They look good! I'll be interested on how you find the wet weather handling as I am looking at fitting the 275/45/20 V to mine this winter There is no replacement for displacement - W O Bentley

I have used these tyres for years now in all incarnations from the original A/T’s up to the current version. I have never had a problem with them in any conditions. If you drive according to the weather and your abilities you’ll be fine. Current: 2010 RRS 3.6 TDV8 HSE

I found the 255/55/19 got a little bit slippy in the wet as they wore down below half tread depth. It was only if I was a bit aggressive with them, to be honest, but a hard brake would get the ABS cutting in where when new it didn't, strangely.

They still worked well off road when worn, by the way. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
