The classic epoxy horror story: perfect floor in spring, tire-shaped bald spots by August. Here's the chemistry behind hot tire pickup, why it's almost always preventable, and what to do if it already happened.
Hot tire pickup is exactly what it sounds like: you drive in on a hot day, park, and later find the coating stuck to your tires instead of your floor — leaving bare-concrete patches in the shape of your tire contact patches. The rest of the floor looks flawless, which is what makes it so maddening. It almost always appears in the floor's first summer, because that's the first time the coating meets truly hot tires.
It has a close cousin worth distinguishing: tire marking, where tires leave dark rubber marks on the coating without removing it. Marking is cosmetic and common; pickup is a bond failure. This article is about pickup — the one that takes the floor with it.
Three things conspire:
That third point is why professionals are blunt about hot tire pickup: it's not really a tire problem. It's a bond problem that tires reveal. A floor that loses coating to tires was a floor that was going to fail — the tires just found it first.
Notice the pattern: every cause is a shortcut. Hot tire pickup is the tax on rushed or cheap work.
Yes, measurably. Salt Lake Valley summers regularly push past 95°F, and a closed garage with afternoon sun on the door can sit 15–20 degrees hotter than outside air. Tires arriving off I-15 at 4 PM in July are at their softest and stickiest of the year. That doesn't mean Utah garages can't have epoxy — thousands do, happily — it means the cure schedule and the prep quality matter more here than in milder climates. If your installer waves off cure times because "it's warm out, it'll cure fast" — warmth accelerates cure, but vehicle loading still waits for the full schedule.

Get a written cure schedule and a prep scope that includes diamond grinding. That's 90% of hot tire pickup prevention.
First, don't panic — and don't keep parking on it, which spreads the damage. Small, isolated patches can be spot-repaired: the damaged area gets feathered back to sound coating, the exposed concrete re-prepped, and matching material patched in. Our repair guide walks through it.
But be honest about the pattern: if all four tire positions are failing, the bond is suspect across the whole floor, and spot repairs will chase failures for years. The right fix is usually a full recoat — grind everything off, prep properly, and start over. Painful, but it's the only fix that lasts. And check your warranty: adhesion failures in the first years are exactly what a good warranty covers, provided you followed the cure schedule.
Patches of coating missing exactly where the tires sit — often with the tire-tread pattern visible in the damage. The rest of the floor can look perfect. It usually shows up after the first hot summer of the floor's life, which is why it surprises people months after a seemingly fine install.
It's rare with a proper install: diamond-ground prep, high-solids epoxy, full cure before parking, and a quality topcoat. When pros' floors fail this way, the usual culprit is the car going back in too soon — before the coating fully cured. Follow the installer's cure schedule, not your impatience.
Yes — Salt Lake Valley summer highs regularly top 95°F, and a closed garage with sun on the door bakes well past that. Hotter tires are softer and stickier, and heat accelerates the plasticizer migration that causes the bond. Utah's climate makes proper cure time more important here, not less.
Follow your installer's specific schedule — it varies by product and temperature. As a rule of thumb, light foot traffic in 24 hours and vehicle traffic in 3–7 days for epoxy; polyaspartic is often ready for vehicles in about 24 hours. Parking early is the single most common cause of hot tire pickup on pro jobs. Timeline details: installation timeline.
They help — mats or containment trays under the tires keep hot rubber off the coating during the highest-risk period. They're a reasonable belt-and-suspenders move for the first summer on a new floor, though a properly installed and fully cured floor shouldn't need them permanently.
Usually, yes. Small areas get spot-repaired: feather the edges, re-prep the bare concrete, and patch with matching material. Widespread pickup across all four tire positions often means the bond is suspect everywhere, and a full recoat after proper grinding is the honest fix. See how to repair an epoxy floor.
Sometimes — it depends on the warranty's fine print. Good warranties cover adhesion failures; some exclude tire pickup explicitly or tie coverage to following the cure schedule. This is exactly the kind of clause to read before you sign. Our warranty guide shows what to look for.
