Floods have featured heavily in the news media lately. We've just experienced the wettest summer in UK history, and the consequent flooding has affected a number of cars. In some instances the results have included fatalities. Your car tyres may provide as much grip as you need – until your car starts to float. Yet the tyres won't stop a car sinking, or being swept away. Here's how to deal with floodwater.
There you are, driving along, minding your own business. It's pouring with rain but you're perfectly confident about your car tyres' abilities on wet tarmac. Then it happens, you're faced with glossy sheen of floodwater in your path. Your thoughts begin to race. 'Should I keep going, or turn round?'; 'Will I get stuck?'; 'How deep is it?'
Depth is the very first thing to consider in such a situation. In most instances, a car can handle floodwater as deep as its wheel rims – the car tyres will be submerged but they'll cope. The snag is; how do you gauge the depth of the water?
There is no simple answer to this question. You may have local knowledge to tell you what to expect in a given location. You may have a good view of the white line, or you may have just seen another car successfully wading through the water. There are, however, warnings to consider. For example, you can bet your car tyres that a flood stretching away out of sight, such as around a blind bend, is liable to get deeper. Similarly, your seeing a big 4x4 happily paddling doesn't mean your saloon car will manage.
Apart from your car tyres' role, the major element to consider is your engine. All engines compress the fuel and air mixture that enters their cylinders. A petrol engine may squash the mixture by a factor of fourteen, while a Diesel engine might compress the mixture to twenty-five times atmospheric pressure. Here's the rub: you can compress air, you can compress vapourised fuel but you cannot – repeat cannot – compress water. A surprisingly small drink of floodwater will instantly stop whichever pistons encounter it. However, the connecting rods will still be pushed upwards by the crankshaft…but not for long. Broken or bent conrod(s) – for which read 'scrap the engine' are the inevitable result. This is exacerbated by many modern cars having a low-mounted air intake. Cool air drawn form low down equals improved combustion. Water drawn into the air intake equals a dead stop.
What, then, is in our line of defence before we try to dip our car tyres into floodwater? Local news, via the TV, radio or Internet, are helpful sources, provided you pay attention to them. It's also a great idea to have a fully charged, functional mobile phone with you, just in case. Remember that, if you encounter a flood, asking around – especially if the police are present – could save your life, let alone your car.
Now for the worst-case scenario. You arrive at flood and have to decide on how to tackle it. Stop and take a look, getting out of your car unless you're 100% sure of the water's depth. Is the white line, or the underwater tarmac surface visible? If so, remember you can go to about the depth of your car tyres' sidewalls in most cars. Is the water still? If it's rushing, forget it – unless you fancy being on the news. Moreover, if someone starts beeping at you to hurry, invite him/her to go first. You'll know what to do if this car suffers a grinding halt.
Assuming you plan to go for it, put your trust in your car tyres and go slowly forward. Use a low gear, so that the increased engine revolutions will allow the exhaust gases to keep the water at bay. Go slowly, so as to not create a big bow wave – which might just drown your engine. And remember to stick to the crown of the road, where the water will be shallowest.
Finally, though your car tyres will dry off after a few revolutions, your brakes will stay wet. Lightly touch the brake pedal until you feel the brakes bite again.

Life Lessons. How To Maximise Car Tyre Life
Maximizing your car tyres' useful life is as much about being both safe and legal as it is about saving money in the long run. Your car tyres may not receive too much of your attention but a combination of forethought and maintenance will help you achieve the very best results for your car tyres.
Buy the right tyres
Car tyre choice is a matter of making an educated selection. So-called 'long-life' tyres may perform as advertised but can have downsides. They are liable to be noisier in use than 'normal' tyres, whilst also being less grippy. Similarly, 'normal' tyres could save you a few pounds but could let a higher performance car down grip-wise. The solution? Trust your tyre fitter.
Make sure your wheels are properly aligned
Given that wheels running out of alignment spell an early demise for car tyres, it's worth having a wheel alignment check at tyre replacement time. Significant misalignment will show in odd wear patterns on the tyre treads, and can make the steering feel odd.
If you've encountered a big pothole, road debris, or have had an argument with a kerb, get the alignment checked as a matter of course.
Use the right pressure
You can usually find this out from a sticker on your car's doorpost, or from your user manual. Too little tyre pressure can cause fuel-wasting drag, excessive tyre flexing and tyre failure through overheating. Too much air in your tyres can lead to premature wear and unreliable handling.
Drive with sympathy
…,for your car tyres, that is. Consistently taking corners at 9/10th of your car's (or your) abilities shortens tyre life. The same goes for aggressive accelerating and braking. Movie stunt men don't have to pay for their car tyres!
Give your tyres a break
Following on from the previous tip, this kind of mechanical sympathy specifically concerns physical damage to your car tyres. We have, for our pains, got to put up with speed bumps and speed pads on our highways. We don't, however, have to let them damage our car's wheels and tyres.
The way to tackle these devices is to treat them as what they are – hazardous to your car tyres. Always cross them slowly. If you come across the kind of speed restrictor where there's one speed pad per carriageway, never straddle them. Instead, let the wheels on one side of your car traverse them. Also, try to avoid touching a kerb, far less mounting one.
Driving like this will protect your car tyres, as well as greatly reducing the chances of expensive and/or dangerous damage to wheels.
These are proven practices that will prolong the life of your car tyres. They can also help save wear and tear on your car's wheels, suspension and steering. Don't be misled by knowing that car tyres are very tough indeed. They are tough but they aren't invincible. Pay attention to the above and stay safe, and you will save money by not having to replace your tyres before their useful life ends.
