Papa Serf Posted December 3, 2010 Share Posted December 3, 2010 Need to be really carefully with having better grip on the front wheels, the rear wheels lock and skid and quickly overtake the front wheels. Especially when trying to stop going down a hill. Link to comment Share on other sites More sharing options...
Pent Up Posted December 3, 2010 Share Posted December 3, 2010 Yep agreed 3 years sounds a bit little. Driving wheels sort of makes sense as my socks just go on them too and it works fine. Only issue would be emergency brake - back end would just spin off of its own accord !! I done several emergency stops, in a straight line, to test it and had no problems. The only time I seem to lose the back end is when accelerating into corners faster than I need or should be. I'll try some more tests when I get a chance Becuase the tyres are inpregnated with a silica compound to keep them flexible in the extreme cold their length of life is reduce compared to normal tyres. I'm just relaying info I've got back from friends in Belgium, Germany & Czech Republic based on actual experience regardless of whether they kept on steel rims or taken off in the summer. One other thing to note, even though you are increasing your safety by fitting winter tyres, your premiums could go up as its classed as a modification. http://www.honestjohn.co.uk/news/tax-insurance-and-warranties/2010-12/winter-tyres Its just another excuse by the insurance companies (part of the financial sector) to make more money. That does make sense. I'll let you know how they are doing in December 2013! Link to comment Share on other sites More sharing options...

Now I understand. So only 3 winters for a set. However you will also save on less wear and tear on your normal tires. Seems a decent trade off to me. And of course you can drive places most other people will not be able to in heavy snow. As for the insurance I have also read a bit about that. A few I hav read just called up to explain and it was fine. Pent up - please get someone to film your planned experiments. Link to comment Share on other sites More sharing options...

northwestsmith2 Posted December 3, 2010 Share Posted December 3, 2010 Tried a Mountain bike with proper tyres and even on ice where I would fall over instantly as a pedestrian it has no problems whatsoever. Really it was astonishing the level of grip on ice the capabiilty in deep snow was like riding on a dry tarmac road and even compacted refrozen slush on pavements wasn't a problem. The best part is getting past queues of traffic and into town but it makes my autosocks a bit pointless Link to comment Share on other sites More sharing options...
Harry Monk Posted December 3, 2010 Share Posted December 3, 2010 Just a quick tip, if you have a RWD car with a handbrake that works on the rear axle, you can lock your differential by pulling progressively on the handbrake. When the braking resistance exceeds the resistance of the driven wheel with the least grip, the axle will lock up and both wheels will provide traction, rather than just the one with the least grip.

Good tip, I was thinking along the same lines the other day but I've got a punto so it doesn't help me. Link to comment Share on other sites More sharing options...
sleepwello'nights Posted December 3, 2010 Share Posted December 3, 2010 You mean like this? I did the same sort of training courtesy of a young driving scheme run by Herts Police & Herts County Council when I was a boy. Great fun and worth doing as it shows and teachs you lots of things. Yes I had a driving day including a skid pan session using that contraption. It was great fun. I remember before we started the instructor asked our group what we should do if we got into a front wheel skid or a rear wheel skid. So the usual responses were steer into it steer out of it., or whatever. The instructor dismissed all our comments, he told us when you get into a skid you won't have time to think, oh it's a front wheel skid so I'll steer into it , or the back ends gone so I'll give it some opposite lock, or whatever. We were told drop the clutch to cut the power, look where you want to go and relax. So strange it just worked, you always ended up where you looked.

Just like riding a motorbike, if you look at where you don't want to go or look at what you don't want to hit you will hit it. Link to comment Share on other sites More sharing options...

Fell off a few times so gave up. I do have tyres that are pretty good on the tarmac though so you maybe have chunky ones ? I have these. Link to comment Share on other sites More sharing options...

erranta Posted December 4, 2010 Share Posted December 4, 2010 Yup that's the kind of thing. This is an HPC heads-up! If you are going to buy any car snow aids/sledges for kids/snow shovels/related items - get them now before the UK sells out/extortion prices! Get a supply of anti-freeze/screen antifreeze in too and check your car antifreeze levels - should be 50-50! Link to comment Share on other sites More sharing options...

When the braking resistance exceeds the resistance of the driven wheel with the least grip, the axle will lock up and both wheels will provide traction, rather than just the one with the least grip. Interesting, would the same thing not apply to a front wheel drive car by applying the brake pedal? I think that is how some traction control systems work. You might have to be the "heal and toe" grandmaster. Or maybe not, if the clutch was fully up and one wheel was just spinning. Or if it was an automatic.

Not sure why they work but mine are Scott OZON 2.0 70a compound, pressure is about 40psi or lower. http://www.nyc-sport.cz/ Link to comment Share on other sites More sharing options...

Must be the compound I imagine. Although no chance of me biking up here today. Mental snow. Link to comment Share on other sites More sharing options...
