Mobile tyre fitting

mobile tyre fittingis here to stay because there are so many cars are on the road without a spare wheel. So whats going on?? Car manufacturers fit runflat tyres, spacesavers or worse still inflator cans as a "get you home" option. All in an attempt to save a few kilos in weight to improve economy figures.



Runflat tyres are extremely difficult to fit but all of our mobile fitting units are equipped to fit them. They are more expensive than standard tyres and once you puncture them they are designed to drive for 50 mile or so. After you have driven on them they must then be disposed of. You cannot puncture repair them.



Space saver wheels are limited to 50mph and only have 3mm of tread. A new standard tyre is typically 8mm of tread. They are also limited to 50mph.



The newest technology is the continental seal tyre. This tyre has an additional belt inside the tyre which is effectively a "soft latex or bitumen" type compound. If a nail pierces the tread you simply pull it out and the bitumen seals the hole. However it does not work on cuts in the tyre.



A few years ago a product called Ultraseal was marketed which was extremely good. You put a measured amount in the tyre when it was fitted. Effectively if you have a puncture the compound leaks through the hole and permanently seals it. The ministry of defence used this product and tested it on bullet holes!! The repair is permanent enough. It was ideal for caravan tyres ie a flat tyre on on a box you are towing on a motorway can be frightening. Ultraseal was causing problems on low profile high speed tyres because of centrifugal forces but these did not affect caravans which are limited to 60mph.



Another product in the market is TYRON bands. These are metal bands inserted into the tyre to stop it totally deflating and in some respects allowing you to carry on driving, Similar to runflat tyres technology. However they are time consuming to fit and the tyre fitters quickly moved away from these.



All of the above technologies have flaws and at some point you are going to be stranded on the side of the road without a spare tyre. Just call the local mobile tyre fitting to come and rescue you.
