According to the Metropolitan Pit Stop Catalog:
All models up to Serial number E-57897 came stock with 5.20x13 tires.
All models beginning Serial number E-57897 came stock with 5.60x13 tires.
"*IMPORTANT! Using the wrong size tire can cause the front wheel spindles to break! The spindles are hollow and susceptible to flexing-cracking-breaking when stressed with a greater static/dynamic load than intended by Metropolitan design engineers.
The radial tires we (they) sell for your Metropolitan are the correct size plus provide all the advantages of radials: Better stability, less "wandering" improved ride, better breaking (sp), reduction of road noise, less roadshock & vibration, improved wet & dry traction, longer tread life. These tires are similar in profile, size (diameter, width), weight as original Metropolitan tires resulting in a similar-to-original load on the suspension and front wheel spindles."
Kip Motor Company says:
NOTE: 540 Series cars were originally equipped with 5.20 x 13 bias belted tires.
560 Series cars were originally equipped with 5.60 x 13 bias belted tires.
WHEN USING MODERN TIRE SIZES: 145/ 80 R 13 is approximately equivalent to 5.20 x 13 (bias or radial); 155 / 80 R 13 is approximately equivalent to 5.60 x 13 (bias or radial); Radial tires provide greatly improved ride and handling.
TECH NOTE: Use of an improper size tire may result in damage to your car.
