I`ve googled this and got many different answers, but since this is an eco recycle friendly forum and so many knowledgeable people write here, I`ll give it a try.

I have a set of 8 year old Michelins with a lot of tread and overall excellent condition except the tread which has become too hard. It squeaks a little when taking turns and overall grip is lacking so it`s a safety issue I`d like to solve.
Are there any home made solutions for softening the tread? I just feel bad about scrapping these tires and want to find out if they can be rejuvenated anyhow.

Right now I`m putting diesel fuel once a day on an old spare tire to see how it goes and it does seem a little softer, but any proven solutions would be appreciated.
People advise all sorts of paint thinner, kerosene, ATF but I`d love to hear for a permanent solution, if it gives me just a year more of life on these babies, it would be awesome.
