What's a slop ?

It seems Yeovil is pretty far south....I doubt you get much snow/ice to be concerned in that regard ?

But really...spend some time on Tyre Reviews, Jon has great videos and tests with a multitude of tyres, in many many conditions. That may help make a better judgement

But the likes of a Michelin PS4 or the new PS5 would be hard to beat as an all rounder. Although obviously don't expect wonders in snow or ice.

That far south, it would seem hard to bias towards an all weather/season tyre unless you do a lot of driving in colder climates. Although Michelin Cross Climate 2's seem to be among the best of that bunch, but obviously they won't be great for hard fast driving in warm summer
