Street Tyres On The Track

[Bullet32]

I am glad to hear that you were treated well Tim, we do try to keep a very proffesional attitude and talk with customers on a one to one basis.

Unfortunatley this kind of damage does happen to low profile tyres when they are run flat.

It can happen with only a few rotations of the wheel as the weight of the car pushes the wheel down onto the inside of the tyre and the outer and inner lip of the rim act like a circular saw cutting the wall of the tyre.

This is NOT a "Federal tyre only" problem as no tyres are indestructable.

I hope that you are still happy with your tyres and that you will consider Federal's when you next need a set as I believe that they are the best value for money tyre available.

P.S. For a street legal competition tyre please visit www.federaltyres.com.au and have a look at the 595RS as these are a great tyre for racing and track days, I personally have driven on them and they have heaps of grip.

They have always been run at manu recommended pressure

This may be part of the problem, the "manufacturer recommended pressure" is way lower than you should run them for performance. Manufacturers specify pressure for comfort since that's what 98% of people want.

My Pulsar SSS used to recommend 26psi in its tyres. I never ran them below 32, and put them up to 36 for the track.

A tyre that's underinflated for the amount of stress put on it will fail due to excessive flexing of tread and sidewall. The more stress the higher your minimum inflation point.

You are welcome to your own opinion but making statements about brands or manufacturers on these forums that could be classed as detrimental to the product is not such a good idea, there are many sponsors, retailers and workshops that take part in these forums that could see these kinds of statements as an insult or worse - defamation.

Please dont take this as any kind of personal stab or threat I am mearly making a point.

understandable, but your are hardly in a position to be objective, working for federal, and i also admit I probaly should not have made the generalisatoin about the carcasses (which is tecnically not correct) but the delam issue was a real issue early on (not the 595RS) and was experienced by some of 'your' drivers... i know as i helped suggest/work out a few setup remmedies.... in fact i even did a days worth of drifting on them.

as i mentioned in the orginal post i also pointed out that the run flat was the cause of the failure in this instant not the carcass.

I remember having this discussion a while ago in another thread, but are the 595RS an R Compound tyre?

The treadwear rating of 180 is a lot higher than most R Comps. That figure puts it more in line with a Falken RT215 / RT615, which has a semi slick pattern but is certainly not an R Comp.

URAS - Youre correct in saying that I have a bias opinion (it would be hard not to, working for Federal) but what I said is true, it could be bad if someone decided to take comments on here seriously, I believe it has happened before. No hard feelings though, Im not here to start problems.

The earlier "SS" 595 had some teething problems with drifting but were always a very good street tyre and were still made to the same high standards as they are today however the "SS" 595 was re designed and the compound changed to better suit drifting aswell as being re named simply as 595.

It is now a very succesful drift / street tyre and we are very happy with the way it has performed since the slight changes were made.

Scathing - The 595RS is not an R compound tyre and is not listed on the CAMS list of grooved slick racing tyres therefore being considered more of a "street semi slick".

The tread rating is 180 which is higher than R comp (50 - 60) but treadwear ratings dont tell you everything about the compound, the rating does tell you how fast the tyre will wear but the secret to the tyres performance is in the tread compound, tyre manufacturers rarely give out information on compounds as they are unique to every different tyre type and it would be like KFC advertising their 11 secret herbs and spices.

I have driven on and tested the 595RS myself and it is very impressive, we have also had these same tyres on track / drift cars and the feedback that we have had has been extremely positive.

There is only one way to find out for yourself though...
