Hi guys, new here and have a question about tyre sizes.
My 2001 Boxster S Tip is in need of new tyres. I am in South Africa, so we only use summer tyres here year-round. When I bought the car about 2.5 years ago, it came with the incorrect tyre sizing on the stock 17" wheels - 205/50R17 front and 225/45R17 rear instead of a 255/40R17. The current tyres are also run-flats. I decided I will change tyres when needed. Now is the time and I am having an incredibly difficult time finding the stock sizes as a staggered set.
The only tyres I can find locally that will be stock sizing are:
- Bridgestone Potenza Sport (super soft and will get little mileage, plus $$$)
- Dunlop SP Maxx Sport 050+ (not really a Dunlop fan and reviews don't inspire)
- Davanti DX 640 (not a familiar brand and reviews are inconsistent - very cheap as well)
Nothing else has a staggered set and the Porsche dealership can order me a set of Michelin Pilot Sport 2s, with a lead time of a few months as they are being specially made on order - at almost double the cost of any other option from a tyre shop.
Ideally, I'd like to put on Goodyear Eagle F1 Asymmetric 6s - but they don't make a 255/40R17 in the tyre.
A 245/40R17 would make the diameter of the wheel 9mm smaller than the stock front 205/50R17. A 225/45R17 is closest in relation to the front and compared to the 255/40R17, and I can't say that the current setup has been anything less than confidence inspiring with great handling.
Would a 225/45R17 on the rear be my best bet if I can't get a 255/40R17 for the rear?
