Reviving semi slicks

[kingmick]

I applied the WD40 and I can't say anything amazing occured........yet.

Where I applied a single application it took a while 3 hours+ but it eventually evaporated/soaked in but even this morning the tyre still felt greasy/oily which is a bit of a concern.

I will report on the section that had a heavy application and has been covered in glad wrap after I check it tonight.

Initial findings are not that inspiring

How about if you put the WD on and then put it a plastic garbage bag and seal it! might help it a little??

One is wrapped in glad wrap, it's sealed enough that it still looked pretty "wet" under the glad wrap this morning, I'll unwrap it tonight which will have given it 24 hours and see what the effect has been.

Great minds think alike then! lol

Haven't tried this, I take no responsibility, but you could try methylene chloride - on a test patch - diluted. Very nasty stuff, don't breath it in, or get it on you, it can give you liver cancer

I've heard of castor oil being used on really really hard tyres, aka vintage restoration.

Rubber industry has been searching for a way to break the sulfur bonds in the rubber polymers for a long time so that rubber can be recycled.

Not worth dying over mate might give that one a miss

i've heard of tires being soaked in diesel...? but then again i think thats more to get them smoking quicker then anything.

Yeah that's a trick for burnout comps.

Well I unwrapped the WD40 coated section of tyre last night, wiped away the excess WD40 with a clean rag and began having a close look. It appears to offer SFA difference in my opinion other than blackening the tyre a little and making it oily.

I rigged up "softness tester" using a spring, a 2x2mm metal rod and some vernier calipers. I tested several sections of tyre that had and hadn't been applied with WD40 and could find no difference in penetration (softness) measurements.

I cut a slice of tread off and it appears the the WD40 doesn't penetrate much at all (one pass with some wet and dry across the tread seem to take the tread back to it's pre WD40 state).

In summary - don't waste your WD40 on tyre reviving, it doesn't appear to soften them and the increase in grip/friction appears to be nil or worse due to the oily layer left by the WD40.

Nice work Shane. Have to spend the bucks on the good stuff by the looks. If it works on a heavy-ish car as well as it did for MJH then some worthwhile info for all of us who can't afford fresh tyres every time we head out for a fun track day.

Just remember to follow the instructions on the can EXACTLY.

And don't get it on the skin as it burns like a bitch.
When I did the tyres I had they got wrapped in glad wrap between coats so might want to try that as well.
