Another new trick...
 

Spray any brand foaming upholstery cleaner on your tires before washing. They should be dry. The results are a nice soft black tire with no dressing needed.

I noticed the thread about PS fluid for rubber. Years ago we used brake fluid. Really looked good and natural. Then along came Armourall. Well, I don't use too much Armourall so I'm always looking for alternatives.

Very nice. I am about to wash my car in a few minuets, and I have some upholstry claner that I will give a whirl with on my tires. Thanks. And I will try brake fluid on the wing and rubber, thanks again

Brake fluid can be very damaging to paint. I'd be careful putting it on a wing where it could easily flow onto painted parts of your car.

Brake fluid is VERY damaging to rubber. That is why brake lines have at least two layers. The internal layer is glycol resistant, the outer layer is oil resistant.
Very few countries allow the production of brake cylinder cups out of natural rubber, and those that do require the use of DOT 4, but still have short lives.
