@MrTesco. Surely it depends on the weight/axle load rating of your vehicle. Is it a T30 or T32? I recall that recently it has come up that Caravelles can be constructed as either.I've seen a couple of posts about T32's having 17" wheels but my Shuttle came with 16" steels would this be right or have I got the wrong wheels on?
@MrTesco could you please post up a photo of your under-bonnet load/axle plate or the figures. @T6AL has a gross weight listed on his V5 of 3080kg which would appear to conform to T30 equivalent van or Kombi. However, only a dealer can tell you from looking up the build sheet what elements have been used for suspension etc. as the Shuttle is a separate line and not a load carrying vehicle. Caravelle wheels from the brochure are 16" for the 150ps SWB and 17" for the 150ps LWB and 204ps LWB.Mines a T32 Shuttle

It seems like a careful check is required of spec and build sheets to see just what wheels should be fitted as standard to the Shuttle as only 16" are listed in the brochure for the 84ps SWB with 17" for all others, alloys are an option in the current March 2017 brochure.
Sorry if this is garbled but it's way late.
T32 only come with larger brakes if its the larger engine also (180/204) although they do all come with 17" wheels usually devonports
The passenger carriers dont conform to the T28/T30/T32 setup that vans and kombis do.
Yours is in between and think this is why the wheels are different
T32 has axle weights of 1710 / 1720
