I've decided to put 19's on my Z, however, I can't decide whether to go with 9 inch wide tires in the front and 10's in the back or 9's all the way around...any suggestions?

Any pics of both would be great!

Thanks!

 

i have 20x9 in front and 20x10 in the rear and the grip for launching is very good so id say to do 20x10's too but then again idk how good the grip is for the 20x9's soo.., but if you are planning on doing a bigger lip rim then do 9's and 10's.

 

You might find it easier to figure out your tire sizes and back into your rim widths.

Considerations:
Are you looking to keep the stock diameter stagger?
How wide do you plan to go at each end?
How well will these sizes fit on your rims of choice and will they look the way you want them to, ie stretched, squared etc.
Will your combo meet your performance goals?
