I've run 245-45-16s on All four corners with no problems on the stock rims.
We're currently running 245-50-16s on the back, and when those run out of tread, we'll be putting 255-50-16s out back and 245-45-16s up front.
255s in the back on a stock rim isn't the greatest handling tire, but it's about as stable as the mkiv guys that wrap 315-35-17s around the stock mkiv rims. I.E. they hook up.

I run 245/50-16's on my stock sawblades. This is my second set, the first set wore evenly with no signs of scallops or any other deformities all the way thru the 30k mile life of the tire and I never even had to rotate them. I run Goodyear Eagle F1' and have put in a link to the Goodyear site showing the Approved rim widths of a 245/50-16 Goodyear. I have no problem hooking up and feel a lot of folks who have hook up problems are running cheaper tires. I fell Goodyear Eagle F1's have a tread pattern that is not only awesome in the rain but also sticky when it's dry. You can check out any tires abilities at Tirerack.com and read thru the reviews of the folks who buy them. I did and that's how I ended up buying the F1's

I'm sure I haven’t got much torque compared to many of you since I'm running a stock N/A, I’m more into the handling of a car. If you are concerned about my comment about traction, go to tirerack.com and read up on your current tires from people with all kinds of cars and mods, then read up on the F1 reviews from folks with all kinds of cars and mods and I think you’ll agree this tread pattern does lend itself to traction in dry and wet. Myself I’m far more concerned how my tires will handle when it's wet than dry since any cheapy tire handles decent when it's dry. If you have ever been cruising along at the speed limit and started doing 360's in the rain on the freeway here in socal I’m sure you can appreciate my views on tires. I've driven mine everyday to and from work for the last 4 years and have put 55k miles on it. Not bad for a 3k stock supra with 176k miles on it.

i have ran 245 on all 4 coners and i did not liek them much and then ran the 225 and was much happyer

now i run 235 45 17 in the front and 255 40 17 in the rear 7.5 rim on all 4 coners

going any thing over 245 will not lead to better traction on stock rim 7 inc will just not cut it

I will vouch for the F1 GS-D3's that suprageezer is talking about. Bought a pair of them (275's, from a camaro buddy) for my rear mk4 wheels and they had about half the tread life still on them. They had awesome grip while they still had tread on them (wore them out pretty quick once the 60 trim, FFI and big FMIC and 18psi came around lol) but I loved them. They weren't the greatest handling tire, you could feel the rear a little loser than the front from the less than ideal sidewalls on the F1's. But strait line traction more than made up for it. I'm seriuosly considering getting another set, torn between these and drag radials...

if you go any wider than 225, you must decrease the profile accordingly.

as Nick said, a 245/50 will be taller than a 225/50 by a bit. not quite an inch, though
when you purchase tires, talk to the salesman. tell him what you want to do, he should be able to point you in the right direction.

as far as i can see, a 225/50 has a 112.5mm sidewall
where a 245/50 would have a 122.5mm sidewall, 10mm taller overall
the correct aspect ratio would be 245/45, that would give you a 110.25mm sidewall

now if you wanted to put a 255 on the car, the correct profile is 255/45r16

for reference: 225/50r16, sidewall profile is 112.5mm
if you wanted a 255/45r16, sidewall profile is 114.75

the problem with tires, though, is they vary. like shoes, or pants.
so, pick tires at your own risk. nothing bad will happen, they may just not look as right as your friends if you choose a different tire.

good luck to you, however.
though i doubt you will need it :D


hope my rambling helped.....
