Tyrewarmer ban.

Or maybe they want to 'dumb' down the tire development so they can keep up

Some interesting points as regard to road safety in this.

Do you think there would be less pedestrians injured if cars where able to pull up within a shorter distance due to better tyres that didn't skid as early or worked better when cold? Or would there just be more nose to tail accidents?

Or is it just drivers don't have the skills to drive to the conditions or responsablity obey speed restrictions.

Mehhhh i don't know if id be keen !

They don't have any competition as they are a sole supplier aren't they? Just like Pirelli in WSBK.

This is by far the bigger percentage!

ahhh true....sorry thought we were talking bikes again....it was tongue in cheek anyway ;-)

No one is going to purchase tyres for a ford laser, that will only last 2000ks but will stop if someone jumps out in front of them.

Warmers are a tyres comprimise - all tyres will work better when warm. just like oil - they can make a product that works well when cold - but it will always have to work when HOT

Riders don't have to wait for tyres to get to temp if you make tyres that grip straight out of the bat then the first 5 laps will be fast as and then high sides and low sides after 10-15 laps when a GP bike or superbike lays the power down.

there are tyres out there that don't require warmers - they are wets.
ride on those when its not wet enough - they last 6 laps max on my 400!! then your stepping out everywhere - screwing your tyre in the process. costing you MORE $$$$

F1 is where money needs to go - people go there to have the highest end gear - fastest bike - best brakes etc. if you wanna race in the highest formula in NZ then STEP UP.

With all these controls coming into the PREMIUM class it will turn into another production class.

it seems that the class with the least rules is F3!!

Nah I did not miss his point - I just thought about it before replying.

A motorcycle road tyre that works equally well from cold as it does at normal temperature. Considering tyres are global you are looking at a air temp of between say 0 to say 38 degrees..........something has to give on that perfect tyre.

As for tyre warmers and racing - WTF is the point of banning them at the top level - it's not cost, do they want more spills in the first 3-4 laps to bring some excitement to the sport?

F1 constantly mucks around with the rules to the point that it is absolutely boring.

WSB racing is tight and exciting and on a control tyre - why remove tyre warmers?

So what do you think is driving Bridgestones desire for no tyrewarmers? Its certainly not to please the teams and drivers.

I admit to being totally blank on this one - the only thing I can think of is that Bridgestone has actually invented the 'ideal' race tyre - one that does stick from cold and survive the entire race.

I have a small hat prepared in the event I need to eat it (it's chocolate)

Maybe they have taken the multi compound tyre concept to a new level. As well as different compounds from centre to side, actually have a different external layer of soft rubber that sticks well from cold, then wears off after say 5 laps.

Im not even sure its Bridgestone that are behind it. Maybe it is considered that by making the drivers start on ambient temperature tyres it will require more skill from the driver to adapt to the changing conditions. Alot of talk has been made of the fact that technology is winning races and the drivers role is not as significant as it could be. Perhaps the intention was to give driver skill and adaptablity more influence in the outcome of races.

Just knocking around ideas.

Would the lack of tyrewarmers make the racing any less appealing to the spectators. Why are the drivers upset. From what I gather its safety because of the difference between a car leaving the pits on cold tyres and someone whos already up to speed.

in the motogp, i think they should use any technology available to them at the time, its a showcase of what people can make/do.

wsbk, they should ride bikes as you buy them off the floor, no mods allowed

The same applies the other way around.

Today's tyres can only operate reliably in a narrow temperature bracket.

In this country, they close down roads if there's an inch of snow on it...

I'm sure motogp/wsbk/v8 will help tyre manufactures to understand how their compounds reacts and works in different environments.

I don't remember Welly being that cold! Windy .. Yes! Horizontal rain in winter ...YES!

How many people have tire warmers fitted to their roadbike or car before they go out for a ride or drive.

The use of tyrewarmers is doing nothing for the development of road tyres and the rubber being delevoped has no real world use except for the racetrack. If tyrewarmers where banned and tires had to be fitted at ambient temp the tyres developed would instantly be of benefit for roadusers.

When do you think tyrewarmers may be banned in WSBK for example? It may be sooner than you think! When tyrewarmers are banned in Formula 1 how many years later will the same happen in MotoGP or are the two so completely different that the comparsion is irrelevant.

Yeah! And worse still is all the noise that the generators make! AT race meeting, sure fine, but now every second bloke at a trackday has them and it's really hard for old fellas like myself to have a bit of a lie-down between sessions with all that racket!
