Oldtime I will post pictures of my rims a little later. Let me know if you think the silicone will work. Thanks
The tires were listed at 4WD Hardware for $25 off each tire when you buy four. I they listed there for $176 each prior to discount and no sales tax and free shipping. Win, win. Here is the link for 4WD tire page. https://www.4wd.com/p/bf-goodrich-7-5r16-tire-mud-terrain-t-a-km3-21105/_/R-BDKZ-21105 Here are my two worse rims. One KH one ? Let me know if you think silicone would work or tubes? Thanks again. Edited by masscj2a - 21 July 2019 at 11:48am |

I suppose that you could weld plugs into the rusted out holes and drill new holes at another spot.
Tubes will cure the sealing problem, but if there are shape edges around the rusted holes they might cut the stem.

Bill that's what I was thinking as well. For the time being, I'm going to have the Eldorado tires dismounted and the bfg's mounted on those rims. I can work on these later.

Yep, the 7.50-16s like to rub the vertical inside of the rear wheel wells on stock wheels and really limits turning angle. I got some 16x6 steel wheels made with 2.75" BS. Spaced the tire and wheel out ~1" on the inside and ~2" on the outside compared to stockers. The tread does not stick out the side of the body, maintains turning angle, doesn't rub the tub, and sits just at flush with the front locking hubs.

LT235/85R-16 was the stock tire size for Ford 3/4 ton and 1/ton pickups through at least the '80s and '90s. I think Chevy and Dodge might have used them too. That's a lot of 4WD trucks that want load range E mud tires. Trailers only use LT235/85-16 tires because they are available for the trucks and (arguably) hold up better than trailer tires.

OH O.K. Bob ! I just noticed that a lot of trailers are running that size of tire and figured that's why they are virtually all 10 ply rated. The more modern 85% aspect ratio is a tad wider than I like. On my jeeps I rather prefer the old 100% aspect ratio that was used with early numeric tires. Apparently the new BFG 7.50 /16 appears to be somewhere near the old 100% aspect ratio. The reason mfgr's went to a lower aspect ratio was to reduce possible roll or bead separation during fast cornering. A long time ago the 78 aspect ratio was determined to give the greatest ride height while keeping side roll to a minimum. And that's why the 78 and later 75 series aspect ratio have been common for so very long . Masscj2a, I really don't know if silicone will hold or not but I would consider trying it in a pinch so long as the hole was not oversize and the silicone was allowed to cure overnight before using it.

i have two more similar rim's on an old cj5 out back. I'm going to dismount the 100 year old bfg on those and see how badly rusted those are. Then I will get them blasted and if good, I will paint up a set of five. But for now, I am going to mount them on the steel rims on there now. Going to get that done tomorrow morning. Thanks for the input.

OK, got a little side tracked this week. Decided that the brake line kit I have gotten from KW was not the correct one for my 3b, so sent it back. Not their fault I guess as we know how these things go, one owner changes something and everything is off. I have 11 inch drums all the way around, so that was a problem. So decided to go ahead and make all of my brake lines myself. Bought all new flex lines, fitting and clips and had at it. Good news is, all the bleeder screws and fittings came right off. Bad news is I hate doing brake lines, I know as much of you loves doing them, I do not. Decided to do that while the B was up in the air, awaiting the new sneakers to get mounted. Have the tires and could not pass on doing the lines at this point. Then yesterday when I was done bleeding the new lines, I went for my test drive with the new tires. It was great at the beginning, tires are great, ride is better, noise level is down, everything going great right ? Until my oil pressure gauge line let go, spewing motor oil all over the new exhaust and engine. My buddy said it looked like a kamikaze pilot looking for a place to crash. So before pictures and time relaxing, it was back in the barn. Repaired the oil line, cleaned the motor compartment off and time to head in for a few drinks. Enough for one day. But here are the pictures of the new sneaks. Lock to lock has no rubbing and still over an inch to spare. I did do the rock climb, but could not take pictures as the gas was exiting my cap at a rapid pace. Just long enough for me to jump out and see that the right rear was off the ground 5-6, left rear was tucked and just slightly away from the inner fender well. But would probably rub with more deflection. The Jeep steered very well and rode pretty good at 25 PSI. May go down to 20 PSI today and continue to release air until something negative happens. Stay tuned for that and an off road ride report. So far I like them. ( Like all my KM2's) Jeep and tires could benefit from a slight body lift and or 1 or 2 inch soft spring lift.

