XXIII. Żuk A06 wheels: tyres wear, alternatives to standard rims and spare placement

Tyres wear and wheels rotation

Removing wheels, I noticed some uneven wear. It was not a big surprise since I’m expecting a full replacements of plastics parts of the front suspension.

It is interesting to learn (Żuk Budowa, eksploatacja, naprawa) that it is not by design per se but almost. During maintainance (9000 km), they actually recommend a switch of wheels according to this view (from top):

If this advice is to be followed, directional tyres are not an option. Even if not specifically convenient, it is probably good practice for this vehicule, with benefit of not letting the spare wheel unused.

Rims alternatives

Standard Żuk’s rim are a no go to fit modern tyres. I’m not set exactly on which tyres I’ll install but it will likely to be 205/75 R16C (or 205/80R16), it’ll require at rims from 6 to 7″ width, for 16″ ø and 5×139.7 bolt spacing.

Some people fits UAZ/Suzuki large off-road rims:

I do not want rims that different from the original. Łada Niva are much more similar and fit the bill.

I bought a set of 4 Łada Niva rims (280 zł) + 1 spare (99 zł).

+ kosztuje = 379 zł = 88 €.

felgi stalowe = metal rim
średnica felgi =  rim ø (ex: 16″)
szerokość opony =  tyre width (ex: 205)
szerokość felgi: = rim width (ex: 6.0″)
rozstaw śrub = bolt spacing (ex: 5×139.7)
ciśnienie powiertrza w oguniemiu = tyre air pressure

 UPDATE: Niva rims could either be tubetype or tubeless, tubeless being available apparently only since the 2000’s. I am afraid I got the wrong ones. It is not an urgent matter but another option will have to be thought about. Probably toward either getting Niva tubeless recent rims or Lublin 16″ rimes that are tubeless.

For the record, factory tyre pressure is 3,2 bar front and 2,5 bars rear.

I’ll buy tyres only when the Żuk will be ready to go, since there is no point in buying early hardware that actually degrades over time, even more when not being used enough.

Nonetheless, I checked what is on the market. As of today, in decreasing order of preference, I’d probably take Continental ContiVanContact 200 205/75 R16 110/108 R C (B fuel consumption, A brakes, 72dB) or Pirelli Carrier 205/75 R16 110/108 R C (C, A, 71dB) or much cheaper Nexen Roadian CT8 205/75 R16 113/111 R C (C, A, 70dB).

Spare wheel placement

By default, spare wheel is installed under the chassis:

It is generally a good idea: it does not waste space in the cabin, it is not easily accessible to thieves, the weight is properly balanced. This location could be, however, useful to install a water tank and an used water/waste tank.

I noticed alternatives over the web:

Noone tried to put the wheel on the front, like on VW van (rear fitted engine): anything in front of the radiator is an obvious no go.

Over the exhaust is doable on dropside truck. However practical, it seems anyway an incredibly terrible idea to expose the tyre to heat, not to mention it does not seem convenient to remove/put back in the spare.

On the roof has the advantage of not being prone to thievery. But I’m just not a fan of adding more weight on top of vehicule that has already high center of gravity. Plus putting up and down the wheel(s) might not always be easy and we know now that it is best to often move around wheels to spread evenly the wear.

The Źuk Grzmiący Rydwan A07 back door placement  is quite nice. Easy access, nothing altered – except the door support. Obviously this work almost out of the box  due to Źuk A07 back door being in one piece.

On a Źuk A07’s two-pieces back door, similar placement would prevent opening the top door.

I consider anyway having the bottom door to be always closed in camper-mode so it is ok for me to condemn it. Putting the spare wheel to the left would hide half of the anti-fog light (not good) and plate. Putting it in the middle would completely hide the plate.

Car plate could be moved. It is not completely allowed but should not be a massive issue if done cleanly and according to the rules.  So what are the rules? In France (since, in the end, that is where we plan to register the Źuk) it is as follows:

Conditions générales de pose.

