Dạ thưa bác, vì bác quote bài em và yêu cầu nêu dẫn chứng nên em xin trả lời bác là bác có thể google về vấn đề này ra rất nhiều. Tuy nhiên ở đây em xin trích dẫn nguồn từ chuyên trang runflat của hãng lốp Bridgestone phần Q&A như sau: (

Q. Do tyres with the Bridgestone Run-Flat Technology have any effect on comfort or other performance when compared with standard tyres (handling, mileage, etc.)?
Vehicles fitted with Run-Flat Technology have specially tuned suspension to compensate for the increased tyre rigidity that is a feature of RFT tyres. All tyre performances though (comfort, mileage, handling) have been optimized for your vehicle in accordance with the requirements of the vehicle manufacturers. Meaning Bridgestone tyres with Run-Flat Technology do not perform differently from conventional tyres, but add on important safety value, which is keeping control and traveling you safely in case of puncture.
Để đa dạng hơn không mọi người lại bảo là hãng lốp muốn bán lốp đắt nên nói thế thì em xin dẫn tiếp nguồn từ hãng sửa xe vậy: (

Can you fit normal tyres to a car set up for run flat tyres?
No, you should not put non-run flat tyres on a car set up for run flat tyres. There are two main reasons for this:
- Because run flat tyres are very hard due to the reinforced sidewall, the suspension on the car is set much softer so the ride is normal for occupants. If a normal tyre is fitted then the ride will feel very soft, the handling will be adversely affected and could present serious safety concerns.
- As the car will not have a spare or any other way to deal with a flat tyre, if non-run flat tyres are fitted, the car will be stranded if a puncture does occur.
Can you fit run flat tyres to a car not initially set up for run flat tyres?
No you should not fit Run flat tyres on a car not originally set up for it.
- The car will not have a tyre pressure monitoring system installed and consequently the driver will have no idea if a puncture occurs and will continue to drive normally with catastrophic ramifications.
- Run flat tyres are much harder and therefore the ride will be much harsher and it will affect the handling and feel of the car.
Vấn đề cảm giác lái thì tùy người lái thôi em không có ý kiến gì
Bác bảo RFT vẫn đứng đường như thường em cũng không định tranh luận. Còn em chạy RFT chưa từng đứng đường kể cả khi lốp bị miếng tôn tam giác xiên xịt hết hơi trên đại lộ Thăng Long, em vẫn về nhà (đi thêm khoảng 25km nữa) ngủ dậy sáng hôm sau ra hàng lốp để vá.
