Why Honda Grom Tire Size Is Necessary
From my experience riding the Honda Grom, I quickly realized how important the tire size is for both performance and safety. The Grom comes with a specific tire size designed to match its compact frame and lightweight build. Using the correct tire size ensures the bike handles as intended—giving me the right balance of grip, stability, and maneuverability, especially when carving through tight corners or city traffic.
I’ve also found that sticking to the recommended tire size helps maintain accurate speedometer readings and proper suspension behavior. If the tire size is off, it can throw off these elements, leading to a less predictable ride. Plus, tires that are too big or too small can put unnecessary stress on the wheels and brakes, which could cause premature wear or even safety issues. For me, knowing the right tire size means I can enjoy the Grom’s fun, nimble ride without worrying about compromising its performance or my safety.
My Buying Guides on Honda Grom Tire Size
When I first started looking into upgrading or replacing the tires on my Honda Grom, I realized how important it is to understand the correct tire sizes and what options are available. Here’s what I learned from my experience, which I hope will help you make the best choice for your Grom.
Understanding the Stock Tire Size
To begin with, I checked the stock tire sizes that come standard on the Honda Grom. Typically, the front tire size is 120/70-12, and the rear tire size is 130/70-12. Knowing these numbers is crucial because they tell you the tire’s width, aspect ratio, and rim diameter, which must match your bike’s specifications to ensure safety and performance.
What Do These Numbers Mean?
Breaking down the size helps me understand what I’m buying:
- 120/70-12 (Front tire): 120 mm width, 70% aspect ratio (height of the sidewall as a percentage of width), and fits a 12-inch rim.
- 130/70-12 (Rear tire): 130 mm width, 70% aspect ratio, and fits a 12-inch rim.
This means any replacement tires should closely match these dimensions unless you’re deliberately looking to modify the bike’s handling or appearance.
Choosing the Right Tire Type
Once I knew the size, I had to decide on the tire type. The Honda Grom is often used for city riding, occasional track days, or even some light off-road adventures, so tire choice depends on your use case:
- Street Tires: Best for everyday riding, providing good grip and longevity.
- Sport Tires: Offer better traction and handling but might wear out faster.
- Dual Sport/Off-road Tires: Suitable if you plan to take your Grom on dirt trails or rough surfaces.
I personally went with a high-quality street tire that matched the stock size to keep my ride safe and smooth.
Considering Aftermarket Sizes
Some riders like to experiment with wider or differently profiled tires for aesthetics or altered handling. If you’re thinking about going up or down in size, keep in mind:
- Changing the rim diameter is generally not recommended as it requires new wheels.
- Slight increases in width or aspect ratio can affect speedometer accuracy, handling, and clearance.
- Always double-check clearance to avoid rubbing against the swingarm or fender.
I stuck with the OEM sizes for peace of mind but explored aftermarket tires within those specs.
Where to Buy and What to Look For
When purchasing, I recommend:
- Buying from reputable dealers or trusted online stores to ensure genuine products.
- Checking tire reviews specifically for the Honda Grom or similar-sized bikes.
- Considering brands known for quality and durability like Michelin, Pirelli, or Dunlop.
I also made sure to check the manufacturing date on the tires to avoid old stock that could degrade performance.
Final Tips From My Experience
- Always replace front and rear tires as needed but not necessarily at the same time unless wear is even.
- Proper tire pressure is key for performance and longevity—check your owner’s manual for recommended PSI.
- Regularly inspect tires for wear, punctures, or damage, especially if you ride frequently.
By understanding the Honda Grom tire size and matching it with quality tires, I’ve maintained great control and safety on my rides. I hope my guide makes your tire buying process smoother and more confident!
