Mobile tire service in Barber Valley, Boise

Boise has no annual inspection and no emissions test, so there are only two dates in the year that force a decision about your tires, and both of them are set by one sentence of Idaho Code. Studded tires are prohibited on public highways between 1 May and 30 September, which makes the lawful window 1 October to 30 April. That is the statute's own arithmetic: it writes the closed season, and the open season is what is left.

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

The law opens about a month before the weather, and closes about a month after it

This is the part worth planning around, and both halves of it are measured.

The window opens on 1 October. NOAA's 1991–2020 normals at Boise Air Terminal give October 3.3 nights at or below freezing and 0.1 inch of snow. The first month that behaves like winter is November, with 14.2 freezing nights and 2.6 inches, and the peak is December and January at 24.9 and 23.9 freezing nights and 7.0 and 5.1 inches of snow. At the far end, April carries 4.5 freezing nights and 0.3 inches while the window still runs to the 30th.

So a driver who studs up on the day the law allows it spends most of October running metal on dry pavement, and a driver who waits until the last legal day in April has had winter tires on through a month that barely freezes. The dates are legal boundaries, not weather forecasts. If you want the swap to track the weather rather than the statute, the first week of November and the first half of April are where the normals actually turn.

Note one thing the statute does that most people miss: in Idaho a snow tire and a studded tire are different categories in law. Idaho Code 49-121(2) defines a snow tire as one with tread design or embedded material to improve winter traction "except studded tires". Only the studded category has a closed season. A studless winter tire is untouched by the May-to-September prohibition, which is worth knowing if you want winter grip and do not want a date on the calendar.

What the stud rules bind, and who they bind

There is a second part of the same section, 49-948(4), that sets stud weight and protrusion limits: studs may not protrude more than six-hundredths of an inch from the tread surface when originally installed, and may weigh no more than 1.5 grams at stud size 14 or less, 2.3 grams at size 15 or 16, and 3 grams at size 17 or larger.

Those sentences bind sellers and fitters, not drivers. The subject of every one of them is a commercial tire retailer or a tire shop and the verbs are "sell" and "manually install". Nothing in that subsection makes it an offence for a driver to run a tire whose studs exceed the limits. If anyone tells you it is illegal in Idaho to drive on studs over 1.5 grams, they have read the wrong half of the section. The half that binds you is the seasonal one; the half that binds a fitting business like ours is the weight and protrusion one.

Running studs in July is, in Idaho's classification, an infraction rather than a misdemeanour, because section 49-948 sits in chapter 9 of Title 49. We are not going to put a dollar figure on it: Idaho's fixed infraction penalties are set by court rule and we did not read it.

And while we are clearing out things people arrive believing: there is no Boise chain law. The chain-up requirement in the same statute applies by its own text to commercial vehicles on three northern Idaho passes — Lookout Pass and Fourth of July Pass on Interstate 90 and Lolo Pass on State Highway 12. For everyone else Idaho simply permits chains. Nothing requires them on a Boise street.

Of the ten metros we work in, only Idaho and Pennsylvania set dated studded-tire windows at all, and Idaho's is the longer by 46 days (derived: it opens 31 days earlier on 1 October against 1 November, and closes 15 days later on 30 April against 15 April). Idaho's studded tire window is the full version, month by month.

We do the swap at the house, and we are honest about what we will not do

Seasonal changeover is $350 for a set already mounted on its own wheels and $390 for loose tires that have to go onto the same wheels and be balanced. One visit, wheels off, balanced where the tires come off the rims, torqued to the manufacturer's figure, TPMS reset or relearned where the vehicle supports it. The car does not move.

We do not store your off-season set. Storage needs a building, a rate and insurance terms we do not have, and we are not going to pretend otherwise: the other set stays with you. What tire storage costs and what we do instead is the long version, seasonal tire changeover covers the job itself, and the winter changeover in Boise covers the local timing.

When the snow does come, your street is last

ACHD, which owns every street in Ada County, clears to a published priority order. Priority one is arterials and collectors, major intersections, overpasses and bridges, hospital and fire-station areas, school and railroad crossings, and streets with grades over six percent. Priority two is school bus routes. Priority three is "residential streets, including cul-de-sacs".

Boise's winter problem is not depth — 19.2 inches a year across 19.4 days with measurable snow — it is the handful of days when the last street to be cleared is the one your car is parked on. ACHD's materials are magnesium chloride, salt and sand. What those do to a wheel finish or a sensor over years we have no source for, so we are not going to claim anything about it.

The newest housing in Boise, and what that does not prove

This is the newest ZIP of the ten Boise-area ZIP codes in our research: the median unit falls in the 2000s build band, only 10.3% of units predate 1980, and 30.5% were built in the 2010s. 21,402 residents across 8,502 occupied housing units, 78.8% owner-occupied. 79.7% are one-unit detached, which we use as a labelled proxy for off-street space and nothing more.

We are not going to turn new houses into new cars. Housing age is not fleet age, no Idaho vehicle-registration statistics were pulled for this page, and the leap from one to the other is exactly the kind of invention we gate against. If your car is old enough to have no TPMS at all, tell us at booking and it changes nothing about the price.

What the census does say about cars here is striking on its own: 2.2% of households keep no vehicle, the lowest carless share of the ten, with 45.3% keeping two and 26.4% three or more. 69.4% drive alone, 20.5% work at home — the second highest of the ten, behind the North End's 24.4% — and the mean commute is 23.0 minutes (derived from ACS table B08013).

Geographically this ZIP does both halves of Boise at once. It runs along the river at Barber Valley and climbs into the foothills east of the city, and the overlay shows it: 998 of 11,065 addresses, 9.0%, fall inside the City of Boise Hillside designation, fourth of the ten and almost level with 83703's 9.3%. That is a planning overlay and not a gradient — the East End and Warm Springs Mesa page explains what it does and does not measure. 10,538 addresses, 95.2%, sit inside a registered association: Southeast Boise 5,906, Barber Valley 4,258 and South Eisenman 374.

What we do not do

We supply the tires we fit; customer-supplied fitting was withdrawn on 2026-09-20. No alignment, no rotation on its own, no balancing on its own, no brakes, no emergency roadside. We do not store tires. Mobile puncture repair is in scope, subject to inspecting the tire from the inside once it is off the rim. We need level, paved, legal ground with room to work at one corner of the car.

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. Fixed, 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. No separate call-out fee. If the damage is not repairable we say so on the spot: the inspection is charged and the repair is not.

Questions people ask

• When exactly must the studs come off? They are prohibited from 1 May. The last lawful day is 30 April.
• Can I run studs all year if they retract? The statute allows retractable studs year-round only where they retract to or below the wear bar and protrude only between 1 October and 30 April.
• Do I need chains for a Boise winter? No. Idaho's chain requirement covers commercial vehicles on three northern passes. Chains are merely permitted elsewhere.
• Studded or studless? All-season, all-weather and winter tires sets out the difference. In Idaho law only the studded kind has a closed season.
• Will you store the summer set? No. That is the half of the problem we cannot take away: tire storage.
• Do the same tires go back on the same wheels? For a $350 changeover yes, they are already on them. At $390 we mount loose tires on the wheels you have and balance them.
• Is there a reason to change before the deadline? What the studded season actually looks like against the weather, and mobile tire repair in Boise for the visit itself.
• Where else do you work in Boise? Southwest Boise, the East End and Warm Springs Mesa, the Lusk District, West Boise and Vista.
