What should you remember when putting winter tyres on your car?

Your answer is correct because when fitting winter tyres, you must check the tyre inflation pressure according to the manufacturer's guidelines to ensure safe handling and tyre performance. Additionally, it is important to observe the maximum speed allowed for winter tyres, as they often have a lower speed rating than summer tyres. Lowering the air pressure below the manufacturer’s recommendation, as suggested in option 3, is not correct because incorrect pressure can impair driving safety and tyre wear. Always follow the manufacturer's specifications for both pressure and speed limits to maintain optimal safety in winter conditions.
