I have exactly the same wheel, colour and tyre size in an A/T on mine, difference to standard that i wondered if you have found.
1. Raises the ride height of the van by 1 inch, which IMHO is a good thing in a few different ways.
2.Required a 4 wheel tracking, as the difference before and after just in feel was very apparent.
3. Slight scrub on front wheels on the limit in turning both ways (minor)
4. Changed my actual speed from reading under to only 1mph over at 30mph
5. Spare wont fit under van so essential can of Holts tyre weld under the seat for when i don't have room for the spare in the back.
6. Very easy to see when tyre is under inflated as the tall sidewall is far more noticeable when bulging due to its height.
7. Gloss was too bling an option and matt was too dull, but satin was just perfect.
8. IMHO this tyre /wheel/colour combo looks really nice whilst retaining an understated element.
