For those wintry times when maximum traction is required for short distances on icy roads, consider keeping a can of Tyre-Grip in your vehicle. Spraying the product, which has been described as “pine sap in a can,” on your tires will, according to the manufacturer, give you up to 300 percent more traction while at the same time preventing snow, mud and gravel from adhering to the tread. Each application will last for up to 50 miles. You can buy a 16-ounce spray can of Tyre-Grip (good for several applications) for $18 from the manufacturer at www.tyre-grip.com.
