I'm thinking about getting some Yokohama Geolandar A/T II tires for my 2002 SE. The stock tire size is 265/70/16. Looking at the specs for these tires the two sizes seem to be close. The advantage of the 245/75/16 is that tread depth is 4/32" more, although tread width is almost an inch less. Overall diameter and revs per mile are equal.

P265/70R16
Approved Rim 7.0-9.0"
Overall Width 10.9"
Overall Diameter 30.7"
Tread Width 8.3"
Tread Depth 13/32"
Static Radius 13.7"
Revs per Mile 676


LT245/70R16
Approved Rim 6.5-7.5"
Overall Width 9.8"
Overall Diameter 30.8"
Tread Width 7.6"
Tread Depth 17/32"
Static Radius 14.3"
Revs per Mile 679

The extra tread might mean more traction in mud and snow and longer tire wear, but less width may compromise that thought. The slightly narrower tread may improve fuel mileage, but a little more width means better floatation offroad. The stock rim is 16x7 which seems to be better fitted for the 245/75/16. Why didn't Nissan make the stock rim 16x8 for the 265/70/16 stock tire?

Any opinions?
