Yes, it is possible to true a wheel with the tire still on, but it may be more challenging and require special tools.
To true a bike tire for optimal performance and safety, follow these steps: Use a spoke wrench to adjust the tension of the spokes. Spin the wheel and look for any wobbles or unevenness. Tighten or loosen the spokes as needed to straighten the wheel. Check the tire pressure and adjust as necessary. Test ride the bike to ensure the wheel is true and the tire is secure.
Common signs that indicate a wheel is out of true include wobbling or shaking while riding, uneven tire wear, and a rubbing sound when the wheel spins.
Check your tire pressure, true
If you are asking what holds the tire on the wheel it is called a bead on the tire. On the wheel it called the rim.
