BF Goodrich All-Terrain T/A KO's
I'd like to replace my stock Goodyear Wrangler P255/70R16's with something a little bigger.
I'm seriously considering the BF Goodrich All-Terrain T/A KO's sized at LT285/75R16.
But, I have a few questions.
First, do you think these tires would be too obnoxious (big) for my SuperCab 4x4?
Second, are the tires noisy at highway speeds? I want a relatively quiet tire.
Third, do the tires run smooth and true at highway speeds? Do they provide a reasonably comfortable ride?
Fourth, how do the tires perform? Both on road and off road?
And finally, how much did you pay?
I'd like to see some photos of a truck similar to mine with the same tires on stock rims.
Basically, I'm looking for a larger tire that runs great on the highway, and to a lesser degree, off road. The tire needs to be quiet running and handle nicely on wet and dry pavement.
Thanks!

That is an Eagle Series 171 16x8 wheel with the BFG 285/75/16 AT KOs

Crappy side pic. Hopefully the weather will warm up and I can clean and get new ones.

I just put these on my Expedition. Here's the thread, which includes links to photos.
https://www.f150online.com/f150board...ML/000743.html
In short, these are great tires. They ride and handle better than the stock Godyears. I have the same size tire on stock Lariat wheels on my F-350 PDS Superduty, and they're great on that truck, as well. The stock wheels are only 7" wide, and BFG recommends a 7.5" wheel. Mounting on a 7" wheel may cause the center of the tread to wear out a little faster, but lots of people do it.

JohnD...
Those BFG's look awesome on your truck! I've basically got the same truck... same stock rims and such. Thanks for the photo, now I am getting anxious to buy the new tires.
Matt90GT...
The BFG's look great on your truck too... You have the off-road package, no? Then that means that you have 17" rims?

Ok, a couple of more questions.
I ran the new tire size through the tire/gear calculator (http://www.andthensometoo.com/calc/tiregear.php) and here are my findings:
The stock Goodyear P235/70R16's are 9.3" wide and 29" in diameter... which are the measurements that the PCM is calibrated for in calculating speed (MPH).
My "optional" Goodyear P255/70R16's are 10" wide and 30.1" in diameter. My speedometer is currently off by a few MPH because of this. The tire/gear calculator says that my speedo will read 60 MPH when I'm really travelling at 62.3 MPH.
The BFG P285/75R16's are 11.2" wide and 32.8" in diameter! The tire/gear calculator shows that when my speedo reads 60 MPH, I'll actually be travelling at 67.9 MPH!!! Talk about a speeding ticket waiting to happen!
Also, my 3.55 gears are 3.55 with the stock tires, 3.68 with my optional Goodyears, and 4.02 with the BFG's!
So, it looks like I'll definitely have to have my speedo (PCM) recalibrated. And it looks like I'm going to lose quite a bit of low-end torque. Anyone know what's involved in recalibrating the speedo?

Bluecrab,
Fixing your speedo is nothing more than changing a small plastic gear. There is a fitting on the very back of your transmission held in by one 11 mm nut. Take that off, pull the fitting out and there's the gear. Be careful when you take the clip off that holds the gear on. Count the teeth on your gear, notice whether the splines go from right to left or left to right with the "tip" up, and figure out what the percentage of change is from your original tire size to your new tire size (you need that % fewer teeth on your new gear). Go to your nearest dealer, spend $8.00, then reverse the process to put it back together. It just took me longer to type this than it did to change my speedo gear. Just to give you an idea, I went from 255/70-16 to 315/75-16. Went from a stock 20 tooth black gear to a 17 tooth green gear. Sorry this is so long, but I hope it helps.

You calculated your gear ratio incorrectly.
With the bigger tires your effiective ratio is smaller in number. IE with the 32.8" diameter tire your effective gear ratio will be 3.13 instead of your factory feel of a 3.55. This is why when you get bigger tires you get a larger numbered gear ie go to a 4.11 and your truck will feal closer to the factory.
You can only change the speedo plastic gear on the 97 and 98 model year's after that it is adjustable via a computer at your local ford dealer. You may have to lie about the tire size and gear ratio to get it correct.

I love the pictures of your truck. I have a question, however...
As you know, I want to put BFG All Terrain LT285/75R16's on my stock 16x7 rims. One of the reasons I want a bigger tire is to fill the wheel well a bit more on my 4x4... the stock P255/70R16 Goodyear's just look too small for the truck. Another thing I want is a bit more width, or "reveal" as you call it... How did you get the reveal on your truck? Will the larger tire do the trick or do I need to put spacers behind my rims? Or do I simply need wider rims? Thanks!

My wheels are 16 X 10 wheels. They stick out because they are so wide and because of the offset. So if you want a reveal like that, you'll have to go with wider rims.

Blue,
BFG KO's are definitly the way to go. Ive had them on my truck for about a month and they look way better than the stock Wranglers.
There arent noisy at all, not like i can really hear them over my duel exhaust. We just got 2" of ice down here and i was running around in 2wd the whole time and had no problems. They hook up like no other. They are well worth the money and if you rotate them regularly they will last forever!!!
