Pothole tire damage in Denver

A pothole does its damage in a fraction of a second, and most of what it breaks is invisible from the driver's seat. The tire that looks untouched at the kerb can be finished. The one with a gash across the tread can sometimes be saved. You cannot tell which is which by looking, and neither can anybody else.

Check these before you do anything else

Pull over somewhere safe and look at the wheel you hit on, then at the other three.

A bulge or a bubble in the sidewall. The belt inside has separated. C.R.S. 42-4-228(5)(c) lists any bump, bulge or knot affecting the tire structure among the conditions that make a tire unsafe in Colorado. It is a replacement.

A cut or a pinch line low on the sidewall. Same answer. Nothing in a sidewall is repairable under the US Tire Manufacturers Association standard, and Colorado's list also covers a break which exposes a tire body cord.

A bent or cracked wheel. Alloys crack rather than fold. A tire that starts losing air after an impact with no mark anywhere on it is very often the rim. Tire losing air with no nail in it covers the rest of the list.

Nothing visible, and the pressure falling. Impact damage hides inside the casing. Finding it means taking the tire off the wheel and inspecting the inner liner, which the repair standard requires before any repair anyway.

Why Denver breaks pavement the way it does

Denver is not a cold city. It is a city that cannot make up its mind, twice a day.

The NOAA 1991-2020 normals at Denver Central Park record 156.5 days a year with a low at or below 32 F, but only 21.0 days a year on which the temperature never rises above freezing. Subtract one from the other and you get roughly 136 days a year on which Denver crosses the freezing point in both directions. That is arithmetic on two published normals rather than a published cycle count, but the same arithmetic applied to Chicago gives about 79, so Denver runs roughly 1.7 times Chicago's exposure. The January normal high here is 44.5 F.

Water gets into pavement, freezes overnight, expands, thaws by lunchtime, and does it again tomorrow.

The season, from Denver's own 311 archive

We counted the city's five yearly 311 archive layers for 2019 to 2023: 28,091 street pothole requests and 2,273 alley pothole requests, 30,364 in total.

Ranked by month over those five years, March is the peak at 4,563 and November the trough at 1,108. February through May carries 13,343 requests, 47.5% of the year's street pothole complaints in four months.

March is also Denver's snowiest month, at 10.7 inches in the same NOAA normals, ahead of November at 8.7 and December at 8.5. The snow and the potholes arrive together, and both of them land after most people think winter has finished.

Ranked across all 11 Denver council districts, District 7 recorded the most street pothole complaints at 2,860 and District 11 the fewest at 964. District 11 also recorded not one alley pothole request in five years, which is what a part of the city built without an alley grid looks like in a complaint dataset.

These are complaints, not potholes, and they are not adjusted for population or road miles. They still tell you when the season is.

What the city does about it, and what the streets are like

Denver's own pothole repair log holds 9,363 repair tasks between December 2023 and 14 September 2026. Of the tasks carrying a response time, the median is 1.0 day, 74.4% were done within three days and 92.4% within seven. Repairs peak in April, a month after complaints do.

Denver DOTI also publishes an average pavement condition index by neighbourhood. Ranked over all 78, Highland at 65.4 and Cherry Creek at 66.0 are among the eight lowest, while the newer northeast is among the highest, with Central Park at 81.4 and Gateway and Green Valley Ranch at 80.9. That layer is a draft view with no survey date, so read it as a ranking, not a dated measurement.

Getting the car back on the road

We supply and fit replacement tires where the car is parked, so a car with a wrecked sidewall does not have to be driven anywhere first. The price is on screen in minutes, with no callback and no separate call-out fee. If the damage turns out to be a repairable tread puncture rather than a write-off, we repair it instead and say so, and if the tire is unrepairable the inspection is charged and the repair is not.

One Colorado point on replacement. There are two tread numbers in the statute book: the unsafe threshold of two thirty-seconds of an inch in 42-4-228(5)(c)(III), and the Traction Law standard of three sixteenths, which is six thirty-seconds, on I-70 between Dotsero and Morrison from 1 September to 31 May under 42-4-106. Buy against the one you actually drive on. Repair or replace a tire covers the decision, find your tire size covers what you are buying, what mobile tire replacement costs covers the number, and our Denver service area covers where we come.

Our price: $145

A mobile puncture repair on one tire is $145. That is a price, not a range and not a starting point. It buys the trip out, the wheel off, the tire off the rim, an inspection of the inner liner, a plug and patch fitted to the tire industry standard, remounting, rebalancing, a TPMS reset where supported, and the pressure set to the placard. Nothing is added afterwards for the call-out.

Questions people ask

• When is pothole season in Denver? February through May. Those four months carry 13,343 of the 28,091 street pothole requests made to Denver 311 between 2019 and 2023, 47.5% of the year, and March is the worst single month at 4,563.
• Why is Denver so hard on pavement when it is not that cold? Because it thaws. The NOAA normals give 156.5 nights a year at or below freezing but only 21.0 days that never climb above it, which leaves roughly 136 days a year crossing the freezing point in both directions.
• A bulge came up after I hit it. Can that be repaired? No. A bulge is a separated belt, it is not repairable under the tire industry standard, and C.R.S. 42-4-228(5)(c) lists a bump, bulge or knot affecting the tire structure as making a tire unsafe.
• The tire looks fine but keeps going down. Often the wheel rather than the tire. A cracked alloy leaks with nothing showing on the tread, and impact damage inside a casing needs the tire off the wheel to find.
• Do the alleys break up at the same time? No. Alley pothole requests to Denver 311 over 2019 to 2023 peak in August at 299 and bottom out in January at 93, which is close to the opposite of the street curve.
