Just be aware that the pressure shown on the
tire sidewall is
NOT the recommended pressure for a Spyder, it's the
MAXIMUM PRESSURE for the tire IF & ONLY IF the tire is being subjected to carrying the MAXIMUM LOAD that's also shown on the sidewall! :lecturef_smilie:
There should be a Tire Placard somewhere on the Spyder itself, that shows the OE Spec Tire sizes and the recommended pressures for them, and
THAT'S the '
one size fits most' pressure that you want to start out with in your OE Tires, adjusting up or down a little (maybe 2psi-ish?

) if necessary to suit your particular requirements/circumstances!

. On
some/most(?) earlier model Spyders that came out with the rectangular swing arm (including F3T's & F3L's) the Tire Placard is usually found on the Left Hand Side (while sitting on the Spyder) Swing Arm just to the rear of the swing arm bush/pivot. On those F3's with tubular swing arms, IIRC I believe
most had it under the LHS service panel below the handlebars. Hope that helps some... :dontknow:
