haha, my Reason B. for waiting to purchase my NSX. (I'm not knocking you here by the way, just saying in passing I suppose)
Can't afford some of the stuff it may need, especially when i have to put tires on two other vehicles!
However:
Good luck with your search for tires, maybe check a junk yard for some new arrivals, you might get lucky with the tire sizes.
Note: Sometimes you have to drive. I drove 1999 Civic with Bald All Seasons in one of the hardest winters Ottawa saw in years. Sometimes you have to do it. "Bus" was not an option here because I NEEDED my vehicle. And similarly, I know it was unsafe, but I made it as safe as I could, and in fact i did not run into any issues here. You can drive fine on bald tires, it's just noisy, but if you keep a very safe cushion around you and drive very alertly, you'll be fine. Given my Civic has less than half the power of his NSX, but sometimes you have to do it just to make ends meat.
