Mobile tire service in Highland Park, Chattanooga

Highland Park is the one Chattanooga neighbourhood in our set where the car is least often driven alone. 60.5% drive alone to work, the lowest of the fourteen Chattanooga-area ZCTAs our city research profiled, and 17.4% carpool, the highest of those fourteen. Across the city the drive-alone figure is 73.6% and the carpool figure is 8.8%.

That carpool spread is the interesting part. Drive-alone across the fourteen runs from 60.5% here to 81.0% in Lookout Valley, a range of about twenty points. Carpool runs from 0.1% downtown to 17.4% here, which is a much wider relative spread. A carpooled car is a car that two households are counting on.

We supply the tires and fit them where the car is parked, here and across the Chattanooga metro. No separate call-out fee.

Missionary Ridge is not a mountain

Highland Park's pre-war bungalow grid runs east from downtown to the foot of Missionary Ridge, and the name does a lot of work in people's heads. So here is the measurement.

USGS 3DEP one-metre point queries, read 2026-09-20, at coordinates we chose: Market Street at 8th downtown reads 676.5 feet. Crest Road on Missionary Ridge, at the Sherman Reservation, reads 750.0 feet. That is a rise of 73.5 feet (derived: 750.0 minus 676.5).

Seventy-three and a half feet. For scale, Point Park on Lookout Mountain reads 2,037.0 feet at the point we sampled and Signal Point on Signal Mountain reads 1,801.1. The ridge that runs through Chattanooga's eastern neighbourhoods is a low ridge, and the mountains are somewhere else. If you have been told your block is unreachable because of the ridge, that is not what the elevation data says.

These are single point queries at named coordinates, not summit elevations and not averages, and two of them do not make a gradient. We do not publish a grade figure for any Chattanooga street, because the public slope data will not support one at that scale.

When Chattanooga's roads break, measured

This is the page to read about seasonality, because Highland Park's housing is old enough and its streets flat enough that what happens here is what happens to the asphalt.

The 311 count. Pothole service requests to the City of Chattanooga, summed over the nine full years 2015 to 2023, 17,430 requests in total, by month:

	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
Requests	1,489	2,010	2,229	1,783	1,551	1,500	1,423	1,335	1,096	1,075	812	1,127

March is the peak and November the trough. March runs 2.74 times November (derived: 2,229 divided by 812, same series, same nine years). January through March carries 5,728 requests, 32.9% of the year in a quarter of it (derived).

The freeze-thaw count. At Chattanooga Lovell Field, counting days in the daily record where the minimum fell below 32F and the maximum rose above 32F — one full crossing in one day — the thirty years 1996 to 2025 give a mean of 46.1 such days a year, a median of 49.5, and a range from 28 (in both 2019 and 2020) to 68 (1996). By month over those thirty years, out of 1,382 crossing days: January 449, December 371, February 288, November 143, March 117, April 7, October 7, and none at all from May through September. December, January and February alone carry 1,108 of the 1,382, which is 80.2% (derived).

That definition is ours — one calendar day with a low below freezing and a high above it — computed from the complete station record. It is not a published index and it is not comparable with a crossing count derived any other way, in this city or another one, so we do not rank Chattanooga against anywhere on it and neither should anyone else.

What we will not tell you is that one of those tables causes the other. The freeze-thaw window closes in March and the complaint peak is March, and that is where our evidence stops. We read no City of Chattanooga, TDOT or academic source stating the mechanism, and reporting behaviour, crew scheduling and the paving calendar could all be in it. Two measured seasons that line up is a useful thing to know in February. It is not a proof.

The feed's last row is 6 October 2024. There is no 2025 or 2026 Chattanooga pothole data in it and we found none elsewhere, so nothing on this page describes this year.

Asphalt, and how much of it is in poor condition

Chattanooga publishes a pavement condition index for its whole network, which several cities we work in do not. Querying the city's own layer on 2026-09-20: 9,065 street sections, 2,188.9 miles, mean PCI 61.45 on a 0–100 scale. By band, in miles: 411.0 miles at PCI 40 or below across 1,677 sections, 376.5 miles at 40–55, 590.2 at 55–70, 559.8 at 70–85 and 251.4 above 85. 411.0 of 2,188.9 miles is 18.8% of the network at PCI 40 or below (derived). At PCI 25 or below there are 496 sections and 119.7 miles, 5.5% (derived).

