Pirelli P Zero Velo folding tyre

tubeless or not?

hi, i cannot find any info if they can be used as tubeless... anyone knows or tried?

thanks

I put these tyres on my bike and rode in the alps on both wet and dry days.

Felt like an improved version of the Conti's.  Maybe more similar in feel to the Vittoria Corsa's but with better puncture protection.

Can thoroughly recommend them.

Just to give my additional two cents. BicycleRollingResistance guys are great. I really do appreciate their laboratory approach to benchmarking tyres, which cuts through a lot of the marketing mambo jumbo. However, focusing solely on data figures in buying your tyre would be flawed in my opinion. The tests are imperfect to grip, cornering, braking, durability and "feel". Also, tests are performed using only single tyre each (sampling problem) and there is also volatility here. I.e. buying same tyre again and re-testing will produce somewhat different results.

Conclusion: BicycleRollingResistance guys can help you a lot in benchmarking tyres but it won't tell you all. 

Also, argument that P Zero Velo is to the "similar level" to the existing top tyres (Michelin Power Competition, Conti GP 4k S2, Schwalbe One), which will make them inferior very soon (with the new generation)...I'm not so convinced. I'll give an example. Conti keeps producing tyres with the magical Black Chili compound (GP TT, GP Force/Attack, GP Supersonic, original GP etc.). You can get the feeling that Conti pushes it to the limit (varying thickness of the thread, protection layer etc.), with clear balancing out element and "no free gains" conclusion, at least if you ask me. I.e. all of those tyres have a clear hierarchy and conflict between speed/puncture protection. I'm not sure there is a massive gain out there (speed improvement without loss of puncture protection and durability). Concluding, P Zero seems like a good tyre. Expensive? Yep, I got two Conti Grand Prix for the price of one Pirelli - which I rate 80% of GP 4000 S2 for 50% of the price.

According to the ever reliable Bike Rolling Resistance guys, these brand new, ground breaking tyres have a rolling performance of the same or slightly less good as the current generation of top tyres, Conti 4ks, Vittoria Corsa etc. 

Dissapointing. Move along. 

Not convinced and the reviewer doesn't understand rotational weight otherwise would dismiss any weight saving given it's tiny and also doesn't make a point of measuring the actual width of the tyre to compare directly with others on the same rim.

The sidewalls on these are wafer thin, only the Vittoria Speed and Continental TT are thinner, as for the wear/durability. Being impressed with a 1,000 miles on a front tyre for a lightweight rider just shows you how low some people's expectations are.

That these are maybe just on a par with an 'old' tyre like the 4000sII just shows you how far behind Pirelli are with their 'top tyre'.

30%ish higher of £30 is Pirelli's RRP. What is Conti's RRP? Exactly...either way, the price of Pirellis will come down in few months to £30 or less and they will be competitive to Contis and Michelins and to everybody's liking. More choice is good!

If only Pirelli had thought so long and hard about wet performance in their F1 tyres, might have saved me a three hour wait in the pissing rain at Monza the weekend before last.

The GP4000's on my main weekend bike are nearly at the wear markers  after a good 5800km and these new Pirelli's are tempting to try given the 15g rotational weight reduction. Despite trying a few other tyres I still keep comign back to 4000's - they seem a great all round (8/10 in all areas) tyre. One exception was the Schwalbe Ones which I found to be slightly quieter and slightly better grip in the wet on tarmac surfaces that are just stones laid on tar - so many of the country lanes round here are like that so a spare pair of wheels have them on - on smoother surfaces in the wet the 4000s still seem better though. The measured Rolling Resistance on another website at 80 PSI (my preferred pressure for a 25mm) slightly counts against the Pirelli's and I wonder if they will last as long as nearly 6000km? Is it worth risking to find out? In the end I think I will stay with GP4000s and swap the inner tubes to latex. Gives a similar weight reduction.

My winter bike runs GP 4 seasons and the Pirelli P Zero Velo 4S (not reviewed above) look a more appealling option ( lower weight, lower rolling resistance vs GP4S) and hence I will put my money down there when the GP4Seasons give up the ghost

I've tried all the popular tyres, Conti GP4000Sii, Schwalbe One, Veloflex Corsa, Vittoria Corsa and Rubino G+ and recently took a dive and bought the Velo 4S in 28c size. These things are astonishingly comfortable. They roll on to the rim the easiest of any tyres, they feel fast, haven't punctured in 500km so far and evidence of wear is non existant. the grip around corners is the best I've expereienced. I know these aren't the standard Velo's and have a bit more tread on them but I'd imagine the Velo's here and even more supple (which is hard to believe). I'm a big fan, and if my luck continues with these 4S's, I've found my favourite tyre. Btw, I frequent roads and well and rough trails........

Bicycle Rolling Resistance have also tested the range, so if you are into numbers, check that out. Numbers aside though, these feel sensational

My experience of Pirelli tyres on a car is that they were fantastic in the dry and terrifying when it got damp - My Dad says the only car he's ever spun was on Pirelli tyres and he used to do quite a lot of rally driving.

So I hope these bike versions aren't the same as that.
