Did you hear about Ford going Metric in 1979 and mounting 15.4 inch (390 millimeter) rims and tires on the 1979-84 Mustang, Mercury Capri, and Thunderbird Turbo Coupe? Called the TRX system, but commonly referred to as WTF!


Metric 390mm TRX wheels with Michelin P190/65R390 radials were a first on the Mustang for 1979 and were in continuous production through 1984.

Michelin invented the steel-belted radial tire, which it introduced in 1946. That turned out rather well for them. In the early seventies, anticipating the trend to ever lower-profile tires, Michelin made a bold gamble to reinvent the genre, with a proprietary metric wheel-tire combination that was not interchangeable with conventional wheels and tires.

Michelin’s ideas behind the TRX tire were very valid. As tires moved to lower profiles, their smaller sidewalls naturally resulted in substantially stiffer rides. Michelin, being based in France and so associated with the smooth-riding French cars, looked for a compromise, to gain the performance benefits of a low aspect ratio tire and maintain good ride quality.

The solution was the TRX flange and tire (the TDX was a similar design but also included limited run-flat capability). The wheel flange is angled outward, and not so deep. That allows a more gradual transition from the tire bead to the sidewall, maximizing its ability to flex, even with a limited sidewall height.

Fine in theory, but as with all proprietary bullshit, it's not worth the expense compared to the contemporary competitors products that are less expensive (hello Betamax by Sony - vs VHS)

It seems the only tires available in the USA for replacement were expensive Michellin TRX , making no one very happy about this dipping into Ford of Europe parts bins.

WHY for the love of Mustangs did they do this unholy crossover to European standards and screw over American Mustang fans?

Some stylist dweeb from Ford of Europe design studio, named Jack Telnack, was sent back to Detroit, (probably for annoying the design studio people in Europe) and he'd believed it was time for a fresh-faced Mustang—a new breed. It was going to be a totally new Mustang built on a European-style platform known as Fox. The "Fox" name was based on what Ford envisioned for this new platform using the German Audi Fox as a benchmark.

the 1967 Nickey/Bill Thomas Camaro Wheel, made by Rader




In December 1966, a gentleman in California purchased the car, originally an SS350, new for his girlfriend. The relationship ended sometime in mid-1967, and he got the car back. He wasn’t satisfied with the performance of the small-block engine, so Nickey Chevrolet, then “the largest performance parts dealer in the country,” says Dean, commissioned Bill Thomas Race Cars to convert the car to Nickey big-block status.

Bill Thomas Race Cars would end up doing just a small number of 1967 Camaro big-block conversions under the arrangement with Nickey. The cost of shipping cars from California to Chicago made the partnership cost-prohibitive. Nickey then turned to Dick Harrell to perform the big-block conversions, and by the end of 1967, Bill Thomas Race Cars was no longer connected to Nickey Chevrolet.

While most of the Bill Thomas conversions used 427-inch Corvette engines, this car received a “cheater” 427 engine that came in at 467 ci. The car was also equipped with a 12-bolt Posi rear with 3.07 gears. Best guess is that the owner was interested in high-speed highway cruising instead of quick acceleration. A “Bill Thomas Traction Kit” (a set of traction bars) was also installed, as was a set of “special mufflers,” a set of Rader wheels, and a set of “Perrelli” (sic) tires.

can you name a rim manufacturer that has made a set of wheels/rims that went over 600 mph? Cragar can


In 1970, The Blue Flame became the world land speed record holder.

Gary Gabelich shocked the world by reaching speeds of 622.407 mph in his Blue Flame, rocket powered vehicle using custom high-speed aluminum wheels built by Cragar, on the salt at Bonneville
