My mondeo came with linglongs on it, to be honest I pushed it pretty hard and couldn't get them to slip. Then again I've only got 125bhp under my right foot lol.
Nankangs are actually a good tyre, people give them a lot of shit but for a tyre to use on a daily, they are quiet, last a long time and grip well. I don't really rate toyos at all, they are another budget brand and not a good one imo, I wouldn't touch Avons either, way too soft.
Best tyre I have ever used though is continentals, pricey though!
