Hey, I have made sure the tires and everything are all in check! I even just filled up with Nitrogen and it still had the flat spots! What can ya do? Thanks guys!

 

Have you tried 35 psi? Is flat-spottinga cold weather issue only? Unlike summer tires, A/S or winter tires should remain soft below 6' C. May be that's the problem.

 

I had them up to 37. It is just the way the tire is made, with the nylon I suppose...oh well!

 

37? Thats really high. Ive had 5 cars, all diffrent styles and sizes and none of them were ever that high. Who informed you that was the right psi? If its only word of mouth.. i would check online with the tire company and see if they recommend a lower psi. For smaller cars, i believe 28-32 is the norm. If your way over the normal limit of the tire.. youll make a bubble effect on the tire. Combined with the cold ( meaning bubble frozen on tire till warm ).. youll get wobble for sure.

Definetly check for that..

 

If they are stock tires on stock wheels the correct inflation pressure is on a tag inside the driver's side door. Other than that, you want to make sure you have a good even pressure map across the contact patch of the tire. A little dust on the ground and a nice clean tire to a good job of showing you where the tire contacts the ground.

I haven't had any flat-spotting/wear issues with my Toyo Proxes FZ4's even with a Prokit drop.

 

haha, no I dont use 37 psi all the time. I just tied it to see if it would get rid of the flat spots. Like I said I have the nitrogen in the tires now. But I appreciate all of your help!

 

Nitrogenwon't helpmuch sinceordinary air contains about80% nitrogen.
