The first step is to rinse off all the loose dirt using your spray nozzle or the pressure washer. Try to work the water from multiple angles - above, below, and both sides.
Then, scrub them with the bristled brush, warm water and dish soap. Once your tyres are glistening, you can start washing the wheel surface by using brush along with warm, soapy water.
The perfect final step to get your tyres looking their best is to apply wax. After applying the wax, give it a final polish with a micro fiber cloth for that extra shine.
