I'm sure if I keep up with the rotation and check tire pressure it should be fine.
My current Nokian WR tires have almost 108,000km (67,000 miles) on them, and I'm sure the same type will last while on the 5.
I wish our weather was like San Diego. That's a place with nice weather.
The cars here take a bit of beating with our extremes in temp. When its really cold, the tires feel like square blocks, and everything squeaks and groans. When it warms up, you feel like you have a new car.
LOL 67,000 miles. I have never, in my entire life, had a set of tires last more than 25,000 miles. Although in most cases, they were performance tires on performance cars so it makes sense.
