I ran 245/75R16 10 ply KM's with a 2" BB for ~3 years. They were the perfect size for that amount of lift. If you go any bigger, you will probably have to run wheel spacers if you disconnect when offroad and don't want to hear any rubbing.
"mall crawlin's for city slickers! Round these parts we go porch crawlin."
Haha that's exactly right! When you don't have an RTI Ramp, use the front porch/brick flower bed!

Thanks! I hope to do some wheeling soon. I know I'm going to need to look into sliders here in the very near future... that and a few skids. Also, I'm going to need to relocate the lights. I imagine they will snap off quick. I may look into a roof basket and mount them on that. I need to be careful though as I only have about 10.5" of clearance left to get into the garage!
Originally, I did not have any rubbing with the OME HD lift and 245/75R16 Duratracs. Once I installed the wheel spacers, I had rubbing in the front at full lock in reverse. I trimmed the front bumper and wheel well lining to fix the issue. I used a razor blade on the bumper to remove about an inch of material. I used metal sheers on the wheel well lining. I think it turned out pretty good.
I realized I didn't have a decent picture up of the finished product so I snapped one this morning. It isn't the greatest quality but it does show pretty well the difference between sagging stock springs and the new setup.
I did a little math because people always talk about losing gas mileage when they go up in tire size. While this is true because of 1. a higher vehicle means more wind resistance and 2. heavier tires take more 'umph' to roll, you also have to take into account your distance traveled is not accurate anymore unless you have re-calibrated the tach/speedometer. So here are some numbers:
225/75R16 is 29.29" tall.
245/75R16 Duratrac is 30.7" (as advertised on their website)
29.29 / 30.7 = 0.9540717 * 100 = 95.40717
100 - 95.40717 = 4.59283% Larger Tire than original.
If you travel 200 miles as indicated by your mileage counter, you have actually gone 209.19 miles.
200 X 0.0459283 = 9.18566 + 200 = 209.19
So for the important numbers for this condition (30.7" tire replacing a 29.29" tire, no other variables changed):
Every time the mileage counter travels 217.73 miles, add 10 miles to it.
For every 1000 miles as indicated by the mileage counter, you have actually traveled 1045.93 miles.
Considering this in the world of gas mileage importance:
Let's say a normal tank of gas last 275 miles as indicated and it takes 17.5 gallons to fill the tank back up:
275 / 17.5 = 15.714 MPG
With the larger size tire, we need to add 12.6 miles to it:
287 / 17.5 = 16.43 MPG
As you can see, a normal tank of gas has lost 3/4 of a gallon per mile only because the distance traveled is no longer correct.
Sorry if that was boring. I wanted to write it down somewhere for future reference and figured someone else may want to read that.
