Ahh cheers for explaining it i had no idea 75 was the percentage of the width I think im going to move up to 15 inch rims as it gives me more choice of tyre and more availability of quick replacement if needed
that's what i did it also gives you the chance of upping the gearing a bit if you have modified the engine for more power
