subject: What You Need To Know About Choosing Car Tyres [print this page] So, to summarize, you need to be aware of the road conditions that you normally drive in, and do not skimp on the cost. Another important factor to remember is to fit the right size tyres for your wheels. The numbers and letters on the tyres sidewall reflect the size of the tyre. In order, the letter(s) dictate the type of vehicle that the tyre is designed for, then the following numbers are the width of the tyre in millimeters, the depth of the sidewall then the tyre type (which will be another letter). After that should be the size of the wheel that the tyre should be fitted to, then the tyres load index, then, finally, the speed rating of the tyre. Check the vehicles owners manual for help if you need it.
