Tyre load index & speed rating
Understand what tyre load index and speed ratings mean, how they affect safety, and how to choose the right tyres for your Motion Rental scooter.
-
The speed rating is the maximum speed a tyre is designed to handle safely.
-
The load index is the maximum weight a tyre can safely carry.
-
For safety and insurance, always match or exceed the ratings in your scooter manual or on the original tyres.
-
Example:
100/80-12 56J→ 56 = 224 kg per tyre, J = 100 km/h. -
Using tyres with a lower rating than required can compromise safety and may breach your rental agreement.
Tyre speed rating (definition)
The tyre speed rating is a letter on the tyre sidewall that shows the maximum speed the tyre can safely handle when it is correctly inflated and carrying its rated load.
Manufacturers test tyres under controlled conditions, then assign a speed symbol like J, L, M, T, or H. This symbol links to a specific maximum speed in km/h.
The speed rating does not mean you should ride at that speed. It is an upper safety limit for the tyre, not a target speed.
Common speed ratings for scooters and light vehicles
Scooters and small motorcycles usually use lower speed ratings than cars, but they still must match what the scooter manufacturer specifies.
Some common speed ratings you may see:
-
J – up to 100 km/h (very common on smaller scooters)
-
L – up to 120 km/h
-
M – up to 130 km/h
-
P – up to 150 km/h
-
Q – up to 160 km/h
-
R – up to 170 km/h
-
S – up to 180 km/h
-
T – up to 190 km/h
-
H – up to 210 km/h
Choosing the right speed rating
Always choose a tyre with a speed rating that meets or exceeds the rating in your scooter manual or on the original tyres.
-
If the manual or original tyre says J (100 km/h), you can use J, L, M, P, T, H, etc.
-
Do not fit a tyre with a lower speed rating than specified (for example, using J when the manual requires L).
Riding on tyres with a too-low speed rating increases the risk of overheating, rapid wear, or failure at normal road speeds.
If you fit tyres with a lower speed rating than required, you may be in breach of your rental agreement and at higher risk of a tyre failure.

Tyre load index (definition)
The tyre load index is a number on the sidewall that shows the maximum weight the tyre can safely carry at its rated pressure and speed.
You will usually find it right before the speed rating letter, for example 56J, where 56 is the load index and J is the speed rating.
Each load index number maps to a specific maximum load in kilograms.
Common load index values for scooters
Here are some common load index ratings you may see on scooter tyres.
| Load index | Max load per tyre (kg) |
|---|---|
| 45 | 165 |
| 47 | 175 |
| 49 | 185 |
| 51 | 195 |
Values such as 45–51 are typical for small scooters and light motorcycles, but always check your specific scooter requirements.
Choosing the right load index
Choose a tyre with a load index that meets or exceeds the original tyre or scooter manual.
-
Check the front and rear tyres separately, as they may have different load indexes.
-
Remember that the rating is per tyre, so the total vehicle capacity depends on both tyres together.
If you carry a delivery bag, passenger, or heavy cargo, you rely even more on the tyre load rating. Running below the required load index increases the chance of sidewall damage, overheating, and sudden failure.

Reading the markings on your tyre
Tyre sidewall markings combine size, construction, rim diameter, load index, and speed rating in one line.
Example:
100/80-12 56J
-
100– tyre width in millimetres. -
80– aspect ratio (height as a percentage of width). -
-– construction type (often shown as-orR). -
12– rim diameter in inches. -
56– load index: 56 = 224 kg maximum load per tyre. -
J– speed rating: J = 100 km/h maximum speed.
Check both front and rear tyres, as the markings may differ.
For more detail on tyre size markings, see Tyre size.
Why it matters (safety, performance, longevity)
Using tyres with the correct load index and speed rating gives you:
-
Safety – the tyre can handle the weight of you, your gear, and the scooter at normal road speeds without overheating or failing.
-
Performance – proper ratings support better handling, braking, and stability, especially when cornering or riding in wet conditions.
-
Longevity – tyres that operate within their designed limits wear more evenly and last longer, saving you money and reducing downtime.
Riding on under-rated tyres can feel fine at low speeds but become dangerous under emergency braking, during long delivery shifts, or when carrying extra load.
Our recommendation
-
Match the load index and speed rating on your existing Motion Rental tyres or in the scooter manual.
-
If you change brands, choose tyres with equal or higher ratings, never lower.
-
If you are unsure what to choose, contact the Motion Rental team before fitting new tyres.
Correct tyres protect you, your passengers, other road users, and your rental coverage.
Final notes
Tyres are part of your safety equipment and your rental conditions.
If you fit tyres with a lower load index or speed rating than required:
-
You increase the risk of a tyre failure.
-
You may be in breach of your rental agreement.
-
Damage or incidents caused by incorrect tyres may not be covered.
If you have already changed tyres and are not sure about the ratings, check the sidewall markings now and reach out to us if anything looks different from the original tyres.
FAQs
Yes. If you share the scooter model and a clear photo of your current tyre markings, the team can confirm suitable load index and speed ratings and help you choose replacements that meet our requirements.
In many places it is illegal or against road rules to use tyres with a lower speed rating than the original equipment, especially on public roads. Even where it is not explicitly illegal, using a lower rating reduces safety and may affect insurance and your rental agreement.
Look along the tyre sidewall for a sequence like 100/80-12 56J printed in raised letters and numbers. The number before the final letter is the load index (here 56), and the final letter is the speed rating (here J).
Yes, it is generally acceptable to use tyres with a higher load index or speed rating than specified, as long as they are the correct size and type for the scooter. Higher ratings do not give you permission to exceed speed limits; they just provide extra safety margin.
Overloading or using under-rated tyres can cause overheating, sidewall damage, or sudden tyre failure. You may feel vague handling, wobbling, or extra heat at the tyre after riding. In serious cases, the tyre can fail without much warning, especially at speed or under hard braking.
