Just bought a set of General Grabber ATX's. One thing I like about them is they have the 3 Peak Snowflake rating which will be good for trips to Mammoth and Big Bear. My research tells me that 3PMSF tires are better/more stringently tested than M+S tires for snow performance.
However looking at CalTrans it looks like they only define "Snow Tires" as "M+S" tires:

I am guessing their website is just behind the times, but I also know they can be super anal when it comes to tire/chains, especially on the drive up to Mammoth. It really would suck to drive all the way up to Mammoth and encounter that one CHP officer who doesn't know what 3PMSF is and only allows tires with "M+S" letters.
Anyone have any experience with the CHP and how they handle this, anyone ever get turned around because they have 3PMSF vs M+S tires? I know there are a ton of people who DGAF and drive on regular tires and get away with it but Im more interested in how they handle 3PMSF tires.
