Well, I like to have some fun and take hard corners and whatnot so handling is definitely a big factor. If 18's have a drastic difference over the 20's (handling wise) then it's really a no contest for me. Yea, I think the 20's look good.. but that's not the only thing I care about.

To me, all those little imitation fastener heads just clutter the wheel up and draw my eye away from the wheel as a whole to them individually. And no, I don't like the appearance of real multi-piece wheel fastener heads any better even though they have every reason for being visible.

I don't think you'd ever be able to tell the difference between 1-piece and multi-piece wheels of roughly the same weight, and you'd have to be a pretty sensitive person to be able to notice small weight differences.

One piece wheels have one HUGE advantage over 2- or 3-piece wheels . . . they won't ever leak along the joint or around the fasteners.

Ahh I see, look wise it's just not appealing to you. Your point about the one piece wheels makes sense, I'm sure it is going to be a pain to wash those rims. But I personally like the look, and Im leaning back towards the 18's from what I have heard from everyone so far.

............First of all buy what you like best because the performance differences aren't going to matter unless you take your car to the track regularly. As far as everyday driving the biggest concern mentioned by nuke is watching for pot holes because a big one can ruin the tire and rim. What I've noticed between18's and 20's, when I went to 20's with a wider tire I could immediately feel the difference in everyday driving. Response is quicker, tighter and more nimble but the ride is more harsh. The thing with 18's is when you are driving really really hard the tire itself gives you better feedback vs a 20 with lower profile tires. With 20's it's much harder to feel when they are at their limits of adhesion and if you push the limit too far then you can suddenly find yourself in an unexpected drift, but this will be a problem only if you are a very aggressive driver. If 19s were more available and 19" tires weren't way more expensive I would have got 19's instead to have a happy medium. Other than that, just buy what you like best.

I too would be looking at 19's if they were available. I would definitely say I'm an aggressive driver, kinda why I got a Mustang to begin with.. From your experience would you say the 20's handle just as well as your 18's? I get what your saying about a lower profile tire, and it makes sense. But I guess what I'm getting at is would you be able to take a 20 as hard as you would an 18?

I think that depends on the width of your tires in relation to your wheel size. However, just comparing the two (tire sizes being equal) you will feel more nimble in the turns with 18's without a doubt, but you'd be hard pressed to tell the difference in everyday driving.

I can drive harder with the 20s than I did with 17s or 18s. I had the stock 235/50 18s and now have 255/35 20s on my 2011 and my '07 I had the stock 17s with 235 55 17s and I could immediately feel the improvement when I went to 20s, although just tires can have a lot to do with it. The stock tires are all season where as I have max performance summer tires now. Quick hard turns are more tight and crisp. It's not as mushy in high speed slalom type movements or accident avoidance type maneuvers. Long sweeping turns at high speed feel planted and stable but that's where it can bite you until you learn the the limits and get the feel of it.

There should be a noticeable difference in response between 235/50 and 255/35 even if the wheel diameter for both sizes was the same. Particularly if the 255/35's were mounted on wheels an inch wider than what the 235/50's were fitted to.

But at some point, you can have a tire sidewall that's too short for the level of suspension tuning. A short-sidewall tire tends to be more sensitive to the camber that it is actually running at when the car is rolled over in a turn, and will give away more of its potential grip than a tire with a little more sidewall would. There's a trade-off between steering response and camber tolerance going on, and I think somewhere around a 4" sidewall height (taken as one half of the difference between tire OD and rim diameter) is a good place to be.

Truth be told, I wasn't all that crazy about 18" wheels when I got my '08. But I was even less happy with the prospect of 55 profile tires and little in the way of 17" upgrades. It's still a PITA to change wheel/tire combinations that weigh 55 lbs or so.

Exactly what is to be expected, and again particularly true if the wider/lower profile tires are mounted on wider rims appropriate to their size.

The flip side of response being more linear is less warning before it lets go and slides. Easier to drive harder up to just below the point where the driver had better be on his A-game.

I agree with mph07alloy. I have 20's on my 2011 mustang gt and I think the handling improved. Anything bigger would have it looking like garbage. The only knock I have on my 20's is that at highway speeds it does ride a bit rougher than an 18 or 19. However in town you will never feel it. I just feel it fills in the wheel well better than the stock 18's and 19's once you upgrade the suspension and lower it an inch to inch an a half. But ultimately it is up to ones preference.

Exactly, it happened to me once. When I first put 20s on my '07 I thought I was invincible going around a sharp curve and with no warnign, no squeals from the tires, no feeling of the car slipping, BAM next thing I know I'm sideways at 50 mph staring at a big ole Arkansas pine tree. Luckily I recovered it but I learned the disadvantage of the lower profile tire quickly.
