I have an 06 325i. The car is great, but the tires are trash. At 21K miles, I will have to replace them. The tread near its limits, and the road noise is unbearable. I will buy regular tires, but I will not have a spare tire. I am thinking of buying a donut from another manufacturer. The bolt pattern for my BMW is 5x120. Does anyone know where I can get a donut with that bolt pattern? Of course, I will have a couple of cans of tire inflator (along with a jack and wrench) in the trunk, but I would also like to have the relative security of having an actual "spare" tire. If any of you have replaced your RFT's and are VERY happy with the replacement over 20K to 30K miles, I would also welcome your suggestions.
