2004 Dodge Caravan Owner's Manual - Page 256

256 STARTING AND OPERATING Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. WARNING! Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds may cause tire damage or failure. A tire could explode and injure someone. Do not spin your vehicle's wheels faster than 35 mph (55km/h) when you are stuck. And don't let anyone near a spinning wheel, no matter what the speed. Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced. CAUTION! Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result. Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle's wheels above 35 mph (55 km/h). See the paragraph on Freeing A Stuck Vehicle in Section 6 of this manual.
