I have an '06 M roadster, and am looking to put 19-inch wheels and tires on the car. When looking at some of the wheels at Tire Rack, they told me that the "general" offset would be 40-42 in the front, and about 30 in the rear. This would allow for 245/35-19's up front and 275/30-19's in the rear. While I am still going to purchase the tires from tire rack, I have decided to get the Miro M6 replica wheels in the 19-inch size. The offsets for these are only 35 for the front, and my choice of 20, 30, or 40 for the rear. Can you tell me if I used the 35 offset up front, and 30 offset in the rear, I'd still be able to go with the recommended tires sizes above, or would I have to go down to 235's in the front and 265's in the rear, to avoid rubbing?
Thanks...

Please don't put replicas on such a sweet car....just my opinion. Have you looked at what BBS has to offer for your car. Some RGRs or LMs would look sweet.....pricey but so worth it. Again my opinion, but good luck with your search for new rims/tires.

These "replicas" are manufactured by Miro, the same manufacturer that makes the factory wheel. They just don't COST as much. I still am looking for an answer. On my '06M Roadster, what offset do I need to be able to run 245/35-19 in front and 275/30-19 in the rear, without modifying my fenders?
Can ANYONE help?
