Approved Tyres List ?
Omni, I think most of this tyre noise is from owners over emphasising comments rather than serious issues thrown up by dealers.

I agree, I had a set of N0's on the rear and N2's on the front while I waited for the rears to wear out. Dealer couldn't have cared less, they noted it on service paperwork and that was it. If it's a full set of N2's there's no problem.
I have a pair of A0s, similarly noted, but was told by the SA, sadly only verbally, that it isn't a warranty issue.

Legally - the correct size, speed rating and load carrying capacity. The rating for the last two can be higher than OE, but not lower.
Porsche [and other manufacturers] with approved tyres - extensive research and development is under taken by the vehicle makers with the tyre companies. Construction, materials deployed and compounds are tweaked to optomise the performance window for each vehicle. Approval is only given to a select number of tyre manufacturers in each case. Porsche then authorises the N designation for that specific vehicle. With some highly specialised models, only one tyre may be approved.
If you want the very best performing set of tyres for your Porsche, then N-rated with matching numbers. The tread depths need to be within 3 mm of each other front to rear and with matching depths across each axle. Nomillay tyres have 8mm from new, a very few less / more. The legal limit is 1.6mm across 3/4 of the tread surface. Although on high performnce cars a minimum of of 3mm is advised and for anti-aquaplaning on all vehicles.

Good stuff Steve, but correction on tread differential across axle if I may, from Good to Know:SAC1 wrote: ↑Mon Oct 11, 2021 11:16 am Legally - the correct size, speed rating and load carrying capacity. The rating for the last two can be higher than OE, but not lower.

Only fit tyres of the same make with the same specification number (e.g. “N0”, “N1”, ...).
▸
Before fitting new tyres, find out about the current approval status: Contact your Porsche partner.
▸
Only use tyre makes that have been tested and approved by Porsche.
▸
The difference in tread depth must not exceed 30% on one axle.
▸
Only use second-hand tyres if you know their history.
▸
Always replace both tyres on an axle so that different profile depths will not unnecessarily influence vehicle handling.
▸
Tyres should only be fitted by professionals.
Visit a qualified specialist workshop. Porsche recommends a Porsche partner as they have trained workshop personnel and the necessary parts and tools.
▸
Adapt your driving style to the changed vehicle handling.
I don’t believe there is a limit front to back as the transfer box will accommodate large differences. And no, it’s not the reason for TB failures!

I’ve never bought tyres from a main dealer they are always 50-100% more expensive for the same tyre.
Well I inspected and bought a macan this afternoon, the uniroyal rainsport 5 tyres fitted are less than 200 miles old so I’ll be keeping them for a few months, I cant think about a Porsche warranty inspection for the first 90 days so might as well run the current tyres for a while.
