Space saver spare

When your tires wear out replace them with run-flat tires, you can run them on zero tire pressure to the shop / dealer and you won't need a spare.  I love run-flats!

Hi.

My understanding is that you should NOT use RFT unless you have a car with Tyre Pressure Monitoring (and the correct rims) as it is not obvious when you have a puncture and can therefore be dangerous if you continue to drive at speed with no tyre pressure.

Hi John,

I had a pothole blowout 18 months ago.  I checked the tyre in question and found that the rim was safe and undamaged and there appeared to be enough strength in the tyre to allow me to drive safely the mile and a half home at 10 mph.

Regards,

Peter.

Hi Peter

That is fine because there was an event that made you stop and check, then proceed at slow speed to get home. The problem when used without TPMS is where it is a slow puncture and you come to need high speed braking and/or steering response only to find the tyre is actually deflated!

In that scenario I am pretty sure the insurance would be an issue as you had modified the car from standard.... If RFT are not specified in your handbook as a fitment my advice would be do not fit them.

Kind regards

John

Hi John,

What you have said is so true.  There are so many people who allow their tyres to wear till the last minute.

I am regarded by some as a nut case for changing my tyres while there is still "some life in them".

I was coming back from work in 1963 when an  e-type passed me on the Chestier by-pass with on of his tyres having bare canvas.  Luckily I was driving a fast motorcycle and I was able to catch him.  He was horrified but I think he learned a lesson!

Regards,

Peter.
