For 19x9 +22 front, 19x10 +25 rear

Some has setup
a) 225/40/19 front, 245/40/19 rear
b) 235/35/19 front, 265/35/19 rear
c) 245/35/19 front, 275/35/19 rear

How is the difference between them, and I don't know how to choose?
and how should I interpret the aspect ratio (height to width)?

p.s. I want some setup that fit the VDC system.

 

C is the "standard". Read the post on the 3rd page of the Top 100 Questions thread about "slip light" and tire sizes.

 

I am not going to check and compare these for you. But I suggest you do so: http://www.dakota-truck.net/TIRECALC/tirecalc.html

 

Thanks.
I finally learnt about the VDC system.

But I found that setup a and setup c will probably fit the car.
If I run 19" with setup a (thin tires), will it be not so stable?

 

Members often run a "stretch" tire: width too short for wheel.
or a "fat" tire: tire width too wide for wheel.
But there is very little interest in standard sizing (recommended by tire manufacture). I guess stretch and fat are cool.

 

If we match the circumference of tires to fit the VDC,
The tire width and height should be difference from the 18" OEM ones.

What tire sizes are recommended by tire manufacture?

 

Look at the Track 18/19" v.2 wheel. Nissan puts a 265 mm tire on a 10.0 inch wheel. This is conservative.
