hi all I will start by saying I have done a search for the answer but I am really struggling to get an answer.. I am buying my dad new tyres for his disco 2 . it is on 255 55 18 and looking to put on some a/t maybe something like a general grabber. I would like to take tyre slightly bigger from a 55 profile. but I don't know how big the disco 2 will allow without any fouling. (maybe a inch or two will be enough, just make it stand out a little bit more). it isn't used for off roading 95 % road and 5% on fields with a trailer of wood... any help I could get would be great. also may I add it is a es premium model so has the mud flaps and side rails, I don't know if it would make any difference on tyre clearance.. thanks for you time
