James Mitchinson Posted February 23, 2022 Share Posted February 23, 2022 Hi all, I purchased my first Porsche a couple of weekends ago, a 987.1 Cayman S. I’ve had a smile for each of the 800 miles I’ve already put on it in, with the exception of a few metres when the back stepped out going around a dry roundabout in 2nd gear at less than 3,000 rpm! Having checked the tyres I’ve found that the rear left is from 2012 with the rest being 2014 and 2015 (fronts). They’re Bridgestone Potenzas and whilst it wasn’t a warm evening I’d been driving for some time and it was above 5c. Tread levels are 5mm or above on all four corners. I have three questions that I’d really appreciate some thoughts on: 1) is it acceptable that the specialist sold the vehicle with tyres of this age? If not, what’s my best course of action? 2) is the tyre age likely to be the cause of it stepping out at relatively low speed/revs? 3) what is the recommended replacement tyre? The car is used all year round and will be doing about 5k mile a year (that’s if I can stop making up excuses to go for a drive every day!) Thanks very much in advance for any advice, I’m aware the tyres are something I could and should have looked at before buying the car but I overlooked that with all the excitement.

Julian987 Posted February 23, 2022 Share Posted February 23, 2022 1. They are just on the cusp of the legal limit then. If the tread has fallen below 1.6 mm and the seller knew via an MOT report then consider this case.... https://www.bbc.co.uk/news/uk-england-beds-bucks-herts-59728543# but it is your property now. 2. You need to get them changed as that effect is what is reported to have happened in that recent death of a driver. 3. https://www.michelin.co.uk/auto/tyres/michelin-pilot-sport-4-shttps://www.blackcircles.com/tyres/brands/michelin/pilot-sport-4-s Link to comment Share on other sites More sharing options...

Mavrik Posted February 23, 2022 Share Posted February 23, 2022 Indeed, as tyres age the rubber becomes harder giving less grip due to the amount of heat cycles. Personally, I'd change tyres after max 6yrs of use. The general consensus (not that I agree, mind!) is that Michelin Pilot Sport N rated tyres are the go to tyre...

Not specifically N rated, just PS4S. 1 Link to comment Share on other sites More sharing options...

If they sold it to me with new tyres the price would have been more I bet, so either you (as in the original poster) pays now, or would have done at the time. Long shot to take it up retrospectively with the dealer - just move on. You could have a word with them, but cant see that amounting to anything other than a bigger phone bill. 'tis what it is. But do change them this week, otherwise every drive is a roll of the dice. Link to comment Share on other sites More sharing options...

PS4S is 19" and above, IIRC... Michelin N rated 18" would be PS4, which is a different tyre to PS4S and not as good. Link to comment Share on other sites More sharing options...

Impossible on my shores for the PS4S 18". I've since put on the Bridgestone Potenza for the rears. Link to comment Share on other sites More sharing options...

Its actually getting them which is the issue. Link to comment Share on other sites More sharing options...
James Mitchinson Posted February 24, 2022 Author Share Posted February 24, 2022 (edited) Thanks all for the input. Ordering these for fitting tomorrow afternoon.

The PS4 is still a much better tyre than what is fitted, even if the Bridgestones were new the PS4 wins hands down. Link to comment Share on other sites More sharing options...

I agree, the PS4 is still a good tyre, but my point was that PS4S is the tyre to buy. There's stickier tyres out there but they have poor wet grip. You can hold your own in a storm and happily do a track day on them. It's probably the best all round tyre on the market at the moment. Link to comment Share on other sites More sharing options...

Popular Post James Mitchinson Posted March 1, 2022 Author Popular Post Share Posted March 1, 2022 (edited) Update: The order I placed with Asda tyres ended up being cancelled due to an error at their end. This turned out to be a blessing in disguise as I subsequently decided to email the specialist I purchased the car from a few weeks ago. They acknowledged that the tyres were old and have agreed to replace them with PS4S at cost price. Realistically I think this is the best outcome, I get the peace of mind of fresh rubber on the car, the tyres that were my preference anyway and I'm sure the cost of the car would have been £1k more if they'd done this when advertising it.
