Winter tyres VS Summer tyres
We have compared compared to the Arctic Circle to find out exactly how much safer winter tyres are in cold conditions compared to summer tires which is what most of us Brits have fitted to our cars all year round regardless of how bad the weather is to do this we’ll be conducting a number of tests to see how a car performs on each type of tire in the snow for consistency we’re using the same brand of rubber and the exact same make and model of car the red sale outlay on is on the summer tyres or the white one winter tyres.
So what’s the difference compared to summer tyres, winter tyres are made from rubber which stay soft at lower temperatures or their more complex tread pattern helps grip onto snow right then our first test is braking from 30 miles an hour where our drivers reached this cone they’ll do a full ABS emergency stuff and we’ll measure how long it takes for them to come to a complete halt okay then here we go the white cast stops easily while the red one carries on for ages the car with winter tyres on took 27 metres to stop with the one we simmer tires 85 metres that’s more than three times the distance and if you think that scary consider this at the point the white car had stopped the red one was still doing 25 miles an hour.
The next test is about traction to find out how easy it is to get moving on each set of tires so we’re going to have a drag race with a difference in time how long it takes each car to get up to 30 miles an hour ready go the red car is left floundering while the white one pulls away cleanly in fact thanks to its winter tires it manages to get to 30 and stop again while the red car is still way off its target speed a final test is about making an emergency maneuver when our cars reach this gate the drivers will suddenly apply half a turn of LOC as if something stepped out to the road in front of them and they’re trying to avoid it first up winter tires the white car responds to the sudden steering input almost as though it’s on a dry road now for the summer tires this time the driver turns the wheel but little happens in fact the car pretty much plows straight on well then I think the evidence is pretty conclusive isn’t it?
If you want to make yourself as safe as possible in snowy conditions you need to get yourself a set of these winter tires because quite frankly these summer tires aren’t up to the job however experts reckon we could benefit from winter tires even when it isn’t snowing as they improve braking in the wet at temperatures of seven Celsius or below which it is in Britain between October and March.
To test this theory out we’ve come to Continentals proving ground in Germany with a climate is pretty similar to that in the UK with us is David qual B is the chairman of the RAC foundation wants to see for himself where the British drivers should consider running winter tires for half the year so he’s going to conduct an experiment for us we’re gonna see how long it takes our car to break from 50 miles an hour in the wet on first the winter tires and then the summer tires with a temperature of the air and track below seven degrees we’re good to go so let’s start with the winter tyres once up to speed David is going to hit the brakes when he reaches the cones on winter tires the car stops in 35.5 meters which is impressive for what happens when we change the cart on to summer tires let’s find out this time the car took forty two point five meters to stop that’s an increase of seven meters which is more than a cars length in fact at the point the car is stopped on winter tires on summer tires it was still doing 20 miles an hour but what does the difference feel like from behind the wheel the summer tire felt like it normally does when you’re having to do an emergency brake it kind of judders to a halt a bit but you get get there and it’s fine.
The real difference with the winter tire which really struck me was not only that you stopped in quite a significantly shorter distance but it feels much more stable so then we’ve seen that winter tires not only improve safety in the snow but also when it’s wet and cold as a result we’d all benefit from having them fitted to our cars for about half the year.
