Tire Stagger
 

Is there a general rule or a ratio on size difference between rear and front tires?

TIA

What do u mean? How wide or the size of the wheels?

the diameters must be within 3% of each other (i think thats the right number) or else the electronics will hate you

I know on my audi s5, I have 255/35R19. If I go 20" wheels than I need to decrease my side wall height to 30. If u go 21" wheels than 25.
But this is what I read.

I think the OP is asking if there is a preferred proportion between width of the front and width of the back tires.
NISMO stock tires are 245/285, or the fronts are ~86% as wide as the rears.
Is there a point beyond which it adversely effects handling?

More front tires, better and quicker turn in, but easier for the back to step out

So, I would surmise that more back tire would make the car tend to push more, or understeer?

Yes and more traction off the line

I'm running 285/35-19 front and 345/30-19 rear. And track the car. :driving:

Yes, this is my basic question. Thank you all so far.

I was wondering about the widths. Sorry for the confusion.

for PERFORMANCE? you should read the track forum extensively

but in summary, the preference is little or no stagger, 275 or 285 square for naturally aspirated cars

add more power and the equation changes

Ok, so the reason I'm asking is simple. I need two new tires for the rear but my fronts are fine. (will get measurements later).

Im stock wheels on 17 NISMO. 285/245. If I went with 295 on Rears, keeping fronts at 245, what are the the consequences, if any?

That's why I was asking for a ratio or standard formula. I know what the ratio is right now by doing simple math. However, does that formulation work the same way as I start going to slightly larger sizes? I'm guessing going to 295/255 eventually wont make a difference?

I will stick with the Bridgestone S001 for now and will change brand on all 4's when time comes.

Long as you are within the 3% of height difference. If you are going with 245/40-19, 295/30-19, You're close at 2.7% Once you get to the 3% difference. Your dash lights will light up.

If u go slightly wider like he wants to 285 to 295, that should be fine. Now if he goes any wider than 295 than he would need wider wheels.
At least that's what I've read.
I have 255 all around stock. Going to 265 is good. But going 275 is not.
