Portawall White Wall Tire Inserts (sometimes referred to as Port-o-walls, white wall inserts, slap-ons, Mickies, fake white walls, etc.) ~ Firestone Tire Style White Wall Tire Inserts make a great accessory for your Custom Car, Truck, Hot Rod, Rat Rod, Harley Davidson or Custom Motorcycle.
Portawall White Walls are available in 10″, 12″, 13″, 14″, 15″, 16″, 17″, 18″ and 21″ for Cars, Trucks, Mini-Bikes, and Motorcycles and in varying widths to meet your needs.
Portawalls were originally designed to work on bias-ply tires some 50 years ago, not today’s radials. Bias-ply tires have a flat rigid sidewall and a much higher profile, or aspect ratio, than radial tires.
The lower the profile of a radial, the less likely you will be pleased with the results. Larger radials with a 75 profile work well, but we do not recommend trying them on many of today’s popular 65 profiles and smaller. For radials, we suggest the narrower widths, so they won’t extend beyond the radius of the sidewall. A set consists of (4) pieces. For best results, follow all steps of included instructions.
