Offset help?

2013Zsport · 02-23-2014, 05:56 PM

Hmmm. That's different from what I measured on pre 2013 models, maybe they changed something on the front. Didi you lay a thin flat object across the diameter of the wheel and measured from that?

Yes, I used a level. That's the only thing I can think of is that maybe Nissan changed the offsets on the 13s wheels.

What do you think I should run for tires? Drop it down a size on F & B?

The nice thing about rimsNtires.com is that it shows how far the tires will stick out so you can play around with the tire width. You also got to make sure that the overall diameters are not too different rear to front.

Let us know how it works out.

I will! Thanks again for your help!

Make sure you don't go 35 series front and 30 series rear that will lead to this since the front tires overall diameter will be larger than the rear

BRAKE, ABS, VDC OFF, SLIP light on.What do I do?

I would go 20x9.5 (+20) with 255-30-20 front and 20x10.5 (+15) with 285-30-20 rear if I was choosing this wheel

Not questioning just trying to learn.

How come the stock wheels are 40 in the front and 35 in the back? Those are different, should they not cause a similar issue?

Is it because you want to keep the rear and front diameters similar? Aren't the numbers I ran within reasonable limit?

All depends on the sizing, VDC is generally happy if you can maintain stagger with the fronts being less than 1% greater than the rears

The stock setup of 245-40-19 and 275-35-19 rear is .5% larger in the front which will not be detected by the VDC/TCS

255-35-20 & 285-30-20 is 1.1% larger in front which could possibly risk the VDC/TCS going off with

Best way to be safe is to use a tire size calculator:
