Understanding the difference between OEM and aftermarket tires becomes crucial when it's time to replace what's on your vehicle. OEM tires (Original Equipment Manufacturer tires) come standard on new vehicles, selected by automakers to deliver specific performance characteristics. These factory-installed options meet the exact handling, safety, and performance requirements set by your vehicle's manufacturer.
OEM tires deliver reliable performance under normal driving conditions. Aftermarket tires, however, represent any replacement options that differ from your original equipment. These include different brands, models, or specifications than what came with your vehicle. The term "aftermarket" doesn't mean inferior quality—many aftermarket options match or exceed original equipment performance. You'll find aftermarket choices ranging from budget-friendly to premium, each offering different performance characteristics and price points.
When your current tires have served you well, replacing them with identical OEM options makes perfect sense. But knowing the key distinctions between OEM and aftermarket choices helps you make better decisions based on your performance needs, driving conditions, and budget. We'll break down what separates these tire categories and help you determine which option suits your specific driving situation.
Tire manufacturing involves distinct processes that create the fundamental difference between OEM and aftermarket tires.
OEM (Original Equipment Manufacturer) tires come factory-installed on new vehicles through extensive collaboration between automakers and tire manufacturers. This isn't a random selection process—vehicle manufacturers work directly with tire companies during vehicle development to engineer tires that meet specific performance targets.
Manufacturers rely on "spider charts" during development to evaluate multiple performance characteristics including tread life, wet traction, handling, road noise, and rolling resistance. This collaborative process ensures tires complement the vehicle's unique attributes such as weight distribution, suspension tuning, and braking systems.
Automakers invest substantial resources in this tire selection process because they recognize that even advanced suspension systems fail without properly matched tires. The result delivers the exact ride quality, handling characteristics, and fuel efficiency the vehicle was engineered to achieve.
Aftermarket tires become available after your vehicle leaves the factory. Unlike OEM tires engineered for specific vehicle models, aftermarket options fit multiple makes and models. This broad compatibility gives drivers flexibility to choose tires based on their specific needs, preferences, and budget requirements.
Aftermarket tire manufacturers often specialize in particular performance elements like enhanced traction, improved fuel efficiency, or reduced road noise. The aftermarket marketplace includes options from numerous retailers, online vendors, and select dealerships.
The core distinctions between these tire categories include:
Design focus: OEM tires match vehicle specifications for consistent performance; aftermarket tires offer flexibility to emphasize specific performance characteristics
Customization potential: Aftermarket tires allow changes in tire aspect ratio and width, affecting grip, braking distance, and ride comfort
Availability and options: Aftermarket tires provide more brand choices and often competitive pricing compared to OEM equivalents
OEM tires preserve the manufacturer's intended driving experience, while aftermarket options enable customization based on individual preferences and specific driving conditions.
Performance differences between OEM and aftermarket tires directly impact your driving experience, safety, and long-term value.
Automakers spend considerable resources—sometimes up to $1 million—developing tires that balance multiple characteristics for their vehicles. OEM tires undergo extensive testing to achieve the specific handling profile manufacturers want. They're calibrated to enhance particular vehicle attributes, whether that's delivering the smooth ride of a luxury sedan or the sharp cornering of a sports car.
Aftermarket tires give you the freedom to adjust this balance based on your preferences. High-performance aftermarket options might deliver sharper handling but sacrifice some comfort. The difference becomes clear in testing—when comparing identical-looking Michelin Pilot Sport 4S tires, the OEM-specific version produced lap times two seconds faster than their aftermarket counterparts.
Rolling resistance significantly affects fuel economy, accounting for 20-30% of fuel consumption in gas-powered vehicles. Many OEM tires prioritize low rolling resistance to maximize efficiency ratings, especially important for hybrids and electric vehicles seeking extended range.
Manufacturers like Continental have reduced rolling resistance in passenger-car tire portfolios by approximately 15% over the past decade. Studies show that a 10% reduction in rolling resistance translates to roughly 1% improvement in fuel economy. However, switching from fuel-efficient touring tires to high-performance options can decrease efficiency by 3-8%.
OEM tires typically deliver 30,000-50,000 miles, though many drivers experience shorter lifespans because manufacturers often prioritize comfort over longevity. This reflects the balance automakers strike—softer compounds improve ride quality but wear faster.
Aftermarket options offer a spectrum of durability choices. Performance-oriented tires use specialized compounds that enhance grip but reduce longevity, while touring-focused alternatives emphasize extended tread life, sometimes reaching 70,000-85,000 miles. This variety allows you to select tires matching your specific needs rather than accepting the compromise built into OEM selections.
Budget considerations play a major role when choosing between OEM and aftermarket tires. The price gap between these options can surprise vehicle owners shopping for replacements.
OEM tires command premium pricing due to their vehicle brand association and specialized manufacturing processes. Dealerships provide convenient service but charge accordingly—though some offer price match guarantees on select tire brands. Manufacturers sometimes provide rebates ranging from $15 to $60 per tire to help offset higher costs. However, OEM tire selection stays limited, offering fewer customization opportunities.
Aftermarket options deliver substantial savings—typically 10% to 50% on major tire brands. We carry the best selection of aftermarket tires at competitive prices. Pricing varies by size: 17-inch options start around $232.99, while 19-inch sizes run between $303.99-$406.99.

Aftermarket tires excel at customization possibilities. You can select tires emphasizing specific performance aspects, such as improved cornering handling or extended tread life. Many enthusiasts use this opportunity to try different tire combinations, including staggered fitments with varied sizes front to back. Changing tire aspect ratio and width can dramatically impact grip, braking distance, and ride comfort. Save on Aftermarket Tires without compromising quality—aftermarket options allow you to prioritize essential features without unnecessary expenses.
The aftermarket marketplace offers choices OEM simply can't match. Whether you need all-season reliability, performance grip, or maximum tread life, aftermarket selections provide the customization freedom to get exactly what your driving demands.
Choosing between OEM and aftermarket tires comes down to your specific driving needs and priorities. Here's how to make the right decision for your situation.
OEM tires make the most sense when you want to preserve your vehicle's original performance characteristics. Stay with OEM options if your car's handling has satisfied you since you bought it. These tires maintain the exact performance attributes your manufacturer engineered and ensure your vehicle's safety systems work as intended. Vehicles with sophisticated handling or those still under warranty typically benefit most from sticking with original equipment replacements.
Aftermarket options excel when you're seeking performance improvements beyond factory specifications. Consider aftermarket alternatives when you want enhanced grip, sportier handling, a smoother ride, better fuel economy, or specialized off-road capability. Save on Aftermarket Tires without compromising quality—these options offer extensive customization possibilities and typically cost significantly less than OEM equivalents.
Your driving style and environment should guide your tire selection. Automakers reveal their priorities through OEM tire choices—hybrids come with low rolling resistance options, while off-road vehicles feature aggressive tread patterns. Consider what matters most for your driving: maximum wet weather traction, quiet highway cruising, or extended tread life.
Several methods help you identify original equipment tires. Look for special markings or symbols molded into the tire sidewall. When shopping online, search for tires marked as "Original Equipment Fitment". Your vehicle's documentation often includes this information as well.
