I am relatively new to the performance car game but I am the happy owner of a 928 S4. I enjoy the car's performance but I am not taking it to its limits. I would appreciate some advice about tyres.

It is currently fitted with 5 year old Continental ContiSportContacts all round. The rears have about 3.5-4.0mm tread left and the fronts 6-7mm.

1. While some way off the legal minimum I wonder when people would recommend replacing tyres, especially the rears which carry the power! I am happy to replace them when appropriate but there is no point in wasting rubber.

2. ContiSportContacts are no longer available! And the choice of 245/45 R16 tyres is very limited. For many options no front 225/50 R16s are available. The only options for both axles seem to be Pirellis - P-Zeros or Cinturato P7s. Is it advisable/acceptable to mix tyre types front and rear?

3. One reason for asking is that there are cheaper W+ rated tyres available. The other is a very practical one - if I cannot mix tyres and I cannot get Continentals I will have to replace all four tyres simultaneously...£££££!

Many thanks for comments and advice.

Hi, thanks for these posts. Much food for thought.

The tyres look to be in good condition so I am not rushing this.

I take the several comments about uncertain performance with different tyre types front and rear seriously. I may stagger a purchase for cash flow reasons but I am not doing much mileage at present and certainly not taking the car to its limits. When I buy I will eventually replace them all but I will regret the waste of rubber on the front.

I am fully aware that owning a 928 is not a cheap hobby but I will spend where I need to spend. I realised that tyres were not cheap before I bought the car. I am not going to buy new wheels! The cost of new alloys (and possibly cheaper tyres?) would be vastly more than a new set of rubber, I do not have storage for a second set of wheels and there would be additional costs in getting larger wheels properly fitted. I am not looking to pimp my ride and if I had £3-4000 to spare it would go on something else!

Tyre choice is limited by the 245/45 R16 rears which are now a rare breed. Choices seem to be Yokohama Advan A052s, Pirelli P Rosso Assimetrico (at a similar price) or original spec Pirelli Cinturato P7s from Longstone Tyres. I am seriously tempted by these Cinturatos as they would keep the original character but they are the most expensive option (although not by much).

Thanks again for your suggestions. I feel much more confident going ahead with a decision in due course.

All would fit the speed and load rating needed.
