Pirelli P-Zero Race TLR RS - New All-Rounder King?

[208]

What do you mean by springy? Less supple?

Not necessarily less supple because my sense is it’s the compound itself having that quality rather than the casing/sidewalls.

How do they feel vs gp5K?

I'm tempted to do an a/b test of rs vs s tr once my new wheels come in next month

First ride on the 30mm RS. Like ultyguy, I really can't feel a difference between them and the non-RS Speedcore tire. They have the same pointy shape, they have the same audible road buzz and a springier feel than the SES Race Days I just replaced. They don't feel better or worse to me, so the audible difference is the only thing that really stands out.

After one ride, they measure ~32.2mm at 60psi on 23mm rims.

These should be way more durable than the SES so if the only difference you can tell is sound, that's a pretty good thing

Quick update on my 28mm RS, I initially had a hell of a time getting them inflated and had to blow them up with co2, and the plan was to then deflate them and add sealant via syringe but one of the tires unseated in the process of this and I had to start over. I used only 30ml of sealant initially so after 600 miles wanted to add more and this time when I deflated the bead did stay on and I was able to add sealant and then reinflate with a floor pump. No punctures so far and am happy with them.

I have a set of these waiting to go on a friend's pair of ENVE Foundation, so will see how those do with the floor pump.

Can’t imagine how the RS would have trouble seating. They’re some of the tightest tires I’ve ever fitted and they were already completely airtight when sitting in the center channel. I was able to seat them with a floor pump at a stroke rate of once per 2 seconds basically.

Yeah I was pretty defeated and the S TR I replaced blew up easily like your experience with the RS. I even tried swapping the tires between rims and still couldn't make any progress. Hopefully the next set works out better

I’ve been using the P zero for a while now in pre-Italian, Italian Speedcore, and now RS versions as well as the Conti TR.

Splitting hairs as these are all good tires but my personal sense is that the Conti is a tad faster in a straight line but that I have more confidence leaning over the P Zero. The TR feels just a tad squirmy sometimes under pressure imho.

The RS has had a higher wear rate for me and was a tighter fit than the Speedcore and to be honest I couldn’t tell a functional difference between the 2.

It must be just some kind of impression, not like the tire is really faster or slower, bacause it's not possible to feel the difference of a fraction of a km/h, nor even measure such differences in real world conditions. So maybe it's something about increased comfort of a tire?

[TobinHatesYou]

Does anyone have WAM and weights for the 32mm size?

No WAM, but:

340g (335g claimed)
81mm wide case
32mm wide tread
39.5% tread coverage which matches my 30mm sample (30/76mm)

How does the wear rate compare to GP 5000 S TR?

Put the 32 Race RS on wheels with 24 id. Blew up to a little over 33mm initially. Installation wasn't as straight forward as with other tires. Hard to mount and couldn't seat them with a floor pump. Needed the compressor and some fiddling.

Then crashed on the second ride...Wet roads, but went through this corner close to home a hundred times before in similar conditions with similar speed with less grippier tires without problems. Bad luck i guess.

New tires don't corner well in some cases.

I believe it's the tire, not bad luck.

The compound is supposed to be grippy in the wet. Question is whether the shape of the tire works well in the wet... They do blow up quite oval.

As Wheelbuilder says above, most tyres appear to have a protective coating on them when new and need a couple of decent rides to wear them in and get tem performing as desired.

I did a long ride the day before so they should've been free of any residues from production.

[cyclespeed]

I have 2 of these arriving soon in 28mm as I am not happy with the wet grip of the Conti GP5000S TR or TT.

I figured that it's worth the slight weight penalty to get better wet grip, longer life, and better puncture protection.

Also found them for 55E each which helps.....

[BBres]

Eh, I am still torn. That's not a good information that the tire failed in a wet corner - assuming that it was not a bad luck, let's say some spilled oil or the protective coating of the tire still in place. Also roads tend to be more slippery right after it starts raining.

[eins4eins]

I just mentioned it because it was a weird coincidence and kind of funny for me, that i just crash when using arguably better gripping tires than what was one the bike before. Realistically, this one incident doesn't say anything about the tire capabilites.
