yellowblue Compact Spare Tire Although the compact spare tire was 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 spare on 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 speeds up to 65 mph (105 km/h) 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. A. Strap B. Bag and Tools Unless you have the plastic "bolt-on" wheel covers, be sure to also store the center cap. When you replace the compact spare with a full-size tire, replace the bolt-on wheel covers and the center cap. Tighten them "hand tight" over the wheel nuts, using the folding wrench. C. Jack 5-31
