Wow
that is one super tidy garage. Loving that tyre rack. By the way how many alloys does one man need? 
Why thank you...
In answer to your question...
4 x 8.5"x19" VW Racing wheels with 225/35/19 tyres.
4 x 8.5"x19" VW Racing wheels spare.
4 x 8.0"x18" BBS CH025 wheels with 225/40/18 winter tyres.
4 x 8.0"x18" BBS CH025 wheels spare.
4 x 7.5x18" VW Monza Shadows with 225/40/18 tyres.
Obviously, one set of tyred wheels will be on the car.
Then theres:
4 x 7"x16" BBS RXIIs with Toyo T1Rs on.
8 x 7"x16" BBS RXIIs spare.
4 x 7"x16" BBS RXIIs with Toyo T1-S on, on my old Mk3.
Then there's an odd 6.5"x16" BBS RXII.
An odd space saver from the Mk3
4 x 6"x15" New Fabia wheels and tyres (actually mothers, whilst she has her winter wheels/tyres on)
And soon, 4 x 6.5"x16" with winter tyres OR 7"x17" VW Classix with summer tyres on, from my old mans Mk5 TDI170.
I think there's an odd Audi A2 wheel up in the garage loft too...
Hmm...that's it. I think.
