Picking the right tire for your motorcycle can feel like reading a foreign language. You're staring at numbers and letters, wondering what they all mean and which one will keep you safe on the road. Today, we're breaking down two popular tire sizes: mt90b16 vs 130/90b16.
Here's the thing - these aren't actually different sizes at all. They're the same tire, just written in different measurement systems. But understanding what that means for your bike matters more than you might think.
Key Takeaways
Before we dive deep, here's what you need to know:
- MT90B16 and 130/90B16 are the exact same tire size
- MT90B16 uses the older alpha-numeric system
- 130/90B16 uses the modern metric system
- Both fit the same 16-inch rim
- You can swap between these designations freely
- The width is approximately 130mm (5.1 inches)
- These tires are commonly used on cruisers and touring bikes
Understanding Motorcycle Tire Sizes
Let's start with the basics. Motorcycle tires use different naming systems, and that confuses alot of riders.
The alpha-numeric system (like MT90B16) was popular in the past, especially for American motorcycles. The metric system (like 130/90B16) is what most manufacturers use today.
Think of it like measuring distance in miles versus kilometers. The road is the same length - you're just using different rulers.
Breaking Down MT90B16
Let's decode what MT90B16 actually means:
- M = Motorcycle tire
- T = Width code (approximately 130mm)
- 90 = Aspect ratio (height is 90% of width)
- B = Belted bias construction
- 16 = Rim diameter in inches
The "T" in this system corresponds to a tire that's about 5.1 inches wide. Each letter represents a different width range, which is why this system can be confusing.
Breaking Down 130/90B16
Now for the metric version:
- 130 = Width in millimeters
- 90 = Aspect ratio (height is 90% of width)
- B = Belted bias construction
- 16 = Rim diameter in inches
This system is more straightforward. You can see exactly how wide the tire is without memorizing a chart.

Which Bikes Use These Tire Sizes?
Both tire designations fit the same motorcycles. You'll commonly see them on:
- Harley-Davidson Sportsters
- Honda Shadow models
- Yamaha V-Star cruisers
- Kawasaki Vulcan series
- Suzuki Boulevard bikes
These mid-size cruisers and touring bikes benefit from the wider profile and comfortable ride these tires provide.
Performance Characteristics
Since mt90b16 vs 130/90b16 are identical sizes, they perform exactly the same way. Here's what you can expect:
Handling and Stability
The 130mm width gives you good contact with the road without being too wide. You get stable handling in corners and confidence when riding straight. The 90 aspect ratio means the sidewall is tall enough to absorb bumps but not so tall that the bike feels wobbly.
Ride Comfort
That taller sidewall acts like a cushion between you and the road. If you ride on streets with potholes or rough pavement, this tire size will make your ride more comfortable than a lower-profile tire.
Traction
The contact patch - that's the part of the tire touching the road - is wide enough for good grip in most conditions. You'll have decent traction in rain and excellent grip on dry roads.
Longevity
Most riders get between 8,000 to 15,000 miles from these tires, depending on riding style and tire brand. Cruiser riders who do mostly highway miles get the most life from their tires.
Price Comparison
Here's where things get interesting. Sometimes you'll find the MT90B16 designation priced differently than the 130/90B16, even though they're the same tire. This happens because:
- Older stock might be marked with the alpha-numeric code
- Some retailers don't realize they're identical
- Different brands prefer different designation systems
Pro tip: Search for both designations when shopping. You might find a better deal on one versus the other, even though you're getting the exact same size.
According to industry sources like justaskgenie, understanding tire designations can save riders money by expanding their search options.
Pros and Cons
Advantages of This Tire Size
Comfortable ride quality - The taller sidewall absorbs road imperfections better than low-profile tires.
Good for cruisers - The width and profile complement the riding style of most cruiser motorcycles.
Widely available - Almost every tire manufacturer makes this size, giving you lots of options.
Decent handling - You get stable cornering without sacrificing comfort.
Affordable - This common size means competitive pricing from multiple brands.
Disadvantages
Not for sport riding - If you want aggressive cornering, you need a different tire profile.
Limited speed ratings - Most tires in this size aren't designed for high-speed riding.
Heavier than sport tires - The construction adds weight compared to performance-oriented tires.
Less responsive - The taller sidewall flexes more, which reduces sharp handling response.
Popular Tire Brands in This Size
When shopping for mt90b16 vs 130/90b16 tires, you'll find these respected brands:
Dunlop
Known for excellent wet weather performance and long tread life. Their D401 and D402 models are popular choices.

Installation and Fitment
When replacing your tires, keep these points in mind:
You can switch between the MT90B16 and 130/90B16 designations without any problems. They mount the same way on the same rims.
Always replace tires in pairs when possible. Mixing old and new tires affects handling.
Check your motorcycle's manual for the recommended tire pressure. Just because two tires are the same size doesn't mean they use the same pressure.
Consider the load rating if you carry a passenger or luggage frequently. Some tires handle weight better than others.
Which One Should You Choose?
This is a trick question. Since mt90b16 vs 130/90b16 are identical, you're not really choosing between different tires. You're just seeing the same size written two different ways.
What you should focus on is:
Brand reputation - Stick with known tire manufacturers who stand behind their products.
Tread pattern - Different patterns work better for different riding conditions.
Price - Compare prices using both designation systems to find the best deal.
Reviews - See what other riders say about specific tire models.
Riding style - Match the tire's characteristics to how and where you ride.
Common Misconceptions
Let's clear up some confusion about these tire sizes:
Myth: MT90B16 is an American tire and 130/90B16 is foreign. Truth: They're the same tire, just different measurement systems.
Myth: One designation is newer/better than the other. Truth: Neither is superior - it's just different ways to write the same size.
Myth: You can't mix these designations on front and rear. Truth: You can use whichever designation you find, as long as the front and rear sizes match your bike's requirements.
Myth: Metric tires perform better. Truth: Performance depends on the tire construction and compound, not the naming system.
Maintenance Tips
Regardless of which designation you choose, proper tire maintainence extends their life:
Check pressure weekly when tires are cold. Under-inflated tires wear faster and handle poorly.
Inspect for damage regularly. Look for cuts, punctures, or objects stuck in the tread.
Monitor tread depth. Replace tires when they reach the wear indicators.
Avoid harsh acceleration and braking. Smooth riding extends tire life significantly.
Store your bike properly in winter. Keep tires off cold concrete if possible.
Real-World Riding Experience
Riders who use these tire sizes generally report satisfying experiences for cruising and touring. The combination of comfort and handling works well for:
- Weekend rides on twisty back roads
- Long highway trips
- Daily commuting
- Two-up riding with a passenger
Where they fall short is aggressive sport riding or off-road use. But that's not what they're designed for anyway.
Final Verdict
So what's the verdict in the mt90b16 vs 130/90b16 debate? There isn't one - because there's no actual difference.
Understanding that these are the same tire frees you up to focus on what really matters: finding a quality tire from a reputable manufacturer that fits your riding style and budget.
Don't get hung up on the designation. Instead, compare:
- Tread patterns for your typical riding conditions
- Brand reputation and warranties
- Price across different retailers
- Reviews from riders with similar bikes
The "better" choice is simply whichever tire model gives you the performance you need at a price you can afford.
