Portawalls, sometimes called slap-ons, Mickies, fake white walls, etc, available in a variety of wheel sizes and widths were originally designed to work on bias ply tires some 50 years ago, not today's radials. Bias tires have a flat rigid sidewall, and a much higher profile (aspect ratio) than radial tires. There is a lesser likelihood of them adhering properly to a radial because of the radius and flexibility of it's sidewall. The lower the profile of a radial, the less likely you will be pleased with the results. Larger radials with a 75 profile seem to work fairly well, but we do not recommend trying them on many of today's popular 70 profiles and smaller. For radials, we suggest the narrower widths, so they won't extend beyond the radius of the sidewall.
Installation is critical and the sidewalls have to be extremely clean to increase your success rate. We recommend a de-greasing agent, not a solvent be used to wipe between the tire and the rim to ensure that the area is very clean. DO NOT use a soapy compound, or the portawalls will slip out during re-inflation.

Portawalls are NOT returnable, unless you've selected the wrong wheel size and they are unused.
