the 245's obviously have a higher wall profile compared to the the front as there not stretched as much, but i dont think it looks bad at all.
u may have a different outer lip to my old ones chop, hence mine might be slightly wider and thus the tyres sits more comfortably on it.
Sam also has the extra wide dishes for the rear if he wants to take them to 10's, which i was going to do at a later date and fit 265's, or maybe large.
Lucky i did all the arch work as the 10's go under quite nicely.
