bro, ditch the rft's and get normal tyres.

i prefer the rft coz of safety & convenient.
one sunday morning, i didn't realize that one of my tyres was flat. was driving on normal highway speed but the flat tyre warning didn't come out. Only after i reached the toll, the warning light came up. Still able to drive to nearest petrol station & found the rubber valve was broken. so, drove to nearest tyre shop and changed it. So, the rft did its job.
imagine if normal tyre....also changing tyre on highway is not so safe.

entirely up to u bro. for me, im just waiting my set of rfts to wear out, or an irrepairable puncture. then im switching to normal tyres.
do u initialise the tyre pressure everytime u pump air into it? might pick up rapid loss of pressure sooner if u do.
don't like the hard ride and the fact that 1 tyre costs RM1100-1200.

Yeah, I've switched to normal GY F1 Asymms a few months back when the RFTs got worn out. Bought one of those foam repair kits and a portable compressor, which I leave in the trunk.
Had a nail puncture in one of the rear tyres last week and the tyre warning light did its job. It detected the underinflation of one tyre compared to the rest. Visual check seemed to indicate that all the tyres were fine but when I tested the tyres with my tyre pressure gauge, one tyre was about 8 psi lower than normal. So, it was still drivable. Took it to a tyre shop and low and behold, there was a nail in the tyre. RM10 repair job.

Pros & Cons of Run-Flat Tyres
Editor’s Note: The following article is courtesy of our friends at Tyrepac.com. We found it to be most informative, and hence, would like to share it with you, the readers.
In recent years, run-flat tyres (RFT) have been gaining in popularity. In fact, the development of RFT has been around for some time. Nowadays, brands such as Michelin, Continental, Goodyear, Bridgestone, Dunlop, Firestone, Pirelli, Yokohama has a range of products, otherwise indicated as the RFT (Run Flat Tyre), SSR (Self Supporting Run-flat) or ZP (Zero Pressure), and so forth.
Run Flat Tyres (RFT) is also commonly known as “puncture-proof tyres,” however, that tagline is a bit untrue as RFT are not entirely immune to punctures. RFT at the punctured state (low pressure or the tyre pressure of zero state) can maintain travelling speeds of up to 80km/h for up to 80km or so.
Automakers pitch run-flats as a safety feature because they let drivers avoid stopping on busy highways and other dangerous locations. They also say they like the design flexibility they get by eliminating the space-consuming spare tyre. Even though run-flats are heavier, the lack of a spare tyre can save vehicle weight overall, helping fuel efficiency. Below we analyze the structure and principle of RFT, and its advantages & disadvantages.
Construction and Principle:
Construction of a Run-Flat Tyre
The main ingredient of tyre is rubber, but rubber itself is unable to cope with any load, thus the load of tyres mainly depend on layers of a reinforced fibre and steel wire. Rubber elasticity is much lower than fibre and steel wire, thus adequate tyre pressure ensures the process of deformation of rubber tyres will be minimal. However, if the tyre is travelling at low tyre pressure condition, the rubber will be deformed, stretching more than the strength of the fibres and elasticity limit of the steel wire. This could cause significant damage to the tyre, as the pressure will eventually destroy the interface between the different raw materials, and in more serious cases, result in tyre failure (Figure 1).
The Advantage with Run flat tyres is that they can operate without air in them, for a relatively short distance and low speeds, as their basic shape is kept by rigid components. This rigidity helps a driver maintain control of the vehicle if the tyre loses pressure (Figure 2), and allows the driver to continue driving, the pressurised air contained within the tyre supports the weight of the car. (Figure 3) However, recently tyres have been developed which are able to support the weight of the car by themselves, for a short period of time. New cars are also equipped with tyre pressure monitoring devices which warn the driver of a tyre pressure loss.
Benefits:
Eliminate the need to change a tyre in bad weather or in dangerous roadside areas.
Safety and reduced risk of accident – blowouts and tyre deflation can be serious driving risks for drivers.
Tyres can be driven on for 80 kilometres or more with no air in them enable drivers to get to a mechanic without having to change the tyre after a puncture.
Car need not be equipped with a spare tyre, resulting in more trunk space.
The absence of a spare wheel contributes to lower vehicle weight which will in turn reduce fuel consumption, reduce harmful exhaust emissions, improve performance, handling and braking characteristics.
Tyre pressure monitoring devices warn the driver of a tyre pressure loss.
Disadvantages:
RFT’s sidewall is harder than ordinary tyres, so comfort is compromised.
To improve this problem, Bridgestone introduced a new RFT tyre with sidewall texture similar to ordinary tyres, thereby enhancing the comfort of the tyre.
High replacement costs; and limited replacement choices.
If the material that penetrated the RFT tyres is not removed, continuous driving will result in the hole getting deeper. Once the hole reaches a depth of more than 5mm, there is no way to remedy them.
While the RFT is not so popular in Malaysia, increased advances in technology and maintenance of tyres translate to lower prices for them. Do not be surprised by the eventual rise in popularity of RFT that could one day put the history of roadside punctures to bed.
Run Flat Tyre abbreviations:
RFT: Run flat tyre
ZP: Zero pressure
EMT: Extended mobility technology
ROF: Run on flat
DSST: Dunlop self supporting technology
SSR: Self supporting runflat

Buying runflats in Malaysia will really bleed you.
Just replaced my front runflats for RM1100 each. These are 195-55-16 Goodyear Excellence tires. Sigh. It's selling only £100 per piece in the UK (checked from the internet). I should really have imported them

i concur..tires in m'sia are freakin' expensive..just come down to s'pore for tire changes..it's lot cheaper even after conversion rate...plus u get to shop here..hahaha..
