Anyone running 265/70/16 BFG AT on all stock?

Need new shoes? This is the place to discuss.

Hello all. I know this may seem like a typical "will it fit" post, but hang with me here. So, I know from "researching" this topic that 265/70/16s should fit on a completely stock TB depending on tire. I currently run 245/75/16 Goodyear MTRs and I am looking to downgrade to something a bit less agressive and less noisy in the BFG All Terrain. It certainly appears that many 265/70/16s fit on stock TBs, but I have not found anyone running this particular size in this particular tire. Any advice would be greatly appreciated. Thanks in advance!

from the online tire size calculator

Almost the same size. Measure the current clearance from the tire to the ball joint/UCA and if you have enough to cover the width difference it should fit. You may need a set of spacers and some minor trimming. I am not promising you it will fit though.

BTW that took me all of 2 minutes to find and post for you. :slap:

Thanks, but BTW that is not what I was asking. I have seen that same information you posted time and again. I was asking specifically if the BFG AT will fit due to the tread pattern not if the tire size in general will fit.

What he's saying is, you're close enough to the ball joint that no one can give you a surefire answer. Go look at it and measure the space between the tire and ball joint. If you've got .5" or more, you're probably clear, maybe only needing a little ball joint grinding to be safe. If you don't even have that much room, probably won't fit without a spacer.

You'll be picking up a 3/8 to 1/2" on both the inside and outside of the tire in width if the numbers above are correct. Check the measurement from the tire now and that should answer your question. If not you'll have to just keep looking for the answer or bite the bullet and figure it out by trying.

Oh and thanks to CBRguy for giving you his input so quickly.

One note about this... don't use the nominal size. It's pretty easy to find the measurements on that specific tire on TireRack or the manufacturer's website. Also wouldn't hurt to check the manufacturer's specs of your current tire to compare. Also keep in mind, if your tires are worn, they'll be slightly smaller than advertised. Probably not worth worrying about, but you could even compare your worn tread depth if you really want to get technical. :happy whip:

I went through the same thing when I got my tires, problem is everyones truck is slightly different. I decided to err on the side of extra space rather than buy it all and it didn't work. After having mine, I am convinced I could run these tires stock with trimming and wheel spacers. But I wouldn't recommend it to someone over the internet.

Food for thought.

I have test fit 265/75/16 BFG all terrain tires without spacers. They just barely hit the ball joints. I would imagine that they will fit with a little grinding at the very most.

that is one advantage of buying from a local tire shop.
You can give them a call and tell them what the deal is. Most of the time they won't have any problems test fitting the tire for you especially if it isn't one of the big chains.

Thanks everyone for the helpful advice! I do think the best bet is to go to a local place and see if it will fit. Hopefully they won't mind too much as either way they will be making a sale. Also, has anyone tried/know of someone who has tried the BFG Rugged Terrain T/A? Apparently it is a brand new tire that seems to be a mix of the Rugged Trail and the All Terrain. I put a link below to BFG's website. Again, thank you!

Quite a few new Ford's come out with the Rugged Trail. If your mainly on road, intend to drive on mostly dirt roads that are dry when your offroad I would think they would be a good compromise over the AT as far as better fuel mileage and basic offroad ability.

The Rugged Terrain will give you even better use for wet dirt road type of roads. But if you expect to drive this type of road or worse more frequently, I'd go with the AT as a minimum.

I went with the Yokohama Geolander AT/S tires back in 2007, I love them! Great water dispersion on pavement and traction off road, they are also lower cost than the BFG AT's, I will be stepping up in size from my stock 245/70-16's to the 265/75-16's when these wear out, on target to get the 45k miles they are warranted for.

I took the above info and ran with it...

I have 2" suspension lift front and back and no wheel spacers.

2" lift with stock 245/70/16 Yokohama Geolander AT/S's.

A "little grinding" was necessary on the upper ball joints, I used a flapdisc instead of a traditional grinding wheel to keep the heat down so it did not cook the bearing.

New 265/75/16 Yokohama Geolander AT/S tires on!

No other modifications were needed!
First time off road with new larger tires.

I did buy an additional stock rim and mounted another new 265/75/16 tire to use as my spare and plan to rotate this onto the vehicle as I do normal tire rotations.

This larger spare tire did require me to cut the tire stop on the drivers side off flat.

The spare does barely clear the trailer wire harness

and barely touches this bar.

Very cool, glad I could help. One thing, I wouldn't leave that spare underneath with it touching the panhard bar. That is a moving part and you could damage either it or your tire.

It is not actually touching, there is a small gap between the tire and panhard bar, I will keep a close eye for any rubbing on either of them.
