True or False: Radial Tires typically allow determination of under-inflation by visual inspection.

Radial tires are designed with a specific construction that makes visual inspection for under-inflation less effective compared to other tire types. The way the tread and sidewall are structured in radial tires often means that they maintain their shape well even when they are under-inflated. This ability to retain the appearance of proper inflation can lead to drivers not noticing a problem unless they check the pressure with a gauge. Relying solely on visual cues can be misleading, as a tire can look adequately inflated even when it is not, leading to safety risks such as reduced traction, increased wear, and potential tire blowouts. Therefore, the statement regarding the capability of visual inspection to effectively determine under-inflation in radial tires is false; regular pressure checks with a gauge are the recommended practice to ensure safe tire conditions.
