Next I will be fitting some 235\85\16 the tires that I have looked at are 31.8 inches tall which is considers a 32 inch ...........I currently run 30.7 and considered a 31 inch tire from online tire stores.
This tire would be another inch in height but cut in half due to center circumference I would gain a half an inch in ride Height clearance that would put me close to 16 inches of clearance. I currently clear 15.25 inches of clearance.
This will be the tallest tire that will be able to fit under the PATs that are lifted. a 33 is to big for the back wheelwell it will rub all the way around modding the wheelwell slightly would work.... Gas mileage to definitely go down with a 33.
Im averaging 20-21 mpg total with my current lift and tire setup, Im all highway 25 miles one way I do drive 80mph to and from work so I could improve MPGs but Im not worried about it.
