Direct answer: If your driveway is sinking by one tire track, the usual cause is not the top surface by itself. Most of the time the base under that wheel path has lost support from poor compaction, water washout, or repeated heavy loading in the same line.
Most likely: A narrow rut that follows the same wheel path usually means the base under that strip has settled. If the area stays soft after rain, water is likely part of the problem.
Start by figuring out whether you have a shallow surface depression, a soft failing section, or a larger drainage problem washing out the base. Reality check: a true tire-track sink almost always comes back if the water or base problem stays in place. Common wrong move: adding more patch to a soft spot year after year without fixing where the support disappeared.
Don’t start with: Do not start by smearing sealer or filler over the low spot. That hides the shape for a while but does not rebuild support underneath.
The tire path is lower than the surrounding driveway, but it feels firm underfoot and does not flex or crumble.
Start here: Check drainage and measure how deep the dip is. This is the best case for a limited surface repair.
The area feels weak, stays damp, or shifts slightly when driven over.
Start here: Assume the base has lost support until proven otherwise. Look for water coming from gutters, downspouts, or the driveway edge.
The low tire track also has alligator cracking, broken edges, or loose aggregate.
Start here: Treat this as structural failure of the driveway section, not just a low spot.
The rut runs close to the driveway edge, shoulder, or side yard and the edge may be breaking away.
Start here: Look for edge washout, poor side support, or runoff cutting away the base from the side.
A rut that follows the same vehicle line with otherwise intact surface usually means the base settled where the load repeats every day.
Quick check: Lay a straight board across the low area. If the dip is narrow and the surrounding surface is still solid, settlement below the surface is likely.
If the low track gets worse after storms or stays damp longer than the rest, water is probably moving under or beside that section.
Quick check: Look for downspouts, sprinkler overspray, roof runoff, standing water, or a low shoulder next to the rut.
One tire track near the edge often sinks because the side support is gone and the wheel load pushes the section outward and down.
Quick check: Inspect the driveway edge for crumbling, a drop-off into soil, or a gap where the side has eroded away.
If delivery trucks, trailers, or heavy vehicles use the same line, asphalt especially can rut or crack even when the rest looks acceptable.
Quick check: Think about what parks there and when the problem started. If it lines up with heavier use, loading is part of the story.
You need to know whether this is a shallow low spot, a soft section, or a failing edge. Those repairs are not the same.
Next move: If the depression is shallow, dry, and firm with no major cracking, you may be able to correct the surface after you address drainage. If the area feels soft, breaks apart, or drops toward the edge, stop thinking cosmetic repair and move to support and drainage checks.
What to conclude: A firm low spot can sometimes be patched. A soft or broken one usually means the base underneath is failing.
Water is the most common reason a settled wheel path keeps getting worse after you patch it.
Next move: If you find a clear water source, correct that first or any surface repair will be short-lived. If the area stays dry and there is no sign of washout, repeated loading or original base compaction is more likely.
What to conclude: A driveway rarely sinks in one wheel path for no reason. Water usually explains why one strip lost support while the rest stayed put.
This is where you decide whether a simple patch material has a fair chance or whether the section needs rebuilding.
Next move: If it is truly a stable low spot, a driveway patch material can restore the surface profile after drainage is corrected. If the section is failing, skip patch-only thinking and plan for professional lifting, base repair, or partial replacement.
The right fix depends on whether the driveway surface is still supported.
Next move: A proper surface correction should leave the wheel path even, drain water off, and stay firm under traffic. If the patch sinks again, cracks quickly, or traps water, the support problem underneath was not solved.
One tire-track sink can stay small for a while, but once the base starts moving it usually spreads under traffic and weather.
A good result: If the area stays level and drains cleanly, keep monitoring and avoid heavy repeated loading in the same line.
If not: If movement continues, the lasting fix is usually base repair or section replacement, not more topping.
What to conclude: Stable after rain and traffic means you likely caught it early. Continued movement means the support below is still failing.

Only if the driveway surface is still solid underneath. If the area is soft, wet, or cracking badly, filler or patch will usually sink again because the support below is still missing.
That usually happens where vehicles load the same narrow strip over and over. If that strip had weaker compaction or got wet from runoff, it settles first while the rest still looks fine.
Both can do it, but it shows up differently. Asphalt often ruts, softens, or cracks in the wheel path. Concrete more often settles as a slab section, drops at an edge, or develops a void underneath.
Look for a rut that worsens after storms, stays damp longer than nearby pavement, holds water, or sits near a downspout, low shoulder, or erosion channel. Those are strong field clues that water is washing out support.
Call when the area is soft, the edge is failing, the rut is deep, cracks are spreading, or the low track comes back after a patch. At that point the lasting repair usually involves rebuilding support, not just restoring the surface.
