No, heavier by the weight of the extra air put inside it.
Even if you filled the tire with helium it is still heavier, although the additional weight would be less than the additional weight of air.
When a tire is properly inflated it will be level to the ground. Over inflated and the middle of the tire has the most pressure on the ground. Under inflated and the sides of the tire have the most pressure on the ground.
The same as a tire that has not been inflated.
Any tire inflated with a gas (air or nitrogen ) is a pneumatic tire.

less inflated.
A deflated balloon is lighter than an inflated balloon because the air inside the inflated balloon adds weight to it. When the air is released, the balloon becomes lighter because it is no longer burdened by the added weight of the air molecules.
physical
you can try to tell by gripping it, if it is firm then it is fully inflated. if it is kind of squishy, then it is under inflated. With a pressure gauge.
it is actually smaller
In the middle of the tread area,
it helps with keeping the tyres inflated.
Most likely under-inflated tire
