<h2>What the Data Shows</h2>
<div class="cards">
<div class="card">
<div class="card-icon">📊</div>
<h3>Average Lifespan: ~42,000 miles</h3>
<p>Across five completed sets, tires lasted between 29,000 and 56,000 miles. Florida heat, highway driving, and Prius regen braking all affect wear.</p>
</div>
<div class="card">
<div class="card-icon">🌧️</div>
<h3>Wet Weather Is the Real Test</h3>
<p>Every set started slipping in rain before the tread technically wore out. In Florida, wet traction degrades well before you reach the wear bars. Replace when wet grip drops — don't wait for the tread indicator.</p>
</div>
<div class="card">
<div class="card-icon">🏪</div>
<h3>Costco Was Usually the Best Deal</h3>
<p>Costco pricing (including installation) beat most competitors after rebates. The membership pays for itself on one tire purchase if you weren't already a member.</p>
</div>
<div class="card">
<div class="card-icon">⚠️</div>
<h3>Warranty Miles Are Optimistic</h3>
<p>Every set was warranted for 70k–80k miles. None lasted that long in real-world South Florida use. Don't buy tires based on warranty mileage alone.</p>
</div>
</div>
<h2>2013 Michelin Defender Price Shopping Research</h2>
<p>At 117,000 miles, before buying the Defender XT set, every major retailer was compared. This kind of research pays off — prices varied by nearly $300 for the same tire:</p>
<div class="table-wrap">
<table>
<thead>
<tr><th>Retailer</th><th>Tire</th><th>Final Price (after rebates + install + tax)</th></tr>

<tbody>
<tr><td>TireRack + local install</td><td>General Altimax RT</td><td>$345 ✅ Cheapest overall</td></tr>
<tr><td>TireRack + local install</td><td>Bridgestone Ecopia EP422</td><td>$454</td></tr>
<tr><td>TireRack + local install</td><td>Michelin Defender</td><td>$482</td></tr>
<tr><td>TireBuyer.com + local install</td><td>Michelin Defender</td><td>$485</td></tr>
<tr><td>Costco (incl. membership)</td><td>Michelin Defender XT</td><td>$545</td></tr>
<tr><td>Tire Kingdom</td><td>Michelin Defender</td><td>$502</td></tr>

</div>
<div class="notice tip">
<strong>Shopping tip:</strong> Always check TireRack for the base price, then factor in local installation ($60 is typical). Apply any credit card rebates before comparing. The cheapest tire isn't always the best — the General Altimax at $345 was $137 less than the Michelin, but the Michelin has better wet traction ratings which matters in Florida rain.
</div>
<h2>Rotation & Maintenance</h2>
<div class="notice warning">
<strong>Rotate every 5,000–7,500 miles on a Prius.</strong> Regenerative braking puts more wear on the front tires than a conventional car. Skipping rotations will cut tire life significantly — the front tires will wear out while the rears still have tread.
</div>
<ul>
<li>Prius uses a front-heavy regen braking bias — front tires wear faster than rear</li>
<li>Tire pressure: <strong>35 PSI front, 33 PSI rear</strong> (check cold, per door placard). The TPMS will warn when pressure drops 25% below placard (~26 PSI front, ~25 PSI rear) — don't wait for that light</li>
<li>The Gen 2 TPMS monitors pressure only — it does not tell you which tire is low until it's significantly underinflated</li>
<li>Check pressure monthly in Florida — heat causes pressure to fluctuate more than in cooler climates</li>
</ul>
<h2>Notes from the Field</h2>
<div class="story-box">
<p>
Over 17 years, tires were the most frequent recurring expense on this car — more than any single repair. The pattern was consistent: good grip for the first 30,000 miles, acceptable grip to about 40,000, then a noticeable drop in wet-weather confidence in Florida rain.
</p>
<p>
The Bridgestone Ecopia EP422+ was the best for fuel economy — it's a true low-rolling-resistance tire and you can feel the difference in highway MPG. The Michelins lasted longer and had better wet grip. The Goodyears were fine but nothing special.
</p>
<p>
For anyone still driving a high-mileage Gen 2 in Florida: check your tires in the wet season. A 45,000-mile tire in South Florida heat and rain is not the same as one in a drier climate.
