There is no quick way to answer this question considering how whole books and classes are dedicated to this material :laugh: but I will give it a shot...From my experience, there is no single "optimal" set up for both track AND everyday. Either side of the spectrum will have negatives for the other...plus wheel/tire is only one part of the equation.
To answer your question, ceteris paribus...for track you want a lighter/smaller diameter wheel with a wider softer compound rubber. This allows for better feel, response, braking, etc. However, light wheels don't stand up to potholes, softer rubber neither lasts long or meant for adverse weather, and wider set ups tramline more. On the flip side, sturdier street wheels have unnecessary unsprung/rotational weight and street rubber has lower grip/handling/heat thresholds. Which is why everyone whose bank account don't look like a phone number has 2 dedicated sets for street and track. Obviously, non of this matters if you can bankroll top of the line HRE, BBS or Carbon Revolution wheels and mount new tires every month :rofl:
It also all depends on your suspension set up and driving skill...I met enough people that immediately think they need st00pid wide and/or sticky set up when they can barely out-drive a stock one. Before spending any money, I would advise running your truck as is. Get comfortable and max out its current handling limits and modify it accordingly from there. I would also recommend the follow two books; they contain a lot of great driving technique and suspension geometry info.
Anyway, that's my two cents....Disclaimer, I am not professional racing driver and I have not tracked an X-Runner. I am speaking generally from my past experience running motorcycles/cars and taking a weekend driving school here and there :laugh: Good luck.
