Your 35s don't stick out too far without the flares on the front? I was worried about trying to pull off 12.50 wide tires with stock fenders
Ugh. My bronco is a terrible role model. and I'm a terrible resource to ask. And "stick out too far" is pretty subjective. However...
The early Bronco is kinda funny because the front axle is 1.25 inches wider than the rear. The original rear 9 inch was 58.25 WMS.
The Bronco Front Dana 44 with Ford Disc Brakes is 59.5 inchs WMS. Mine is a HP44 with Early Bronco shafts, Long side cut 6, and the short side was cut 5/8. I didn't like the way the rear axle looked skinny...so when I built my rear High Pinion 60, I set the rear WMS to 60.
So...the stock front fenders cover the outer TREAD block of the KM2's. The sidewall bulge is definitely farther out, but I think the legal requirement for "stick out too far" is to cover the tread. So that means that if I throw a rock vertically, straight up from the outer tread block, there is a high likelihood that it will hit metal. I went to great pains to center the track under the fenders when I built the trac bar riser...but of course the bronco settled about an inch after I put all of the accessories on it. So now the axle is shifted to the passenger side by 1/2 inch. Coincidentally, my D44 Yoke put a dimple in my exhaust pipe about 1/2 inch deep.
I'm running Hutchinson Rock Monsters at 17x8.5 with 4-5/8 backspace.
I saw about 50 Broncos at Prairie City last weekend. I saw a lot of full width axles. I saw a LOT of tires sticking out past the fenders. I didn't see any tires that stuck out "too far." I thought they all stuck out "just right."
