Perhaps this is getting off track a bit but...I didn't start it and I think it is pertinent...squared vs staggered is a facinating discussion to me...I'm still trying to decide on summer wheels/rubber.

Increased rolling resistance hasn't been mentioned.

The statement that tramlining is only an issue on city streets and highways is interesting as well...that just happens to be where I drive. Perhaps if I had a car just for a killer road coarse track...

Also interesting, and not yet mentioned, is the Boss and GT500 come with 255/285 f/r...and in 19" wheels/rubber (although I think maybe the new Shelby has 20" rears). Also, most all the performance cars I look at come stock with wider tires in the rear, and the higher end cars will typically have wider tires than we're discussing.

To me, it's not having a staggered setup just to have a staggered setup (real tough to compare the width of the front tires to the rear as low as the car is), it's to get as much rubber in the rear for traction and as much up front for steering as is reasonably possible w/o having the fronts pull me around and without having to take out a 2nd mortage whenever it's time for tires.

Plus, I've read that you can correct the above mentioned potential understeer issues w/your suspension set up.

Also, my state allows studded tires...lot of wear grooves in many of these roads.

As an aside, (for this derail I do apologize but I've already gotten over the guilt) I almost ordered the adjustable Ford Racing suspension pack yesterday. Decided to order a decent floor jack, buffer and Son's 22nd birthday presents first. Best price I've found is at FordSuperCenter.com, $1525 delivered...in fact the guy (sorry, can't recall his name) who's posted here for that site included the pack on their webpage after I'd asked him if he could get it...now I do feel guilty about not ordering it yet...maybe I should use that guilt to justify putting it on plastic...if I get 5 supporters chime in in the next 24 hrs and say 'hell yes', I will.

275's all the way around if you are looking to rotate I bought the new amr wheels with 255's in front and 275's in the rear. I already miss having 275's in the front. as soon as the tires wear, im going to do 275's in the front, and 295's in the rear

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.
Agree on larger rear tires. Certain tires can be rotated from side to side. My car is a DD and I have Michelin Pilot Supersports which can be laterally rotated (315/35/20 rear and 275/35/20 front)

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.
In this context it makes perfect sense, but there does seem to be a big misconception that because certain cars come staggered from the factory, that there is then some performance benefit of it. That simply isnt true

And if you really dont care about cornering and braking aspects of the car and you mainly are looking for more off the line grip, then I can understand just upsizing the rear tires

Am I correct in my understanding that 255/45 are the max width that an 18x8 stock wheel can accommodate, or is a 275/40 doable?

I wouldn't go wider than 255 on a 8" wide wheel.

this suggests the widest tire you should mount to that 8" wheel in a 45 profile is 255mm. In a 40 profile, a 245.

I had 255/45/18 on my stock 18x8 rims that were on my 08GT. Can't help on fitting a 255/40 on a 8" wide rime, I know on the BBP rim my 255/40/19's look slightly stretched on the front 9" wide rim.

In my case it's not that I don't care about them, I sure my car handle it's own on a turning/braking standpoint, as well as straight off the line.

IMO, the worst side effect of being staggered is understeer, and that my friend is easily cured with a jab of the right foot:nogrinner.

They have matching sway bars and springs for the staggered set up. They are optimized for different contact patches front to rear. Both the base and the Brembo GT are tuned from the factory for a square set up. 99% of the people will not notice a difference on the street, but if you do any kind of performance driving it is noticeable. Also, if you know how your car will behave at the limit, in case you do run into an "Oh ****" situation on the street, you will know how your car will behave when you need to take evasive action.

Every once in a while on a heavily grooved road I might get a bit of tramlining, but very minor and not annoying. Last saturday I took a 150 mile trip out into the country with my friend and his 2007 Shelby. We tore up some beautiful twisting mountain roads at rather high speeds. I noticed no tramlining, just the improvement in precision and grip.

I can confirm that they ARE bad-ass tires.
