19" tires and sport rims

Some premiums are coming in with the sport rims. How will the 19" tires and sport rims effect the ride of the non-sport cars??

You'll give up some ride comfort. You will have a smaller/shorter, stiffer sidewall that won't absorb bumps as well. Best bet is to test drive both before you decide.

What's the advantage to having them?

Well when the wheel is larger, there is more tire on the ground since the diameter of the rim is larger. This will increase handling characteristics.

That's a real insightful answer. Check with your secret sources and come back with something real, not "bigger is better."

Also the sport tires are summer only which will give you superior grip in dry weather compared to all seasons....

The Q50 comes with 17" standard, so this isn't a good comparison, however, based on this video I don't see why anyone would want the 19's other than they look better.

It's the best discussion I have seen so far on the tradeoffs with tire size even if the size of the smaller tire is different.

Yes, it is, a lot detailed for a driver to make a educated decision. Most of people I know there are drivers go for 22" but that's just what they like and like I said earlier for these guys "Bigger is better". ;)

I have 3 Infiniti's that have 18, 19 & 20 inch rims, the biggest difference is the ride and handling that I can feel at freeway speeds. I prefer 19 as it's best of both worlds (between 18 and 20).

Here's the scoop with none of the poop:

Tires with shorter sidewalls (distance between the edge of the rim and the outer circumference of the tire) ride stiffer but flex less. During spirited driving, like high speed slalom maneuvers, the less flex the tire exhibits (side to side), the more controlled the ride is. Hard cornering also benefits from low profile tires.

With the common overall size of the tire, a 15 or 16" rim would provide a very soft, yet ridiculous ride, with none of the sportiness we've come to expect. It would squirm and feel sketchy in slaloms. Bring this idea into the real world, and you're dodging a row of suddenly stopped cars in your lane. You have less than a second to jump into an open lane and brake safely. A low profile tire gives you the control and confidence to pull this off without skidding or weaving; you can just safely dart into the open lane and keep going with a quick left-right on the wheel and a stab on the gas.

I've dodged many accidents in my life, and I have really formed a bond with my current car as a result. I know what it will do when things happen fast, in any weather, as long as I react properly. To me that's one of the most important aspects of a car, because honestly, you are trusting it with your life. And that trust begins, quite literally, where the rubber meets the road.

TL;DR version: short sidewalls give you more precise control at the expense of ride comfort.

So where's a happy medium? 18?

Exactly 18's are best of both worlds have 19's on my coupe and 18's on the sedan and in direct comparison my sedan is much more compliant and still gives that bite of the 19's....

It depends on overall tire size and suspension tuning. BMW is really, really good at hiding low profile tires with their suspension tuning. Porsche is too. Supposedly the Q50 feels good on 19's but I can't vouch for that.

18's should be a happy medium because these cars were designed for 17+ in my opinion. I wish they'd make them wider/deeper though because that would mean a larger contact patch on the pavement, which is equally important. The coupes get offset sizes like this with larger tires in the rear and I think the GT-R does also. The only (and it's a big one) drawback to this is you can't rotate your tires in this configuration. If you get symmetrical (non-directional) tires, you can rotate them left to right but not the normal cross pattern (front left to rear right, etc.).
