Pirelli P Zero Race TLR SL-R Road Tire

SUPER stable tire.

After riding 1k miles on these I am very satisfied.

Not as supple as the TLR-RS, likely due to the sidewall reinforcement making them more harsh feeling but nothing dropping a few psi won't fix, just something I noticed.

That rim to tire transition is so incredible and makes for the most stable tire I have ever tried, hands down. I compared to Conti Aero tire up front and really do enjoy this tire more than the Conti aero tire.

My 28mm tire measures 31.8mm on my 26 internal rims after stretching. I expect they will wear fast but so far they are holding up quite well for the first 1k miles and zero flats.

First, the Good. I bought 6 of these in 30mm for 3 bikes. These tires feel very smooth, grip well, mount well on 3 different wheelsets and overall, I had high hopes. They were rated well in all articles and testing I seen. All 3 wheelsets used are 25mm internal and 34 or 35mm ext. The tires measured 33mm wide after 2 weeks of being inflated to 58 to 64 psi.

The Bad. Weights- 286, 286, 294, 294, 301, and 313 grams. Weights are all over the place. Puncture resistance is poor. 4 tires got a very small pin hole in less than 500 miles. All 4 tires sprayed out the entire 2.2oz of Silca Ultimate sealant over the next 40 miles. Tried Stans and also spray out the entire amount. These tires DO NOT seal. Happening once, could be a fluke but 4 tires not sealing and acting the same way is hard data. Tried the Small bacon strip from Wolf Tooth and it split the casing leaving me stranded. Very brittle casing. Plugs DO NOT work either. Carry a tube and lever as back up. Sealant and plugs will NOT work with these tires. For me, all other tires have sealed up with pin holes but these. I have a set of Schwalbe RS pro 45mm that had a 1/16 inch diameter by 2.5" nail go completely through the tire, was rattling around inside the tire and it is STILL sealed from last fall with Silca ultimate. No plug needed. Silca Ultimate lasts forever.

Because of the very high price and low puncture resistance, I plan to go to Conti 5000 S TR 32mm in rear and the new Aero 111 32mm in front next year. A little bigger, as the roads are getting rougher, rims wider and frames suited for 35mm or larger measured tires. Less fatigue after 40 miles into a ride means more comfort and power for the next 40-60 miles. For me, Conti's have always sealed up unless it was a cut then a plug with lower pressure would get me home.

The smmary box days t all. I've been riding this for about a month or so now, granted, I went from the previous pirelli p zero top of the range with 60s to 36s Hunt HD36 carbon spokes. So far, i've PRd every 10k, 20k, AND 20 mile segments by about 1mph. Could be a combination of both, but regardless, this is the middle of summer! They're grlppy and supple, def switching to these on my other hoops

These tires should be considered in the top tier of road racing tires available, maybe the best? The ride quality and cornering grip are amazing, certainly right there with Vittoria, and the suppleness is better than Conti; hard to know, as a user, the rolling resistance and aero benefits, but so far so good on durability'.

Just got one for front tire. Super easy to get on and set up tubeless. Super faired in at wheel as designed. Especially fair with my ICAN G 25 wheels. Had one ride 30 miles and felt supple and fast. Ran at 45psi as predicted by the sram model 60 kg. If durability is good will change over rear GP5000 str
