I bought some BFG AT ko's E load about 3000 miles ago for my 2011 F150 with an FWC Hawk shell.

After a few light snow falls and quite a bit of cold rain - I was thinking I was being overly critical of the tires, or they were maybe overinflated. Now that I have the camper off and the tires aired down to 40 psi, I have had no improvement in snow and wet traction.

After digging a little it turns out my size tires are not rated for "severe snow" (275/65-18's)...?? They are one of the few sizes that it is noted don't carry that designation. Ugh. Could it really make that much difference? Don't really want to buy new tires again (could probably move these on craigslist easy enough) but the performance of these tires is actually somewhat scary with any moisture on the ground - and we haven't even seen frozen snow/ice yet.

Overall these tires are raved about - and for me when it is dry they are great (a little noisy), but in the limited off road driving I have done they really grab. Snow,rain = scary.

Anyone else have this experience or can chime in regarding the "winter snowflake" rating most tires apparently carry (except mine :-()

Thanks!

Have you had them siped?

[pods8]

I had 275/65-20s on my other truck and didn't have any issues in the rain/snow. I did not snipe them.

I'm trying out Nitto Terra Grapplers on the new truck, we'll see on those.

Have you had them siped?

I have not, just spoke to a tire dealer who said I could give it a shot - he said I would have about a 60% chance of being completely satisfied. For $120 it seems a whole lot cheaper than new tires. However I don't like the idea of riding around slipping and sliding.

DD, have you had good luck siping tires in the past, or does anyone have experience with that?

It gets pretty icy where I live so I always sipe my tires. Seems to make a pretty big difference. IMO my BFG's have performed fine in snow and ice. However, performance in these kinds of conditions is probably subjective given that no tire is going to be perfect when its slick out.

Great suggestion, except that I didn't think of it first.

I just met with a client that bought a set of BFG A/T's. He as been very unhappy with them. He saw my Nittos. I told him I opted out of the BFG's for the Terra Grapplers after many years of loyalty to the A/T's. I told him they're less expensive, quieter, smoother and I get better fuel economy. Now he's pissed. OOPS!

The chart below didn't copy well but does list users surveys, highest rated tires on top, the BF AT KO's are 10 of 19 on this Tire Rack survey. http://www.tirerack....y.jsp?type=ORAT

I'm about to replace my Firestone Destinations with another set. I wish they'd last longer especially with the price of tires these days but loaded with the Grandby, the 7.3, and at times dragging 2000# of trailer I would complain too much.

From the following description off of the tirerack site, it appears to say these tires are already siped?

"The All-Terrain T/A KO features an aggressive, computer-optimized, high-void, all-terrain pattern with interlocking tread blocks and innovative siping to provide traction and handling without generating excessive noise. "ShoulderLock" upper sidewall traction bars maximize aired-down performance by provide the clawing action necessary to develop traction and steering control in deep dirt and sand. The tire's internal structure includes twin steel belts on top of BFGoodrich's TriGard (3-ply polyester cord sidewall plies) construction for strength and durability. Single strand beads (a single strand of bead wire is continuously wrapped multiple times until the desired strength is provided) enhance the tire's fit to the wheel to improve uniformity and ride quality, while rim protectors molded into the lower sidewall help shelter wheels from off-road hazards, especially during aired-down operation."

Should have got Toyo Open Country A/T's. I drove them down a forest road the other day that I could not stand on in my hiking boots. 100% ice. I was terrified coming down but survived. And went and bought chains. They have good siping.
