Those rock rails look great! Have you decided which way you are going with tires/wheels?
Appreciate it. I am very happy with how the rails look, I hope they function as well as they look. I will try them out at Moab in report back
As for tires/wheels, I ordered 33x12.50x15 BFG Mud Terrain KM2's. I am happy with these tires traction, on rock/mud/sand, and the on road performance of these tires has been great, so I am sticking with them, just going down one size. I am going to mount them on my current factory 8" wheels, and hope they don't rub
I thought about going to 33x10.50, but for the soft conditions down here where I spend most of my wheeling time, the slightly better floatation of the 12.50 just makes more sense. If I lived somewhere with lots of rock and lots of on road ice, the 10.50's would be a better choice. The slightly wider foot print of the 12.50 vs the 10.50 should be better for side hilling, too
After temporarily switching down from my current 35's to my buddies borrowed 33's, I can honestly say that I am way happier with the Scrambler's over all performance with 33's

The 4.10 gears push the 35's with no problem. I drove it from south MS to almost TN with the 35's and the T176, and it drove perfectly. It could hold any hill no problem. But, with overdrive, the 4.10's can not push the 35's satisfactorily

The RPM decrease coupled to the 258 is just too much. 4.56 gears with 35's and overdrive might be better, but I am very happy with 1-4 gears performance with 4.10's. For me, 4.56 would be too deep, too much of a negative trade off, just to gain some RPM in overdrive. Even with 4.56, the 258 might not have "enough" to push 35's on interstate grades/head winds.
It might sound like I am complaining about my MPI equipped 258's power out put, but I am not. I am very happy with my in line 6. A V8 could probably cope better with 35's/4.10's/overdrive, but I am happy with my 258's gas mileage and power output. And with current gas prices coupled to the fact that I like to drive my Scrambler on road as well as off road, the anticipated fuel mileage increase I hope to gain by switching down to 33's and adding over drive, should be a welcome plus. My 35" tire/T176 best highway MPG was 16, I am hoping I increase to maybe 18-19 MPG
35" tires + T176 +75 MPH = 3,000 RPM
33" tires + T5+ 75 MPH = 2,400 RPM
Besides the highway gains with the 33's, the around town driving is much better with 33's, too. The Scrambler feels more "spunky", stops easier, steers easier, is easier to get in and out of, and I can actually clean the roof without a step ladder
The only down side I see by switching from 35's to 33's is the slight loss of ground clearance. I will "drag" more now, but I am mitigating against this fact with a thick gas tank skid plate and rock rails. My last vulnerable spot I am worried about is the sheet metal between the back of the rear tires and the back bumper. I need to get something custom built locally to protect this area. The Dana 300's low hang down is also an issue, so in the future I might re drill the T5's rear housing to "clock" it up, and then build a new, flatter skid plate. That is only if it becomes that big of a deal.
After driving with 35's for a year, I feel like my "down grade" to 33's will be for the better. The 35's just seemed like a "bridge too far", if you know what I mean

I also think that a close to stock Jeep CJ's powertrain is much happier with 33's, and after real world driving with 33's for close to 20 years, both on and off road, I will stand by that statement

For the trails that I like to run, 33's are adequate. 35" tires would be nice, but they also bring about a mind set of more capability then what the close to stock vehicle actually has.......
I know it's a long answer, but I just wanted to try and explain some of my thoughts
