Anyone actually doing this? The only problem I would see is that the Mazda3 rim has a 52.5 offset and the CX-7 rims have a 50 offset. the Mazda3 rims/tires would POSSIBLY rub when put on the CX-7. If anyone is doing this, and there is no rubbing, it would obviously alleviate my concern. Don't want to invest in the wheels, mounting etc only to find that they will rub. Thanks in advance.
