I have the Pirelli Scorpion Weather active tires and just love them. I chose those over the defenders because most of my driving now is road trips so I preferred a road tire. If you will be taking your expy off-road often or somewhat, you should consider the defenders. They are both great tires.
In my close to 6 decades of driving, I've purchased a lot of tires. When I was younger, I would get the cheapest tire I could find. As I got older and wiser, I learned about the ride quality, mileage, directional vs. non-directional and treadwear. I ended up being a Michelin fan.
My 285/45 R22 Michelin Defenders LTX M/S are Super quiet and last longer, compared to my Scorpion WeatherActives I had on one of my vehicles. They also don't throw belts and have very even treadwear for such a large tire.
Both tires are great choices, and the Scorpions may be better for colder snow regions. But for smoother daily driving, treadwear and long-distance trips, as well as hauling, Defenders out performs the Scorpions. Another important factor is Directional vs. non-directional. I switched to Defenders because the Scorpion Weatheractives are Directional, while the Defenders are non-directional. This is a huge plus when it comes to rotation of the tires and even treadwear. I have horror stories about treadwear and the extra cost to move the passenger tires to the driver's side.
With that said, I found this comparison.:
Key points to consider:
Winter Performance:
The Pirelli Scorpion Weatheractive excels in snow and ice thanks to its dedicated winter compound and tread pattern, making it a better choice for areas with harsher winters.
Tread Life:
The Michelin Defender is renowned for its exceptional tread longevity, offering significantly more mileage compared to the Pirelli Scorpion Weatheractive.
Overall Handling:
While both tires offer good all-season performance, the Pirelli Scorpion Weatheractive may provide slightly better wet handling due to its aggressive tread design.
Driving experience
Michelin Defender tires are designed to provide a sporty and reactive driving experience, especially when turning. Pirelli Scorpion WeatherActive tires are designed to offer excellent wet performance and snow traction.
Who should choose the Pirelli Scorpion Weatheractive:
Drivers in regions with frequent snow and ice
Those prioritizing good wet weather traction and winter capability
Who should choose the Michelin Defender:
Drivers looking for maximum tire lifespan
People seeking a quiet, comfortable ride with decent all-season performance
