Don’t Be Tempted to Drive on Underinflated Tires
There’s a school of thought in snowier locales that underinflated tires are better for driving on snow because the tires will make more contact with the surface. While that’s technically true, it’s never safe to intentionally drive with low tire pressure, even in cold weather.
When tires are underinflated, the sidewalls flex more, resulting in poorer handling. The car won’t turn as responsively and may feel unstable around corners. Underinflated tires also expose the softer sidewall to road imperfections, increasing the risk of punctures.
They can also wear faster, reduce fuel economy and heat up more from friction. That can weaken the tire structure and increase the likelihood of a blowout.
Should You Be Concerned About Over-Inflating Tires in the Winter?
Yes. Overinflating tires can cause premature wear and may increase the risk of blowouts. In winter conditions, it can also reduce traction because less of the tire makes contact with the road — which is especially risky on icy or snowy surfaces.
