Dear friends, I would appreciate your inputs in regard to tyres of my FIAT Uno 1999 being put into experiment. In my car I can see that the existing tyres are 155/70R13 Bridgestone and recently I met a person who was selling off tyres 175/70R13 JK Tyre. Can anybody suggest me if the tyres 175/70R13 will fit into my Uno and also was wondering if I can use these 175/70R13 for the rear side only as I believe that If placed on the front too it might rub against the bumpers and the fenders while turning and or in potholes. Please advise if it is possible to change all the four tyres to the 175/70R13 or the rear ones replaced with the 175/70R13 and front ones left with the very same 155/70R13 will suit the looks of the vehicle as I am trying all possible efforts to increase the ground clearance at the back end as the silencer joint underneath hits the speed breakers when my family (2 in front and 3 in the rear seat) travels together in this car . Also please advice if the experiment will be safe to do as my vehicle runs mostly on highways tossing anywhere between 100-140 Kmph.
