It’s been 4 years since Pirelli returned to biking with their P Zero highway race tires. And now these authentic clinchers get most of the identical tech updates which have popped up within the years since on professional tubulars, then highway tubeless tires. Now these driving clinchers and inside tubes get the identical upgrades to rubber compound, casing, and larger sizes…
Pirelli up to date P Zero Race & Highway clincher highway tires
4 years in the past, I visited Pirelli’s manufacturing facility and racetrack proving grounds to get the within line on their P Zero Velo highway bike tires. These clinchers have been widespread, however now highway riders that use tubes get some up to date tech – and a little bit of renaming to maintain all the pieces easy & constant.
The unique race-targeted P Zero Velo, now turns into the P Zero Race. And the unique four-season all-rounder P Zero Velo 4S, now turns into the P Zero Highway. Gone is the lightest, no safety P Zero Velo TT tire, as final velocity & low rolling-resistance appear to definitively favor tubeless now.
What’s new? Tech particulars
First up, the brand new P Zero Race will get new SmartEvo Compound rubber. At all times one in all Pirelli’s sturdy factors primarily based on their motorsport’s expertise, the brand new rubber once more blends three “functionalized polymers” into the combination to ship improved grip with low-rolling resistance. It seems like the identical kind of secret sauce, nanotech combination as earlier than, with Pirelli merely claiming extra incremental enhancements through the use of the identical top-spec rubber & tread design as within the latest tubeless P Zero Race TLR tires. The P Zero Highway tires get simplified with a brand new Evo Compound rubber mix that prioritizes longer sporting.
Subsequent up, the tires get wider. Extra than simply greater sizes, Pirelli has up to date the brand new highway clincher tires to work with extra trendy rims. Primarily based now with a hooked 19mm inside ETRTO 19c rim, every tire will get a wider tread for a similar casing dimension, designed now round a shorter, wider contact patch. The brand new 19c-based P Zero Race now is available in 26, 28 & 30mm sizes, with the tires themselves being about 1-2mm wider than the unique 23, 25 & 28s on their authentic 15c design rim.
Curiously, the brand new P Zero Highway is predicated on an ‘in-between’ dimension 17c rim, presumably on the pondering that the extra endurance-focused tire will find yourself on older bikes with narrower rims maybe? In that case, the P Zero Highway is available in smaller 24, 26 & 28mm sizes (that will really measure out at 25, 27 & 30mm on a 19c rim.)
Lastly, there are new casings, with some wider footprint-specific updates, too. Right here the tire building is all-new, that includes a light-weight, vulcanized 120tpi nylon casing designed for use with an inside tube. Inside each Race & Highway tire, the aramid fiber TechBelt Highway puncture safety will get wider too to cowl the tire profiles newly made wider by these wider rims.
Pirelli says that dialing in match to your highway rims and excellent strain is extra essential than ever with the extensive variation in wheels and driving kinds of recent highway riders. So to get probably the most efficiency out of their new P Zero tires, Pirelli is sort of useful by offering detailed charts on their packaging and simply discovered on their web site to dial in your setup. From actual anticipated WAM (width as measured) & RAM (outdoors tire radius as measured) to strain suggestions, Pirelli makes it simpler to know what you might be getting, and get probably the most out of a brand new set of tires!
