Bikes styles all have different tires to suit terrain. There are road racing tires, cruising tires, off-road tires and many different wheel sizes too.
Bicycle tires and other bicycle related parts and accessories can be purchased from several different businesses in Ireland. Hartford's, Dublin Bike, XX Cycle, and Nigel's Cycles are just a few of these businesses.
It depends on the rider. My bicycle is a different size from yours because my legs are a different length.
Turning on a bicycle is different than in a car. When you turn on a bicycle you lean the entire bike to the side. This causes the sides of the tires to contact the pavement. The tread on the sides of the tires is there for this exact reason. Without it, you would probably skid out when you try to turn.
The material that is used to manufacture Continental bicycle tires is rubber made from the Uniroyal company or other companies that specializes in supplying rubber for bicycle tires. To get a more specific answer to the question, a visit to the local bicycle shop can render an answer.
Basically, you can't. Car tires comes with year of manufacture printed (in code) on them, but no such thing for bicycle tires. What you can do is judge them for dryness, mount& inflate them, and look for cracks.
Bicycle tires can be bought and replaced easily at many biking stores. Bicycle Warehouse, Performance Bike, and Bicycle Tutor all sell replacement bike tires as well as teach one how to replace a bike tire.
Bicycle tires start at a little over 3/4 inch for high speed racing tires, going up through 1.5 inch for light road going tires to 2.25 inch for knobbly off-road tires.
Bicycle tyres come in a lot of different sizes. I'll post a link below.

Air fille bicycle tires were invented by John Dunlop.
You must be buying cheap tires. I find almost no flaws in bike tires that I use.
Not all of them have. Bicycle tires for soft/loose surfaces will have coarse treads and very knobbly patterns.But bicycle made to be ridden on hard surfaces will have very smooth treads.The main reason why car tires for road use have tread patterns at all is to avoid aquaplaning. And due to the shape and size of the contact patch of a bicycle tire, a bicycle can'taquaplane. So small/no treads will do fine.
