BF Googdrich All Terrain T/A KO's for 2013 F150 Question
 

I've been trying to replace the Pirelli tires that came stock on my 2013 King Ranch with BF Goodrich All Terrain's, and I am being told that the BF Goodrich All Terrain 275 / 55 R20's are discontinued. My dealership seems to have tried pretty hard to locate some, and they have been unsuccessful. I couldn't find any in stick online either.

Would the 305 / 55 R20's fit, or should I just give up altogether?

Thanks in advance.

305/55's may fit, but you might have rubbing issues without a level. 285/55/20 are better for your truck without a level.

The 305/55 will rub even with a leveling kit at full lock. Personally id go with a 275/60, that what im running and love the little extra side way. They are the same width as stock but are 1" taller. Im 2WD with 2.5" leveling kit and 1.25 block in the rear.

I agree with Hardcore...try the 285x55x20 BFG TA/KO's..just a bit wider and a little taller then stock. They are Load range D tires and will ride a little smoother. They will fit at stock height if your truck is a 4x4. The 305x55x20's will fit at stock height on a 4x4 but on the stock 20" wheel's they are real close to the upper control arm...Nitto makes this size in an XL rating which is lighter then the LT Nitto Terragrappler's I had in the same size. These are wide and heavy tires so be prepared for a hit in the fuel mileage and performance too...I lived in Belle Chasse for year's and bought offroad truck tires from Tire Shack...they sold Toyo and BFG's.

It looks like I may have found the 275 / 65 R20's on Tirerack. Is there any adjustment I can have Ford make with the computer so the speed mph thing corrects?

Yes Ford will recalibrate it to your tires. Might cost a few bucks though. Geaux Tigers!

Ford told me and 2 friends that they could only reprogram the speedo for tire sizes that are available on the F-150, not anything else.

I just put 285/55r20 BFG All Terrains on my truck. Seems to be pretty close to the stock size.

I've heard/seen this several times when I was looking for the TA/KOs in 33" size. Decided I'd stay at stock size instead with no leveling kit and I couldn't find the275/55r20 either. My old truck has these tires and aside from the wet traction which suffers a bit I'd love to get some on the Ford. I'm actually thinking about the Cooper Zeon LTZ. They're about half the price of the BFGs, available in factory size, and I've read nothing but good things about them. I'm just not too sure about Cooper in general. If you do find some of the BFGs, I'd like to know where and at what price. Hopefully they'll become available again before I absolutely need new tires. Like a lot of other people, I'm not a big fan of these Pirelli Scorpions.

I'm running the Nitto Terra Grapplers 275/60R20 and had my tuner adjust my speedo.
