235 is the tyre width it doesnt affect the wheel track because the measuments are taken from the centre of the tyre. The law is you cannot exced the wheel track by 25mm and the outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter wheel and tyre combination specified for the vehicle and not more than 15mm below the smallest diameter wheeland tyre combination specified for the vehicle.
