if drive regular, how long do htey usually last ?
maybe like 30,000 miles?

I am not easy on my tires and I still got 26K out of the stock GS-D's They are currently on my car waiting for my new wheels to arrive. If you drive normally you should at least get 35K-40K

i got about 35k on my gs-d's..

I got 26K on my pilot sports.

wow, so i guess 30,000 on stock tires sounds right.

I got 22k on my Eagle RS-A's

Got almost 30k on my Bridgestone and perhaps go 5-10k more.

My rear pilots lasted 26k
My fronts are still going at 28k

My Goodyear RSA's are toast at 16k, at least the rears. The fronts may go to 20k.

I have about 21k on my pilot sports, the back are tread less and the front still have about 2k worth of life left. Regardless, I'm still going to get 4 new tires sometime this summer.

I got 14K out of my rears. Swapped on some S-03's. I kept the front Pilot Sports as they still had some life left, but will probably just be used in case of emergency.

I got about 15k from my rears......

I got 13k miles and the tire noise are driving me crazy

I got about 25k miles from the rears, fronts tires still orig. about 30k mile now but starting to feather now on the insides...
