No affiliation, but given the often local scarceness of "proper" 14" tires,
I thought I'd pass on the Boss Tire of Moncton, New Brunswick stocks the
Hercules G4000LT 14" Light Truck Tire. I just bought 4 from them for $89
each. A few pictures/particulars at

They don't list them on their site at bosstire.com, but somebody on staff is
an ex Westy owner...
8 ply D-rated 185R14C. Incidentally, anyone know what the "C" stand for ??

YMMV :)
