I have recently purchased a set of Firestone Firehawk R4S tires.
27x8.50-14, load range C, 1515 lbs at 50 PSI.  I paid $63 plus about $30 for
shipping from Tire Rack.  Not only do they look great on my tall-sitting '85
Westy, but they ride very nicely.  My speedo now reads about 3% low, but the
taller tires seemed to complement the engine and the vehicle.  My steering
is now so light in parking lots that I don't miss my power steering any
more.  They are quiet.  I don't notice any power loss, not even on the
highway.  I mounted them with the white letters to the outside just to get
that SYNCRO SENSATION!
