Hi All

Continuing from my other thread,

I may need replacement tyres and looking to refurb the wheels too.

New front tyres, circa £500 + refurb £700 (company i know and used before and know how good they are) = £1200+

If I fitted new rears too, that touching £1900 maybe...

I’ve located a set of freshly refurbed 20” RS wheels with Michelin Latitude Sport 3 tyres and TPMS fitted for just a touch more.

I like the look of the wheels too and i can just get my current wheels refurbed at my leisure then :D

Question
Will there be any discernible ride difference going from 21” to 20” wheels ?

My MacanDS has air suspension if that makes any difference

Cheers

I have 21's for summer and 20's for winter. The 20' are noticeably better in every way, they really are the sweet spot for the Macan.

Agree, had both on air and the 20” gives a far better overall ride. Currently a full set of 21” Michelin’s via Black circle is £910, the rears are actually cheaper than the front.

Comfier on the 20's, cheaper tyres and to be honest I think they look better. The RS Spyders for me is the best looking wheel I've seen in a long time.

I have 20” spyders as winters and 21” for summers, I’m on air in my diesel and I don’t actually notice that much difference, but my winters are Dunlop and summers are Michelin, I think Michelin are the better tyres.

Also, I’ve said it before, Costco sell a full set of 21” Michelin Latitude for £770 fitted. I would use Lepsons for the refurb.

The tread width is the same for both 20" and 21" wheels but the sidewall is taller on the 20" (21": F=265/40, R=295/35; 20": F=265/45, R=295/40). OK, the difference is only 13.25mm on the front and 14.75mm on the rears but it makes the sidewall more pliable which improves the ride. You can probably debate forever how noticeable it is :D

With 20” also considerably less road wheel noise transmitted, especially noticeable if on a concrete motorway surface 😖
