Hi all sifu,

I want to ask, can i replace my current run-flat tires to regular tires for my Mercedes-Benz B200 W246 R18 wheels?

off course you can. in fact the car will be more comfortable without RFT

Sudah tentu boleh

Yes. I use ps4 for my w246

So do you use the pressured can chemical repair gel or tyre repair rubber thread or conventional spare tyre or depend on free insurance tow? I am anti RFT 🤪

Thanks sifu, so i can fit ps4 michelin regular tyre for my w246? It will fit the wheel correct?

if got similar size, of course can, tyre sizing is same across the industry.

the workshop will help you check if you're not sure how to.

yes, if you are using same as mine which is 17", our size is 225/45/17 .

price around 4xx per donut.

Just curious, can we make it the other way? Using run flat tyre on non run flat tyre car.

Technically yes. But it’s a big not recommended. Run flat need to come together with pressure monitoring system. If you do not have the system, it will bring danger to you when the tyre puncture without you knowing it while driving. Your tyre will basically burst once the sidewall rupture

Alright. Thanks for the explanation. Learn new stuff today

Can you elaborate further? Because runflattires should not burst if under inflated. In fact isn't that their selling point? The run flat tires are reinforced so that it can run without any air at all.

You’re partly correct. But RFT only able to withstand specified mileage before total failure. As an example, a pirelli rft, can only last 100km with 80km/hr speed without air. Then it will deteriorate. The selling point is that you can still drive until your next workshop.

upvote. This is useful information
