236 Tires and wheels i When towing a trailer, inflate the tires to the tire inflation pressure as specified for a fully loaded vehicle. Potential problems associated with underinflated and overinflated tires Underinflated tires G Warning! Operation Example illustration: Tire inflation pressures for all approved, factory equipped tires When a tire size is specified, the tire inflation pressure that follows applies to that particular tire size only. Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Underinflated tires can Rcause excessive and uneven tire wear affect fuel economy affect handling characteristics Radversely Rlead to tire failure from being overheated Radversely Overinflated tires G Warning! Example illustration: Tire inflation pressures for particular tire sizes Some tire inflation pressure labels may only show the rim diameter instead of the entire tire size, e.g. R 18 or 18". The rim diameter is part of the tire size as specified on the tire sidewall (Y page 251). Follow recommended tire inflation pressures. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Overinflated tires can Radversely Rcause Rbe affect handling characteristics uneven tire wear more prone to damage from road hazards affect ride comfort stopping distance Radversely Rincrease Example illustration: Tire inflation pressures specific to rim diameter
