I had a set of Firestones on my 31 Tudor 450/500 19s. They were just worn out. So this year I did my research and decided to purchase 5 new 450/500 19s American classics radials. With the old tires the car handled great ! It stopped it didn’t pull and it didn’t sway at all. Now it’s like a different car. After I installed the tires I did a front end alignment and checked for any type of play. The king pins about 2 ths play that’s it. I set the tire pressure to 30lbs. Off for a test drive
Now there’s a sway that is Terrible.
I changed the tire pressure to 45lbs with no improvement. I can shake the car and you can see the side walls flexing
the car ran fine before the tire change
Has anyone else have this problem?
