I have been running the Pole Positions on my Mustang for 2 years. I have put about 15k on them and have not experienced any excessive wear.
They are awsome tires. I went to them from a BFG gForce and I will never go back. They stick like glue. With the BFG's I could squeal 1st through 3rd no problem, with the S03's I can only get 1st and a slight chirp in second, then I'm gone. I took a Full circle exit ramp at 55 mph, no loose condition, no rear end shake, no barking hound dog noise out of the tires (you know that "ooorrrhh, ooorrrhh, ooorrrrrhh" sound)
The few time that I have been cought out in the rain, I have not experienced any hydroplane or loose conditions on the highway. My only problem with wet traction is a heavy foot on the take off.
the only draw back to them that I can see is that they are soooo sticky, they pick up every little pebble and stone and sling them up into the fender well at low speed and it sounds like you have a 5th grade drum corp in your trunk. This may not be a problem in a well insulated LS though.
