Bfg at/ko 275/70 r17

[ftbjoe87]

So my current BFG's are very near the end of their life. I am looking to replace them in the next month or so. I have been looking at my options and it seems that they make a 275/70 r17 BFG AT/KO. Has anyone here used these and if so what has been your experience. I will be losing a half inch in diameter but I think this may actually help me with my slight rubbing issue (only rubs when I hit a bump on tight turns.) I have tried the search feature and cant seem to find anything.

This brings me to my next question. On the tirerack they say that this size is not snow rated while other sizes in the same tire are. My current 285/70 R17's are snow rated and I like how they perform. Does anyone know why this size would be any different? It also looks like they have two different versions of the 285's with one getting the rating and the other not. This is probably a stupid questions but I cant seem to figure it out why one would work better than the other.

Not sure, but maybe BFG put extra siping (grooves) in certain sizes? That would help pack the snow a bit, which is what you want--that's why mud tires don't do well in snow. While I've always been a fan of T/A's, and thought the All Terrains were supposed to be great in snow, some here have said otherwise. Personally, I've always had their Mud T/A's--they're awesome in or on just about any surface, but you can do better for snow (than the mudders, that is).

I was going to say the not rated for severe snow tires were E rated tires which would make the tougher and not nice and soft for cold weather....?

While most seem to be E rated, a couple of them are D rated and also not rated for severe snow according to tirerack. So there goes that theory.

Now this leads to another thought. the snow rating, basically indicates that the tire stops within a particular distance as compared to a reference tires' stopping distance in winter conditions. So if it stops sooner than the reference it gets the rating, if it stops after the reference tire it doesn't get the rating.

So, now this leaves another question, does every size tire need to be subjected to the test, or if a 265/65/17 is tested and stops before the reference tire and it gets the rating then so would another tire size like a 265/70/17 of the same tire.

So then, the not rated for severe snow could mean the specific tire/size was not tested so it is not rated for severe snow, could just mean it was not tested therefore not rated, or that it was tested and didn't meet the criteria of stopping before the reference tire and therefore not rated for use in severe snow.

It's nice when an international standard is actually standardised and everyone everyone knows exactly what everyone else is talking about and information about the standard abounds......:bash:

Did you ever get more information on this? I'm looking at the same sized tires and would like to know.
