Are you looking for the perfect tyre pressure for your Giant and CADEX hookless rim road wheels and compatible road tyres? Look no further! This calculator gives you the recommended tyre pressure for your bike set up and riding conditions.
Here are a few tips to keep in mind when adjusting your tyre pressure:
- Never exceed the maximum (MAX) tyre pressure indicated on the rim, the tyre or the rim tape.
- Please note that the stated MIN pressure on many current Giant tyres (e.g. 85psi for 25C tyre) was originally defined based on a durability test with a 120kg load at 1.5 times the regulated distance. CURRENTLY, for all Giant tyres this minimum (MIN) pressure can now be defined as 70 psi (4.8 bar) for 23C & 25C tyres, 50 psi (3.4 bar) for 28C tyres and 45 psi (3.1 bar) for 32C tyres. Never inflate to less than the MIN pressure.
- The above pressure values are recommended starting points only.
- Please be aware that the load limit of all Giant Road WheelSystems is 129kg. This includes the weight of the rider + bike + luggage. For your own safety, please do not exceed the load limit, and please note that it is never advisable to load the bike to its maximum capacity.
Alter your tyre pressure based on the surface you’re riding on:
Conventional road wisdom has always held that 100 psi (6.9 bar), more or less, is the magic number for speed and compliance, and on brand-new smooth pavement or at the track, your tyres could feel great inflated to that pressure. However, when riding on anything other than a perfectly smooth surface (which, if we’re honest, is what most of us ride on most of the time), we recommend taking advantage of the benefits of tubeless and hookless technology and going with 10-15 psi / 0.7-1.0 bar less than what you might have normally put in (around 85-90 psi / 5.9-6.2 bar in the case of 100 psi / 6.9 bar mentioned above, for example). This allows the tyre to conform better to imperfections in the road, reducing deflection and wasted energy as well as providing a smoother, more comfortable ride. Likewise, in wet conditions, just 10 psi / 0.7 bar less than what you usually might run will give you an increased contact patch and much better grip.
Adjust your tyre pressure according to the volume of the tyre you’re using:
90 psi / 6.2 bar could be perfect for your weight and the road surface when you’re on 25c tyres, but if you decide to swap out to wider 28c tyres, you’ll be increasing tyre volume significantly, which means if you want the same smooth and supple ride quality from your new tyre size, you’ll have to adjust air pressure downward to accommodate.
Adjust your tyre pressure based on your weight:
tyres support the weight of the rider plus the bike plus any luggage or gear; for this reason, heavier riders require more pressure and lighter riders require less. As such, it’s essential to adjust your tyre pressure according to your weight rather than try to use a “one pressure fits all” measurement (like the magic 100 psi / 6.9 bar we mention above!).
Never inflate over the maximum tyre pressure indicated on the rim, the tyre and /or the rim tape:
To make sure every ride is safe, Giant provides a recommended maximum (MAX) tyre pressure, indicated either on the rim, the tyre or the rim tape. You should never inflate your tyre beyond that pressure.
Maximum tyre pressure is NOT the recommended tyre pressure:
To make sure every ride is great, Giant recommends that you never inflate your tyres up to the maximum pressure either. Inflating to maximum pressure is unnecessary and for the reasons discussed above can give a harsh, unpleasant and potentially dangerous ride experience. Instead, Giant recommends following the inflation advice and pressure guide presented here.
Check your tyre pressure before every ride:
This goes all the way back to the beginning: Appropriately inflated tyres conform better to imperfections in the road, absorbing impacts and allowing you to ride more efficiently and safely with more comfort and control. A one minute pressure check before each ride to ensure your tyres are appropriately inflated can make the all the difference! Not only will you be able to ride with more confidence, but you’ll also enjoy a smoother, more comfortable ride.
Maintaining optimal tyre pressure on your Giant bicycle is essential for achieving maximum performance and a comfortable ride. Giant bicycles are designed to perform at their best when their tyres are inflated to the correct pressure, so it’s important to check your tyre pressure to ensure it’s properly inflated.
Correct tyre pressure on Giant bicycles is essential for providing maximum performance and a smooth ride. Higher pressure in your tyres increases rolling resistance. This has an effect on speed, as well as making for a harsher ride over rougher surfaces. Conversely, lower pressure can cause the tyres to flex more when cornering which may feel unstable, and can also lead to a greater chance of punctures due to the tyres being more prone to contact with the ground.
The correct tyre pressure for Giant bicycles is dependent on the model and size of bike, tyre size and rider’s weight. It is usually printed on the tyre and/or in the manual of your bike. Generally, a higher inflation pressure is required for faster, smoother riding while lower pressure can be used for increased comfort on roads and paths. Ideally, you should use a hand pump with a gauge to ensure you’re achieving the best pressure as some hand pumps are not accurate and can lead to overinflating your tyres.
Now that you know how to properly inflate your tyres on Giant bicycles, here are a few tips to help you maintain optimal tyre pressure:
● Check your tyre pressure regularly, especially before long rides.
● Regularly clean your rims and tyres of dirt and debris. This will ensure the surface is smooth and provides better contact to the ground which can minimise excessive tyre slippage.
● Make sure to use sealant inside your tyres to guard against punctures.
By following these steps, you’ll ensure that your Giant bicycle is running at its best and ready to take on whatever terrain you choose to ride.
