Yes. The 15 at the end tells you the rim size.
Look in any local buy and sell shopper in your area for tires/wheels. Used rims are just as good as new and can be very cheap.
15 rims are extremely common (the most common rim size used). Make sure you get the chevy bolt pattern (5 bolts). Good luck!
All that being said, why are you looking for new rims? Want an upgrade to something snazzier? Looking to replace damaged rims? Some other reason? I can help with those if you are more specific.
