Tyre dressing only lasts on a clean, dry tyre. Clean the sidewall with a tyre cleaner until the brown haze is gone, let the tyre dry, then apply a thin coat of tyre dressing with an applicator. If you want to make tyres black with a calm, matt look, choose a water-based dressing. If you want a wet shine, an oil-based dressing is the better fit.
That brown haze is not dirt you can blast off with the pressure washer. It is old dressing residue, road grime and rubber that has oxidised. Put new tyre shine over it and it bonds poorly and goes patchy. In the workshop we always clean first and dress second.
Choosing tyre dressing: matt, satin or wet shine
The difference comes down to two things: the base and the gloss level. A water-based dressing usually gives a quieter, matt or satin result. An oil-based dressing usually gives a deeper, wetter shine. Which one you pick depends on how you want the car to look.
Look you want | Product | Why |
|---|---|---|
Matt, like factory fresh | Nourishes the rubber and leaves a matt finish. | |
Satin to gloss in layers | Water based and layerable: more coats give more shine. | |
Wet shine | Oil based: one coat is subtle, more coats give more gloss. |
You will find every dressing for tyres and dark plastic in the tyre dressing category.
How to do it
Wheel first, tyre second. Clean the wheels first so no dirt splashes back onto a clean tyre (read our guide on cleaning wheels without damage). Work one wheel at a time and in the shade so products do not dry on. A suitable cleaner is in the wheel cleaners category.
Use a tyre cleaner. Spray the sidewall with a tyre cleaner. Shiny Garage Pure Black Tire Cleaner Concentrate dilutes from 1:5 and tackles baked-on brake dust and asphalt particles. Koch Chemie RFS Reifenschaum Tire Foam Cleaner is a foam that works into the tread pattern. Let it dwell briefly, but never let it dry.
Scrub until the foam stays white. Use a stiff tyre brush, not a household brush. If the foam stays brown, there is still dirt or old dressing on the rubber: repeat the step. The colour of the foam is your gauge.
Rinse and let it dry properly. Rinse the tyre well and wait until it is dry. Dressing on a wet tyre runs off and leaves streaks. Dab it with a dry microfibre cloth or let it air dry while you clean the next wheel.
Apply thinly with an applicator. Put the product on an applicator rather than straight onto the tyre, which keeps the wheel rim and paint clean. A foam pad such as the Chemical Guys Car Wax Foam Applicator spreads the dressing evenly (more options are in applicators and foam pads). One thin coat is enough to start with.
Let it settle and wipe back. Leave the dressing for a few minutes and wipe off the excess with a microfibre cloth. For Coco Tire Booster that is after about five minutes, for Back2Black after roughly ten. Pitfall: a coat that is too thick will sling onto the paint as you drive off. If you want more gloss, add a second thin coat instead.
Aftercare: keeping tyre shine looking good
We wash in a fixed order: wheels and tyres first, paint after (see washing your car without scratches). That way shampoo does not strip the coat before you are finished. A dressing stays visible as long as the tyre does not get dirty again: for Back2Black, Shiny Garage states 4 to 6 weeks. When the shine fades, give the tyre a quick clean and apply a new thin coat. Building on a dirty layer gives the patchy result we started with.
