Illinois State Police said they have not determined how the tire came off the SUV. The case remains under investigation.
The person hurt in the Porsche was taken to a hospital with injuries described as minor. No other injuries were reported.

Why Tires Separate From Vehicles on Highways Like the Edens Expressway
A wheel does not usually come off a moving vehicle without warning. It is often the end point of a problem that built up over weeks: a lug nut loosened after a tire change and never retorqued, a wheel bearing worn past its limit, or a tire that was underinflated or already separating at the belt before it ever reached highway speed. At 60 or 70 mph, a failure that would be a minor nuisance in a parking lot becomes a projectile.
Road and weather conditions matter even when the tire itself is the problem. Wet pavement or debris in a travel lane can make a driver swerve or brake hard right as a wheel is failing, adding stress to an already weakened connection. Once a tire separates, it can bounce, roll, or go airborne depending on speed and the angle it departs the vehicle, and on a divided highway like the Edens Expressway there is little keeping it from crossing into opposing lanes.
Stopping distance plays a role for the drivers who encounter the hazard, too. A dry road gives a following driver more room to react and swerve around debris; wet or icy pavement cuts that margin and can turn an evasive move into a second crash. Investigators looking at these incidents typically check tire maintenance records, lug torque, and wheel bearing condition to figure out why the separation happened in the first place.
Frequently Asked Questions
What should I do if I see a tire or other debris in the road ahead?
Slow down gradually, check mirrors, and change lanes only when it's safe. Sudden braking or swerving in reaction to debris causes many of the secondary crashes linked to road hazards.
What are common injuries when debris strikes a windshield?
Glass fragments, facial cuts, and head or neck injuries from sudden braking or impact are typical. Anyone involved should be checked by a medical provider even if injuries initially seem minor.
How does driving speed affect the outcome of a crash like this?
Higher speed means less time to react and more force on impact. The same tire separation that causes minor damage at low speed can shatter a windshield or cause a serious injury at highway speed.
What usually causes a tire to come off a vehicle while driving?
Loose or improperly torqued lug nuts, worn wheel bearings, and tire or rim damage are the most common culprits. Routine maintenance checks catch most of these before they become a safety risk.
What to Do After a Tire Separation Crash in Wilmette, IL
If a tire or road debris strikes your vehicle, pull over safely once possible and call 911 to report the crash and request medical evaluation. Even injuries that feel minor, such as cuts from broken glass or soreness from a startled reaction, are worth having checked by a doctor the same day.
Take photos of the vehicle damage and the scene if it's safe to do so, and get the names of any responding officers or agencies. If you're a passenger or witness, note the time and location as closely as you can, since that information helps investigators piece together how the failure happened.
Keep any paperwork from the responding fire department or state police, and follow up with your insurer promptly. If the other vehicle's owner or a maintenance shop may bear responsibility for the tire's condition, documentation gathered soon after the crash tends to matter most.
