Con 1ct 5 Tirt Don't use your compact spareon other vehicles. And don't mix your compact sparetire or wheel with other wheels or tires. They won't fit. Keep your spare tire and its wheel together. Although the compact spare tirewas fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spareon your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at posted speed limits for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it's best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.

NOTICE: When the compact spare is installed, don't take your vehicle through an automatic car wash with guide rails. The compactspare can get caught on the rails. That can damage the tire and wheel, and maybe other parts your vehicle. of
