195/50/15 is the best way to go, £35 to £50 fitted a corner depending on what you go for, 4 tyres for under £200 is pretty good, if you get some goodyear F1's or soemthing like that. cant go wrong, iv got few sets of F1's, paradas and now toyos in that size.
havnt known 195/50's to rub on the rear arches, who comes up with all the arch rubbing stories!?
