I have about 5,000 miles now on my GS-D3's and they are very good. Right mix of grip and enough better ride to feel the difference. The hard turn 'feel' is not as solid as the run-flats, so the feeling of confidence is not as strong, but I have yet to make them break out and slide and I have tried.
I run them at 35psi cold and when they get off that I notice so I regularly check it to see that they are up to 35.
Bought em at Americas Tire (CA) ..Discount Tire everywhere else... been buying all my tires there for about 15 years, Texas, Georgia, Colorado and now California.
I dont know the Bridgestones but I try to buy American.... hate to send my money to Japan. They make good stuff, but I just dont do business there.
