Choosing the right tires can feel overwhelming, especially when you're staring at confusing numbers and letters on the sidewall. If you've been comparing 101V vs 105V tires, you're probably wondering what those numbers actually mean and whether they'll make any real difference for your driving.
Here's the deal: those numbers aren't just random codes. They tell you important things about how much weight your tires can handle and how fast they can safely go. And yes, the difference between 101V and 105V tires matters more than you might think.
In this guide, we'll break down everything you need to know about these two tire ratings. No confusing jargon, no complicated formulas—just straightforward information that'll help you make the right choice for your vehicle.
Key Takeaways
Before we dive deep into the details, here are the main points you should remember:
- Load index (the numbers) tells you weight capacity—101 means 1,819 lbs per tire, while 105 means 2,039 lbs per tire
- Speed rating (the V) is the same for both, meaning they can both handle speeds up to 149 mph
- 105V tires can carry about 220 pounds more per tire than 101V tires
- Your vehicle's manual specifies which load index you need—don't go lower than recommended
- Price difference is usually minimal, around $10-30 per tire
- The higher load rating often means stronger construction and better durability
What Do 101V and 105V Actually Mean?
Let's start with the basics. When you look at your tire sidewall, you'll see something like "225/45R17 101V." Those last three characters are what we're talking about today.
The number (101 or 105) is the load index. This tells you the maximum weight each tire can safely carry when it's properly inflated. It's not the actual weight in pounds—it's a code number that corresponds to a specific weight.
The letter (V in both cases) is the speed rating. This tells you the maximum speed the tire is designed to handle safely. A V rating means the tire is tested and approved for speeds up to 149 mph.
So when we compare 101V vs 105V tires, we're really looking at tires with different weight capacities but the same speed capability.
Understanding Load Index Numbers
The load index is probably the most important thing to understand when choosing between these tires. Each number on the load index scale represents a specific weight capacity.
For 101V tires, the load index of 101 means each tire can carry up to 1,819 pounds when properly inflated. That means all four tires together can support 7,276 pounds.
For 105V tires, the load index of 105 means each tire can handle up to 2,039 pounds per tire. Together, four tires can support 8,156 pounds.
That's a difference of 220 pounds per tire, or 880 pounds total for all four tires. For some vehicles, this difference is critical. For others, it doesn't matter much at all.

Speed Rating: The V Factor
Since both 101V and 105V tires share the same speed rating, let's talk about what that V actually means.
A V speed rating indicates the tire is engineered and tested to perform safely at speeds up to 149 mph. In the United States, where highway speed limits rarely exceed 80 mph, this gives you a huge safety margin.
The speed rating isn't just about top speed though. It also reflects the tire's overall performance characteristics, including handling, heat dissipation, and cornering stability at high speeds.
Here's something interesting: you should never install tires with a lower speed rating than what your vehicle manufacturer recommends. Your owner's manual specifies the minimum speed rating for a reason—it's matched to your car's performance capabilities.
Common Speed Ratings Explained
- Q: Up to 99 mph
- S: Up to 112 mph
- T: Up to 118 mph
- H: Up to 130 mph
- V: Up to 149 mph (our tires)
- W: Up to 168 mph
- Y: Up to 186 mph
What Type of Vehicles Need 101V Tires?
101V tires are commonly found on lighter vehicles. Think compact cars, sedans, and smaller crossovers.
Typical vehicles that use 101V tires include:
- Honda Civic
- Toyota Corolla
- Mazda3
- Volkswagen Jetta
- Smaller crossovers like Honda HR-V
These vehicles typically weigh between 2,800 and 3,500 pounds. When you add passengers, cargo, and a full tank of gas, the 101V load rating provides adequate capacity with a reasonable safety margin.
If your car came with 101V tires from the factory, it means the manufacturer calculated that this load index is sufficient for your vehicle's gross vehicle weight rating (GVWR).
What Type of Vehicles Need 105V Tires?
105V tires are designed for heavier vehicles or those that regularly carry substantial loads.
Common vehicles equipped with 105V tires:
- Mid-size SUVs (Toyota Highlander, Honda Pilot)
- Larger sedans (BMW 5-series, Mercedes E-Class)
- Performance sedans
- Some light-duty pickup trucks
- Vehicles regularly used for towing
These vehicles typically weigh more than 4,000 pounds and may have a GVWR approaching or exceeding 6,000 pounds. The extra load capacity of 105V tires ensures there's adequate safety margin even when the vehicle is fully loaded with passengers and cargo.
Performance Differences Between 101V vs 105V Tires
While the load index is the primary difference, there are some performance characteristics worth discussing.
Handling and Ride Quality
105V tires typically have reinforced sidewalls to handle the extra weight. This can result in slightly firmer ride quality compared to 101V tires. Some drivers describe it as a more "planted" feeling, while others find it less comfortable on rough roads.
101V tires, with their lighter construction, might offer a slightly softer, more comfortable ride on smooth highways.
Durability and Longevity
The heavier construction of 105V tires often translates to better durability, especially if you regularly carry heavy loads. The reinforced sidewalls resist damage better and may last longer under stress.
However, if you're putting 105V tires on a lighter vehicle that doesn't need the extra capacity, you won't necessarily see better tread life. In fact, the stiffer construction might wear unevenly if the vehicle isn't heavy enough to properly flex the tire.
Fuel Economy
Here's a small consideration: heavier tires with more robust construction can slightly impact fuel economy. The difference between 101V and 105V tires is minimal—maybe 0.1 to 0.2 mpg—but it exists.
For most drivers, this difference is too small to notice in real-world driving.
Price Comparison
When comparing 101V vs 105V tires, price is usually not a major deciding factor.
The difference in cost between these two load ratings is typically $10 to $30 per tire, depending on the brand and tire model. Premium brands like Michelin or Bridgestone might have a larger price gap, while budget brands often have minimal difference.
Here's the thing: you shouldn't choose based on price alone. If your vehicle requires 105V tires, installing 101V tires to save $40-80 total could be dangerous and void your vehicle's warranty.
Can You Use 105V Tires Instead of 101V?
This is a common question, and the answer is usually yes.
Installing tires with a higher load index than required is generally safe and acceptable. If your car came with 101V tires, upgrading to 105V tires won't cause any problems. You're simply adding extra load capacity and potentially durability.
The only potential downsides are:
- Slightly higher cost
- Potentially firmer ride quality
- Very minimal impact on fuel economy
Many drivers actually prefer using the higher load rating for peace of mind, especially if they occasionally carry heavy loads or plan long road trips with lots of luggage.
Can You Use 101V Tires Instead of 105V?
Here's where you need to be careful: downgrading is not recommended.
If your vehicle came with 105V tires from the factory, there's a reason for it. The manufacturer determined that your vehicle's weight and load capacity requires that minimum load index.
Installing 101V tires on a vehicle that requires 105V could result in:
- Tire failure under heavy loads
- Premature tire wear
- Compromised handling and safety
- Voided vehicle warranty
- Potential liability issues in case of an accident
Your vehicle's door jamb has a tire information placard that specifies the minimum load index required. Never go below that number.

