I'm just struggling to work out the best size though. And I've noticed some people get bigger sizes in the rear too.
My Alloy's are: 7x16. I was originally thinking of using 215/60/16 all round.
I've not changed the springs (replaced all 4 shocks last year), so i'm pretty sure everything should be the original spec. Would appreciate any info though.
Cheers.
Here's some pictures of the wheels and tyres currently mounted on my van (current tyres are 205/55/16):
