The idea of rotating the tire was to ensure a balance grip & wear level among the 4 tires... hence better stability & handling

Different people has different mentality.... However I would advised people to change all 4 tires at the same time if possible.

And I understand not everyone can afford to change all 4 tires at the same time.... in that case, I would strongly recommend that the new tires should always goes to the rear (never to the front). I wont waste time explaining why, just go to YouTube and search for new tire, front or rear.... you'll get the reason behind it...

Just a reminder to all... Tires are the most important component on the car. Its what keeping your car on the road.... Get the best tire that you can afford. Think of your safety & the safety of your loved one in the car with you...
