Complete wheels
- at SIP Scootershop
Tyres ready on the rim
With complete wheels, changing tyres is plug & play. SIP complete wheels are pre-mounted tyres on rims. They are available with SIP steel or SIP tubeless rims for Vespa or Lambretta scooters. The tyres are ready to ride and are also perfect as spare wheels. Some customers want to combine other tyres and rims beyond our complete wheels. We are happy to take care of this with our tyre fitting service: provided the combinations fit together.
Plug & Play mounting when changing tyres
Ideal as spare wheel on scooter or in garage
as a 2nd set of tyres for other road conditions e.g. winter/summer or sport/all-weather
What size do I need for complete wheels?
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 off the tyre mounted on the scooter from its sidewall.
What complete tyres are available at SIP Scootershop?
There are scooter tyres for almost every application. We have tried to divide the different complete wheels into classes. We distinguish:
Classic tyres: These all-season tyres make the look of a classic car perfect! The classic honeycomb tread not only has a nostalgic look, but definitely also a good grip. These profiles usually have a long history or are based on it. The stars here are the MICHELIN S83, the CONTINENTAL Classic, the PIRELLI SC30 and the SIP Classic, which is unique in the segment with its approval for speeds of up to 150 km/h.
Whitewall tyres: Similar to the Classic tyres, the whitewall tyres also contribute to the retro look of the scooter. The flair of the 50s and 60s is palpable here. Whitewall tyres are not only available with the classic tread, but some also have a sportier or all-weather tread. Only a few manufacturers have mastered the art of ensuring that a whitewall tyre does not turn yellow in the sun. CONTINENTAL is the leader in whitewall tyres. But KENDA, MITAS, SHINKO and CST are also popular.
All-weather tyres: 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 profiles and rubber compounds and have a good grip even in bad weather conditions. Our tip for everyday vehicles. Germans have experience with bad weather: HEIDENAU supplies with the K58, the K47 and the K66 the most popular all-weather tyres besides the MICHELIN City Grip.
Sport tyres: An absolute must for the sporty rider. The slightly softer compound compared to the classic or all-weather tyres gives the sports tyre an incredible grip on the road. Especially nice on tours when the next serpentine is calling! Tuned engines often need tyres with a higher speed index. Our most popular sports tyres are the SIP Performer, the HEIDENAU K80 and the evergreen MICHELIN S1.
Race tyres: As slick or with semi-slick tread, these are best suited for races on dry tracks. Ideal for lap races or quarter mile races. For rainy days, there are also Racing-Rain tyres, which offer the best properties on wet tracks with their tread. Most race tyres are not homologated for normal road use. PMT is the first port of call here. But also the HEIDENAU K61 and the MITAS MC 35 make most racers' hearts beat faster.
Winter tyres: For all those who cannot do without scooter rides even in winter, we have a wide range of winter tyres from various manufacturers and in a wide variety of sizes in stock. Optimal traction and lateral guidance in snow and high drainage in wet conditions characterise these tyres. HEIDENAU and IRC are strongly represented here.
Cross tyres: Rough off-road tyres that make a trip with the cross scooter into uneven terrain perfect. For optimal grip, there are different tread requirements depending on the terrain.
What does the tyre labelling mean for complete tyres?
Example: 3 .50-10 59J (by inch designation)
3.50 Tyre width in inches (1 inch = 25.4mm)
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 do the additional indications on the sidewalls of the complete tyres mean?
Dot number: The last 4 digits indicate the production date. Thus, for example, 4503 means 45KWin2003
TL: 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 does the load and speed index 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 | J | K | L | M | N | O | P | Q | R | S |
V (km/h) | 100 | 110 | 120 | 130 | 130 | 140 | 150 | 160 | 170 | 180 |
Table part 1
Load index | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 |
Load per tyre (kg) | 136 | 140 | 145 | 150 | 155 | 160 | 165 | 170 | 175 | 180 |
Table Part 2
Load Index | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 |
Load per tyre (kg) | 185 | 190 | 195 | 200 | 206 | 112 | 218 | 224 | 230 |
Example: A tyre marked 120/70-12 51L has a load capacity of 195 kg 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 146 kg.
If the speed increases to 150 km/h, the load capacity of the tyre is reduced to 75 %, in our case to 146 kg.
Safety first - what tread depth should I keep?
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.
