WHEEL & TIRE SPECIFICATIONS
TIRE REPLACEMENT
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for wear and
correct inflation pressure. Chrysler strongly recommends that you use
tires equivalent to the originals in quality and performance when
replacement is needed. Failure to use equivalent replacement tires may
adversely affect the safety, handling and ride of your vehicle. We
recommend that you contact your original equipment tire dealer on any
questions you may have on tire specifications or capability.
