tire size

what size tires can i fit with a 3in suspension lift on a 97 dodge dakota slt 4x4 5.2 motor

My 2010 Dakota came with 265/60 x 18 tires and wheels. There aren't as many tires made in that size as there is with 17" rims. I did look at a the tire size calculator and found 245/70 18" are about an inch taller and a little narrower. Anyone running 245/70 18 tires? I thought...
