The idea of just introducing much more wheels to a car to make go a lot quicker is a single that’s so simple, it would seem stupid. But extremely major engineers, like individuals at the Tyrrell F1 workforce in the ’70s, have place major considered into creating it do the job.
The crew at the Pushed Media YouTube channel has posted the most up-to-date in its collection of over-the-top tire assessments to ascertain if basically including 4 wheels to a Caterham 7 will make it more quickly. Dubbed the Eighterham, it options duallies at all four corners.
To make it, the team simply just bought some steelies, welded them jointly, and mounted them to boost the quantity of rubber on the highway.

Even though the wheels are undeniably wider, they’re also really a bit heavier. In spite of the actuality that they do not actually weigh the wheels, the team implies that the additional mass is substantial.
So can a significant increase of rubber on the highway counteract a important enhance in unsprung weight? Properly, on observe, the response is of course. With a set of typical Avon tires on the auto, it completes a lap of their take a look at track in 31.6 seconds. With the new double-width wheels, though, they handle to set a lap time of 31.1 seconds, slicing 50 % a next off their time, which is a really outstanding feat on a keep track of that limited.
Off the monitor, nevertheless, the car or truck is a little bit of a nightmare. Despite the fact that a Caterham is by no signifies a large car or truck, the Eighterham struggles to change as sharply as it after did. It even has a challenging time fitting into parking spots simply because of its prodigious width.
As opposed to the F1 tires that this crew earlier tested, although, the duallies basically can be applied on the highway and do not call for tire blankets to be handy on the observe. They also price drastically considerably less, so which would you get?