By surface, 2,110.1 of those 2,188.9 miles are asphalt concrete — 96.4% of the network (derived) — and the city still carries 2.2 miles of gravel street, which scores a mean PCI of 13.9, the lowest-scoring surface class in the layer.

Two honest caveats. The layer is named PCI2020 and neither the service nor its catalogue entry states a survey date, so read it as the city's published pavement index and not as this morning's condition. And the 2,188.9 miles is our sum over every section in that layer, not a network length the city publishes. There is also no per-ZIP pavement figure in it that we ran, so we have no PCI number for Highland Park specifically and will not derive one from council districts, which do not nest inside ZIPs.

Inside this ZCTA the pothole feed recorded 1,606 service requests over those same nine years, 2015 to 2023, counted by spatial query. Take it as a count over that period and that channel, and nothing more.

A 1940s grid, and where the van goes

14,737 residents in 5,057 occupied units across 5.18 square miles (2024 Census Gazetteer), 50.0% owner-occupied and 50.0% renter. The median unit falls in the 1940s build band, joint oldest of the fourteen ZCTAs profiled, tied with St Elmo. 73.7% of units are one-unit detached against 57.6% across the City of Chattanooga, and 15.6% sit in 2-to-4 unit buildings.

We use that detached share as a proxy for off-street space and label it as one, because the American Community Survey carries no garage or driveway variable and Chattanooga publishes no garage count. A pre-war bungalow grid tends to mean a narrow strip drive or a kerb space, and either works: we need level, paved, legal ground with room to work at one corner of the car and room for the van.

For a sense of the bar other operators publish, Tire Rack states its own: "a flat, paved surface with 6 feet of clearance around your vehicle ... A minimum of 10 feet of vertical clearance is also required." A single-file 1940s drive with a fence one side often fails the six feet. The street in front of the house usually does not.

8.6% of households here keep no vehicle, 35.0% keep one, 34.4% two and 22.0% three or more. Mean commute 16.7 minutes (derived: ACS table B08013 aggregate travel time over the workers in table B08301 less those who worked at home, on a base of 6,706). Ground elevation at the ZCTA's published Census internal point is 682 feet — one published point, not a neighbourhood average.

What we do not do

We supply the tires we fit, so a set bought elsewhere is out. No alignment, no rotation on its own, no balancing on its own, no brakes, no emergency roadside. Mobile puncture repair is in scope, subject to inspecting the tire from the inside once it is off the rim.

Our price: $145, and $50 for each extra tire

A mobile puncture repair is $145 for the first tire and $50 for each additional tire in the same visit. That is the price, not an estimate and not a starting figure. It covers getting to you, the wheel off, the tire demounted and inspected from the inside, a plug and patch fitted the way the tire industry requires, remounting, rebalancing, a TPMS reset where the vehicle supports it, and the wheel back on. There is no separate call-out fee. If the damage turns out not to be repairable, we tell you on the spot: the inspection is charged and the repair is not.

An impact is the case where the answer is most often no. A bulge in the sidewall after a hole is a replacement, never a repair, whoever you ask. What tire repair costs sets out how the number is built, and tire repair cost in Chattanooga collects the local published figures.

Questions people ask

• When is the worst time of year for this? On the city's own nine-year record, March, with February close behind and November the quietest month by some distance.
• I hit something and the wheel now thumps. Thumping noise from a tire, and if there is a swelling in the sidewall, a bulge in the sidewall — that one is not repairable.
• Slow leak with no nail in sight? Common after an impact: a tire losing air with no nail.
• Is Missionary Ridge too steep for a van? The point we sampled on Crest Road stands 73.5 feet above downtown. The answer is about your specific kerb, not about the ridge.
• We carpool and the car has to be out at seven. Tell us at booking. Fitting at the address is exactly the case this is for.
• What pressure should it be at? The placard on the driver's door frame, read cold: the tire pressure placard.
• Nearby? Downtown, East Lake, East Ridge and Hamilton Place and East Brainerd.
