Staggered wheel sizes necessary to match brands

[smithm7]

have a 2007 G35 4dr Sport. The OEM tires are 225/50/18 in the front, and 245/45/18 in the rear. I am having a little bit of difficulty finding options for matching sets for the tires. i was wondering if I could use different manufactures for the front set from the rear. For example, Bridgestone in the front, and Toyo in the rear? In addition, what about same manufacture but different style? For example, Goodyear LS-2 in the front, and Goodyear Eagle F1 in the rear. Your help is appreciated.

Should be fine. Different brands/models can be sized slightly different, but not enough to notice.

First I'd noticed that any sedans had staggered setup.

You should be OK. If you plan on taking the car to the track, you may notice that the tires have different handling characteristics, but normal driving should be fine.

also, be sure to check out the wheels/tires forum.
