It improve a bit after I lower the psi. I switch back to AP2 wheel and everything is back to normal. And summer tire feel so so much better than the cheap korean winter tire, lol. I hope it's the balance of the wheel, I don't want to see bent rims. t, I'll probably get the wheels balance and check to see any bents.


hx for all advices!

 

i would almost guarantee that they're out of balance. Take it to a shop for balancing, they can also tell you if you have a bent wheel

edit*
it doesn't matter that they were previously balanced, a weight could have fallen off or the place that balanced it wasn't calibrated correctly. I bought 4 new tires for my Jeep Cherokee at Sams Club and that thing shook like hell afterwards. I took it back FOUR times, each time they "re-balanced" the wheels, finally ended up telling me that I must have a bent wheel. I took it to my trusted neighborhood garage and had them look at it. All the wheels were straight but "they where so far out of balance it was ridiculous" is what they told me. Needless to say, Sams Club paid the garage's bill and I will never buy tires there again.

Good luck with your car, be careful and sorry for the novel.
