Will 285 70 R17 BFG T/A KO's work on my Stock 2003 FX4 17 tire. If so will they look good? I've heard these were really good tire and want to beef up the look of my truck a bit. Thanks guys in advance.

The BFG's are an excellent tire. You will not be disappointed. They will look and work great.

 

those will fit, no problems

 

I love the BFG's! They have a slightly aggressive look but don't have a lot of road noise. I have the 265's on the 17" rim but I don't see why the 285's wouldn't work. And they look great on an F150!!

 

I just put BFG AT 285/70/17s on my '02 150 FX4 and couldn't be happier. They look tough and perform very well. Definitely worth the extra cash.

 

I got 'em. Pics at WWW below. Love the look, hate the performance penalty, but I'm an agreesive driver. Some may not notice.

 

I have them too and highly recommend them. Ride good and you'll be able to store a spare under the back of the truck. I am currently running 35psi on both front and back.

 

I just put them on a 2004 4x2 and they fit fine. They look great and drive okay. I can hardly notice the difference, but I drive like an old lady anyway.

I've had them on other vehicles and they last well, are pretty tough and do okay off road on most terrain, apart from mud.

 

APT,
I have read some of your post and wanted to relay some of my experinces. You may already be aware of the below information but just wanted to make sure. I saw some of the same performace losses when going to the BFG LT285/70/17. When I first purchased these tires I originally ran 40psi all the way around. The ride was on the firm side for sure. I have now set my Rancho shocks at 2 in the front and 3 in the rear and 35psi tire pressure. I now feel the ride is better off road than original tires and better in MOST cases on the road.

As for power, I just installed the 9100 Superchips custom programmer. Even in the 87 tune mode power was much improved and tranny shifts are awesome. The truck is now so much easier to drive and not hunting for the correct gear. It's even hard to keep my foot out of the gas. I'm not talking tire smoking performance but good honest to goodness increases. Believe it or not in either 87 or 92 modes the truck performs and drives better with these big tires than it did with the light factory offering. I can't believe it? I'm currently running the 92 tow mode program. It's Definitly worth the money.

As for brakes i just installed Power Slots with Hawks HD pads and stopping the vehicle is now as it was with the original tire size.

So as you can see i'm now way more happy than i was originally but these mods made the difference.


Hope this helps!

 

Based on what I've read on this board, I bought a set yesterday and love how they look!

They look and fit perfectly on my stock truck. Although I've only got about 10 miles on them, I didn't notice much difference in perfromance taking off from traffic lights. My 3.73 ratio helps. I'll find out more next week on the work commute.

All I need to do now is figure out how far off they make my speedo. - Until I can afford my 9100. I'm thinking they may even improve my mileage slightly.

 

Sawtooth, although things can be done to improve the effects of larger/heavier tires/wheels, having lighter ones would make the improvements you just got even better. Or, save yourself the $700 in other aftermarket parts to not have to "make up" the performance penalty.

alcatl, are you sure you have 3.73 rear end? I didn't think you could get a 3.73 gear in 2002, especially on a Supercab. Do you have the 7700 package? What is your axle code?

 

Yea, I'm sure about the 3.73 ratio. It's got the tow package on it, not sure about the 7700 axle without looking at the sticker. (If I can find it...)

If I didn't know the larger tires were on it, I don't think I would have been able to notice a performance difference on the ride to work this morning. A little more road noise from the tires was noticed though. Ride with 35 psi all around didn't seem any different from the stock tires either.

I've recorded every tank of gas etc since it came off the lot, so soon I'll be able to see how mileage is affected.

Anyone done the calc's between the stock tires and the BFG's? If you take the OD listed on BFG's website and do the math, I get a different Rev/Mile than they list. - Unless I'm doing something wrong.... And why do they qualify the Rev/Mile at 45 MPH? There is a 3.8% difference in the listed OD's of stock vs new tires. I'm no mathematician, but wouldn't that theoretically translate into a 3.8% difference in what my speedo and odometer show?

 

Check your axle code on the driver door sticker. I still don't think you could get a 3.73 gear in a Supercab since 1999 or 2000.

This is my experience. My 99 Supercab had the exact same drivetrain my 2003 Screw has. Weight difference is 300 pounds more for the Screw, max. I put 69k miles on my 99 with 265/70R17 tires. I replaced the tires on my Screw before I filled the gas tank the first time, so I have no exact before experience/data.

This Screw is slower and gets worse fuel economy than my 99 F-150 ever did with 500 pounds of cargo in the bed. I am interested in what will happen when I repalce these tires and go back to stock size. Maybe my sample one sample truck really sucks.

 

Axle is 'H9' whatever that is......

 

Well that means you have a 3.55 LS rear axle

APT is right , you don't have a 3.73
