Well, that X reg Ford Escort Ghia 1.6 5 door - our first brand new car, was a stocked car, that came with wide low profile tyre size option 175/70 no less!!
As it came without a rear wiper, so I bought a genuine Ford rear rear wiper kit for it and fitted it over the Christmas break - Santa brought it! It was more than a bit worrying measuring up the exact correct spot to drill a big hole in the rear hatch lid of a 6 month old car!! Measured many times, looked at the spot where to drill, went back into the house and have a cup of tea, repeat a few times before getting brave enough to "just do it", it all worked out very well, the worry was that while there was no hole on the rear hatch, there were punched out holes on the inner frame where the motor etc was mounted, so not much scope for errors!
