27-inch tires Feature I 700c Vs 27 Inch Bike Tires

Tread Design:

700c Vs 27 Inch Bike Tires

The tire tread design is one of the most important features to consider when choosing the right tire for your vehicle. The tread design can vary depending on the manufacturer and purpose of the tire, but most tires have a pattern that allows them to grip any ground or terrain. This means that the right tire tread design can provide better handling, traction and stability, whether you’re driving on wet or dry roads, icy or snowy conditions, or off-road terrain. 

Tires with a deeper tread design are ideal for off-road and winter driving because they offer better traction in muddy or snowy conditions. The deeper grooves in these tires help to channel water away from the contact patch between your car’s tires and the road surface.


The 27-inch tires are an excellent choice for drivers who want to enjoy a comfortable and smooth ride. These tires feature radial construction, a popular technology offering better flexibility and comfort. The radial design allows the tire’s sidewall to flex more easily, leading to a smoother ride over bumps and rough terrain.

Its construction also makes them durable and long-lasting. The radial design distributes the tire’s weight evenly across the entire tread area, reducing wear on individual tire sections. This results in longer tread life, so you don’t have to replace your tires as often. 

Rim Diameter:

27-inch tires are popular for vintage bicycles manufactured in the 1970s and 1980s. These tires have distinct features, one of which is their rim diameter. The rim diameter of this type of tire is usually 630mm or around 24.8 inches, making them slightly larger than modern-day wheels. The issue with 27-inch tires is that finding replacement tires can be challenging due to their size. 

Bike manufacturers still produce these types of tires because many vintage bicycles still use them. If you need a new tire for your classic bike, ask your local bike shop to order one for you. 

Aspect Ratio:

These tires have an aspect ratio of 1 (100 Series), which is the tire’s height relative to its width. The aspect ratio affects your vehicle’s overall performance and handling, making it an important consideration when selecting new tires.

The 100 Series aspect ratio means that the height of these 27-inch tires is equal to their width. This makes them ideal for vehicles that require a sturdy and stable tire option, such as SUVs or trucks. The shorter sidewalls also help with better steering response and improved handling around corners, providing a more sporty feel while driving.


Depending on the model of the bicycle, 27-inch tires can come in two different widths, 1-1 8 inches and 1-3 8 inches.

The wider width offers more stability and control when riding on uneven surfaces such as dirt roads or gravel paths. It also provides better traction when navigating through wet conditions, making it an ideal option for riders who live in areas with frequent rain or snow. Wider tires offer a smoother ride by absorbing more shock from bumps and potholes on the road. Narrower tires and Pirelli P Zero Nero are lighter and faster than their wider counterparts.

The pros and cons of the 27-inch bicycle wheel:


  • The wheel comes in perfect condition and is assembled in advance without a side wobble, making it easy to set up without adjustments.
  • The aluminium rim provides resistance for a smooth and comfortable ride.
  • The endurance of the build allows it to tackle various terrains with ease.
  • Its ability to handle different types of terrain indicates its long-lasting nature.
  • The old-style design adds aesthetic appeal.


  • Trim strips are not included in the purchase and must be bought separately, adding expense.
  • Lack of compatibility with some bike models due to size differences.

700c tires

Tread Design:

700c tires are a popular choice for cyclists upgrading their road bikes. These tires are known for their durability and efficient performance, making them a favourite among amateur and professional riders. 

The tire’s grooves provide ample grip on uneven surfaces, allowing riders to navigate different terrains easily. This tread design also ensures that the tire lasts longer by reducing wear and tear caused by friction with the road. Cyclists can enjoy a smoother ride while saving money in the long run.


The new radial construction of 700c tires is a game-changer in cycling. This innovative tire design features cords that run at a 90-degree angle to the direction of travel, creating a more stable and comfortable ride experience on all types of roads and terrains. 

Rim Diameter:

The 700c tire has been popular for road bikes and touring bicycles. The term 700c refers to the tire’s outer diameter, which measures approximately 27.5 inches or 622mm in metric units. Due to their lightweight construction, this size is typically used for higher-end road bikes and touring bicycles.

The rim diameter of the 700c tire is also known as bead seat diameter (BSD), which determines the compatibility between tires and rims. Most modern tires are designed to fit on rims with a BSD of 622mm, making it easier for riders to find compatible components.

Aspect ratio:

The aspect ratio of a tire is the height of the sidewall in relation to its width. For these tires, the aspect ratio is mostly 10.58. This means that the height of the sidewall is approximately 10.58% of its width.

A lower aspect ratio usually indicates a tire with better handling and cornering abilities, as it has a shorter sidewall and less flex during turns. Higher aspect ratios provide cushioning and comfort on bumpy roads or longer rides.


The width of these tires ranges from 23mm to 26.5 mm, and each size offers its own unique benefits depending on your preferences and riding style.

If you want speed and agility, a narrower tire width may be the way to go. A 23mm tire will provide less rolling resistance and make it easier for you to accelerate quickly. This can be especially beneficial if you do a lot of road racing or want to improve your overall speed.

Wider tires offer more stability and comfort when riding over uneven terrain. A 26.5 mm tire will absorb more shock and vibration than a narrower option, which could make your ride feel smoother overall.

The pros and cons of the 700c Bicycle wheel


  • Superior performance and ride quality compared to small wheel folders.
  • Standard size makes it easier to find replacement parts.
  • Durable and continues to deliver a fun and comfortable experience even after extended use.
  • No alignment or trueing is required out of the box.
  • Lightweight and smooth feeling on roads, especially over 17mph.
  • Assembly of parts is required upon purchase, although the process is simple enough for most.
  • The larger size and weight may pose a challenge during braking.


  • Braking may prove to be a challenge due to the wheel. It is advisable to practice braking techniques beforehand on rainy days.

So Which tire do you need 27, an Inch or 700C bike tires?

There are numerous factors to consider when selecting the appropriate bicycle tire. The size of your bike wheels is one of the most important. If you own an old or vintage bike, chances are it came with 27-inch tires. These tires have been around for decades and remain popular due to their efficiency and affordability. They’re also easy to find at most bike shops.

You’ll need something different if you own a road bike, hybrid or 29-inch MTB. These bikes require 700c tires that are designed specifically for their larger wheels. These tires are typically thinner than 27-inch tires and offer better traction on smooth surfaces like pavement or concrete. They’re also more durable and can handle higher speeds without wearing down as quickly.

Final Words | 700c Vs 27 Inch Bike Tires

The debate between 700c vs 27 inch bike tires ultimately comes down to personal preference and the bike’s intended use. While 700c tires may offer better speed and a smoother ride on paved roads, 27-inch tires may be more suitable for off-road terrain and heavier loads. It’s important for riders to consider their own riding style and needs before deciding which tire size to choose. Both options have their advantages and disadvantages, so it’s up to the individual rider to decide what works best for them. So, whether you’re a casual cyclist or a serious competitor, make sure to choose the right tire size for your specific needs and enjoy every ride with confidence.
