1) How long do tyres are really safe to be use. Is 5 years the max?
2) so im using an old rwd car which its stock wheels are wider in the rear. Right now i have 205/50/16 in front and 225/50/16 in rear. Problem is the rear tyre size is quite difficult to find. The one im using ps3. Which size do you suggest i change to or just stick to Michelline ps3/4..other brands didn't have this size😢
