Tire maintenance - Trailer towing If you anticipate towing a trailer, you should see any tire dealer for advice concerning the correct size of tire and pressures. Tire size and pressures will depend upon the type and size of trailer and hitch used, but in no case must the maximum cold inflation pressure of tire load rating be exceeded. Check the tire placard and the owner’s manual supplied by the manufacturer of your vehicle for further recommendations on trailer towing. Tire maintenance / CHECK HOW YOUR TIRES ARE WEARING AT LEAST ONCE EACH MONTH If your tires are wearing unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread, or if you detect excessive vibration, your vehicle may be out of alignment or balance. These conditions not only shorten the life of your tires but adversely affect the handling characteristics of your vehicle, which could be dangerous. If you detect irregular wear or vibration, have your alignment and balance checked immediately. Tire maintenance / HAZARDS Objects in the road, such as potholes, glass, metal, rocks, wood, debris and the like, can damage a tire and should be safely avoided. Unavoidable contact with such objects should prompt a thorough tire inspection.Anytime you see any damage to your tires or wheels, replace with the spare at once and immediately visit any Nokian tire retailer. Tire maintenance / IMPACT DAMAGE A tire impacted by a road hazard (curb, pothole, debris) may be damaged but not have visible signs of damage on its surface. A tire damaged by an impact may sustain a sudden failure a day, week, or even months later. You may not recall hitting an object that damaged or injured your tires. Air loss, unusual tire wear, localized wear or vibrations can also be signs of internal tire damage. If you suspect any damage to your tire or wheel from an impact with a curb, pothole, debris on the road or any other road hazard, or if you feel or hear any unusual vibration, replace with a properly inflated spare at once and immediately visit any qualified tire technician. Tire maintenance / TIRE SPINNING Tire spinning is dangerous. Excessive spinning can cause a tire to explode. Avoid tire spinning. The centrifugal forces created by a rapidly spinning tire can cause an explosion by tearing the tire apart. These forces act on the complete tire structure and can be of such magnitude as to break beads as well as rupturing the entire carcass. When stuck on ice, snow, mud, or wet grass, etc., the vehicle should be rocked gently (alternately using forward and reverse gears) with the least amount of wheel spinning. DO NOT exceed 35 mph as indicated on the speedometer. Never allow anyone to stand near or directly ahead of or behind the spinning tire. Do not spin if a drive wheel is off the ground. Serious personal injury or death can result from the explosion of a spinning tire.
