Lester Tires is an American brand that has supplied crossply and beaded-edge tyres to the enthusiast market for many years. Its products cover many different sizes and patterns of pre-War and post-War car tyres.

Lester’s straight-sided tyres are a recreation of the tyres developed in the US to replace beaded-edge tyres. The Straight-sided system uses a flat-base wheel rim, and were attached with collapsible rims or detachable side flanges. They generally come in quite large diameter sizes, and some European car manufacturers experimented with them. The tread design is very simple, with a rib pattern.

This 36x4.5 Lester Straight sided crossply tyre fits a 27" wheel.
