2 Front tires rattling?

[18tboost]

I just picked up a set of HRE's 545R with 85% Yokos, but the two front are roaring when i go starting from 20KM, what is wrong? some say i can solve this problem by switching them to the back, need ur advise...

the tires are probably just noisy, you can try moving the rears to the front, but its probably just hard rubber that is noisy on the road.

Either that or the front tires are worn unevenly (from a bad alignment & balance on the previous owner's car). The roar is not likely to go away, so, your best bet is to replace the tires and get a fresh alignment for your car.

You can tell if the tires are worn or "chopped" by running the palm of your hand on the tread of the tire. If it's smooth (even w/ the tread pattern), then the tire is just a noisy tire. If you feel an uneven edge as you move along the tread (like knife blades), then the tire is "chopped" and will need to be replaced for a quiet ride. Usually the chopping will take place on the inside edge.
