LOLOLOLOLOL :D You're really running out of steam here Phil, and just digging yourself deeper and deeper in your pit of foolishness! :D
Of course the Lexus won't be a good tow car from driving across muddy fields pulling things - it wasn't designed to be! But we aren't talking about an IS200 in that context, and you'd be even more foolish than I already think you are if you are trying to turn it that way. We are talking about fitting winter tyres to a car that you yourself say is rubbish in the snow, in an attempt, a hope, or as some have stated, a fact, at making it better at driving in the snow on roads - not fields, or towing
However, with that said, seeing as most winter tyres are designated M+S (which, as you're an expert, you know this stands for mud and snow), don't you think there's a possibility that M+S designated tyres might give some extra grip in the muddy fields?
Hahahaha Phil. You've absolutely proven you are completely here for the argument, no matter what the subject or points are - and when your points are countered and your foolishness revealed, you try to change direction to continue an argument. And that my ill-learned friend, is what makes you the biggest fool of all! :D
(still chuckling :D )
