On-road handling: Dubs?

Even as the noob-est of noobs, I realize that 20" wheels provoke derision, so I've got my flame suit on. But I also have a serious question:

TireRack shows lots of 20" wheels (with 275/55-20 tires recommended) for JK fitment. Would these lower profile tires improve on-road handling significantly (or, if anyone's tried it, do they)? I realize it's not going to challenge my S2000, but apparently there is room for improvement.

I ask because I'm looking at a 50 mi commute (half on a twisty mountain road) each way several times a week, and I have the necessary garage tools to swap wheels for the weekends in the woods. Thanks, HPH

I don't know about handling, but it'll make the ride a lot stiffer.

2011 RCLB Silverado, It's got the power I need.

Maybe upgrade to performance shocks and stiffer springs I feel like this would help more than low profile tires but don't quote me on that.

Low profile tires are designed for speed/ handling/corners and Independant suspension--

Not solid axles !!

Okay, a two minute primer on handling.... If you have an s2k then use that for the commute!
If you want the jeep to handle well on corners you need to do a few things.
1) maintain a low center of gravity
2) reduce body roll...firmer springs
3) correctly tuned shocks
4) reduce tire flex ... This is accomplished by sidewall, so two options get a tire with stiffer sidewall and inflate, or reduce the sidewall area (low profile)

At the end of the day, if you won't just use a sports car to drive like a sports car...you have to manage your suspension BEFORE spending money on rubber. Tires are the last link in that chain.
Good luck and please, for the sake of your unborn children don't "donk" your jeep

Well, the Jeep is for Colorado, and the S2000 will stay behind in Florida, where it belongs.

Sounds like the Sahara 18s with some kind of A/S tires would be better, then, as a highway setup for a Rubi. Thanks, HPH
