Had the new KO2's installed today.
HOLY SHIT! I know my old tires were on their last legs with 114k on them. They wore evenly, had fine grip in the rain, and made it through the Chicago winter just fine.....but seriously. On a scale of 1-10, replacing the worn suspension improved the ride by like a 5 and the tires are a definitive 10. I was still disappointed with how my car handled after just the suspension replacement. It just felt like something was off. The ride was still quite jarring at times.
Immediately I noticed a difference, just pulling out of the parking lot. Unbelievably smooth, a quarter of the road noise, zero highway vibration, and a way more controlled ride. The ride actually drastically improved going from worn C rated tires to the E's. They also don't rub at all!
I'd be lying if I didn't feel a slight power decrease. Unsprung weight went from 45#/tire to 55#. Stock is 38#. It's not noticeable in city driving with the V8 torque.
Unbelievably happy!!! I know my alignment is close but I'm taking it to a fellow member and 4Runner buff to really dial it in.
Moral of the story: replace tires after 5 years regardless of mileage and tread wear.
Full size pic when I get my D800 out. No rubbing and no trimming.
