An experienced bicyclist's motto is (or should be) "never walk home". Flat tires, broken chains and bent frames are just some of the mechanical problems that a rider can encounter when they are out for a ride. Experienced riders learn quickly that there are not too many mechanical problems that can stop a resourceful and determined individual.
A cyclist should always be prepared to fix the most common breakdown, a flat tire. A simple tire repair kit should include a tube, a couple of tire levers to aid in removing the tire, a patch kit and a pump. The cyclist should also be prepared to repair a tire cut which leaves the tube exposed to the ground. This repair can be made by cutting a 1x1-inch piece of old tube or even by bringing along a dollar bill which can cover the cut temporarily during the ride home.
So what happens if the cyclist flats and does not have a patch kit or an extra tube? Each cyclist should carry an air pump so the tire can be periodically inflated and the ride continued. A slow leak can be annoying but you can add air each time the tube softens. Fast leaks will have to be sealed. A small piece of duct tape can be used as a temporary patch. The tube will still leak but you should be able to use the "pump and ride" approach that is used with any slow leak.
If you do not have the tape to repair a fast leak you can locate the hole and place this area outside the tire bead when remounting the tire. This exposes the tube to the ground but when the tube is pumped up the tire seals the tube. The tube will bulge outside the tire but it should not blow off the rim unless it is overinflated.
Another technique is to fold the tube back on itself inside the tire so the hole is covered. When the rider pumps up the tire the overlapping tube slows the leak.
So what happens if the rider gets a flat, and has no extra tube and most importantly does not have a pump to inflate the tube? This is when riders must be resourceful and creative. The rider can stuff grass and weeds inside the tire. The more grass the better, as that will help keep the rim from making rough contact with the ground.
In the event the bicycle tire gets ruptured and will not stay on the rim then the cyclist will be left with no choice but to ride on the rim. This makes for a tricky ride but it is possible and should not damage the rim too severely. Rear flats on road bikes will likely cause the most rim damage. The rider should be able to get the bike home while riding slowly and staying off the seat as much as possible.
A cyclist always run the risks of mechanical problems like flats. These problems can be corrected with a little ingenuity and resourcefulness, even when they find the tools available lacking for the task at hand.
Car Tyre Puncture Repair
The basic legal requirements for car tyres are:
a) Tread Depth must be a minimum of 1.6mm. This applies to the entire circumference of the tyre. A bald patch on a tyre, where the tread depth is below the minimum requirement, is against the law. Check a tyre after a skid or emergency braking as this is when bald patches can occur.
b) Tyres must be inflated to the correct pressure. Consult the vehicle manufacturer's handbook to find the recommended pressure. Not only is this a legal requirement, it improves the vehicle's handling and reduces fuel consumption.
c) All four car tyres must be compatible and in good condition. If a car tyre needs replacing it will need to be in the same condition as the others otherwise all four will need to be changed.
Factors that can affect the rate of car tyre wear include:
1. Make of Car Tyres
Every car tyre is designed differently to meet specific criteria. Long life tyres are made from a harder rubber compound. This can increase the noise when driving. A softer tyre compound will be quieter but will wear out faster. A car tyre specialist such as Merityre can offer advice on the different types of car tyre.
2. Position of Car Tyre
Front tyres wear out faster than back tyres, especially if the car is front wheel drive. The extra wear is caused by the movement through steering. On a four wheel drive vehicle the front car tyres should exceed 20,000 miles. This is half the expected life of the back tyres.
3. Weight of Vehicle
The heavier the vehicle the faster the car tyres wear.
4. Tyre Pressure
A car tyre that is inflated below its recommended pressure will wear faster because of its higher operating temperature and the extra flexing of the rubber. Over inflation can also increase wear due to the decreased size of the contact area between the tyre and the road.
5. Speed
Driving at high speeds increases the car tyre temperature and accelerates the wear.
6. Car Tyre Alignment
Incorrect alignment of car tyres causes uneven and increased wear.
7. Driving Style
Aggressive cornering, accelerating and braking excessively are all causes of car tyre wear.
One factor that is unavoidable is time. Tyres deteriorate naturally over time due to the effects of the weather. Car tyres on vehicles kept outside will degrade faster than those kept in a garage. Cracking due to sunlight exposure usually becomes evident on car tyres that are five years or older. When this happens, as with any signs of wear, replace the car tyre immediately.
