Mobile tire service in North Chattanooga and the North Shore

ZCTA 37405 covers Frazier Avenue, Stuart Heights, Mountain Creek and the whole western flank running up Signal Mountain. At 54.33 square miles it is the largest of the fourteen Chattanooga-area ZCTAs our city research profiled (2024 Census Gazetteer) — larger than the entire land area of several of the others put together, and the reason a single answer about "the North Shore" is usually wrong.

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

One ZIP, 651 feet to 1,801 feet

USGS 3DEP one-metre point queries, all read 2026-09-20 at coordinates we chose:

• Frazier Avenue, on the North Shore: 651.7 feet
• This ZCTA's published Census internal point: 1,214 feet
• Signal Point, on Signal Mountain above the western flank: 1,801.1 feet
• Market Street at 8th, downtown, for reference: 676.5 feet

The internal point sits 518 feet above the downtown ZCTA's own internal point of 696 feet (derived: 1,214 minus 696, both USGS reads on 2026-09-20). Signal Point stands 1,124.6 feet above the Market Street reading (derived: 1,801.1 minus 676.5).

Every one of those is a single point at a single coordinate. None is a neighbourhood average, none is a summit elevation, and no pair of them is a gradient. We publish no percent grade for any Chattanooga street or neighbourhood, because the county's published slope polygons will not cut to that scale without overcounting, and an invented grade is worse than none.

What the spread does tell you honestly: an address on Frazier Avenue and an address up the Signal Mountain road are in the same ZIP and are not the same job. So we ask for the block, not the ZIP.

Signal Mountain is a different town

The town of Signal Mountain is separately incorporated: 8,860 people on ACS 2020–2024 estimates, 89.5% of its housing one-unit detached, 26.1% working at home, and a mean commute of 27.5 minutes — the price of living on top of the climb. If your address is in the town rather than in the City of Chattanooga, we still come; we simply name which municipality a fact covers, because in this metro that distinction changes what the city's own datasets can tell you. East Ridge is the sharpest example of why.

Two shops in this ZIP, $48.68 apart on the same job

Tire Rack's recommended-installer directory for this metro lists twelve shops and prices every one of them. Two of the twelve have 37405 addresses, and they do not agree with each other:

• Quality Tire, 322 Cherokee Blvd — $182.00 for the four-tire installation Tire Rack prices, 7 surveys.
• Tire World & Auto Service, 245 Signal Mountain Rd — $133.32, 8 surveys.

That is a gap of $48.68 (derived: 182.00 minus 133.32) on the identical quoted job, at two addresses in the same ZIP. The job is Tire Rack's default configuration, a 2020 Toyota RAV4 AWD LE on 225/65R17 Michelin CrossClimate2, read 2026-09-20; a different size moves both cards.

The line items explain it. Quality Tire charges $40.00 a tire to 20in, $45.00 at 21–22in, $50.00 at 23–30in, $60.00 at the odd sizes, plus $2.00 stems, $3.00 disposal and $40.00 package installation. Tire World charges $40.00 for 0–35 series but $20.00 for 40–45, 50–55 and 60-plus — the cheapest per-tire mount and balance of the twelve for an ordinary sidewall — with $5.00 stems, $3.33 disposal and $15.00 package installation. A low-profile wheel costs exactly twice as much to fit at Tire World as a crossover tire does.

Neither is a mobile installer. None of the twelve is. And Tire Rack's own ZIP lookup, called for 37405 on 2026-09-20, returned [{"mobileInstallerType":""}] — an empty string, no programme — where the same endpoint returns a programme name for Dallas 75206 and Atlanta 30306 the same day.

Who lives here, and where the car sits

18,109 residents in 8,620 occupied units, 48.7% owner-occupied and 51.3% renter, median unit in the 1980s build band. The housing is genuinely mixed for Chattanooga: 46.2% one-unit detached against 57.6% across the City of Chattanooga, 17.4% in buildings of five to nineteen units, 18.8% in buildings of twenty or more, and 2.6% mobile homes.

That mix is the practical point. Near Frazier Avenue a booking is often an apartment building and a kerb space; up Mountain Creek or towards Stuart Heights it is a house and a drive. We use the detached share only 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.

The requirement is the same at both ends: level, paved, legal ground with room to work at one corner of the car and room for the van. Tire Rack publishes the version its own vans work to — "a flat, paved surface with 6 feet of clearance around your vehicle ... A minimum of 10 feet of vertical clearance is also required" — and in a ZIP with this much slope in it, that is a question worth settling on the phone rather than at your kerb.

74.7% drive alone, 4.4% carpool, 0.5% take public transport, 1.7% walk or cycle and 18.1% work at home. 7.1% of households keep no vehicle, 41.6% one, 37.7% two and 13.6% three or more. Mean commute 17.7 minutes (derived: ACS table B08013 aggregate travel time over the workers in table B08301 less those who worked at home, on a base of 10,025).

Inside this ZCTA the City of Chattanooga's pothole feed recorded 1,417 service requests over the nine years 1 January 2015 to 31 December 2023, counted by spatial query against the city's own layer. Note what that count can and cannot cover: this ZCTA spills past the city line, and a request about a street the City of Chattanooga does not appear in this feed for will not be in it. The feed's last row is 6 October 2024, so nothing here is about this year.

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. If the only place to work is a pitched drive on the mountain road with no level ground in reach, we will say so before you pay.

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.

The $182.00 and $133.32 above are fixed-shop installation totals for tires bought from Tire Rack, on one specific vehicle and size. They are not mobile prices and they are not ours. No business operating in Chattanooga publishes a mobile tire price of any kind. What mobile replacement costs and mobile versus a tire shop set out the trade, and tire service on a steep driveway covers the mountain road end of this ZIP.

Questions people ask

• I am halfway up the mountain. Will you come? Yes, and the price is the same because there is no call-out fee. What we need is a level, paved spot at the address or close to it.
• Frazier Avenue, no driveway. A legal kerb space with room around the car works. Tell us at booking which side of the street.
• Two shops in my ZIP quote $48.68 apart. Why? Different line items: per-tire rate, disposal, stems and a package fee. Both totals are Tire Rack's own, for the same quoted vehicle, read 2026-09-20.
• Is the tire repairable? Only decidable with it off the rim: repair or replace a tire and plug versus patch.
• The car pulls and hums at speed after a pothole. Humming or roaring that changes with speed, and thumping noise from a tire.
• What pressure? The placard on the driver's door frame, read cold: the tire pressure placard.
• Nearby? Downtown across the river, Highland Park, Lookout Valley and Hamilton Place and East Brainerd.
