Can you use them? Yes.
Should you use them? Depends on what you are looking for. Most of the times (not always) these special tires are just a modified version of a regular tire.
What makes them special? Here is a list of common modifications:
- A softer compound. This typically increases grip at the expense of longevity.
- A special size. Sometimes car manufacturers require a tire in a very specific size. This is common for more expensive cars.
- A higher speed rating. This means that the tire will be rated for higher top speeds. Usually carries a list of modifications mostly known to the manufacturer themselves. These are special tires sold under the same brand for marketing purposes.
- Special decoration. Yes, we are that vain. People sometimes just want a tire that elevates their status through branding. Ever wonder why Pirelli PZeros on Ferraris have that unique logo with pink/rose coloring?
Now the tires you mention:
Michelin Pilot Super Sport R18 225/40R18 88Y and 245/35R18 92Y
These are performance tires with a very low profile. You might want to look at similar tires and compare based purely on specifications (and price). Take into consideration the type of driving that you will be doing. Don't buy performance tires for a car you plan to daily drive in various conditions. Its a recipe for disaster (learn from my mistakes).
