Operation TireSafe

Worn tires can't grip the road well and can be extremely hazardous. Are your tires winter ready? Check out these tips.

"All-Season" Isn't Best for Every Season

When it comes to snow or ice on the ground, all-season tires simply don't compare to winter tires. Consider investing in safety by having a set of winter tires so you're prepared for any winter conditions that Colorado throws at you.

Tire Stopping Distance

If a Traction Law is called, your all-season tires might not make the cut. If you don't have the proper equipment during a Traction Law, you could face fines as low as $130 or as high as $650.

Check Your Tread with the Quarter Test

How do you know if you need new tires? The Quarter Test is a quick and easy way to assess if your tires meet the minimum tread depth (one-eighth-inch) during a Traction Law.

  • Insert a quarter into the tire tread upside down, with Washington's head going in first.
  • If the top of George's head is covered by the tread, your tires are OK. Do this test at multiple points around each tire.
  • If the top of his head is visible at any point around the tire, your tires won't meet the Traction Law minimum, and you should consider new tires.
