A second set of tires for a car that already has tires.
A second set of tires, used half the year, bought for a risk rather than a return.
Winter tires get the normal sales tax. They are an odd purchase because you are buying a duplicate — a second set for a car that already has some. You are paying for safety, not for anything you can see. One thing does come back to you though: your summer tires spend half the year in a garage instead of on the road, so they last longer.
Winter tires are taxed as ordinary goods. What makes them unusual is that they are a duplicate purchase — a second set for a vehicle that already has tires — bought against a risk rather than a benefit. They also extend the life of the summer set, which offsets part of the cost in a way the sticker never shows.

Your position in the tax system
29.65% on the next dollarEvery extra dollar you earn is taxed at your marginal rate, not your average one — which is why a purchase costs more to fund than a paycheck stub suggests.
Marginal rates are read in gross-income terms: below the standard deduction an extra dollar of pay adds nothing to taxable income, so the true rate there is 0%, not the lowest bracket's. Excludes pre-tax deductions (401(k), HSA), which would lower all three.

Each tax layer is the extra tax this purchase causes — that layer's tax at your income subtracted from its tax at your income plus the gross-up — so bracket boundaries the purchase straddles are handled correctly rather than smoothed over with an average rate.
Is a raise actually a raise?
you keep 70%A raise arrives on top of everything you already earn, so it is taxed at your marginal rate — not the average rate on your whole salary.
Federal, FICA, state and any local income tax — no pre-tax deductions, benefit changes, or payroll withholding quirks, all of which move the real figure. Moving into a higher bracket never taxes the income below the threshold: only the dollars above it pay the higher rate.
