Run Flat Tyres!  As a full time wheelchair user getting out of my van to change a wheel in the event of a puncture or flat tyre isn't really an option for me!  I just cannot afford to get stranded in the middle of nowhere waiting to see if a repair guy can get to me.

Fortunately for us they now make tyres that you can drive on even when you do get a puncture.   That's right you can do 100 miles or so at 50 mph all the way home safely!

I just ordered a set of these Dunlop 245/50 18 Sport Maxx GT ROF tyres. (Tires if you happen to be an American!) Click image for a bigger view.  They look exactly the same as the Dunlop ordinary tyres do. 

 If you are a wheelchair user and you drive a car or a bike consider buying a set of these now!  Before it happens!  No more wheel changes needed leaving you stranded and waiting for rescue...  Call  your friendly tyre shop today!

For e.g. the cheap Korean "Ecsta" tyres fitted to my van at the moment come in exactly the same style, tread pattern, and sizes both in normal tubeless and these "Run Flat" versions.

The run flat ones are around £30 pounds more expensive than the normal ones are. A small price to pay for peace of mind and ability to get home easily! 

Technically you should also fit an aftermarket tyre pressure monitor as well and these are pretty cheap. Ranging from fancy valve caps to electronic systems that display pressures inside the vehicle.  Otherwise you may not notice you actually have a puncture. But if you are an alert driver you can feel it as a SLIGHTLY soggy tyre... And you can see it as you walk (wheel) around the vehicle too. Looks like it needs some air!  So as long as you understand this you could probably not worry about the pressure monitors...  Unless there are legal requirements in your country that is.

Downsides: They cost more, they are slightly heavier, they give a slightly harsher ride. Its not easy to tell though so don't let this put you off.  All small prices to pay if you are a wheelchair user I think...

Positives: Punctures are no longer a worry, essential practicality and no need to carry a spare freeing up some space in our modified cars and vans! . And its a good excuse to fit those bigger fancy alloy wheels you wanted anyway!  And since you now need to carry no spare wheel you can have a LPG conversion where the donut shaped tank replaces the original spare wheel. Which is my next step since LPG is far less than half the price of Petrol or Diesel.
