Right now I have a 2005 G35 Coupe with the 19s.
Planning on getting some winter tires this weekend.

Just a question though, if I go from 19s to 17s, will my car drop drastically?
I'm asking because I don't want to have trouble going up my driveway and hitting the curb of my driveway. I'd say my driveway curb is a good 3 to 4 inches in height.

Just don't want to get screwed after I buy my winter tires and wheels.

Thanks

 

Ah you don't run the same aspect ratios!

If your oem 19 tire is 225-40-19, then for a 17, you run a 225-50-17 or similar. If you going to a tire store, they will be able to help you out.

 

I have a 2006 G35 coupe 6mt with the 19's. I was curious whether you could go to 17's or if the brakes are too big.

 

17s should fit. They are the standard size wheel on the base model.
