Do wider tyres give you more grip? The logical answer would be yes, the wider the tyre, the more rubber in contact with the surface, but it actually isn’t that simple.

As a tyre gets wider, the footprint of the tyre changes. While the footprint does get wider, it also gets shorter, and how the tyre changes under camber and load is altered too.
Instead of worrying about the theory of wider tyres, I decided to actually do the test and let the results speak for themselves.
It was a complicated test, and after nearly a years planning, and a large amount of help from Goodyear, the resulting video should tell you all you need to know about fitting wider tyres!Tyre sizes on test are 225, 255 and 285 wide 19 inch tyres. Each tyre has a slightly different profile, so the final sizes are 225/40 R19, 255/35 R19 and 285/30 R19.
