Tire damage or something else? Help with new Latitudes

[davidtobin]

I recently replaced the Toyo Proxes tires on my 2004 BMS X5 4.4. Sport Package vehicle with Michelin Latitudes. I then ran the vehicle into a curb, cosmetically damaging both wheels on the passenger side, and damaging the right front tire (it showed a bulge which suggested a damaged side wall). I replaced the right front tire, had the wheels repaired, and had a front and rear alignment done. The vehicle has lost the smooth ride (from rear) that it had when the new tires were installed. I feel like I'm running knobby snow tires on the back. I've had them rebalanced and tire pressure is the recommended 32psi. I don't believe the suspension was damaged when I hit the curb but there is no immediately visible damage. Could the rear tire have been damaged without showing it? Just because it balances doesn't mean the tire wasn't damaged internally which is causing the rough ride? Your thoughts welcomed.

i would check suspension,when you it curb and hard enough,it could easily damage control arm

check suspension, and also check where you got your tires installed if they used a roadforce balancer. if not, the more primitive balancing machines do not pick up vibrations with the vehicle weight.

I agree with the roadforce balancer check.

[davidtobin]

I have had the tires roadforce balanced and the suspension checked visually. I'm still getting a rough ride with these Latitude's. Not as bad siince I lowered air pressure to 32 but still too rough.

a quick check could be to swap the rear tires with the front to see if the problem persists. I would not take any hard corners, but from a simple ride evaluation this could help.

Rough ride meaning? Vibration? Harsh when you hit bumps? Noise?

[davidtobin]

no noise and no vibration par se. It's more feeling like a rough (small gravel) road sensation, like the tires are feeling every little imperfection in the road surface. fronts are at 32, rears 36.

[anerbe]

did you swap the rears with the fronts? another option is if your local independent shop has some wheels/tires you can put on it. you need to determine whether it's a wheel/tire issue or suspension issue.

since you didn't replace your rear tire after the hit, could be internal tire damage (belt shift) or something. try isolating what the issue is first and post your findings.
