Logiclee,

The Winter Tyre Warning feature needs set by the Driver or the Tyre Fitter / Dealership etc.

 

So that is where we came in with Sittingbull's post yesterday.  Post#117

 

*People need to read the Owners Manual or maybe BRISKODA,

they will probably be equally as il-informed.*

 

You need to know the Feature is there

choose a speed to set it at.

And even with Tyres on with a 130 mph Speed Rating and the setting at 100 mph, 

someone doing 90 mph in your car with M+S Tyres or full Snows on has no idea still what they are driving on without having 

looked around the car.

 

An Obvious Sticker 'warning' is a very Good Idea,

And you can set your Winter Tyre Speed Warning Low, and also your 'Speed' / possible Lose your licence warning as well.

Now you are being silly for the sake of it are you not.

The point is about what the tyres might be asked to do when it is not winter conditions,

ie on all the times when the M+S usage is not relevant, dry roads summer roads, 

those unlimited speed roads,  'A Warning of the Tyres on the Car, or that 'The Sticker is fitted but you better still 

look and see, because the Semi Slick Track Tyres might still be on the car'.

Is that not what all this theory is about in this thread.

 

Well I only have Winters on one car ie the little Chevy which only does a ton with the wind behind it and it make the most sense to have on though maybe the Fabia HTP as well.  The others have All Seasons though I am struggling to get one for the Jaaag and am thinking about changing the rims.  V rated All seasons are quite rare except in premium brands at about £100 a tyre, ouch.

 

So would actually not use Winters unless it was snow for weeks on end like the Winter of 62/63 ie between Xmas and Easter.  Probably not likely in the UK but then you never know with record El Nino this year.   

 

All Season are the better option for most of the UK in my opinion, perhaps all year round like some emergency services do.  Find none of my All Seasons noisy, wet grip is B rated or better, happy days and motoring.

It amazes me how little some people know about the systems on their vehicles but as an Electrical Engineer involved with tech all day and a self confessed gadget freak I'm at the other end of the spectrum.

 

I set my electronic limit at the tyres limit. The legislation thinks if you are doing 90 on winters that have a speed rating of 130mph then you are perfectly safe, why would you need a warning.

LOL,

Why do you need a warning for anything, check your vehicle before driving, know the law, know what the vehicles does,

know the national speed limits, know your tyres, know your pressures, and know you are insured.

Simples.

& Read the Owners Manual and all Manufacturers Stickers, especially in Vehicles.

 

If your local Friendly Trained Technician or work colleague decides to Speed Test your vehicle and see if that Misfire is there at 6,000rpm

you might want to let them know before really going for it the car is not on the OME Tyre Fitment.

* They can See / hear the Winter Tyre Warning when first Exceeding the NSL, then decide from then how much they want to exceed it with the tyres that it says the car has on..*

Good as a bluff, makes them think.

 

PS

Because Tyres are OK for a Speed / Load Rating, 

that does not mean that Summer Tyres with a high Speed Rating are perfectly OK at 150 mph in the Cold or Wet weather,

they are given a speed rating for what the tyres are capable of up to a certain speed and usage not the driver.

There is no accounting for the stupid.

We do not have an accurate way of measuring speed on a standard specification car.

 

Analogue instruments with a rough average of 5% over-read, non-linear.

 

We have to go out and buy an accurate device ie Satnav as an add on.

 

Now we have a Police Commissioner ie Beds, saying he is going to do us at NSL +1 mph rather than 10% plus 2,3,4 mph, not cricket. 

I swapped mine onto the Polo yesterday. 

In the process discovered a sizeable flake of nearside rear disc was falling off, so I'll have to bring forward replacing them.  Maybe a job for tomorrow, burning some unused annual leave by having the next 3 Mondays off.

lol-lol,

travelling the A9 Average Speed cameras regularly on slightly oversize OME Tyres i have my Cruise control in one car at 72 MPH 

and the other car at 73mph,  and by the GPS i am at 70 mph.

I have checked with a V-Box and the indicated by the speedo 72 & the 73 are actually 70 mph.

(Edit while set at 72mph on CC and the Speedo Showing 72 mph, the Maxidot Average Speed display for that journey 

might well show it as 70mph.)

You can never have an accurate wheel driven speedo.

 

The difference between new tyres and worn tyres can be over 12mm diameter change on your tyres. And then there's rolling circumference changes due to actual tyre pressure.

 

Even companies differ with tyres of the same size.

 

Swapping from Continental Conti Sports to Goodyear F1's made my speedo overread by an extra 2mph at 70mph. When measuring the F1's were 10mm wider and lower profile than the Conti's even though they were both 235/45's

When you change Tyre Sizes on some VW Vehicles you might set the Mileometer at the start of a trip,

and the Maxidot Trip Set, and after a few hundred miles the reading are not matching, maybe only a few tenths of a mile difference, but there can be a difference.

Indeed it is measuring a related item and not the actual across ground.  Amazes me, and anyone who things about it how complex the calculation for satnav when you are using 3 plus satellites, changes in elevation, the Earth is nowhere near spherical, incredible. 

 

I follow the SATNAV for better or worse and assume accuracy of around 1% but rounded up so tend to set at 1 mph below displayed speed unless reckon that zone is on the 10%+2 setting but now worried that police are looking to go for actuals plus only 1 mph tolerence!

Police Scotland have told the Public what they are doing and at what you can expect to be stopped and given your first Official Warning,

they got the go ahead to do it from the Scottish Government

& Some Police Forces in England & Wales have said what they intend doing.

 

You know how to adhere to the Speed Limit that applies to you, and if you are in doubt, best stick just below.

There's a 1.8% difference between my summers and winters on the Passat. Always forget to reprogram the TPMS and always get an alarm on the first run out.

Hopefully you are less forgetful when doing your Electrical Engineering duties you mentioned a few posts back.   Winky thing.

Too much paper work involved if i do.

 

Twice a year, I ought to remember. I need to write up a procedure and have a tick sheet for winter tyre swap over.

5 degrees this morning......with all-season tyres (Michelin Cross-Climate) and starting from cold.....

 

 

3 miles trip

48MPG

 

 

On return trip

 

 

 

     

I think there's something wrong with your instruments wayne the one on the left says power !

oh. cheers Chris.

 

I cant see the Sig on mobile version

 

It looks very funky though haha

My apologies then...LOL

Funky it aint!! ...But Wayne is happy, so that's what counts

its abit futuristic. i like it. looks good.

Having winter tyres with a lower speed rating than summer tyres doesn't necessarily make them unsuitable for use on the vehicle though.

The tyre pressure sticker on my Subaru says:

 

Summer tyres: 225/55R18 98V

Winter tyres: 225/60R17 99H

 

This is also repeated in the handbook.

 

Simples. No ambiguity. No insurance issues.

My All Seasons are H rated.

Best set the HTP 70bhp speed warning to 130mph then.. Or it wont be strictly legal?

LOL. Thatll be going off regular...

I thought so too - I mean, the word POWER and HYBRID don't exactly go together (unless u got a Tesla!)

Just fitting an aftermarket Transportation rear seat - got it from a Star Trek convention-cum-jumble-sale ....
