I haven't had any experience with the Pirelli Scorpions, but Pirelli has been in the business a long time and you don't get there by putting out junk. I DO have experience with BFG T/A KO tires. They are one the best for light trucks and SUVs, IMO. They have great traction in any weather and long tread life. They give off a slight hum on the road, but to me the hum, like exhaust rumble, are a good thing.
For the price difference, I'd definitely go BFG. I doubt the Pirelli's last any longer, although they are probably quieter. Just my 2 cents.
No thanks for more furry friends. Our 2 cats and a dog are more than enough for our modest home.
