What size tires can I put on my 2003 Jeep Cherokee Overland?

Question

Don't want to make any other modifications

Answer 1

A stock Cherokee or Grand Cherokee, which I think is the Overland model, will fit a 245/70/16 or 235/75/16 which is about a 30"-31 " tire. Any bigger and you WILL run the tires off road.

Suspension Modifications
Body Lifts are not available.
Fender Trimming

30" No lift required - however small lifts may increase clearances & articulation N/A Some minor fender trimming may be required if rubbing is a problem with wider tires
31" 3" lifts are possible, 4" lifts would be better for trail use. N/A Trimming may be required with wider than stock tires
32" - 33" A 5" or larger lift is required. N/A Some trimming is required
33"-35" A 6" or larger suspension lift is required N/A Serious trimming may be required

Answer 2

They stopped making the Cherokee in 2001. It was replaced by the Liberty.

I have a 93 Cherokee. 9.5x30 will fit but will rub slightly at the limits.

To see all that fits, look at "JP Magazine" on line and click the "what fits" article.
