Sorry if these are obvious, but I’ve only ever driven on the same tires year-round. School me, Oppo!
1. So I realize wider is better for track use, but what effect do wider wheels/tires have in daily driving?
2. What about switching back and forth between summer wheels/tires that are an inch wider than winters? Will I have to get an alignment every time I switch back and forth?
3. 4-5 lbs lighter wheels and replacing the run-flats will have a pretty nice impact on ride quality, right?
4. Anything else I should be concerned about?

1. no idea.
2. no idea.
3. Yes.
4. no idea.

In daily driving wider wheels have btter dry handling but shittier in the rain and snow.
You don’t need an alignment just by switching tires. It’s really only needed when replacing suspension parts.
Replacing the run flats will almost certainly give yoy a better ride.

Like dogisabadob said, wider tires will hurt wet traction and snow, but the other thing to worry about is contact with suspension components. When I bought my SHO it had wider tires fitted and they rubbed the strut and the fender well on full Oppo.

I live in the PNW, so shittier in the rain could be an issue. Thanks.

Full Oppo is fine. It’s full FP that’s the problem.

Lighter wheels and no run-flats will definitely improve braking, and to a very much lesser extent, acceleration and gas mileage. You won’t really notice it that much, though. I dropped over 20lbs per wheel and switched form run-flats on my MINI, and day to day I don’t really notice.
Switching back and forth you shouldn’t need to worry about getting an alignment. I use my old wheels as my winter wheels, and I’ve switched back and forth since winter of 2011, and haven’t needed an alignment yet.
With wider tires, you’re going to want to make sure they spread water pretty well, or you’re going to hydroplane more. I’ve been loving how well the Continental ExtremeContact DW does at that, but there are others that do just as well. Check out the review videos on Tirerack to see specific tests, and they’ll mention how well it does in the wet in most of them.

In the snow narrow tires are better. I drive a mighty Chevy Cavalier with over 200,000 kms and swap 225’s for 195’s in the winter.

1. All other things equal, more rubber means less resistance to hydroplaning in wet weather. Wider wheels also mean slightly increased steering effort, but most people don’t notice.
2. You should get an alignment every time you switch a set of wheels, but if it’s recent enough then it’s not a big deal to skip it.
3. You’ll notice the better tires, you won’t notice the difference in wheel weights.
4. Yes, google “scrub radius” and start reading. Fitment issues are easy to deal with (like someone else said, MAKE SURE IT FITS ON THE INSIDE TOO! Nobody wants their wheel rubbing against the shock tower), but you also need to pay attention to how a new set of wheels and tires will affect your scrub radius. Scrub radius isn’t actually a radius measurement (don’t ask me why), but it’s the distance between the center tread of the tire and an imaginary line drawn through the suspension’s A-arms. See the pic below. Unless you are setting the car up for track duty, you should try to preserve the stock scrub radius as best you can to preserve you car’s handling. Generally, increasing scrub radius increases steering effort and quickness, at the cost of making a car very “dart-y” at high speeds. Use a site like willtheyfit.com and make sure that you keep the scrub radius similar to stock. This is the voice of experience, I have a pristine set of wheels and tires sitting in my garage because they offset was too aggressive and increased my Miata’s scrub radius, making the handling very twitchy. Probably fun on the track but not fun on the highway.

Thank you, that was very informative.

No problemo! I found the calculator that I like to use, it’ll compare two sets of tire/wheel combos and let you all the clearance issues you might run into:

Wet traction is only worse in fairly deep standing water. Modern tires have such good profiles that even in the wet wider is better.

Good point. Growing up around a bunch of old school mechanics I’ve picked up some outdated information. Had a set of Goodyear Triple Treads on my Focus. They worked amazing.

Not really surprising if you consider how far tire development has come even in the last 10 years.

Ha-ha, yes it indeed. I probably know more about bias plys at this point.
