What Does Wheel Size Affect?
Every vehicle manufactured is designed with a specific wheel size that is considered optimum for daily driving conditions, economy and performance.
For example, better handling and cornering is usually the result of "plus" size wheels. Also, changes in the circumference of the wheel can affect the calibration of the speedometer, transmission shift points and more.
The Effects of Under or Oversize Wheels
For every vehicle, wheels and tires are a part of the suspension system and any change will affect both the ride and performance.
Smaller wheels will reduce fuel economy and affect steering.
Wildly oversize custom wheels and tires usually require suspension component changes and often result in a bumpy ride.
Choosing The Right Wheel
It's a little more complex than you might think. Just considering bolt patterns, there are currently 17 different lug bolt lug patterns for cars alone. Wheel diameters range from 15" to 22" and "normal" widths range from 6" to over 10". Offsets vary depending on the suspension design and help a wheel "clear" brake assemblies, etc.
For example, a custom aftermarket wheel size for a 2013 Ford Fusion might be 18x8 5-108 45S , which means an 18" wheel diameter, that's 8 inches wide, with a 5-bolt pattern 108mm apart with 45mm of offset with a Silver (S) finish. Recommended tires would be 235/45-18.
