TKC's not road legal?

OK, Howard, reference the regulations. Tell us how to find them.

Perhaps, however, you can't. Perhaps you're just shooting from the lip. A hapless bullsh!tter, perhaps.

Bolloxs. I found that on a site somewhere. Can't be arsed to find it again. If you lot want to risk your life that's your problem. Go do it.

Another reasoned argument from the "I hate all things BMW" person. :bow :bow :bow
 
Anyone had sight of the "certificate of conformity" for the GS12?
Just got this from VOSA :-

Hello Howard,

Your enquiry has been passed to me hopefully I can be of some help.

BMW, as you rightly point out, claim the top speed of the R1200GS Adventure as "over 200km/h" (approx 124mph).

The tyre sizes quoted for the bike on the BMW website are: front -
110/80R19 and rear - 150/70R17. The R in both tyre size designations indicates radial construction.

On the Continental tyres website the TCK80 tyres are claimed to be original fitment for the GS, but the TCK80s are Bias belt construction so their size designation is 110/80B19 59Q and 150/70B17 69Q. These tyres are Q rated for speed which is up to 160km/h (approx 99mph)

The Continental radial tyre for adventure bikes in the above sizes are the Escape these have a speed rating of V which means suitable up to 240 km/h (approx 149 mph).

I can only suggest that you confirm, with BMW, that the tyres fitted to the machine you mention (GS1200A) are those fitted when the model was type approved. The certificate of conformity should include both the design maximum speed and the tyres fitted when approved.

I hope this information is of some use to you.

Best regards

Assuming they are the same size, just ask for 'Tyres for a Triumph Tiger, the same as the ones fitted to Howard Millicrap's bike, please'.
They'll last a lot longer than any BMW type tyre, and obviously be completely guaranteed against any chance of puncturing, plus less than half the price of BMW tyres.

So, while you can't be bothered to do a google search, you are prepared to go to much more significant effort and write to VOSA and enquire about a bike that, let's face it, you're never going to buy (and which wasn't, actually, the one at issue in this thread's first post)? :nenau The fact that you did that tells so much about you! :thumb

I did bother my @rse to do a bit of searching and found the following:

The Regulations that apply are The Road Vehicles (Construction and Use) Regulations 1986.

Searching on them gives the following results:

From http://www.police-law.co.uk/law/policelaw.nsf/0/158d1b65e849d5d780256baa005964b0?OpenDocument
The tyres 'shall be suitable having regard to the use to which the vehicle ... is being put ...'
and
'not a temporary use spare type (for use only if normal tyre fails and used at a lower speed)...'

About the 'best' I could find without getting a full copy of the regulations (which I couldn't find on the web) is from
http://www.etyres.co.uk/uk-tyre-law

Regulation 24 of the above regulations (the same regulations, Howard, not 'different' ones :rolleyes: ) says how temporary spares can be fitted. Later on the page it says that temporary tyres can be used up to 50mph. This establishes a precedent; if temps are OK to 50mph (as stated on the tyre and wheel), why aren't Q-rated safe and legal when they can go much faster - irrespective of the vehicle's top speed?

This view would seem to be reinforced by other comments on that site saying, 'All tyres must have a service description (i.e. load and speed index). If the vehicle was to operate outside the service description indicated on the sidewall e.g. at a higher speed or overloaded then the tyres would be deemed to be unsuitable for the use, and a prosecution would follow.' And so it should.

So my points, unless you're still not getting it, are that it's not very impressive to state knowledge of regulations that confirm your point of view then storm off in a hissy fit when challenged. :nono

Nor is it particularly helpful to assert that a situation is 'totally unsafe' when it quite obviously from a practical point of view and almost certainly from a legal point of view, is deemed safe. I remind you that, in the country in which those regulations apply, it isn't legal to exceed 70mph so the Q-rated tyres are never going to be challenged (legally). If you want to bring up the IoM, fine but it tends to prove my point rather than refute it because even there you can be had for exceeding the tyres' ratings when you're not exceeding the local speed limit. The system works! :)

But, all the while, at the heart of the argument is the truism that Cheesy Mike said in his post a while back: 'I also fail to see how a 98mph rated tyre could be considered unsafe on a bike that can only be used at a legal speed of 70mph in the UK. Anyone who rides at a consistent speed greater than 98mph long enough for their tyres to delaminate or blow has, IMHO, much bigger problems to face than how their tyres are going to perform.' :clap
