Ok well i got my tien h tech springs put on the other day and loved them ( and i put my progress sway on).. Well now i got my tires mounted on my 18's ive had for a few months.. But theres a problem now the place that put them on said it had a little warp to it and had up and down play when they spun them.. So i got them put on and now im having problems.. 1. Is at 70mph or higher the car feels real unstable and the front feels like it wants to move around and come off the ground.. 2. on hard braking and from like 75-90 the car steering wheel vibrates a little.. and 3. When i hit sharp turns real hard the front tire rubs and i almost wrecked a couple times,, it scared me lol... I dont know how to fix this and am getting real depressed cus i just dropped like 2,500$ on all this and its being crapppy.. And i dunno if i can get new rims since ive had them for a couple months and now have them on the car.. please help me guys... thanks peace

What size wheels? Did they balance the wheels/tires PROPERLY? Aftermarket wheels right? Did they give you hub rings with them?

THE SHADOW

I think they only did what's called a static balance on the tires. The balancing machines have a way to measure side to side AND up and down rotation. If they only measured the side to side, that's static. Dynamic balance is measure both side to side and up and down and correcting it. We did dynamic at BMW/Audi/Porsche all the time and had people that went to Sears (mainly place I know that does static balance) and had to get an entire new balance due to the same issue.


Really important note: B/c the G-forces are directional, make sure they put them on in the right direction. There's an arrow on the side of the tire that says "Rotation" and points one way.

Those tires are Y rated (up to 186 mph) so they should be much more stable than stock at those higher speeds. Mine are so I can tell you it's not the tires, unless you have a bad tire(s) that was sent to you.
