Rotated or swopped back to front? Check on the tyres side wall for the word 'Rotation'. There will also be an arrow or indicater for the direction of rotation when driving forward. They must be on the correct side of the vehicle and rotating in a forward direction. The age of your tyres can be found by reading the DOT code on the tyre wall. You will see the word 'DOT' next to a box with four numbers within it. The first two numbers are for 'the week of the year', whilst the second two numbers are for 'year of manufacture'. ie. DOT 2414 would mean twenty-fourth week of 2014, which is when the tyre was produced.

Odd sound after tire rotation?
I once saw a sentence: 


  I will go to a restaurant for pie.


Native speakers didn't correct this sentence. I don't know why. I would say "I will go to a restaurant to eat a pie". But maybe that sentence was right. Could you please explain to me what that (first) sentence means?
