new NCT criteria - oem tyres

xt40

i know there is already another thread but i thought this was so ridiculous to be deserving of its own thread. i heard on the radio (matt cooper i think) that they were talking about making it compulsary to fit the original tyres as specified at time of manufacture. there was some bulls**it about cars being designed to go and stop optimally with a specific tyre. :mad:

I didnt hear that one myself, but the idea is crazy.
No doubt an idea being floated to prevent people purchasing tyre bargains.

Sounds like bull to me. Are they taking about exactly the same tyre, or perhaps they're talking about having the correctly sized wheel for the vehicle? Because having the exact same tyre is not only a ridiculous suggestion (who goes to find out exactly what tyre should be on their car?) but is also one which is likely to reduce safety as tyre technology may have come on somewhat since the car was manufactured.

Correct wheel size makes more sense. There are a lot of instances of people morons fitting 17" and 19" wheels to vehicles which are completely incapable of handling them. It increases the risk of catastrophic failure which in turn makes the vehicle more dangerous.

I know a few of the new "Low CO2" versions of cars come with special wheel / tyre combo's to bring the CO2 under certain levels. If replaced with different tyres or wheels the CO2 emissions go up above those stated, which in some cases could move a car from one VRT band to the next.

If you were to spec Alloy wheels on a Golf MKVI 2.0Tdi 110bhp Comfortline from the factory, it would move it in to the next VRT bracket - all Alloys will be dealer fit to get around this.

Other than that, it's just pure stinking bullsh1t :mad:

Don't believe everything you hear on the radio. Read the actual proposal here ...

http://www.rsa.ie/publication/publication/upload/NCT%20Consultation%20Paper%202009%20FINAL%20ROB200209.pdf

As far as I can see there's only a new requirement that tyres are marked with an E mark showing that they come up to EU requirements.

No mention of that in the proposals, but it makes sense.

In Germany your car papers (Fahrzeugschein) have details in them as to what size(s) of wheels and tyres are allowed on your car, and if you're stopped and found with the wrong ones you can get into trouble.

noway .. i wonder how long it will take to catch on here

They did say on the show its from a consultation document, so they just want points in it to be debated. How would they implement that when manufacturers can change the specs themselves? Renault changed all their Laguna II wheels from 17 to 16 (Other way round?) inch wheels because they were bursting on contact with kerbs. So if you hadn't changed yours, you would be failed?

Read the actual document in the link I provided above. No mention of what's being discussed here, only that there must be an E or e mark on the tyres.

The OP's original post is concerning what they were discussing on Matt Cooper last night, which is what I am referring to. You are pointing out tyre thread, not the tyre design. They quite clearly discussed this last night at length, with the guy in favour saying certain manufacturers had tyre companies manufacture tyres to go on certain cars, and (I think) he said something about cheaper Chinese imports not being suitable, which probably fits in with the "E" mark.

... and I was pointing out that in this very consultation document, to which I even helpfully offered an online link, there is no mention of this whatsoever. Did you bother to read it? "They" can discuss whatever "they" like, but if it's founded on inaccurate information then why pay any heed to it?

Its a bit long to read all of it now so I found the tyre parts, plus I didn't have it when they were discussing it last night. I may be wrong but it seemed like a spokesperson from the RSA that was talking about it, and it is their document, so it seemed legit.
If it annoys you so much, ring Matt Cooper tonight and point out the error in it. I was just trying to point out that it wasn't in fact a "done deal"
