I m fitting low-profile tyres to my car – what should the tyre pressures be?

That depends on what profile you are fitting, but generally the pressures will be higher than those for your standard-fit tyres. As the profile of a tyre gets lower, so does its Load Index – the amount of weight it can support – and that can mean as much as 100kg difference between the standard tyre and an aftermarket fitment. In extreme circumstances this might result in a set of low-profile tyres being unable to sustain the weight of a fully-laden car; this is illegal and dangerous, and will also damage your tyres.
