Tire Ch-'ns If your vehicle has P235/75R15, P235ROR15, P235/55RI 6 or 31x10.50R15LT/C size tires, don't use tire chains. They can damage your vehicle because there's not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured a crash. in Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer's instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it's contacting your vehicle, and don't spin your wheels. If you do find traction devices that will fit, install them on the rear tires. Nofice: If your vehicle has a tire size other than P235/75R15, P235nOR15, P235/55R16 or 31x10.50R15LT/C, use tire chains onlywhere legal and only when you must. Use only SAE Class "S" type chains thatare the proper size for your tires. Install them on the drive axle tires (four-wheel-drive vehicles can use chains on both axles) and tighten themas tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer's instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle. If a Tire Goes Flat It's unusual for a tire to "blow out'' while you're driving, especially if you maintain your tires properly. If air goes out of a tire, it's much more likely to leak out slowly. But if you should ever have a "blowout", here are a few tips about what to expect and whatto do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. 5-72