Chacune des plaques d’immatriculation est constituée par une pièce rigide rapportée, fixée au châssis ou à la carrosserie du véhicule d’une manière inamovible.
Si le véhicule dispose d’un emplacement pour la pose de la plaque d’immatriculation, au sens de la directive 70/222/CEE ou 74/151/CEE ou 93/94/CE susvisée, la plaque d’immatriculation est fixée à cet emplacement, lui même pourvu de l’éclaireur de plaque visé à l’article R. 313-12 du code de la route.
Si le véhicule ne dispose pas d’un emplacement spécifique pour la pose de la plaque d’immatriculation, la plaque est fixée suivant les dispositions :
― du paragraphe 2 de l’annexe à la directive 70/222/CEE susvisée pour les véhicules des catégories internationales M, N et O ;
― du paragraphe 2 de l’annexe II à la directive 74/151/CEE susvisée pour les véhicules des catégories internationales T, R et S ;
― du paragraphe 2 de l’annexe à la directive 93/94/CE susvisée pour les véhicules de la catégorie internationale L,
suivant les définitions de l’article R. 311-1 du code de la route.
Les éléments de fixation des plaques d’immatriculation doivent être de la même couleur que celle de la zone sur laquelle ils sont apposés.

The idea is to follow 70/222/CEE paragraph 2 (Źuk being CEE N1 category) as if there was no existing emplacement. What does this paragraph says?

2. LOCATION OF THE SPACE FOR MOUNTING AND THE FIXING OF PLATES The space for mounting shall be such that after correct fixing, the plates shall have the following characteristics:

2.1. Position of the plate in relation to the longitudinal axis of the vehicle

The centre point of the plate may not be situated to the right of the longitudinal plane of symmetry of the vehicle.

The left-hand edge of the plate may not be situated to the left of the vertical plane which is parallel to the longitudinal plane of symmetry and touches the extreme outer edge of the vehicle.

2.2. Position of the plate in relation to the longitudinal plane of symmetry of the vehicle

The plate shall be perpendicular, or practically perpendicular, to the longitudinal plane of symmetry of the vehicle.

2.3. Position of the plate in relation to the vertical plane

The plate shall be vertical subject to a tolerance of 5º. Where the shape of the vehicle so requires, however, it may be inclined to the vertical: 2.3.1. at not more than 30º when the surface bearing the registration number faces upwards, provided that the height of the upper edge of the plate is not more than 1.20 metres from the ground;

2.3.2. at not more than 15º when the surface bearing the registration number faces downwards, provided that the height of the upper edge of the plate is more than 1.20 metres from the ground.

2.4. Height of the plate from the ground

The height of the lower edge of the plate from the ground shall not be less than 0.30 metres ; the height of the upper edge of the plate from the ground shall not be more than 1.20 metres. However, where it is impossible in practice to comply with this latter provision, the height may exceed 1.20 metres but it must then be as close to that limit as the constructional characteristics of the vehicle allow and must in no case exceed 2 metres.

2.5. Geometrical requirements regarding visibility

The plate shall be visible in the whole space included within the following four planes, viz : the two vertical planes touching the two lateral edges of the plate and forming an angle measured outwards of 30º with the longitudinal median of the vehicle ; the plane touching the upper edge of the plate and forming an angle measured upwards of 15º with the horizontal ; the horizontal plane through the lower edge of the plate (however, if the height of the upper edge of the plate from the ground is greater than 1.20 metres, this latter plane shall form an angle measured downwards of 15º with the horizontal).

2.6. Determination of the height of the plate from the ground

The heights given in 2.3, 2.4 and 2.5 shall be measured with the vehicle unladen.

As far I understand, a two-line plate placed as follow should be ok, probably mounted on a specific plate support:testfinal.jpg

As for thieves, I though it could be cheap and easy to come up, instead of just inside support plate with 5 bolts to which is attached the wheel and some anti-theft nut (that I’d like to avoid), to actually have also on the outside a bar with two bolt weld and only 3 bolt from the inside support. Having all bolts inside would be best in matter of security but would make the wheel annoying to install/remove.

Such setup would require only a small metal plate, a decently large U bar, a tube and some bolts.

+ kosztuje = 88 € ; Żukventure cost so far = 1124 + 88 = 1212  €
