The straight answere to "will they fit is yes and no!
You can bolt them straight on, but you will find they will catch badly when you turn the steering wheel or the axles articulate unless modifications are made to the suspension/body/steering. The tyre dimensions relate to the carcus of the tyre, not the outside of the rubber, so road tread tyres would probably fit better then serious mud terrain tyres.
In practice the answer without modification is no.
PS. this is not an uncommon question and there is a search fasility on this forum
You will find there is already a wealth of information on the subject just waiting to be read.
