I vote staggered 275 rear and 255 front. Here are the advantages: Better Looks, Better Handling, and technically saves you money over 275's all around because 255's for the front are cheaper.

But if you're set on rotating...255 all around.
Out of the box, a stock GT, and the Brembo GT, are set up for the same size contact patch on all 4 corners. If you're looking at the Boss 302, 302 LS, or the GT500, that have matched springs and sway bars for a staggered set up, then it would make sense. If you're going for looks, do staggered, if you're going for better handling with the stock suspension, go squared.

I voted for the 275 since that's what's going on my car tomorrow. :kooky:

I do wonder why everyone goes for the 275/40/18 instead of 275/45/18? From what I can tell, the 45 is closer to the stock 235/50 wheel size and is very close in RPM's so the speedometer will be darn close. Is it just an appearance thing?

IMO the 27 inch stock wheel height is too high, so 26.6" (275/40/18) is the best of both worlds. Bit larger sidewall than the 255/40/19 factory tire for improved compliance and grip with this heavy car and smaller OD than factory for less rotating mass in the tire and less folding over of the sidewall under severe cornering loads with this heavy car.

That's what I was thinking..if you get a good gripping brand of tire, you wont have much tread life anyway, and if the car is aligned properly, wear wont be an issue.
Having said that, I have 275 fronts and 295s back. The only reason I didnt get 315s is that they were on back order. I love the staggered look and I love the look of BIG MEAT in the back...of course Im over 40 and love the old-school muscle cars, so I go for that kind of look. I didnt vote because My vote was "neither"

I ended up buying the AM GT500 Style Black Machined Staggered Nitto package.

The poll was pretty one sided. I did alot of reading and for a daily driver I think this would be best for my situation. The 555's seem to have good treadlife and I like the staggered look.

Now I just have to count down till the day they arrive.

Michelin Pilot Super Sports, 275/40ZR19's all around.

Excellent grip. Stiffer sidewall but still not a harsh ride. Great in wet as well as dry.

Very noticable handling improvement when compared to my stock 245 Pirrellis.

(PS...214_5.0, a staggered setup may look "sick", but it will induce understeer in the Mustang under heavy cornering. If superior handling is what you are after, you want non-staggered...not that the average Joe would notice one way or the other on the street).

You sir, have some bad ass tires. I love Super Sports. I had them on my G37, and it was like driving a totally different car coming from Goodyear RS-A. It was even more pronounced looking at the fact the RS-A is an all season tire.

If if it's placebo... it's just like placebo relationships with doctors... studies show that some people get better over long periods just based on the longer time they spend with their doctor. Have wider tires on back might make people think than can go faster, ok that it certainly looks better. Staggered is good on a fast car. I wouldn't stagger a v6 or anything less if it was a mustang. I don't think the v6 can break the stock tires anyways.. .not sure though.. I saw a tastefully staggered s2000.. he was boosted and needed it though. the higher end bimmers look good if they are the latemodel 5-7 series.

Ok. Ambien kicking in.... night!

Odd size, I guess it may be more common to find a 18" vs a 19"

More grip in the rear, less tramlining in the front. So there is a performance benefit.

Agree, if your not breaking out the rear end, no need, If you have traction issues in the first 3 gears, you may want to look into the staggered setup. I don't get to worried about rotations, as these car shred summer tires in 10-15k miles, if I only get 7k miles out of a rear set and 14k miles out of a front set, rotating seems pointless, just buy a new set for the rears when they wear out, and likewise on the fronts, unless you drive under 5k miles a year, dry rot should not be an issue. I ran on 285/35/19's on all 4 for almost a year, grip was insane, but tramlining the grooves was horrid. After that curb jumped out in front of me I decided to loof for a new set of 255/40/19's(stock) for the front, and left the rear with the 285's. I get all the accel traction from the 285 w/ none of the "sideeffects" of the placebo pill with the 255's up front.

"More grip in the rear, less tramlining in the front. So there is a performance benefit."

Tramlining only really happens on city roads/high ways and is a nuisance more than a performance downgrade.

In terms of handling and braking...a wider matching front tire is going to offer more performance. And if your car came with a square set up and you increase rear grip..you are introducing understeer which by no means is a performance benefit.

Tramlining is a serious nuisance, especially for a DD. I don't know how your roads are where you live, but here they are all grooved severely.


Agree with this, like I stated, the grip with the 285's up front was incredible, would turn and stop like nothing I've ever owned. I'll trade a little understeer tendancy for a little extra "off the line acceleration" and a little better everyday "drivability". I also think the extra weight from the larger tires up front hurt the ride quality a little bit, but that may just be placebo as well.

Did you notice any increased tram lining or another dislikes with this set up?
