Thanks to its DuraSkin™ anti-tear fabric and two Vectran anti puncture strips, the Grand Prix 4-Season holds up under extreme conditions. In the Paris- Roubaix race, the "Hell of the North", cyclists equipped with DuraSkin™ enhanced tyres have the fewest tyre related problems during the race. Incorporating our special wear resistant carbon compound, the tyre is characterized by very good mileage performance as well as excellent adhesion on wet roads and at low temperatures.
With 23, 25, 28 & 32mm versions, the Grand Prix 4-Season makes it possible to select the right tyre for various road qualities, type of bike and comfort requirements. A double Vectran™ Breaker belt under the tread raises the puncture and cut protection to the highest level available on the market. Featuring a total of five plies beneath the tread, plus a sixth Duraskin layer, it's ideal for rough sportives and general bad road conditions.
"Puncture resistance is way above that offered by the fastest race tyres yet rolling resistance feels pretty similar. Grip is excellent, particularly in the wet." Grand Prix 4 Season - 9/10 - Cyclist.co.uk

How to check your current tyre size?
Take a look at the sidewall of your current tyres and you’ll see one or two sets of figures;
One is the traditional size like 700x28c or 27.5x2.2. The first figure is the tyre diameter(size). The second is tyre width. Note: road bike sizes are in mm, MTB sizes are in inches.
The other set of figures you may see is ETRTO sizing like this 28-622. The first number here is tyre width while the second number relates to wheel diameter.
Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

Will this tyre fit my wheel?
Your new tyre must be the same diameter as your current one (to fit your wheel rim).
Then, you need a choose a tyre which will fit your frame.
Road bike tyres are generally 21 – 28mm wide
MTB tyres can range from 1.5”-5”
To make things complicated road tyres are measured in mm, while MTB tyres are in inches.
How wide is too wide
You want to leave at least 4mm clearance between your frame and tyres to prevent rub and allow for mud clearance.
Measure the following areas on your frame:
Fork crown (top)
Brake calipers (make sure you squeeze them)
Chainstays
Seatstays
Subtract 4mm and you’ll have the maximum width your frame can handle.
