Since your profile only shows US Male, it's hard to tell more about you or the car you have.
So when you say "once in a while", does that mean you want to drive the car at other times with different wheel/tires?
Also, how much power do you have now or plans for in the near future?
What kind of track do you plan to run?
What tires?
What are the street plans?
The answers relate directly to your question. It's not just a simple yes or no.

I was informed that I needed to provide more information. My car isn't a commuter car. Currently 510 whp with some mods. Adding a msd ported intake and 102 Nick Williams throttle body in two weeks. Might get me to around 550 whp. I have C7 ZO6 wheels on her. Would like to find some 17x11 36mm wheels to mount some 315 35 17 drag radials on for a few 1/4 mile runs once maybe twice a month. Obviously the 17s won't have tire sensors. How will this effect the computer. Will I be able to drive to the track without any issues? And if I choose to leave them on for some around town driving will the computer cooperate? Should I go with a larger wheel that will accept tire monitors. Obviously I'm new to the Corvette world. It's an 2008 with 10k miles. Thank you in advance.

Thanks for filling in the blanks. You could run 275's at your power level, since you'll still be under the rough 575 whp that seems to be the switching point to go to 315's. However 315's will work fine, but require a little lower pressure to hook. Either one will work better, on 9.5 x 17 wheels, such as C5 Z06 fronts, C4 A-molds, C4 sawblades, or C4 salad spinners in order of increasing weight, age, and decreasing price. Those are all Corvette wheels with 56 offset and will fit on your Z06. Generally, the C5 Z06 front wheels are the most often used. You won't need TPS for short term/distance driving, but the DIC will show flats or XX and a light will illuminate. One quick push of the TC button will kill the light. If you drive about 20 miles without shutting down, you'll get another warning that can be cancelled by tapping one of the buttons on the right side of the dash. Hoosiers will hook well at the track when heated and are lighter than other brands, but will wear faster on the street. (~3-4K miles?) BTW, be sure to use metal valve stems.

Thanks for all the much needed information. Question: If I go with the smaller width rims as you suggested will I be able to run 315s on them or be limited to the 275s. My tuner seems to think we will be closer to 600 whp with the ported intake and throttle body. From what I've read a 40 hp gain is more likely. And he told me that we will have squeezed just about all the HP out of it while keeping it naturally aspirated. He says supercharger is safe if you keep the boost low. 5 pounds of boost. Thank you.

Both tire sizes fit on 9.0 to 11.0 wheels and they are within .1" diameter of each other. The difference is in tread width and weight. You'd need to run lower pressure in the 315's to take advantage of the width on the launch. The disadvantage is the extra rotational weight and frictional drag down track. It sounds like you'll be in that middle zone of 550-600whp where you won't know which tire works best until you try them both. Personally, I'd try the 275's first, since if they don't work well, the used market is much larger when you'd be selling.

MT's are 30#, which is OK if you mostly drive on the street, since all that extra weight is on the tread. If you want to launch hard and not be concerned with rotational weight liabilities, then Hoosiers work for the track. All the wheels I mentioned are 9.5" and Hoosier supports both tire sizes on wheels in the 9.0 to 11.0 range. You can use wider wheels if you want, but again, you'll pay a rotational weight penalty plus extra bucks. Wider wheels than necessary don't let the sidewalls flex as much at the launch.
