Maybe not the first detailing product you may think of but after using a number of different tyre dressings/treatment for my car, I have now found my favourite.
Meguiars Endurance Tyre Gel 
It's got a lovely waxed showroom finish and is easy to apply. Not only this but you only need a tiny amount to do all 4 tyres. Priced at £10* for 473ml considering you use so little each time; it's good value and my favourite finish with no waiting for it to dry or covering half your alloys in the process, thus wasting the product. It also stands up to its name and lasts better than any other product I've used.
A great budget option is Car Plan's Wet Look tyre shine - spray it on in seconds, you get a nice wet look but it doesn't last as long. £5 for 500ml, and readily available.
My most disappointing product would be Autoglym's Tyre Dressing, as it has a poor method of application where much of the product is wasted and hardly lasts 48 hours. At £7-8 a bottle it's not good value and is my least favourite of the Autoglym product range, which normally I would recommend.
I'm a decent detailer with serious OCD, however there are some guys/girls on here who take it to another level! I hope that you can add some extra hints & tips to this topic.
