I want to explain something after reading this comment: (someone smoked a lot before writing this I guess)

My 4 sets of tires lasted 118 k miles
First original Dunlop set lasted 32 k, two replacement sets from American tire depot (made in China) lasted about 28 K each and the last set (made in Thailand) lasted 31k
The last set was the best (no flat spots)
Also I always replace tires at 3/32 minimum depth
I am driving about 8k per year, so there is no need to waste money on high end brand name tires which will crack and dry rot before wearing out!
