215/50R17 Tire Size

All You Need to Know About 215/50R17 Tires

215/50R17 defines a tire that is 215 mm wide, with a 50% aspect ratio and a 17-inch wheel diameter, producing an overall diameter of ≈25.5 inches and a sidewall height of ≈4.23 inches.

215/50R17 size sits slightly above narrower 50-series fitments like 205/50R17 and below taller 60-series alternatives, positioning it within the mid-25-inch diameter range commonly used on compact and midsize passenger vehicles.

Where P215/50R17 versions are used, they share identical physical dimensions with 215/50R17, but follow passenger tire load standards. 

The P215/50R17 variations are typically manufactured in Standard Load (SL) configurations, while non-P versions (215/50R17) may follow different load rating conventions, meaning matching size does not guarantee identical load capacity.
