Negetive things about Run Flat Tyres(RFT)?

Any new technology will have negatives and RFT is no longer an exception.

See below what I have for you. I have got this from internet.

• They are difficult to find on the replacement market. Few dealers stock them•
• They are expensive.
• “Most models” cannot be repaired.
• They ride rough.
• They tend to generate pattern noise as they wear.
• “Long tread wear does not seem to be a characteristic of these tires.”
• The special mounting/demounting equipment may not be found at all tire shops.

Advantages are many which all of us know !!

Cheers !!
