Hi Guys quick question.
Is there any other vehical whos rims will fit the multi.

I don't think so. After trying a few other FIAT wheels, I eventually managed to get a full-size Multi wheel off ebay. It fits fine where the skinny wheel lived.

When I got my car it had non-standard 16" wheels on. I discovered that some wheels only had 3 wheel bolts on them and the bolts were forced on.
So I had to buy spacers to stop the wheels rubbing on the bodywork and spigot rings to make the wheels fit the hub and wobbly bolts to hold the wheels on!!! It's alot of messing around.
I would look for Fiat wheels If I were you.
