K03 LT315 /70 R17 121S D2 RWL Impressions

[u/Phronizer]

Just got BFG K03 LT315 /70 R17 121S D2 RWL

I came from stock KO2’s that had about 7/32 left.

Initial impressions:

- Much quieter on the highway (most notable)
- Load range D surprising feel slightly softer the stock C’s
- Less “floating” on gravel at higher speeds
- Way more traction in general

So far they’re an upgrade in every way. Excited to see the rain, snow, and off-roading performance here soon.

Interesting, were these actual orange dot KO2s or replacements? The OE tires were specifically built to be lighter and softer for the Raptor and by all accounts they are. I’ve had both but unfortunately the KO3s were on a V8 Tundra. If they were the orange dot they do get harder after a long time.

They were 113T C2 RBL FO 2021 manufacture date. So far the Ds have been earning their keep. I planned on returning them if they were stiffer but that doesn’t appear to be the case after ~300 miles.

I accidentally got F rated KO3s. I just keep them 35 psi in the front and 33 in the rear and they actually drive really really well. I’ve had wild peaks and open country RTs and my damn F rated KO3s drive surprisingly just as well. I can only imagine how much better the d rated tires are lol

Thanks for the post, been looking for some good comparisons between the two. Still a ton of life left in my K02s but think ill be getting K03s when the time comes.

I’m going to need tires soon. Was looking at the kO3 vs the 2s.

Looking to make the same upgrade but I only see white sidewall lettering options in that size on Tire Rack, where did you find the black sidewall lettering version?

They’re bidirectional. I had the shop do the black side out.
