UK Tyre Price & Fitment Monitor — The Whole Shelf, By Size (2026)

One request returns the entire priced shelf for a tyre fitment size: every brand and pattern on offer with its fitted price and mail-order price, the fitting premium between them, EU label grades, exterior noise, season, runflat flag, load index, speed rating, shelf position and the earliest fitting date advertised.

Turn on delta mode and a daily schedule returns only the lines that moved — which is what a repricing desk actually reads.

No login. No API key. No browser. Clean JSON / CSV / Excel, billed per row you receive.

How to use it

1. Find your sizes. Mode size_index returns all 782 fitment sizes the retailer catalogues.
2. Sweep the ones you sell. Mode size_sweep with 205/55R16, 195/65R15, … — any common notation works (205-55-16, 205 55 16).
3. Schedule it with deltaMode: true and you get a movement feed instead of last night's shelf again.

What a row gives you

Field	Why it matters
fittedPrice / mailOrderPrice / fittingPremium	Both published prices and the gap between them — the fitting premium is the number UK buyers compare and almost nobody publishes as a field
brand, pattern, season	Kumho / Ecowing ES31 / Summer — the line identity, not just a product title
euFuelGrade, euWetGripGrade, noiseDb, noiseClass	The EU label, parsed out of the page rather than left as an image
runflat, loadIndex, speedRating	The spec attributes that decide whether a tyre is even a substitute
shelfPosition	Where the line sits on the shelf — visibility, not just price
earliestFittingDate	The soonest fitting slot advertised for that tyre
promotion	The multi-buy offer attached to the line

Delta mode — bills for movement, not for re-reading

changeType	Meaning
price_up / price_down	Fitted price moved, with priceChange and priceChangePct
promo_change	The multi-buy promotion on the line changed
rank_change	Shelf position moved by three slots or more, with positionChange
new	Line appeared on this size's shelf
withdrawn	Line was on this shelf and is gone from a size this run swept

Every change carries its previous values, so a row explains itself without a join. Unchanged lines are not returned and not charged, and a baseline run is billed at the ordinary row rate — starting a monitor should not cost more than running it.

Who this is for

Buyer	Job
Independent fitters and tyre chains	Reprice your core sizes against the market leader's actual fitted price, daily, without checking by hand
Tyre brands and importers	Where your patterns sit on the shelf, at what price, against which competitor, and when a rival discounts
Mobile fitting and fleet services	The fitted-vs-mail-order gap by size — that spread is the whole business case for mobile fitting
Retail and automotive analysts	Seasonal price movement and label-grade mix as a consumer-spend read
Comparison and content sites	A clean spec-plus-price feed with EU label data already parsed

Sizing your run

Rows = sizes × postcodes, one request each, roughly 20-25 distinct tyres per shelf.

Setup	Requests	Rows	At $0.005/row
5 core sizes, one-off	5	~110	$0.55
40 sizes, daily snapshot	40/day	~900/day	$4.50/day
40 sizes, daily with delta	40/day	only the movers	typically a small fraction
Full catalogue sweep (782 sizes)	782	~17,000	$85

A run is capped at 1,200 requests so a typo cannot launch a runaway sweep.

Pricing

Event	Price	What it is
tyre-price-row	$0.005	One tyre on one size's shelf, full spec and both prices
price-change	$0.012	One line that moved in delta mode, with its previous values
size-record	$0.001	One fitment size from the catalogue index

Shelves that fail to fetch are pushed as error records with the reason and are never charged.

Limitations, stated plainly

• This is one UK retailer's shelf, done properly — not a multi-retailer index. It is the market leader's online fitted-price shelf, which is what most UK repricing is benchmarked against, but it is one source and the retailer field says so on every row.
• Postcodes do not change the fitting date. Tested rather than assumed: London (SW1A1AA) and Edinburgh (EH11AA) returned identical dates. The postcode input exists to reproduce what a customer in an area is quoted; it is not sold as a per-area availability signal.
• Promoted tyres are listed twice by the source — the same SKU in the highlighted strip and in the main list, identical except position. They are collapsed to one row, so you are never billed twice for one tyre.
• Paging parameters are ignored by the site. Coverage scales by size, not by paging, and this Actor does not pretend otherwise.
• No history before your first run. Prices cannot be backfilled by anyone.
• If the retailer ever refuses a run (403/429), the run fails loudly with that reason and charges nothing for the refused shelves. A GB datacenter proxy group is the fix; residential is not required.

FAQ

Do I need a proxy? Not from a normal IP — verified with no challenge and no rate limiting. See the note above for the 403 case.

Why are there ~21 tyres per size and not 200? That is the shelf the retailer actually shows for a fitment. Coverage grows by adding sizes, which is how the pricing scales too.

Can I get winter and all-season? They are on the same shelf; filter on season.

Why is my first delta run large? It is the baseline, and it is billed at the row rate. From the second run you only get movement.
