GRIP Tyre softener???

[Jon]

I was asked my opinion on this product today... http://www.griptyresoftener.com/
I've never even heard of the stuff before. On paper it seems to be a good idea, Although I'm not sure i like the idea of a chemical that breaks down/softens the rubber compound and as such i wouldn't use it.
But, Have any of you guys had any experience of this magical liquid? Or will it be about as much use as Anne Frank's drum kit?

I tried it a couple of years ago on some old tyres I had. It certainly softens the tyres. Pre treatment they were hard as hell. Post treatment I could put a fingernail into the tyre and the mark would stay.

Apparently it's used lots in karting.

Thanks Stu,
That's what i thought. I have visions of tread blocks detatching from the tyre on hard cornering and probably worse.
As said before, I'd never use the stuff. Just interested in case i get asked again.

Did you run the tyres after treatment Tommy?

I'd be terrified of the layers of the rubber being altered so that the top layer would almost delaminate from the harder layers that weren't treated. I've seen guys using at Santa Pod and the ones that do all go quick enough to assume it works.

As someone that sells tyres (ie John) I would give it a very wide birth indeed.

Yep I think I ran them at Marham and another trackday after that. No delamination. I still have the remainder of the tin in the shed and will use it (if I can be bothered) on some 2nd hand Kumho V70As I have.

Fair play. Experience beats heresay

[stockcar]

can also verify that it works..........

had a few sets of old rally "wets" that a customer insisted on using and were so hard he may as well have used slicks (winter events so extremely cold also)........treated them 2-3 times as the instructions and were fantastic in their change - he used them for approx 4events after that with no issue and saved himslef the cost of new tyres

we did find they needed time to "cure"

Yes,

I have also used it to good effect.
