BFG AT KO2

[Big Whiskey]

Lots of pix with clean, new, oiled up, knarly, off-road tires on waxed trucks. None with dirt on them in conditions they were made for?

Those coopers you're running are more aggressive than the BFG's....but your truck always looks pretty clean to me!

is this what you are looking for? they are not KO2's but they are BFG's.

Was able to get the pressure load data from BFG for KO2 in LT275/55/20

 

KO2 GOODYEAR LS2

PSI LOAD 35 2403 *.91=2187*2=4374

35 1750

40 1920

45 2085

50 2275

55 2400

60 2550

65 2680

 

Here's the data with some extrapolation based on load/air pressure and averaged rate of change between 5psi increments. What this means is if you have a GAWR of 3900F and 4300R you only need 41F/47R to preserve your load rating without having to assume anything or having too harsh a ride. The smoothing isn't perfect i'm working more info to provide a more linear progression.

 

 

35 1750 36 1786 37 1820 38 1854 39 1888 40 1920 41 1952 42 1982 43 2012 44 2042 45 2085 46 2124 47 2162 48 2200 49 2238 50 2275 51 2302 52 2327 53 2352 54 2377 55 2400 56 2431 57 2461 58 2491 59 2521 60 2550 61 2577 62 2604 63 2630 64 2655 65 2680

Curious where to find the 3900F/4300R ratings?

 

(highest I can find is 3950F + 3950R axle ratings, and 7600 max GVWR )

You're correct it's 3950f 4300r not non-nht are 3950r

Finally some pics of my ko2's

Has anyone tried a KO2 in 285/65R20 with a 2.5" level? Lots of guys are running the 275/65/20 in various brands and the 285's are only .4" taller and .5" wider. I'm surprised nobody has posted experience with this size yet.

Subscribed...Interested in getting these at some point

so far everyone in this thread has put 275/60/20 KO2 on their trucks. which is roughly 33x11, has anyone put the 275/65/20, it is basically 1" taller at 34x11. just curious because It may be the perfect size with the 285/65 maybe too large.

 

post pics let me know.

Here's the pics of my truck (2015 All Terrain) I have the 285/65/20 with a 2.5" level in the front only. There is only a slight rub in the front when i lock the tires while turning. I have taken it on gravel, mud, and packed dirt and haven't had any issues with the tires being too large. I love them, been over three months so far, they have been awesome.

 

Here is where the tire rubs on the inside of the well. Not sure if it is because the All Terrain's come with that carpet crap. It would be easy enough to cut out, and the piece it is rubbing on actually is sagging forward a little bit and at an angle heading towards the tire. Not sure if you can see it that well in the picture.

Here is the front and rear tires, sorry if they are at a crappy angle.

 

Forgot to mention, these are on the stock 20x9 all terrain wheels that come on the SLT Plus package or whatever.

how big are your tires on your truck what are your tire measurements. From ground to top of tire looks awesome btw
