, RANGE of steel cord, radial ly lorry tyres — 12000 — has een announced by Firestone.
Made entirely with steel, the yrres have four steel belts nder the thread, which are aid to improve resistance to ufs and punctures.
Firestone says the tyres ave been designed to be Tess free, that is having the ross sectional profile oinciding with the natural .ee curve of the steel strands. This results in no stress on the fabric when the tyre is shaped and cured, which in turn gives a greater uniformity of profile.
In addition, rolling resistence is reduced, which should result in improved fuel consumption.
To ensure quality in production, Firestone will be regularly analysing the tyre section as well as checking the tyres dynamically and with Xrays. A written guarantee is to be issued with the tyres stating that they can be retreaded or remoulded at least once. Tyres which have been remoulded/ retreaded will be stamped HMR before being returned to service.
