Goodyear were anti radial tyres
Ford motor company had radically changed the way
that cars were to run on radial tyres. Starting off in the late
sixties by putting radial tyres on their new Lincoln models had set
the tone for the future of radial tyres in the American auto
industry. By 1973 General motors had started to follow Ford by
introducing radial tyres with improved car suspension onto some of
their new models. The GM cars had about 11% of their cars fitted with
radial tyres, and by now 26% of ford cars were fitted with original
equipment radial tyres mainly from Michelin tyres.
By the mid seventies this figure had risen to 90%
a by now most cars were equipped with new radial tyres. Not all the
tyre companies were still convinced with the radial tyre, the most
prominent was the Goodyear tyre and rubber company. Goodyear were
reluctant to change all their factories and tooling equipment to
enable them to produce the radial tyres that were now becoming very
popular. This was going to cost Goodyear tyres millions of dollars
and they were reluctant to change strategy. Indeed in 1967 launched
a new tyre product to the World called the Polysteel bias belted
tyre. I remember these tyres being introduced here in the UK, when I
worked for Briggs tyres here in the UK. It was at a time when all the
leading tyre makers were trying out new products and this new tyre
from Goodyear was no exception.
Goodyear s main problem with the radial tyres , is
that they lasted too long and would have meant a reduction in tyre
sales. The new polysteel tyre was made with polyester cords and
fibreglass belting instead of steel, as in Michelin tyres. Goodyear
promoted this new tyre very strongly and many of the American car
makers started to introduce this new tyre to their models, indeed by
1970 ,85% of American cars were made using bias belted tyres in place
of radial tyres. I remember the special Goodyear promotions here in
the UK, but the bottom line is that the new tyre did not take off
here in the UK, and as far as I remember did not compliment the
suspension of the European produced cars. It was a different
situation in America with General motors buying a staggering 30
million tyres a year, meaning that for the time being bias belted
tyres were back with a bang.
The Americans could not make radial tyres ?
The bottom line is that the American tyre
companies could not make radial tyres, especially steel belted radial
tyres. They did not have the technical knowledge and the early
attempts to make steel belted radials was abysmal.

Michelin tyres were not prepared to share their
superior knowledge about the way that steel belting was produced and
how the steel was processed to stop the steel from rusting when
penetrated by a puncture and eventually rusting the whole steel belt
until the total tyre broke down causing a blow-out. Both Goodyear
and Firestone tyre companies came a cropper trying to make steel
belted radial tyres but this is for another blog.
