How it hasbeen used or how far it has beendriven may be unknown. It couldfail suddenly and cause a crash.When replacing wheels, use anew GM original equipmentwheel.Tyre ChainsUse tyre chains or other tractiondevices only when necessary.Use only 6 mm traction cables thatmeet or exceed SAE Class “S”requirements and that are thecorrect size for 275/35R18 (RWD)or P245/40R18 (AWD) tyres. Installthem on the rear tyres only, astightly as possible with the endssecurely fastened.{ CautionDo not install traction devices onthe front tyres.Drive slowly and follow the cablemanufacturer's instructions. If thecables are contacting the vehicle,stop and retighten them. If thecontact continues, slow down until itstops.{ CautionTo help avoid damage to thevehicle, drive slowly, do not spinthe wheels, and readjust orremove the device if it contactsthe vehicle.If a Tyre Goes FlatIt is unusual for a tyre to blow outwhile driving, especially if the tyresare maintained properly. If air goesout of a tyre, it is much more likelyto leak out slowly. See Tyres onpage 10-33 for additionalinformation. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:If a front tyre fails, the flat tyrecreates 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.
