Could anyone tell me the largest size winter or all weather tyre that will go on an 18 inch standard alloy rim please ??? I`m running 235\60\18s at moment but need to get a full set so was thinking about up sizing maybe ???

I'd stick to the standard size myself and not mess with oversized tyres . My Fl2 has Pirelli Scorpion Atr's fitted and I'm more than happy with them .

Mark 2009 FL2 TD4 SE (Sadly gone)
2007 FL2 TD4 GS (The wifes , gone after 8 great years)
2012 FL2 SD4 SPORT LE(Gone and missing it)
2015 DISCOVERY SPORT 2.2SD4 HSE (For now ?)
2014 Ford Bmax 1.0 ecoboost ( Gone but what next )
2014 Ford Focus 2.0tdci Zetec S

Don't think they do 235x60x18 scorpion atr according to pirelli website. MY 09 GS manual in Lago Grey, Wood Co arm rest and side bumper strips - now sold.
