Did you really got 30K out of your tires? That is very shocking!! I mean in the good way!!! I had 17K out of the Michelin Sport, 15K out of the Yokohama ES100. Now, I have the BFKDW2 tires. Hmmmm, do you have a sedan or something? because the coupe mostly dont have this 30K on these tires, I have a 04 with tires &wheels 18's package.

 

I have a Coupe with the stock 18's. My car is also lowered on H-Techs, but I got the alignment back into factory specs. I am pretty surprised as well, since I see most people get less than 20k miles. I've never tracked my car on these tires, but I do auto-x often.

 

As stated above, just replace the one that has the nail. No need for both with only 4k.
