A friend of mine is in a bit of a dilemma. The summer tires on his Toyota Corolla are somewhat worn. I had a look and two of them seemed to be 1/2 worn out. The other two were a bit worn, but not as badly. He wanted to know when he should get new ones. He doesn't know if he should get them now, or just try to make due with the ones he has on until winter when he'll change to brand new winter tires. With the weather being some of the strangest in Canada down here (NS) sometimes we think that winter may come sooner rather than later and he doesn't wanna get stuck buying new summers when he'll just have to change them back in a couple of months.
He could probably get away with the tires he has on, but in my opinion, I would just buy new ones and if winter comes early, then fine, it just means you've got new ones for next summer. But he isn't convinced. Any comments/Advice?
