285/75/r16 or 285/70/r17 equates to just under 33 inches and is about 11.5 inches wide, I've seen a few superduty trucks run those with no lift. I personally haven't seen 33X12.5s on a stock height truck maybe someone else has.

I have an 'o3 4x4 and was looking for a larger tire load range E and the only thing I could locate was a Michelin 285 75R16, but they were said to be a softer compound and would not give the mileage of a more standard tire. I could find quite a few larger models in a load range D but did not want to go down thinking I would loose too much in a safety margin as far as load carrying capacity is concerned. Rolling resistance is greater due to lower max tire pressures hence lower mpg. I went from BF Goodrich AT which came standard on my truck to the Yokohoma Geolander H/Ts model . I only have a couple of hundred miles on them and can only say they are much quieter.

Just FYI, I went by the tire shop yesterday. they had 2 325/65/18's that I put on to test fit. They fit fine other than a little bit of shaving on the bottom of the plastic in the wheel well. The owner of the shop has the same truck as I have with these same tires on a stock truck with 22" rims. He did a little shaving, the exact same as I did today, so if he can fit them with a stock truck, no problem with mine with the leveling kit. I have an 06 F-250, Lariat, Crew Cab, FX4, 6.0, with 18" aftermarket wheels.

I just replaced my 43,000 mile set of BF Goodrich Rugged Trail tires with a set of 285/75 R 16-E Nitto Tarra Grapplers on my 04's stock wheels. I have no clearance issues, but I do have a 1 1/2 inch leveling kit in my truck. These tires are 8 to 10 points softer on my Durometer than the stock 4 1/2 year old spare BF Goodrich Rugged Trail. I don't know about a street tire, but 8 to 10 points softer on a race car tire mean's better traction and more wear. Only time will tell, but I wanted a bigger tire and to maintain the load range the original tires had. The original BF Goodrich tires had a maximum load of 3415 lbs. @ 80 psi. The new 285 Nittos have a maximum load of 3750 lbs. at 80 psi. These tires balanced up real nice. The biggest wheel weight that I needed to use was 1 3/4 ounces. I purchased my from Discount Tires Direct who advertise on this site.

I was able to fit 35x12.50's stock 20 inch wheel with just a 2.5 inch leveling kit from donahoe on my F-250. I went with Pro Comp extreme a/t's no rubbing at all.

Had I known about this brand I would have looked at their Dura Grappler model. Maybe nexttime.
