I'm taking my 19" Duratracs off the car and fitting the 20" rims on that it came on but wondering what tyres/sizes people are using for best results, it will be mainly used on the road but thinking of wet grass and mud so don't want to get caught out with the van. My current thoughts are 275/45x20 and either GG at3's or Pirelli Verde All Season, any help would be greatly appreciated and sorry if this is in the wrong section.

Hi,
standard size, our L494 Dynamic had PVAS 275.45.21 and tintented many times we no trouble at all

Thanks for that, just realised reading your post mine is a 2012/62 plate so L320.

L320 20" are 275/40/20 as standard. A few on here have fitted 275/45/20 and have reported a more compliant ride due to the increased sidewall height. I think that's the way to go providing your insurance company don't call it a modification.

I have 275x45x20 Grabber A/T3's fitted, gives a bit better ride comfort and with a combination of the terrain response and the tyres you should never have any problems with your wobbly box. I have a 2T Buccaneer and it just sits behind and does as it's told no matter what..  Current: 2010 RRS 3.6 TDV8 HSE

Thanks guys, size is sorted and I think it's going to be GGs as they are getting good feedback too.

The Grabbers are fantastic tyres and General is a brand name of Continental tyres so a quality product. My mate owns a tyre business/ garage and he runs them on his own car, that’s always been good enough for me! Current: 2010 RRS 3.6 TDV8 HSE
