1998-2001

The stock rim size is 15 inch.
If the radio is not working on a 1998 Jeep Cherokee Sport it might be a blown fuse. Try the CD player to see if that works. If the CD player works then it might be an antenna problem.
Most parts will not.
Have a shop check the AC system pressure
The factory radio does not have an aux Jack.
My answer 1998. My cherokee sport had 275000 miles on it original motor and drive train. Would still be on the road today had an idiot not rearended it and caused $4000 damage.
