Is it possible to fit 205/50/15's on the OEM 15" rims for a just-a-Cooper? It seems a little wide but the tires I want are in that size and I don't really want to buy new rims right now. Also does anyone have any photos of how chunky it will look?

 

They'll be a full inch less in diameter than stock. 205/55/15 would be better,
and although 5.5" wide is on the narrow end of the range of wheel widths for
a 205 tire, it should fit. What tires are you looking at?

 

I see that you are right about the 205/55/15, they would be better and be pretty close to the stock 175/65/15 the car came with. Looking in the 205/55/15 category I would probably go with the Continental ContiExtreme Contact's.



I've also looked into 195/55/15 sized tires as well and thought the Goodyear Eagle GT's would work pretty well.



I have Yokohama Avid TRZ on my car right now and they are horrid, the wobbles really bad at anything over 65mph and and concrete roads with the comb going with the flow of traffic. It's annoying.
