172 STARTING AND OPERATING Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle's wheels above 35 mph (55 km/h). See the paragraph on Freeing A Stuck Vehicle in Section 6 of this manual. Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced. WARNING! Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds may cause tire damage or failure. A tire could explode and injure someone. Do not spin your vehicle's wheels faster than 35 mph (55 km/h) when you are stuck. And don't let anyone near a spinning wheel, no matter what the speed. These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the tread is worn to the tread wear indicators, the tire should be replaced. Many states have laws requiring tire replacement at this point.