Definitely the best looking Jeep radials I've ever seen.
And the narrow spare tire overhang looks good too. Ideal maximum diameter on a standard - non lifted flatty. They look to tuck up under the fenders real nice while the narrowish rounded tread profile helps to keep the body/spring rubbing to a minimum. I just gotta have a set of those for my daily driver. Now if we could only get them is 6 PR. Thanks and keep us informed.

Not sure bfg will ever make them in six ply, but if they do, let me know. Just put 60 miles on them and still liking them. Next I will drop them to 20 psi on the street and see how they run. Then I will take em off roading. I have a like for the km2, so I'm sure I won't be disappointed with the performance, but don't want to get to deep into mud yet. I'm still doing things to the under belly and hate caked mud in the face. But after a few more things the gloves are coming off. Trail ride in NH on the 10th, so I figure we will see mud then.

What is the width of the wheels you're mounting the new BFGs to? I'm guessing you have something wider than the old 4.5" wheels?

Not sure what Mark used but I prefer to run my tires on a rim that's a little narrower than the tire manufactures suggest.
A narrow rim causes the tread crown to raise under normal air pressures but I tend to run lower air pressure than the tires are able to handle. So the tire crown naturally flattens as the pressure is reduced. And the slightly narrow rim also increases the sidewall bulge. Extra sidewall bulge helps to protect the rim lip from damage. The 4.50 x 16" KH wheels are intended for use with 6.00 x 16 tires--- but I like to use 6.50 or 7.00 x 16" tires on those rims. The heavy duty 5 x 16" KH wheels are intended for use with 7.00 x 16 tires ---but I like to use 7.50 x 16" tires on those rims. The rarely seen 6" x 16" KH truck wheels are intended for use with 7.50 x 16 tires ---but I like to use 235/85R 16 tires on those rims. |

The rims I used were 6.5 inches wide. I also like using narrower rims normally. We call them the poor man's bead locks. Would have gone 6 inch, but these are what came on the Jeep when I bought it.

Well, took the B out for it's first real wheeling so far with the new tires. Went to an area in NH around Hillsboro. Mild stuff in the beginning but we did get into some granite boulders and ledges. Mostly easy stuff, but some stock flatties probably wouldn't want to do. One spot of mud I watched closely and it was around a foot deep and the tires carried the B right through at just above idle without breaking loose once. I went slow through that just to see where they would spin and they just kept trudging . One the granite, they never seemed to spin and we went through a couple of up hill Boulder fields. I just pull out the throttle a little bit, kept my foot off the pedals and let the tires work. They did amazingly well. I was running on the stiff side with 20 PSI in the tires. Only because we were running pavement a lot in between. I'm dropping my air down to 15 today to see how street handling on paved roads would be. If descent, I'll run that pressure from now on. I was impressed how well overall they performed. Next time I will supply video.

There was no rubbing of the rear wheel wells or the front tires hitting leaf springs or bottom of fenders. That was with zero lift and stock springs. It was sprung well more than once and had zero so far. Just thought I'd let you know that.

That's great to hear that.
I had already figured it should be a very close fit with stock suspension. Myself, I love to push the standard limits with very minimal modifications. I spent a lot of time thinking about about Willys Jeep tires over the weekend. Considering every type of terrain and percentage of use on each type of terrain. Paved road, gravel creaks and roads, dirt and turf, rock (6"+), forest, mud,, Ice, snow, sand, soup mud and more. No these tires certainly are not specialized for any particular use; but... The 7.5 KM3's are at the very top of my list for correct size and a "do all" universal design. |

One of the biggest reasons I like the km tire line is it's an all around performer. I have never been let down off road and enjoy the pavement characteristics. My go to tire line and they don't pay me to say that either. 🤣

I now have a full set of 5 on order. The 4 Wheel price was too good a deal to pass up. Future plan is to mount them onto 5" x 16" heavy duty KH wheels on a daily driver flatfender.
