__ valve stems normally are not replaced, but may have rubber washers or O -rings that may require replacement when new tires are installed. a. Rubber press-fit b. Screw-in c. TPMS Tensor-integrated d. Brass fitted

## Step 1<br />The problem is about the type of valve stems that are typically not replaced when new tires are installed, but may require the replacement of rubber washers or O-rings. The options provided are Rubber press-fit, Screw-in, TPMS Tensor-integrated, and Brass fitted.<br /><br />## Step 2<br />The TPMS (Tire Pressure Monitoring System) is a system that monitors tire pressure and alerts the driver when the pressure is too low. This system is integrated into the tire valve stem.<br /><br />## Step 3<br />The TPMS is designed to be durable and not to be replaced with the tire. However, the rubber washers or O-rings within the valve stem may wear out over time and may need to be replaced.
