I didn't opt to pay the extra money upfront to purchase a T5 (regret it) but that's how it goes. So therefore I am not looking for any kind of track, racing or performace tires. I would just like to know everyones opinion on some reliable, efficient, long lasting tires for our babies? I'm on the original set of tires that came on my s40 and they've lasted me a little past my 45,000 mile service. Has anyone found a reliable, inexpensive tire that i could purchase and say not have to worry about replacing for a good 50,000 miles or so? Any imput will be appreciated.
