How do I know if my tires need inflating or deflating?

Published 10 December 2015 in

The only accurate way to know if your tires need to be inflated (or deflated) is by measuring the pressure with a reliable and accurate tire pressure gauge.

A common misconception is that a visual check is sufficient to assess tire pressure. Tires can be significantly under or over-inflated by up to 20% and you may not be able to tell just by looking at them.
