Feck that was scary

[Shadwell]

Bloody hell, i was crapping my pants driving up the A1 in a landrover in 4x4 diff lock on today, never mind on my bike.

Incidentally i bought a brand new 8 two weeks yesteray, and its bee sat in my garage since! i have not had the balls to even take it up the street!!

I want it to melt, now (the snow not the bike)

 

[Ogmios]

yes.
interesting.
Mrs Og used to navigate(long before sat nav) for mountain rescue, so though at the time, not a driver she had to attend the driving courses.
they took a drive over a frozen lake - normal tyre pressure and lowered.
on normal pressure the car 'glided' regardless of steering input - trying to get whatever was the heaviest point in the car facing the direction of travel.
lowered pressure = greater control. simples.

however,
i can see how an Ice Racer - highly skilled at making rapid progress could get better grip and therefore speed out of a deep biting skinny tyre/stud combination.
But,
i'd be on me ear in minutes!
personally,
the lower pressure for cautious progress would be what i'd try first.*

from the start of this cold snap til now i've ridden the GS (the Guzzi sits like an deformed snowbeast out the back ) whenever needed. (i dont possess a car).
but tonight my commute (only 3 miles) took an hour and a half between sheet ice, gridlock (main reason).
feckit - first time in 29 years i'm walking to work tomorrow.

*as for what i'd try last....
chicken wire laced to the rims as 'snow chains'.

"interesting"

I know people might think one thing or the other about you going out on the GS today, but I do feel sorry for you and the bike. It's not nice when you damage something under any circumstances.

Sorry, can't seem to find an appropriate smiley.

There are loads

It's all about gaining traction and control we're not talking racing here we are talking slow speed manouvering

Traction and Less slippage is the way to maintain forward motion and control

If you have a hard tyre and normal pressures it will not deform to the road's bumps and lumps or even broken snow or ice ridges below the top layer and you won't get traction

I live about a mile from the main road where it is salted but we have a dozen bends and steep inclines to negotiate

The only time I had trouble I did what I said and let the rear tyres on My Merc 190D down till they formed sort of a "squishy cushion layer" which gained me some traction and I got out and back that way (Blowing tyres up at first garage again) and dropping them just before playing on the snow on the way home

I'm not recommending it as the be all and end all

All I'm saying is if conditions are bad even on ice, the deforming tyre will produce traction that the fully inflated won't and will aid you getting home!

Just to prove how you can get cought out, I went out for a couple of pints at 5.30pm. Got home 5 minutes ago and I feel very dizzy, wtf is going on

Txtd to make sure you got home..no response..thankfully you did.

I'm just in..had to walk the last 2 miles

 

[Borderraider]

In sand, you ceratinly let the tyres of your 4x4 down to whatever they will take without slipping on the rims, granted.

Watch a sand racer though.....what do they have? Narrow tyres.

I've seen it myself, in the Sahara, on the plymouth Dakar challenge in '05...the only two vehicles that didnt get stuck in deep sand were a VW beetle (old stylee) and 2CV, bith with very narrow tyres.

Watching cars race on snow, again, it's struck me that their tyres are very narrow.....

I'm sure there's a very complicated equation that will show it's a complicated balance between tread pattern/depth, pressure and coeffecient of drag of the surface, but on fresh snow, on a bike, my instinct would NOT to let pressures down.



PS this could be interesting

Examples you give are for 4x4's & Cars..If you were Trail riding in mud/snow would you run road pressures of say 36-42 or drop them to 12-16?
I know what I did.

Ok, you have me beat.....it's a low down trick to just chuck in these high-fallutin' technical terms ya know....."squishy cushion layer".....how can anyone compete with that sort of science

Okay how would you describe it without a photo???

 

[Deleted acc oony]

Some amount of shite lying around your yard ya messy twat get it cleaned up afore I phone the council

I'm just in..had to walk the last 2 miles

I'd passed out by then
Only fell over once trying to get up the hill. Leather soles, ice and 6" of snow on top made for the ministry of funny walks

reminds me of a girl i once went out with....

agree, and when you overtake parked cars,get to junctions , realise the surface changes, i try keeping to deep snow, iv made it to work every day, which is more than what most cars have,,,why the feck do people still try accelerating jus to see if its slippy????????
as he says, slow it down,,, couple of minutes dont matter, plus, you look a right tit when you on your ass blaming the snow,,,

Blah blah blah blah you should see how slow I was going. I'm a canny experienced rider thanks!

One heavy bike on ice ... going down! I only fell off at walking pace on the back streets where the ice and think snow was.

Found out ABS on ice doesn't work I still got put on my arse. Works on snow though, just ain't quick enough for the ice.

Bike has been away today to allow the Oddessy to go flat again.
