Okay I have put about 23500 on my coupe.
I think it's time for me to change the tires on the coupe. However I have came up with few questions.

first, do you guys think I should change the front tires as well? I think front tires are still in good shape but I think as handling wise I should change all 4 tires howeverI can be wrong.

second, Will the handling dramatically effect by it if I only change the rear? Is it dangerous to keep the front tires?

third, I should stick to pilot if I am not going to change the whole set, right?

With that many miles on the tires I would chane both. I mean if you had sain I need new rears at 10k than that would be another story. Also it's nice to hear someone else getting good mileage so to speak out of the ppilots. I've got almost 23 on mine now. I just wish my rims would get here cause the stock tires have to go soon.
