Usechains that are the proper size forthe tires. Install them on the tiresof the rear axle. Don't use chainson the tires of the front axle.Tighten them as tightly aspossible with the ends securelyfastened. Drive slowly and followthe chain manufacturer'sinstructions. If the chains contactthe vehicle, stop and retightenthem. If the contact continues,slow down until it stops. Drivingtoo fast or spinning the wheelswith chains on will damage thevehicle.If a Tire Goes FlatIt is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. If air goesout of a tire, it is much more likely toleak out slowly. See Tires onpage 10-40 for additionalinformation. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.A rear blowout, particularly on acurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.The vehicle has no spare tire, notire changing equipment, and noplace to store a tire.If the vehicle has run-flat tires, thereis no need to stop on the side of theroad to change a flat tire. SeeRun-Flat Tires on page 10-42.
