Second this. I have done it in my 90 with 750s on wolf rims, So only slightly smaller. Stacked one on top of each other. But they do wobble around a disconcerting amount while driving!You'll be able to fit them into a 90. It's tight but they'll fit, just stack them upright
That is actually a good idea, even better if we had some wheel nuts for steel wheels. Besides sod's law dictates 5 miles down the road we would get a puncture on the way to collect them.Take your spare off, and hang one of the new ones outside.
Room for at least three more in there!
But then you dont have them acting like a bobble head in the rear view mirror. Where is your sense of fun!Good idea tying them down. Mine moved so much on the journey home that I thought they’d exit through the back door!
