Tires being replaced:

The selected count multiplies every per-tire price and fee.

Tire and vehicle profile:

Used for price, installation, tire-life, and replacement-scope checks.

Tire price:

The basis prevents a set subtotal from being multiplied again.

A tire's advertised price is rarely the final amount paid at the shop. Mounting and balancing may be priced per tire or for the whole job, while alignment, valve or tire-pressure-monitoring service, disposal, road-hazard coverage, shipping, tax, and rebates can change the out-the-door total.

The first cost decision is scope. Replacing one tire, an axle pair, or a full set changes every per-tire charge. Replacing fewer than four can also raise fitment questions: tread depth, tire model, size, load index, speed rating, and vehicle-specific all-wheel-drive guidance may limit which combination is acceptable.

Price basis matters just as much as the number shown. A quote of 600 entered as a per-tire price becomes 2,400 for four tires; the same 600 entered as the full tire subtotal stays 600. Installation and optional fees need the same distinction so a set price is not multiplied twice.

Expected mileage turns a purchase total into a comparison measure, not a promise. Cost per 1,000 miles can make a higher-priced, longer-life tire easier to compare with a cheaper short-life option. Actual life still depends on alignment, inflation, rotation, road conditions, driving style, climate, damage, and ageing.

A cost estimate cannot decide when a tire is safe to use or which tire fits a vehicle. Follow the door placard and owner's manual, inspect tread and damage, and use a qualified tire professional when replacement scope or matching requirements are uncertain.

How to Use This Tool:

Enter the estimate in the same pricing basis and currency used by the seller's quote.

Choose 1, 2, or 4 Tires being replaced and select the closest tire and vehicle profile for planning checks.
Enter the tire price and specify whether it is per tire or the whole tire subtotal. Do the same for installation, using included when no separate charge applies.
Add alignment and any valve or TPMS service, road-hazard coverage, disposal fees, shipping, or other whole-job surcharge that actually appears in the quote.
Set the sales-tax rate and taxable portion, then enter any whole-purchase rebate. Keep every amount in the selected display currency because no exchange conversion occurs.
Compare Installed total with an optional shop out-the-door quote and inspect the cost ledger. A large variance should be reconciled line by line before purchase.

Interpreting Results:

Installed total is the component estimate after tax and the applied rebate. Shop quote variance equals the entered shop quote minus that estimate, so a positive value means the shop quote is higher and a negative value means it is lower.

Fees after tires includes installation, alignment, add-ons, tax, and net credits. A share of 40% or more triggers an itemization prompt, but it is not proof that the quote is excessive. Run-flat service, oversized tires, alignment work, taxes, or legitimate package charges can raise the share.

Annualized tire budget spreads the installed total over expected life using annual mileage. It is not a cash-flow schedule, warranty value, or prediction of the replacement date.

Technical Details:

Money inputs are rounded to integer minor currency units before invoice arithmetic. Tax is computed on the selected taxable base and rounded to the nearest minor unit. The display currency changes the symbol only; no exchange rate is used.

Formula Core

Let n be tire count, P the tire-price entry, I the installation entry, and A the sum of alignment and optional charges after their selected bases are applied.

\begin{matrix} P_{tires} = {\begin{matrix} nP & per-tire basis \\ P & whole-subtotal basis \end{matrix} \\ I_{total} = {\begin{matrix} nI & per-tire basis \\ I & whole-job basis \\ 0 & included \end{matrix} \end{matrix}

Pre-tax total Q is tires plus installation and all selected services. Taxable base B is either Q, the tire subtotal alone, or zero. Rebate R is applied after tax and cannot make the total negative.

\begin{matrix} Q = P_{tires} + I_{total} + A \\ T = round to minor unit (B \times \frac{tax rate}{100}) \\ R_{applied} = \min (R, Q + T) \\ installed total = Q + T - R_{applied} \end{matrix}

Mileage measures use the same installed total:

\begin{matrix} cost per 1,000 miles = \frac{installed total}{expected life miles} \times 1000 \\ annual budget = \frac{installed total}{expected life miles} \times annual miles \end{matrix}

For four tires at 165 each, installation at 32 per tire, a 110 alignment, and 7.5% tax on tires and services, the pre-tax total is 898. Tax rounds to 67.35 and the installed total is 965.35. Over 60,000 expected miles, that is about 16.09 per 1,000 miles.

Rule Core

Tire estimate basis and boundary rules
Choice	Rule	Important boundary
Tire count	Only 1, 2, or 4 is accepted	Every per-tire amount uses the selected count
Alignment	None contributes zero	An entered alignment amount is ignored in that mode
Tax basis	Tires and services, tires only, or no tax	Tax is applied before rebate
Quote match	Absolute variance below 1 currency unit counts as a match	Exactly 1 unit is reported as higher or lower
Fee-share prompt	Itemization prompt at ≥ 40%	The percentage is a review signal, not a price judgment

Safety and Accuracy Notes:

Use the vehicle manufacturer's size and inflation information, then confirm load index, speed rating, construction, tread matching, and axle placement with the owner's manual or a qualified installer. Cost bands and expected-life values are planning assumptions, not fitment approval.

Replace tires based on tread, damage, ageing, pressure loss, and professional inspection rather than cost alone.
Check whether mounting, balancing, TPMS service, disposal, alignment, road-force work, and warranties are included before comparing quotes.
Use the actual local tax rule and written shop estimate; the calculation does not determine taxability or consumer rights.
