What I’ve learned so far. Wheels need to be load rated for axle weight = Easy. PCD 120 x 5 =600 Easy. ET or offset is not a complete indicator of fit. Some wheel spokes are more “dished” than others, meaning even wheels with the same offset may not clear your brake calipers. So, I suspect that the only way to be certain is to fit the rim and tyre to see what happens which could prove expensive if wrong. Alternative is to determine if people with EXACTLY the same van have fitted EXACTLY the same wheels. I want some gloss black 10 or 12 spoke 18”x8J alloys to fit my 2015 T5.1 2000cc bi turbo diesel with the larger calipers. So, if anyone can give me some good suggestion please fire away.suggestion
