How Can I Tell My Car’s Tire Size?
Not sure how to tell which tires your vehicle might need? Let St. Lucie Battery and Tire's staff of knowledgeable technicians assist with all tire shopping needs! Here's some quick facts to get you started with tire buying in Vero Beach, FL.
There’s information embossed on the sidewalls of your tires, but if you don’t know what it means, it won’t do you much good. Let’s break it down:
A typical tire size stamp might read as P225/50R16 91S.
- P-- denotes “P-Metric” size, common on almost all vehicles as an industry-standard unit of measurement
- 225-- indicates that the tire’s cross-section (or “section width) is 225 millimeters, from widest point of outer sidewall to widest point of inner sidewall
- 50-- denotes aspect ratio, meaning that the sidewall height, from rim to tread, is 50 percent of the section width. In other words, the lower the number, the lower the sidewall...and the higher number, the taller the sidewalls
- R-- radial construction
- 16-- 16” rim size
It might be tempting to deviate from standard factory sizes, but remember this -- your car was engineered for a given tire size. That means that handling, steering response and braking performance were all calibrated for that tire size and design, and changing tire sizes can have an adverse affect on all those aspects of overall performance. What’s more, changing tire sizes can throw off speedometer readings, especially if you opt for aftermarket rims that are larger (taller) than the ones from the factory.
