Pirelli P Zero's

[LudicrouslyJuicy]

Hi guys

Have a set of 4 new pirelli p zero 225/45/r19/Y96 installed a john cooper works countryman.

Unfortunately, the front right one had a puncture a couple of days which I paid to have repaired (took the tyre off, mushroom filled it and put tyre back on). They've only done 600 miles and the tyre appears to be repaired well and holding its PSI well but I still feel uncomfortable with a puncture repaired tyre on a car like the JCW.

Had a look for a new one and surprised to find out it's quite hard to get a hold of and the few online retailers that have it are charging 220+ per.

I've read so many bad things about the PZeros that I am wondering if a) I can keep driving on these tyres until they're done b) if I should get a different set instead of buying another Pzero?

If b) what would be the right tyre to go for bearing in mind the car is intended to be high performance (300bhp+ 4WD)? Eagle F1? Michelin PS4?

Here are the pics of the screw that went into the front right tyre

If it’s been properly repaired and is holding air it’ll be fine, regardless of is your Mini has 300bhp or 30bhp.

Are you unhappy with the performance of the Pzeros, or are you just going off reviews you’ve read online? The only complete I have with PZerosis the wear rate seem to be more inconsistent than other tyres.

I would say the car handles well on the Pzero's even when driven pretty hard but i was out and about this evening and surprised to see the car skidding a bit with the slightly damp roads even on moderate acceleration. I had the Pzeros on a previous car and they wore out rapidly, in about 6 months and about 6000 miles.Road noise is kind of high too and the ride is a bit jarring though I think this is due more to the 19 inch rims and the stiff suspension so not sure there will be much difference using a different set of tyres. I have heard that the michelin PS4 and Eagle F1 ride quieter but that's anecdotal anyway.

I was just thinking if the one tyre should be replaced (sounds like it doesn't need to be) and the Pzero is universally considered just "okay" there would be no reason to pay for a new one when it is so expensive and might be better off just getting a better set

A correctly plugged tyre, especially where yours was in the centre of the tread, will be fine for the life of the tyre. stop worrying about it and use it as per normal.

yea I hear what you are saying, my concern was that the tyre shop said it should be replaced as the screw was embedded at an angle so they couldn't be sure the repair would hold for the life of the tyre. I'm just scared the tyre might disintegrate or something while im driving one day lol

That's not strictly true, the OP may have driven miles on severely underinflated tyre and regardless of how good the patch is, the tyre is scrap.

Op did you see the tyre being repaired? When it came off the rim was the tyre full of rubber shards/debris?

Your tyre shop told you their repair may fail? They repaired a tyre in a way they think may be dangerous?

If that is true they sound like a bunch of idiots.

Did they do a proper repair with the correct standard?

A competent repairer would refuse to do the repair in those circumstances.

Unfortunately no, they wouldn't allow me into the area where the tyre was being repaired.

I got the notification of the sudden drop in tyre pressure at about 30psi, by the time I got home it was 29psi (about 1 mile later) and then the car was parked for a bit. Took it to the tyre shop a bit later which is about 1 minute from my house - dropped to about 6 psi half way through the journey. I stopped, temporarily refilled air with my portable inflator up to 14psi and then carried on to the shop.

No not in those words. They just said, the tyre is good to go. I asked should it be replaced? They said yes we think so because the screw went into at an angle as opposed to straight in vertically. So technically your tyre is fine to drive on and could last like new and we've repaired it using muchroom repair but no guarantee.

Maybe I should replace the tyre for peace of mind

It sounds like you dealt with idiots and you are asking for permission to buy a new tyre.

Just buy a new tyre, it's only money.

Next time don't use idiots.

I don't think I've ever heard of a repaired tyre in my motoring circle fail - that's about 20+ cars in my immediate family, and 100+ vehicles in our company before we sold it.

[irocfan]

"Dear retailer of tyres should I buy a new, expensive tyre or should I stick with the industry standard, cheap, repair you've already done?"

I'm surprised that they didn't recommend you replace all 4 tyres on the basis that different wear between new and part worn could upset the 4wd brain

[alfasud1]

What’s peace of mind worth? It will be at the back of your head every time you drive it

Jon's recent tyre test showed that 'summer' tyres don't do well on cold damp roads and my own experiences have been similar, including the P Zeros on my Insignia but also a variety of other brands (Continental, Bridgestone etc).

I had no problems with P Zeros on my 335d. However, When they got low enough, I swapped from 19” to 18” and went to Goodyear EfficientGrip, which were quieter and tolerated road humps better.

Have run repairs on 200bhp motorbikes many times with no issues.

Read any of the performance car forums and p-zeros are generally hated. Michelin PS4S or Goodyears seem to get far better feedback.

[fatboy b]

I ditched p-zeros on my Jag for MPS4S. The difference was night and day and shows just what a crap tyre the p-zero is. Apart from the lack of grip in the wet, the last p-zeros on the rear managed 8k miles. I’ve just replaced the MPS4Ss after 20k.

I also ditch Michelin Premacy on the Cooper S for MPS4S. Same transformation in handling.
