Approx 10 years ago I had a Vauxhall Vectra 1800, a gutless device it was too and it came with Pirelli tyres I was shocked to find that the tyres were delaminating on the inside edge and the wires of the carcass were showing. I was horrified because I have often had budget tyres and never experienced fails such as this before. Moving on a decade and the BMW 318 Touring I now own came with Pirelli tyres and the exact same fault has occurred with the wires being visible through the delaminating on one of the rear tyres.
I hasten to add that the tyre was kept at the 2.5 bar pressure as recommended, however I forgot to see how old it was, but assume about 4 years like the rest.
I replaced it with a Toyo tyre as I have never had any concern over these.

Interesting to hear,

I had the same sort of experience with Pirelli on both the BMW 750iL and 745i,
since then whenever I have changed the car, Michellin are specified, alas even
they have a problem, after 4 years irrespective of mileage, the sidewalls look cracked
and corroded.

Does anyone recognise what make of tyre this is? It was fitted to my Dolomite 1850HL when I bought it. I thought that it felt as though one of the tyres was a little out of balance. Scary to think I had been going at 70mph for a few hours on my journey home. I had no idea how old the tyre was and in those days I don't think they had a date stamp.

dunlop tyres used to do that, and my dolly 1850 has a full new set that was on when i bought it 6mths ago :(
i had pirrelli tyres on my last touran, they were totally useless in snow or anything slippy.
budget tyres seem the best bet, never had any trouble :)

I made tyres in a Michelin factory in the late 70s, they had a date stamp.

Doh, I just bought 4 new Pirelli tyres for my XC60 from BlackCircles. Its pot luck really whatever is chosen, and I guess any and every manufacturer can have a defective batch. Hope mine will be OK, they're certainly not cheap.

I have an ancient Cinturato that looks just like that, bulges and all! it's on a slave rim that's on my Sprint ATM. But it will never see the road again! I keep it cos, though it's bent as a nine bob note, it holds air for years at a time!

The Pirelli Scorpions on the back of the Land Rover are the originals and after 3 1/2 years they look absolutely fine with no cracking on the sidewall. Had to change the fronts as they were worn out after 18,000 miles, I think that was more due to the tracking being out a bit and the way I drive! Discovery's are very sensitive to wheel alignment and you have to have a dealer do it as they have to program the air suspension correctly.

Have to say that I have never had an issue with any modern tyres on a car and I always go branded, GoodYear/Dunlop/Pirelli/Contis.

The best tyres I have ever had on a car were some Good Year Efficient Grips on the front of my wife's Honda Civic. Worst were some Kwik Fit Centour Supremes on the front of a Golf VR6!

The Dunlop Street responses on RUK (1850 auto) are extremely good, especially in the wet. I found the budget Marshall tyres on NWL (Sprint) before I started restoring her just booming dangerous! especially in the wet, roundabouts were fun though! :lol:

Unfortunately I am still trying to get Farnborough Value Tyres (through Balckcircles) to pay up and admit that they damaged a diamond cut alloy on the Land Rover, they refused to give me the keys back unless I signed off the work. :fuming: I'll be going to Land Rover next time as they told me that they would match Blackcircles as long as I have the car services at the same time. On the other hand I had a tyre place in Bordon damage one of the alloys on my VR6 when repairing a puncture, they told me immediately and offered to either refurb the alloy or just give me the cash or money off a pair of new tyres. I went for money off some new tyres as the damage was so small.

My old Focus came with some Continental Eco Contact tyres which cracked very badly after about 16k from new so I binned them and for years and tens of thousands of miles swore by Pirelli tyres. Then I discovered Continental Premium Contact. They lasted much better than the Pirelli, wore better and were quieter. This experience put me off Pirelli for ages until I needed some tyres to replace the awful runflats on my old 1 series. The Pirelli P7 Cincurato was well reviewed and actually they proved to be very good tyres. They kept well, were quiet. didn't crack or fall apart and were grippy. I've also got Pirelli tyres on my Mazda which are lasting well, though the rears are getting a little cracked after 5 years so are due for replacement soon.

Now Pirelli only does eco tyres in the Mazda size so will probably look at Toyo or something like that which seem to be pretty good. I only buy quality brands of tyre. In fact my local Ford dealer once called me a tyre connoisseur because I declined their offer of no-name budget tyres.

Your Pirelli experience is unusual though.

Interesting comments about Pirelli as I replaced the P7 rears on my Sportbrake at 47000km and the fronts at 56000 earlier this year. No issues at all, although after a puncture (nail) I found a secondhand spacesaver rather than the sealant and pump that came with the car. Tyre and car combination has phenominal road holding.

Pirelli are not common in NZ, mostly Bridgestone, Goodyear and Dunlop through tyre retailers they own.

Only delamination I've ever experienced was on 'remoulds' back in the 1970s. One tyre also bad a big bulge on the sidewall. Mind you the A40 they were fitted to was so rusty that the lower part of the front wings flapped in the breeze. And it had an MoT! Oh, yes I did have Toyos fitted to the rear of the Sprint racecar de-laminate. I only changed to Dunlop though as Toyo stopped importing the size I used. Toyos were great sticky tyres!

I do hate the very low profile tyres though - I had Bridgestones on a 350Z and a few punctures. Problem was that the very low profile made it difficult to tell tyre was flat until cornering and by that time running on the sidewall meant the tyre was scrap and needed a new, expensive tyre. Eventually I fitted an unknown japanese brand of tyre for a fraction of the price of the Bridgestones - they performed just as well on the road and never got a puncture!!

It looks like it was always severely under-inflated judging by the wear pattern.

That rings a bell Steve. I noted what make it was at the time, but have forgotten since.

Yes, it looks as though it had been under-inflated for some time and it looks as though it had been run with the damage for some time judging by how it has worn next to the damage.

During the early-1980s, I experienced tread delamination with the Uniroyal Rallye 180, 175 SR13 steel-braced radial tyres, fitted to the 5½ x 13 inch Cosmic alloy wheels, on my 1974 Triumph Toledo 1300. At that time, the tyres were about 6½ years old and had probably covered less than 10,000 miles.

I had a Toyo tyre go after a year, wires exposed on the edge. I had the cars tracking checked, no problems, so it was the tyre. The cheap Chinese ditch finders i had before lasted far better.

To be fair to budget ditch finders, they all have to have stopping ratings now anyway. So budgets are nowhere near as bad as they were and are perfectly fine for normal road use.

I couldn't agree at all with this. I got some alloys for my MG last year for the MG. Came with new BCT S800 tyres fitted. They were quite good in the dry had no complaints but as soon as it was damp they were terrible. Grip went down the pan and it was like driving on ice, they were scary and I had police skid pan training. In fact the grip reminded me of the grip on the special extra hard rubber zero tread Uniroyal tyres used on the skid pan.

Earlier this year I purchased a Volvo V50 for my daily, dog carrier, shopping car. It came with 4 good tread depth budget tyres. First wet day on a long sweeping 70mph bend it felt unstable. Had invoices in the file with the car for them so know they were all fairly new so I did an online search. Two came back as c rated one e rated and one from the same tyre company fitted at the same time with a similar tread but different name, no rating found. Took those off and replaced them with A rated Avon's but still not happy with the wet grip and braking of the other two so replaced them a couple of weeks later with Avon's. Far better stopping and grip in all conditions and from Black Circles they were only just over £50.00 a corner fitted and balanced. At that price buying Chinese death rings doesn't make sense to me.
