Choosing the right tire size for your motorcycle can feel overwhelming, especially when you're staring at numbers and letters that look like secret codes. If you're trying to decide between MT90B16 vs 130/90B16, you're not alone. These two tire sizes are super popular for cruisers and touring bikes, but they're not exactly the same thing.
Here's the deal: both sizes actually refer to almost identical tires, but they use different measurement systems. One uses the old-school alpha-numeric system (MT90B16), while the other uses the newer metric system (130/90B16). Sounds confusing? Don't worry. By the end of this article, you'll know exactly what each size means, how they perform, and which one is the better choice for your bike.
Understanding Motorcycle Tire Sizes
Before we jump into comparing mt90b16 vs 130/90b16, let's break down what these numbers actually mean.
For the MT90B16 tire:
- M = Motorcycle tire
- T = Width code (roughly 130mm wide)
- 90 = Aspect ratio (height is 90% of width)
- B = Belted bias construction
- 16 = Rim diameter in inches
For the 130/90B16 tire:
- 130 = Width in millimeters
- 90 = Aspect ratio (height is 90% of width)
- B = Belted bias construction
- 16 = Rim diameter in inches
See the pattern? They're basically the same tire measured in different ways. The metric size just gives you more precise information upfront.

The Real Difference Between MT90B16 and 130/90B16
Here's the truth: when you compare MT90B16 vs 130/90B16, you're looking at functionally identical tires. The main difference is just how manufacturers label them.
The MT90B16 uses an older sizing system that was popular in the 80s and 90s. The metric 130/90B16 sizing became more standard in recent years because it's more precise and easier for people to understand across different countries.
Many tire manufacturers make the same tire model available in both size designations. For example, a Dunlop D402 might be listed as both MT90B16 and 130/90B16 on diffrent websites. According to industry experts at big write hook, this dual labeling system helps accommodate older bike manuals that still reference alpha-numeric sizes.
Physical Dimensions and Fitment
When mounting either an mt90b16 vs 130/90b16 tire, you'll find they fit the same rim width range, typically 3.5 to 4.0 inches.
Actual Measurements:
- Overall diameter: approximately 25.3 inches
- Section width: around 5.1 inches
- Tread width: typically 4.3-4.5 inches
Both sizes work perfectly on popular cruiser models like:
- Harley-Davidson Sportster (rear)
- Honda Shadow 750
- Yamaha V-Star 650
- Suzuki Boulevard S50
Your bike's owner manual might list one format or the other, but either will work as long as the load rating and speed rating match your needs.
Performance Characteristics
Since MT90B16 and 130/90B16 are the same physical size, their performance is identical when comparing the same tire model and brand.
Handling and Stability
The 90 aspect ratio gives these tires a taller sidewall compared to sportbike tires. This provides:
- Better cushioning over bumps
- More stable cruising on highways
- Easier low-speed maneuverability
- Comfortable ride quality for long distances
The belted bias construction (that "B" in the size) offers a nice middle ground between old-school bias-ply tires and modern radials. You get decent handling without the harsh ride of some radial tires.
Cornering Ability
These tire sizes aren't designed for aggressive cornering like you'd do on a sportbike. They're made for cruisers that spend most time upright or in gentle leans. The rounded profile works great for:
- Sweeping highway curves
- Relaxed canyon rides
- City navigation
- Parking lot manuevers
Wet Weather Performance
Modern tires in both the mt90b16 vs 130/90b16 sizes come with decent rain grooves and compounds that work in wet conditions. However, performance varies way more by tire model than by size designation. A premium Michelin or Metzeler will outperform a budget tire every time, regardless of whether the label says MT90B16 or 130/90B16.
Load Rating and Speed Rating
This is where things get important. The size itself (whether you call it MT90B16 or 130/90B16) doesn't tell you the whole story. You also need to check the load index and speed rating.
Common Load Indexes:
- 72 = 783 lbs capacity
- 73 = 805 lbs capacity
- 74 = 827 lbs capacity
Common Speed Ratings:
- H = up to 130 mph
- V = up to 149 mph
Most cruisers using this tire size will have a 72H or 73H rating, which is plenty for normal riding. Always match or exceed your bike manufacturer's specifications. Don't just look at whether it says mt90b16 vs 130/90b16 – check those extra letters and numbers too.
