How do tire and wheel companies prefer to be approached for sponsorship?

First, do basic research: make sure they actually make a tire for your application, that it's legal in your series, and that it's competitive for your class. Companies like Atturo say it's an immediate disqualifier when someone asks for a tire they don't even make. Try buying and using their product before asking for sponsorship - brands want people who already have affinity for their products, not just those seeking free stuff. Reach out through social media or their website, but make your pitch direct, personalized, and short. A 20-page deck won't get read. Finally, understand their business model: some tire companies primarily sell to racers (endemic sales), while wheel companies like Wheel Pros are focused on growing consumer demand - only 3% of cars have custom wheels. Tailor your pitch to help them achieve their specific goals.
