    I would like a ruling from the Series Manager.  There are now several tire/wheel options from NSR for the F1-86/89.
    REAR TIRES:
    OEM/original (19.5 X 13) NSR-5284 (Supergrip 25shore?) 5284 (Ultragrip 15~20shore?)
    Alternative (19.0 X 13) NSR-5287 (Supergrip) 5288 (Ultragrip)
    Both 19.5 and 19 OD fit the NSR F1 wheels with a 13mm Diameter Rim/bead.

    FRONT TIRES: NSR-5290 (16X8) NSR-5291 (17X10)  Zerogrip (fit the same wheel-5020)

    WHEELS
    REAR OEM NSR-5021 have an “air-system” Rib/Nib. 13mm OD x 10mm width
    NSR-5027 –  Solid Rib/Nib. 13mm OD x 10mm width
    NSR-5022 -“air-system” 13mm OD x 13mm width
    NSR-5026 -“air-system” Drilled – 13mm OD x 13mm width

    FRONT OEM NSR-5020 solid Rib/Nib. 13mm OD x 8mm width

    At 4-years old in Pensacola I repaired my steering linkage on my Ford Pedal-car. Dad later converted this car to a Blue Angel with ailerons and elevators with a working "stick/yoke"; the rudder was controlled by the steering wheel. I like all motorsports - I grew up going to a NASCAR Feeder track with Sportsman and Modified classes, and was lucky to attend drag races in 1970 at Orange County Raceway. My first solder-iron was a Christmas gift at 9yo; I modified T-Jets to be AFX spec before AFX Cars were in local stores. I rebuilt a few tractor & car (SIMCA) engines plus transmissions by 15yo (I still have my ring-compressor and valve spring tool) I am a former mountain and road bike geek & perennial sound engineer.
