Staggered vs. Non-Staggered?

What are the advantages of a staggered setup as opposed to equal sizes all around? Is it just for looks, or are there other advantages? I see most people here are utilzing a staggered setup. Thanks.

With the staggered setup, it's just mainly for looks. With equal sizes all around, you have the advantage of rotating the wheels/tires.

BMW puts a staggered setup on the cars stock for certain handling characteristics. They put smaller width front tires on so the car will understeer instead of oversteer. Basically the front tires will slide before the back tires if you enter a turn too fast.

Recovering from understeer is much easier for the average driver (hit the brakes), where as oversteer recovery requires precise throttle control and counter-steering.

Autocrossers or racecar drivers prefer a balanced setup so they can handle the car faster and with more control.

I plan on using a staggered setup just since I like the way it handles now (255 rear tires and 225 front tires)

I'm just wondering would a positive handling characteristic for a staggered setup be that the vehicle is less likely to lose traction while accerlating in a corner because now the back has a bit more traction to add accelerating as well as cornering to the traction circle?

Same would be for trail-braking in a corner, since the back has more traction you can brake a bit harder in a corner before losing the rear end compared to non-staggered setup.

I believe we are taught that the neutral handling characteristic of non-staggered wheel/tires is mostly when the vehicle is neither accelerating nor decelerating in a corner.

thanks guys....I'm still not sure what I should go with. I don't drive my car that hard, and being able to rotate the tires would be nice.

But the wider rubber on the back sure sounds cool too.

Front also has increased grip assuming you're going wider at all four corners.

BMWs are setup to understeer, with a non-staggered but overall wider setup you will get a more neutral balance w/ more grip than before.

You will have more grip in the back, but you will also have more grip in the front.
