My only advice is to buy only genuine Porche wheels ( & specifically Macan - some for Cayenne look similar).
There are indeed some excellent aftermarket wheels, but genuine Porsche will hold their value, either as eventual sale with the car, or as separate sale.
I’ve bought, sold, & refurbished several sets of genuine 20ins Macan wheels, inc. bought from Porche Centres ( with a discount off list no less !!) & via ebay.

Swopping between 20 & 21s is no issue - I recommend buying a trolley jack ‘puck’ via ebay to better fit the jacking points.
Use the wheel spigot from tool pack, to simplify the wheel bolt alignment and protect the calipers/inner rims. You require a torque wrench to tighten the bolts to 160nm

You may see reference to needing porsche rear wheel arch extensions - they are tiny plastic arch extenders available from the parts dept ( & inexpensive). If your Macan had factory fitted 20 or 21’s you already have them.

Tyres on their rims should be stored flat, not standing as in your photo.

Agreed - good point, well made.
These aren’t in storage - they were repainted (gunmetal) a couple of weeks ago, fitted with new winters, are going on my Macan in the morning if the rain stops....

Thanks for the info!

I'm planning to order a set of used wheels from ebay (buying new from Porsche is too expensive for me!) The photos I've seen looks good but I'm a little bit suspicious. Can you trust the dealers on the site? I see a lot of adds coming out from Germany and Poland. I don't want to end up with replicas or some cracked/bent rims.

If there is any other market place for used wheels or you know a good dealer please feel free to PM me the details.

I'm based in Sweden btw, thanks :)

Is there reason why they are to be stored flat? Mine are on a wheel rack so I can’t store it flat due to space.

Wheel racks are better than standing, but not perfect. Storing flat avoids the weight of the wheel and tyre combination causing a 'flat' on the tread surface if they are standing the floor, for example.

Ideally, spare wheel/tyre sets should be stored clean and dry in sealed air-tight and light-tight bags in a cool dry environment. It's OK for them to be stacked in fours.

Doesn't seem to be a great demand for the 21" Sport Classics wheels. Had mine advertised a long time still no serious buyers.

Guess I'll be keeping mine since the sale was supposed to finance the replacement wheels(20" RS Spyders).

The tires on mine are the michelin latitude sport 3, good tyres I suppose.

However, I'm wondering if there are other better alternatives to perhaps improve comfort, as in more rubber/thicker rubber on the tyres? The tyres on mine looks almost like run-flat. Please excuse my ignorance.

Thanks..

Ignorance on this forum is mandatory :lol:
But yes, I wonder how people have got on with other tyre and non-Porsche wheel choices.
