15" tires seem to be going the way of 13" tires. Is there a stock 16" wheel that will bolt up to my old XJ?

 

As long as it has a 5x4.5" bolt patter and have at least a 3.5" back space you can use them.

 

I can't find used 15s anywhere that are all the same size. Next week in planning to grab a set of new Wranglers, though.

I'm looking at getting a set of ZJ Limited wheels, they are 16s. Late XJs ('00s and '01s, I believe) had optional 16s as well.

 

Ah. Off to the junkyard, then. Thanks for the info!
