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 (Now gone)
2014 Ford Bmax 1.0 ecoboost ( Gone but what next )
2014 Ford Focus 2.0tdci Zetec S (Gone,but what a car)
2020 Ford Fiesta ActiveX 1.0 Ecoboost
2024 Skoda Kodiaq 1.5 Tsi SEL

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.
