Daffy, I'm sure that I'm not the only one on here who would be very interested in a report from you once you have had a chance to drive on a variety of surfaces. Please come back at some point.
Markymark. Hopefully, you will see this - I should have asked you a question when you posted lat year - are those Cross Climates on a 2 or 4WD van and what do you think of them now that they have (hopefully) had a bit more use.
Personally, I'm still looking to replace my tyres with all seasons but my conscience just won't let me bin the tyres currently on the van that have still only got about 2000 miles on them (I replaced the 16" wheels with a set of delivery mileage Devonports with original tyres).