How to Check What Your Vehicle Needs
Finding the right tire specification for your vehicle is easy. Here's where to look:
1. Driver's door jamb: Open your driver's door and look at the sticker on the door frame. It lists the tire size and load index your vehicle requires.
2. Owner's manual: The manual has a section on tires that specifies the approved tire sizes and ratings.
3. Current tires: If your car still has the original tires (or correct replacements), check the sidewall. The last three characters before any additional codes show the load index and speed rating.
4. Manufacturer website: Most car makers have tire specifications available online if you enter your vehicle's year, make, and model.
Never guess or assume. Always verify the correct specification before buying new tires.
Real-World Scenarios and Recommendations
Let's look at some common situations to help you decide between 101V vs 105V tires.
Scenario 1: Daily commuter in a Honda Civic If your Civic came with 101V tires, stick with them. You won't benefit from upgrading to 105V unless you regularly carry extremely heavy loads.
Scenario 2: Family road trips in a loaded SUV If your mid-size SUV requires 105V tires, definitely don't downgrade to 101V. The extra load capacity is essential when you've got five passengers, luggage, and cargo.
Scenario 3: Performance sedan enthusiast Many performance sedans use 105V or higher ratings. The reinforced construction helps with cornering loads during spirited driving.
Scenario 4: Occasional heavy hauling If your vehicle came with 101V but you occasionally carry very heavy loads, upgrading to 105V provides extra peace of mind, though check your GVWR limits first.
Making Your Final Decision
Choosing between 101V and 105V tires really comes down to three factors:
1. What does your vehicle require? This is non-negotiable. If your car needs 105V, you must use 105V or higher. If it came with 101V, you can safely use 105V if you want.
2. How do you use your vehicle? Regular heavy hauling, towing, or fully loaded trips benefit from the higher load rating.
3. Your budget: The price difference is usually small, but if cost is a major concern and 101V meets your needs, there's no reason to spend extra.

Q: Do I need to replace all four tires with the same load index? A: Yes, all four tires should have the same specifications, including load index and speed rating, for optimal safety and performance.
Q: Will 105V tires wear faster than 101V tires? A: Not necessarily. On a vehicle that needs the higher rating, 105V tires should last as long as 101V tires would on a lighter vehicle.
Q: Can I mix 101V and 105V tires on the same vehicle? A: No, you should never mix tires with different load indexes on the same vehicle. This creates handling imbalances and safety issues.
Q: Does the load index affect winter tire performance? A: The load index itself doesn't affect winter performance, but you must still match or exceed your vehicle's required load rating even with winter tires.
Conclusion
When it comes to 101V vs 105V tires, the choice isn't really about which is "better." It's about which one is right for your specific vehicle and driving needs.
The key difference is load capacity—105V tires can handle 220 pounds more per tire than 101V tires. Both have the same V speed rating, meaning they're safe for speeds up to 149 mph.
Always follow your vehicle manufacturer's recommendations. If your car requires 105V tires, never downgrade to 101V. If it came with 101V, you can safely upgrade to 105V if you want extra capacity or peace of mind.
The price difference between these two ratings is usually minimal, so don't let cost be your primary deciding factor. Safety and proper fitment should always come first.
Check your driver's door jamb or owner's manual to find your vehicle's tire specifications. When in doubt, consult with a qualified tire professional who can help you make the right choice for your specific situation.
Remember, tires are the only contact your vehicle has with the road. Choosing the correct specifications isn't just about following rules—it's about keeping you and your passengers safe on every journey.
