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
