I have a 1998 Jeep Grand Cherokee with tires that are 245/70/16's and want to go with newer and perhaps higher numbered rims. Is there a chart that would show what sizes I can use and bolt compatability? Thx,
In all honesty I would go down a size in wheels, 15s will be cheaper, give you more options, and will ride better. But if you are going for the mall crawler look, then find a tire conversion chart to covert it for you a 245/70/16 is 9.6" wide, and 29.5" tall. 245 is metric so to convert it inches divide by 25.4, then the (70) is the sidewall ratio. (245/25.4)=(?x.70)=(?x2)=(?+16). x2 to account of both side walls top and bottom and 16" to account for you wheel size.

However a 16" rim can also be good, especially if you can find a load C tire for it. Dean makes the Dean SXT MT in 265/75R16 load C. That's a good mild hybrid tread, or could be called an aggressive AT. There are also some other tires in 265/75R16 (32 X 10.5 R16).
The only R17 worth running (IMO) are the BFG MT that some stock on JK Rubis. Those are (I think) 32 X 10.5 R17, though they are described by some metric size I can't remember.
