they ride well, michelin aquired them before they developed the ko2 and they actually ride as well as my old michelin lt 2 radials on the street. the rubber on these is more compliant and therefore gives more grip and a better ride on the road. the trick is figuring out what pressure you need to run them at on the street. a load range e tire for instance can hold about 3400 pounds at highway speeds, at this load bfg recommends something like 50 psi. my trucm doesnt weigh 13000 pounds it probably weighs about 4500-4700. so i run them at 30 psi, or less. its pretty common for people to run too high of air pressure on our trucks and thats why everyone says the e rated tires ride hard.

i got mine on my stock 2000 sr5 in april and the next day put 1000+ highway miles on driving to utah. they were great on road and off. other than they have rubbed a bit when making tight turns... no complaints at all.

I've had them on for a few weeks. They are quiet on the road but definitely made me realize how bad my 18yr old suspension is! Bumps are tough with old shocks and new tire and I have rubbed on turn hitting small bump. I'm running 265/75/16. Otherwise I like them. They at first were probably more aggressive looking than I thought after I put them on, almost like a mud tire but I like them more and more each day. I'll be doing the tundra trd, 5100s and OME 906 setup soon to refresh suspension and get a little lift so that will probably solve the rough ride and rub. I bought mine at 4wheel parts at $627 + tax (got $70 automatic rebate at truck and jeep fest).

All of this.
BFGoodrich has belonged to Michelin since 1988, when GoodrichCorp ditched tires and sold usage of the name and whatnot to Michelin. Any BFG tire since then (As well as Uniroyals) has been designed and engineered by Michelin.
The only C and D rated Ko2's are 15" and 17", for now. Which means you're stuck with the E rated for 16"s, which you should run at a lower psi than normal for a comfortable ride. Our trucks door sticker recommends 32 psi for a PMetric tire, fairly low already.
The issue with running an E rated LT tire is that they are NOT designed to be run at low pressures. They are meant to be run at pressures recommended by manufacturers who recommend an LT tire in E rating. At low pressures, they will heat up faster, and they will be more prone to cracking, due to the thickness of the rubber and general composition.

its a bit more complicated than low psi = damage to the tire. what causes damage to the tire is actually the tire deformation. imagine you had a big truck and ran it at the the regualr tire pressure, and it was loaded down and the tire deformed, this would be the same as the unloaded truck with too low of pressure. anyways imagine you had a big truck loaded up and increased the pressure to carry the extra load, now the tire is properly inflated for the load. now you take that load out of the truck but the tires are now over inflated, the ride is harsh because the tire does not deform at all. there is a perfect balance between the ammount of tire deformation and tire life.
basically the pressure should be adjusted to have the correct amount of deformation. too much pressure and the center of the tread will stick out and give a harsh ride, too little pressure and the tire deforms to much, giving poor onroad handling and fuel economy. the correct pressure will give a good ride, and good tire wear.
Im going to contact bfg and have them explain exactly what pressure I should be running on road to get the best overall performance out of my tires.

That is precisely what E rated tires are designed to do. Handle high loads and no loads without changing the pressure. Could you imagine if 18 wheelers running 19.5's and 22.5's had to lower all 18 tires air pressure every time they unloaded? That'd be absurd!
The original E-rated design included 10 sidewall plys to resist deformation under load. Nowadays, E-rated tires often only have 3-4 fabric plies and 1 steel ply, yet they are still rated as 10-ply tires (because they can handle the same load after DOT testing.) Using minimalistic ply counts is exactly what BFG did with the Ko2 to increase comfort yet, allow for greater loads.
When you call BFG/Michelin, and ask them, I bet they'll ask what load rating is recommended for the truck. That's what I would ask, at least, having worked for Michelin B2B for some time.
Also, in order to get the same amount of 'deformation' on an E-rated tire compared to a C or even D rated tire, you actually have to release MORE psi, due to the structural strength of a 10-ply rated tire versus a 6 or 8.

I put them on the wife's Tacoma 2015. Did small level kit and the TRD Wheels with BFG KO2's. I am a long time fan of BFG's AT. had done many other tires and always went back to missing it for every reason. The new tire design I couldn't think twice about getting for hers and I'm not regretting one bit. Sharp looking tire. Proven reliability. And no big noise in can driving down highway. 265/75-16 (31") is perfect.
I have same size on my 97 a Runner in duratracs. deff slightly more aggressive but I love them no question about it. I would do BFG next time just for solid white letters and tread I love. I did duratracs because they are amazing year round and because I could get C load range instead of E.
Go for the BF's you will not be disappointed.

I have the General Grabber AT2 and am very happy with them.

I’m running BFG ko2 load E and haven’t really heard any road noise they’re pretty quite for an A/T tire. Also I’m running 265/75’s as well no issues I ran it with stock suspension for a few months no rubbing or issues. And my suspension was non existent saggy as hell. Can definitely feel the weight of the tires though.:thumb:

Ive had both the T/A and the K02 on my work truck ( ram 1500 ) the T/A lasted s long time but I didnt like the ride. Truck felt very washy on the roads. The K02’s seem ok. My mechanic buddy said they will wear fast because of the weight of the truck so time will tell. They dont seem noisy but they do feel like a soft tire. When the tires are hot you can even hear them sticking to the pavement when driving slow.
