Hello. I bought a 6mt 2006 g35 coupe back in April. When I first got the car, it was fitted with 4 accelera phi tires, 19 inches.

After driving for few months in brooklyn, ny, my front left, driver side tire exploded after going over a pretty deep hope, forgot the correct word for it.
anyways, I went to a tire shop, and they didnt have the same brand, so I thought it was ok to get a different brand, different tread tire. The cheapest one they had was Nankang Ultra Sport NS-II. So far, I haven't noticed anything wrong while driving, everything is smooth. even while driving 80 mph in the highway. Haven't really gone any faster than that.

But suddenly a question popped up, and after doing some googling, seems like the general consensus is a big no no for my kind of situtation.

Is it ok for just normal driving or am i putting my self at a risk by having a different tread tire in the front?
