I did not flip the spare mount. It is in stock position and my 30.75" tire juuust fits with zero rubbing. Note: every tire brand varies slightly in size - my Cooper Rugged Treks are 265/60/18 and are 30.75". Other brands may be 30.25 or 30.5." Technically, by definition, they would all be 30.5, but in reality, variability exists.

go to the "what did you do with your d2" sticky thread to see pic of my spare tire clearance with bumper. I posted about 1.5 weeks ago.

 

Like others I've got 245/75/16 wheels, they're falken wildpeak AT3s, they rub just a smudge on the rear bumper but honestly it's nothing. There's no rubbing full lock or anything and I've taken this setup off road a few times and haven't had any issues at all. This is a completely stock set up all original. In my opinion this is the best size tire to get especially if you're riding stock. Plus the gas mileage and acceleration is virtually the same as stock so no worries about having to regear or anything like that.

 

D2's came with two different steering stops, so that affects rubbing at full lock. I am with Alex, I don't really worry about full lock rubbing too much. I pull the steering stops out and throw them away. Mostly run street tires on the street and it helps with the turning radius. Off-road, stay conscious of the size and don't go full lock, especially in extended articulation situations.

 

I'm running BFG AT LT265/65R18 LRE tires. My vehicle is setup for overlanding: Tent, Fridge, Awning, Winch and other related gear (tools, recovery gear, cooking gear etc.) so it's always carrying extra weight. I am running 1" coil spring spacers front and back (from Lucky8). I do get a little (very little!) rubbing at full lock turning. OEM springs currently, I do have HD springs sitting in the garage that will be installed shortly.

Spare tire: I did flip the OEM spare tire carrier - have about 1/2" between the bumper and spare tire.

 

Seems like a big load for OEM springs.
