The 70’s are 32.8” and the 75 is 33.8. So basically a 33 vs a 34. The factory BFG’s are E rated and weigh-in at 56lbs vs the C rated 70 at 57 and the E rated at 61-63lbs each. I personally would go with the E rated for the 10 ply construction and higher load capacity. I am likely going to go with the 285/70/17 E rated unless I can confirm no rubbing on the 75’s.

Has anyone confirmed fit and no rubbing with the BFG 285/75R17 size and stock steelies (+no lift)?

I’ve seen these on a couple trucks but they had 0 offset wheels. Purportedly no rubbing when loaded & off-road.

I can confirm no rubbing on BFG KO3 (E rated) 285/75/r17 without a lift on stock alloy (don’t have the steelies) on basic mountain off road trails. Also, not the most important thing, but they look great.

Thanks @bradb622! Good to know on the trail performance and looks are an important factor, no doubt.

I believe the 17” alloys are the same offset as the steelies at +55mm. Might be the difference of 17x8” (alloy) vs 17x7.5” (steel). So should approximately come out in the wash on “installed” tire section width placement in the wheel/tire space envelope.

Aside from the rubbing factor: How does it drive? Ride, acceleration/braking, transmission behavior, handling?

Ive got those ko3 tires close in size - 285/70R17.

I’d say they are a little more “squishy” compared to oem size ko2. But not a huge difference in ride, just more, I’d say, compliant.

For comparison these are Goodyear Duratracs 255/80r17 on stock steelies, no lift. Great fit, no rubbing.

BFG KO3 285/70/R17 on 17x8 ET 40 wheels. No rubbing and plenty more room to go 295 or maybe larger, but I am happy with this look, performance and it barely fits in the garage with these. No lift.
