ks. use them as a training and racing tire. now also using a GP 4 season tire from continental and that looks very promising as well, might be a bit more hard wearing than the GP4ks. price difference is marginal between the two though.
