What 175/50R16 Is Typically Used For
A low aspect ratio puts less rubber between rim and road. That sharpens steering response at the cost of ride comfort and rim protection.
To find the size your specific vehicle takes, check the placard on the driver-side door jamb or your owner's manual. Fitment depends on model year, trim, brake caliper clearance, wheel offset and suspension setup, so the correct size for your car is the one the manufacturer specifies.
