16" X 8" Factory Stock Tires 245 50 ZR 16 Note: (Tires Should be "ZR" Rated)
Yes, it matters. Preferably each axle should have the same tires EXACTLY.
A ''Z'' tire means that the top speed rating of the tire is not designated, and you must consult the manufacturer to obtain the rating. A ''W (ZR)'' tire's top speed rating is 270 km/h or 168MPH. A ''Y (ZR)'' tire's top speed rating is 300 km/h or 186 MPH. A ''ZR'' tire is rated at top speed of 300 km/h or 186 MPH, AND ABOVE. No, ''Z'' tires, and ''ZR'' tires are not the same.
One can easily purchase a MG ZR car at a website called SmartAutoSavings or AutoTrader. Now a days it is easy to find any car you want through the internet.
I use Michelon Pilot Sport 2's on mine. 295 ZR-18s in back and 285 ZR-18 up front. They really stick.
Auto Trader's website is one place online where a MG ZR can be found for sale. Exchange & Mart's website and Car Site's website also have MG ZR's for sale.
Race car tires are super sticky. And when I say sticky I mean like GOO. A pebble pushed onto the smooth tread will STICK there. These tires are not legal for street use.

Squeak in tires (when turning in particular) could mean low tire pressure, or bald tires.
If by spare tires you mean the temporary spare that is in the trunk, then a car dealership is your best bet. If you mean tires to keep as a back up, the I can recommend Tony's American Car Care Center in Renton. ACCC is a nationwide franchise, so you will be covered if you are travelling.
