Taken from EVO and obviously relates to Europe....but how long before Aus follows suit... "New safety regulations spell the end for extreme road-legal rubber

By Roger Green23rd June 2009New legislation on tyre labelling and accompanying minimum standards to be introduced simultaneously in November 2012 will effectively end the production of road-legal trackday tyres. Tyres likely to be axed include the Dunlop Direzza, Toyo 888 (currently available on the Renaultsport Mégane R26.R), Michelin Pilot Sport Cup (Porsche GT3 and GT2) and Avon ACB10 (Caterham), along with a host of others.

The aim of the new regulations is to both raise all-round performance standards and to give buyers a greater understanding of the performance and environmental impact of each particular tyre before purchase. All road-legal tyres will have to display rating figures for rolling resistance (fuel efficiency), external noise and wet grip, and while the rating system and minimum levels have yet to be set, it is unlikely that track-biased tyres will be able to pass on all counts.

Tyre manufacturers are currently lobbying the European Parliament, but it will be very difficult for them to make a successful argument for tyres that allow drivers to corner faster in the dry but which offer a significantly lower level of performance the moment the surface becomes damp.

It is expected that trackday tyres will fall foul of the other parameters too, so their demise is something their manufacturers are already preparing for. James Bailey, Dunlop’s PR chief, believes it highly unlikely that trackday tyres will continue in their current form, although the company’s official position is that these regulations are positive as they will also remove poor performing cheap road tyres from the market. In its own braking tests the difference between the best and worst tyres fitted to a Mondeo stopping from 50mph on a wet surface was as much as five car lengths…

Porsche feels it’s too early to comment and that at this stage it is still a matter for the tyre companies. Once the regulations have been set, the German car maker will still request an appropriate level of performance from Michelin for its top models.

So what does the future hold? There will still be high-performance tyres made from a race-style compound though they are likely to have regular road-car tread patterns. However, they won’t be as fast or responsive as the current crop of trackday tyres, and for those of us who enjoy the extra performance and challenge presented by this specialist rubber that’s a real shame."

Time to start stocking up on RE55's and the like....thoughts?

I can't see the Japanese tyre manufacturers giving a fark about the UK's tyre laws. They still have ultra high performance road tyre offerings that will meet those criteria.

There's also a big enough market in the rest of the world to not bother changing their production line.

Aus might follow suit if USA did it, but I doubt the UK's changes will have any influence here.

Toyo might bring the RA01 back (assuming they're still tooled up for it). At full depth it would be the best performing street legal tyre bar none in the wet. And it wasn't noisey. Should easily pass the tests. Buff it down for track use, and its a completely different tyre - everyone's happy.

I can understand the law makers having issues with the safety aspects of them in regard to the wet grip, but to ban them because of noise and rolling resistance is just BS.

It will be interesting to see what the tyre manufacturer's come up with though :)

Just anothe example of the way the UK is becoming a nanny state, and lets hope Aus doesnt follow suit

Yes semi-slick tyres perform worse in the wet, but what about the improved performance in the dry?

Yes they could be dangerous for a driver that doesnt know this, but every track car enthusiast knows that they dont stick as well in the wet and drives accordingly, or keeps it in the garage on a wet day.

Dont ban them, just make sure that when someone buys a car with these tyres that the are fully aware of the reduction in wet performance.

Id like to see a comparison of an RE55 in the wet with a Ling Long tyre from China. Should they also ban budget tyres?

or how bout the fact that we still have to adhere to the same (or lower) speed limits that were initially applied to cars 30+ years ago, when even the best tyre on the market at that time, performed worse in the wet, than a modern semi-slick?

Like pretty much every issue that comes up these days, the answer isnt tougher laws or bans, but in education and training.

either that or we should have a world wide extermination of stupid people...i like that idea most

The aim of the new regulations is to both raise all-round performance standards and to give buyers a greater understanding of the performance and environmental impact of each particular tyre before purchase.

Pass? There is no pass or fail, it's a rating, printed on the sidewall. Just like the current treadwear, traction, temperature, load carrying etc. All that happens is there are a few more ratings printed on the side of the tyre so the dumb asses have no excuse for complaining that they didn't know that their new tyres where noisy, or used more petrol etc.

Nothing to worry about, move on.

Cheers

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
