The months on this calendar are ranked by how deep tire promo codes actually run — the share of stores SimplyCodes tracked in each month whose deepest code took 25% off or deeper, pooled across every year on record and re-measured daily. The reading is cross-retailer on purpose: when one chain runs its sale is a different question from when the whole tire market discounts hardest, and only the second one tells you which month to buy in.
December is the best month to buy tires with a promo code. Across every year SimplyCodes has tracked, 13.9% of tires stores running a percentage-off code in December had one at 25% off or deeper — the highest share of any month, and 8.9 points above the weakest month (February, 5.0%). Figures cover 1,172 store-months across the tire and wheel retailers SimplyCodes tracks — each store counted once for every month it ran a percentage-off code — as of September 2, 2026.
- December is the strongest month for tires discounts — 13.9% of the tires stores SimplyCodes tracked had a code 25% off or deeper that month, across 108 store-months measured.
- October is the runner-up at 13.5% — worth knowing if you miss December, and the reason this calendar is worth reading past its headline.
- February is the weakest month at 5.0% — a 8.9-point gap from December. Buying tires in February means shopping the year's thinnest discount pool.

Deep-discount share = the share of that month's tires stores whose deepest percentage-off code was 25% off or more · bar = that share relative to the strongest month · store-months = the denominator behind each share, one per store per month it ran a percentage-off code · — = fewer than 3 retailers contributed that month, so no share publishes · free ship / free gift = at least one such offer verified in that month.

Frequently asked questions
When is the best time to buy tires?
The calendar above names the strongest month, its share of deep-discounting stores, and the date the snapshot was taken. Across every year SimplyCodes has tracked, deep-discounting tire stores have clustered in the second half of the year and thinned out from winter through early summer, so a first-half purchase draws from the year's shallowest code pool.
What month are tires cheapest?
Cheapest and deepest-discounted are not the same claim, and this study only makes the second one. It ranks months by the share of tire stores whose deepest code ran 25% off or deeper across the tire and wheel retailers SimplyCodes tracks. Tire list prices move with rubber costs and model changeovers that no coupon feed can see, so treat the peak month as the best code window rather than a guaranteed low price. The retailers behind it are Discount Tire, Tire Rack, Priority Tire, Belle Tire, Tire Agent, SimpleTire, Goodyear, Tires Easy, Big O Tires, Midas and the rest of the sector.
Do tire retailers run promo codes at all, or only rebates?
Both, and the split changes how you plan a purchase. Tire sellers lean harder on mail-in rebates, installation bundles and mounted-price cuts than most retail sectors do, which is why deep tire codes are rarer than the buying guides imply. The codes that do land are real and verified. There are simply fewer deep ones in a typical tire month.
Does a deep tire discount mean the code will work at checkout?
They are separate questions. Depth is how much a code takes off, and reliability is whether it still applies at checkout — the Health Score (SimplyCodes' 0–100 measure of how likely a code is to work at checkout) on each code covers the second one. This calendar reads depth only, and each retailer's own SimplyCodes page carries its current working codes.
Methodology
How SimplyCodes verifies codes. Behind every figure in this live data study is the SimplyCodes verification system. Coupon codes are tested at real checkout before they are listed, through three independent layers: daily automated testing, where headless browsers run through real checkout flows and record whether a discount actually applies. A human verification network of 10,000+ verifiers submits screenshot-and-timestamp proof. And a real-time fleet signal, where live checkout outcomes feed back into the engine. The calendar below summarizes that verification history month by month.
How this calendar is built. we take every store among the tire and wheel retailers SimplyCodes tracks and record, for each calendar month that store ran a percentage-off code, the deepest discount it offered that month — so "December" means every December on record, not one year's. For each month we report the share of those stores whose deepest code reached 25% off or more, alongside the number of store-months behind the share. This measures how many stores discount deeply in a given month, not how many individual codes did. Only percentage-off codes are counted, because fixed-amount offers are not comparable across price points. Percentage claims of 95% or more are excluded as implausible. And a month contributed by fewer than 3 retailers publishes no share at all
