Hankook Tire Noise!

Cracked 4K miles, and the tire sounds louder and louder cruising around! It reminds me of off-road tire noise from a Jeep I used to have it sounds like “woo woo woo” aka uneven tread.

Anyone else hearing it? And another thing I noticed is the tire pressure keeps building up from recommended even though it’s been cold? Could it be cause of the tire pressure?

Took the car from the dealer brand new with 50psi tire pressure, didnt notice it at that time I was so happy with the car but the ride quality was abit harsh (still much better than F90). Adjusted the pressure and Im very happy. I cant tell you about the tires as Im still at 1300miles but it stays around 35 psi.

How are y’all’s tires wearing? Someone had posted that their tires were around 3 by 4k miles. I know they start around 7.5, but I was worried these things won’t make it 10k. I would hate to replace them 3 times before the lease is up lol.

I like the firmness but not when the tires rubber starts to feel like it’s frozen hard

What is the recommended pressure? On my F90 I think it was recommended 36 if you go over 100 mph, and thats what I ran. Seems like 41 seems quite high, and perhaps that can be factor in this.

It’s 35. I hope it solves the problem.
