BFG Mud no m&s?!

Hi all,

KM2s just noticed that the new ones I have had fitted are not marked with m&s as my old ones were?!

Not overly fussed but I know the local gendarm likes to inspect tyres if they have a check point where we go at Christmas.

Any clues......?

I looked at the BFG website to see if I could answer your question, but with no joy.

However, I looked at the label for BFG KM2 255x85R16 and they seem to carry an A rating for both fuel efficiency and wet handling and quiet Dba.... that can't be right, can it??

Ko2 is the all terrain right?

Maybe I am wrong but I am convinced my old tyres had m&s marked on them.........

Took some late night googling but here is the proof - found quite a few photos where they are clearly marked however agreed not with snowflake. Might have to zoom a little. There are better pictures agreed but it's just above the a of terrain.

Having the letters M&S is not the same as having the Mountain/Snowflake symbols. Only the latter means winter rated.

Fully appreciate that but then what's the point of having it marked or not marked as the case may be!? At least I've proved my memory is not quite gone!

The severe service winter tire designation looks like a peaked mountain with a snowflake in the middle. When you see a tire with the mountain snowflake pictograph on the sidewall, you know it meets specific snow traction performance requirements set by the Rubber Association of Canada.

A sidewall mark of M+S (or M/S, M&S, MS) means that you have an all-season tire that has been approved for use in mud and snow by the Rubber Manufacturer's Association (RMA). These tires will provide traction in light snow, but we wouldn't want to be caught in a blizzard with a set of M+S tires. pickup 90 TD5 2006

They just mean different things. M&S stands for Mud and Snow and indicates an open tread that will work well with those sorts of loose surface. The Mountain/Snowflake symbol indicates that the tyre is good for much lower temperatures, typically below 6C, where the M&S tyre becomes less effective.

There's more detail here: https://info.kaltire.com/what-is-the-winter-tire-symbol/

Edit:
Sorry, I've just re-read your original post and realised what you mean. I don't know why the the KM2's aren't marked 'M&S'. Perhaps they consider it unnecessary given the obvious tread pattern.

Great thanks all - only really asked because the gendarme passed me clear due to the m&s rating last year on a road to a ski station where you are required to have either chains or snow tyres. My 2p worth is that the mud terrains performed superbly in varied snow conditions last year from foot deep to compacted - maybe because I stayed with the thinner profile?

I guess BFG have removed the lettering to encourage folk down the more specific winter tyre route.

When you look at the eBay shop adverts 9/10 say Summer Tyre in their descriptions of the KM2

I guess you could say the key is in the tyre name and type.

Snow or not I'd not swap my KM2's, they are far more use to me than an ATR in general conditions.

I not longer drive in snow and ice anyway, as it's so much of a risk it's just not worth it.

It doesn't matter what you are running it's a high risk especially of damage. Watts Volts = Amps.
Amps X Volts = Watts
