Reviving semi slicks

[kingmick]

Trouble is its only on the top layer, this is why none of the circuit racers use it. It works for of the mark, but an old tyre will always be an old tyre!
It might be ok for the first run of a short hill climb for a good start etc, but that is all, once you scrub that layer off its still an old tyre!

Justen, I'll spray some WD40 on some old Azenis RT215s I have at home tonight and see how the rubber reacts. I won't be testing them on the car but it will be easy to tell if they soften up at all.

They aren't an R-compound tyre but they are quite soft when new and these ones are now rock hard so I'll see if it makes a difference..

Should be just what is needed then

Yeah i can see it's aussie I just would have thought it's not a product you could post...being flammable and all? I'll give them a call

I wasn't hoping for miracles Kingmick but what we used on cart tyres would get us thru 2 sessions (heat and final) so i was hoping the same would be true for car tyres on a short hillclimb style event?

Thanx Shane, very curious to see what you reckon ot does

[kingmick]

Kart tyres are much much softer compound and they spend 99% of there time inside{out of sunlight} and they dont go threw the heat cycles like most car tires etc.

If it worked, most circuit guys wouldn't have to change there tyre's every round to have a chance of winning just a thought!

Yes they would because the product is illegal to use

Or they haven't read the info on the WD40 website* Just a thought.











*Just kidding, we are only talking about getting one last run out of some tyres before binning them. The tyres are going to be used regardless so anything to make a slight improvement is a bonus.

I think you are missing the point Kingmick...far from saying this is ideal. I just have a set of semislicks with tread that i want to squeeze one last event from. I'm being a cheaparse to have a bit of fun, not looking to win a world championship

Yes but at $2000 a set and when its never checked unless you were to paint it on in the pits, the state guys and some national guys would do it in a heart beat!

I know your kidding, because it would be a very cheap way to make them work

No, i get the point thats why i said it would only work of the start and for a bit on a short hillclimb
Anyone that drives hard knows how much there tyres bead off and the affect of the softener would be from the start and maybe for the first two corners depending on the corners etc!
Will work even less on semi slicks than soft full slicks

LOL "anyone that drives hard" thanx mate, i'll just get back to my knitting then shall i

If it's such a waste of time i'll save my pennies and just go with the backyardie WD solution if Shane's little Mythbusters experiment produces results. See how they go, even one good corner will be better than nothing.....of course at my snails pace i could even get a lap or 2 out of them

Here's my WD40 test plan:

Spray WD40 onto a section of one tyre and see what happens, poke it a bit and compare the "softening" and "feel" to the area of the tyre not applied with WD40.

On the other tyre, apply a heap of WD40 to one section of the tyre, wrap with glad wrap, allow it to soak and check it 24 hours later for "feel" and "softening".

Then cut into both WD40 treatments with a blade and see how far (if at all) the WD40 penetrated in both applications.

It'd be nice to do it with tyres on a rim and drive on them but it's not going to happen this time so we'll just see what changes I can notice (if any).

what u need is a nifty lil gadget that measures the hardness of the tyres

one of my racing mates had one...total wank i thought, but they used it whenever they bought tyres to get the 'softest' set

[JustenGT8]

Sounds like a good plan Shane....Jamie would be proud

i think you may find that "poke it a bit and compare the softening" is gonna get quoted in a few sigs though

Drop me a line and i'll swing by to suss out the 'after' result.

BTW i asked Simon and time's a bit tight for your brake mods at present, bummer.
