I've been told that what I have is not a "premium brand"!
I only ended up with two because that's what my cheapskate garage owner got me, as he thought I was going over the top and surely we weren't going to have another winter like last year....

Well he found out about four days after he'd fitted them that he was wrong about the last bit.
Now (precisely 14 days after fitting them) we're up to our eyeballs in snow and the temperature at dusk today was a balmy -18.5
oC. God only knows what it is now. If I walked into the garage and said, OK Andrew, who's right?, I want rear ones as well, he'd shuffle in embarrassment and fit them.
But what would I actually say? What defect in performance would I point to to justify the request? The instability attributable to the mismatched tyres is fairly slight, and since the whole set-up feels several million per cent safer than the summer tyres, saying it wasn't safe would be ridiculous. The stunt I pulled this afternoon turning out of Broomlee Mains was completely ridiculous, but a Land Rover couldn't have done it any better.
That's my problem. The desire for a full set of winter tyres is at the moment entirely theoretical, ideological, purist if you like. Yes, it's "better". But I can't point to any actual problem I'm having with the half-setup to justify doing anything. "I want to drive like a raving lunatic in the snow" doesn't really seem like a sensible attitude, and it wouldn't even be true.
Why am I complaining? I'm not complaining! I'm ecstatically happy!
Did I mention I was ecstatically happy?
Rolfe the ecstatically happy.
