5x114.3 is the bolt pattern. Tires on the stock rims should be like xxx/xx/r15. The 'xxx' is essentially the width, the 'xx' I put in is basically the profile of the tire, the bigger number the higher the profile of tire, and the r15 is basically saying the rim diameter is 15". If you go to discount tire direct or tire rack you should be able to search tires by your car model. Hope that helps.
