All weather tyres - at SIP Scootershop

For all-season riders who don't stop at bad weather. These tyres are specially designed for all (except winter) seasons. Especially the modern tyres have sophisticated treads, rubber compounds and a good grip even in bad weather conditions.

What size do I need for all-weather tyres?

The tyre size required for the vehicle is entered in the vehicle documents. There you will find information on tyre width, rim diameter and speed index. Of course, you can also read the tyre mounted on the scooter from its sidewall.

What does the tyre labelling mean for all-weather tyres?

Example: 3 .50-10 59J (by inch designation)

3.50 Tyre width in inches (1 inch = 25.4 mm)
10 Rim diameter in inches
59 Load index
J Speed index

Example: 90'90-10 59J (according to current designation)

90 Tyre width in mm
90 Percentage ratio of tyre width to cross-section
10Rim diameter in inches
59 Load index
J Speed index

What is the additional information on the sidewall of all-weather tyres?

Dot number: The last 4 digits indicate the production date. Thus, for example, 4503 means 45 KW in2003
Tubeless indicates use without a tube. However, this type of tyre can be used with an inner tube without any problems.
TT: This specifically indicates the use of an inner tube!
R, rf, XL or extra load: Reinforced refers to tyres with reinforced carcasses and thus increased load capacity.

What do the load and speed indices mean?

The load index (also load index, load index or LI value) indicates the maximum load a tyre may be subjected to. The speed index (also speed index, speed category, speed class, SI value or GSY) indicates the maximum permissible speed of a tyre. The load index and speed index can be found on the side of the tyre.

Speed index











V (km/h)











Load index














Load per tyre (kg)














Example: A tyre marked 120/70-12 51L has a load capacity of 195kg at a maximum speed of 120 km/h. If the speed increases to 150 km/h, the load capacity of the tyre is reduced by 75%, in our case 146kg.
If the speed is increased to 150 km/h, the load capacity of the tyre is reduced to 75%, in our case to 146kg.

Note: SIP has favourable Rims. It is best to mount a set of winter or all-weather tyres on rims, then you can change easily and quickly when the weather conditions are right. You don't have to get your fingers dirty unnecessarily or visit a workshop to mount them.

What tyre manufacturers are there for all-weather tyres?

From the abundance of manufacturers and brands, we have built up a range that, in our opinion, combines the best manufacturers, the most sizes and the widest range of use. The manufacturers are deliberately not the cheapest noname brands, but all companies whose decades of scooter and motorbike experience come into play in the development of scooter tyres:

  • HEIDENAUMade in Germany is the name of the game at Reifenwerke HEIDENAU! They have the highest standards of production and quality. Due to the wide range of sizes and classes, Heidenau tyres are probably the most widely represented in the scooter sector. HEIDENAU is particularly strong in all-weather tyres.

  • MICHELINMICHELIN has a long history in scooter tyres. The S1 and the S83 are classics. The many years of experience in racing also benefit Michelin's modern scooter tyres. The best examples are the City Grip, which has also been used as an original equipment tyre by PIAGGIO for years.

  • PMTPMT from Italy has been producing high-quality racing tyres for scooter racing for years. Despite the high price level, it becomes clear after the first ride at the latest why PMT are worth every cent. Absolutely essential to be at the front of the pack on the race track! Whether in lap races or on the quarter mile.

  • MITASThe Slovenian tyre manufacturer MITAS is one of the leading producers of motorbike and scooter tyres in Europe and has been selling tyres worldwide for almost 100 years with great success. Even whitewall tyres come off the production line there. MITAS also offers road tyres with a good price-performance ratio and popular semislicks.

  • PIRELLIAs early as 1872, Battista Pirelli founded the PIRELLI brand, which is still one of the leading tyre brands worldwide. With the SC30 scooter tyre as original equipment on various Vespa models, PIRELLI established itself in the scooter sector. PIRELLI is one of the largest tyre manufacturers in the world.

  • KENDAKENDA was founded in 1962 as a bicycle tyre manufacturer. As a leading original equipment manufacturer for scooter manufacturers such as Peugeot and Kymco, KENDA tyres are produced under very high quality standards.

  • SHINKOThe Japanese SHINKO Company was founded in 1946. After the merger with the Korean SHIN HUNG Company, SHINKO tyres became high-impact quality tyres: manufactured with Japanese technology and superior Korean craftsmanship.

Safety first - what tread depth should I not go below for all-weather tyres?

According to the law, the tyre tread depth must be at least 1.6 mm, otherwise the tyre must be replaced. However, a tread depth of at least 1 mm is sufficient for bicycles with auxiliary motors, mopeds and light motorbikes. To make this easier to see, some tread grooves have small protrusions, the so-called TWIs = tread wear indicators. These indicate the remaining tread depth, which can vary depending on the manufacturer. A scooter rider who rides with less than 1.6 mm tread depth has fallen below the legal limit (StVZO §36: Tyres and treads, Article 2) and must expect a fine and points in the central traffic register.
If the tread depth is low, the tyre's grip decreases significantly in wet conditions. The tyres can no longer displace the water film. They lose contact with the road, and the vehicle can no longer be steered and braked. Therefore, do not wear tyres down to the legal minimum tread depth. Depending on the width of the tyres, replace them at the latest at 2 to 2.5 mm, winter tyres already at about 4 mm remaining tread depth.
