The narrow Plus 4 uses 185/70s. With this size, clearance is tight against the top spring mount at the front, but ok at the rear.
The later cars have a fuel tank which is taller and mounted further forward, so clearance to the diff cover plate is much reduced.
I wonder if the narrow Plus 4 has the lowering blocks that the Sport has. It may be that simply removing the Sport lowering blocks and fitting shorter U bolts could give the clearance required?
I've just bought 165/80 x 15 T Trac2's after reading reports from Heinz etc. My 2012 4/4 Sport has lowering blocks and I'm 99% certain 185/70 x 15's would have rubbed on the front edge of the rear wing, especially as there is about 5mm less clearance on one side than the other.
