Bridgestone Tyre, Symmetrical?

Good question. I assume you are wondering about the word "Bridgestone" molded on the tires.

Are the registration pins and recepticals concentric or off set? 

I'll go and check my kit. I'll get back to you in a while.

I checked my kit tires and I see why you are asking, they can be glued together either way. 

My assumption would be that they are opposite for concentric weight on an object that is designed to rotate. 

Thanks a lot for replying. I glued two tyres together without noticing this, then I started this topic. One of the tyres have "Bridgestone" molded on the same side, one is inverted.

So, you are saying that they are randomly placed? It does not seem to make sense, aren't tyres molded at once? How can they be placed differently?

I don't actually know if the brand name is molded on both sides but if they are then they are probably on opposite ends of each other, meaning one on 'top' on one side and 'bottom' on the other side. 

This is just my speculation based on equal weight distribution for a spinning tire.

Tires are injection molded like plastic model parts. The brand name as well as max psi (metric), etc. is engraved in the rigid mold where ever the mfr wants it to be.

no worries 

Without seeing the kit tires(tyres) for conformation it might be that you are trying to glue two (2) "front" halves together and will find you have four (4) parts with no markings on them. To answer the manufacturing part of your question yes tires are molded by injecting rubber into a sealed mold. The molded lettering is opposite for balancing, it looks upsidedown and backwards until you face it curbside. Hope this helps.

Even if I cannot see why it would cause balance issues (a couple of grams only), I suppose it is the right way to go. By the way; it is impossible to glue same parts together.

No problem, great question. Hopefully you continue to ask because we never learn anything until we ask. No such thing as a silly modelling question around here. Happy modelling.

Thanks for your good wishes. One last question; do you suggest priming the tyres which have very small letterings?

Armornut, This is the kit that Haptesthai is building:

The 12 tire halves are all identical on the outside but 6 have pins and the other 6 have recepticals for the pins. In the picture it is difficult to see the words BRIDGESTONE on them but they are molded there. When you put A1 to A19, they can be glued together in two options of same on both sides or 180º rotated. 

Hey Haptesthai, did you glue them all together yet? I looked around at my coworker's POVs today and all the tires, including on my car, were molded opposite (180º) on each side. Including a Michelin tire. However, I looked at two different Bridgestone tires on two different POVs and they were, yup you guessed it, the SAME on both sides. 

None of these were military vehicles but that info may get you closer to accuracy anyway. 

Cool rig, thanks for the link Sprue. My thinking was of some of the Italeri kits which have tires molded in plastic instead of the rubber/ vinyl most of the newer kit have. I did not want to confuse the topic by trying to explain balancing as it really makes no difference on a scale model. I may have to pick up one of those little six wheeled jobbies, not in to modern Japanese armored vehicles but it is cool. Now I understand the confusion, reread your post. Happy modelling.

Sprue and armor; thanks a lot. Was not expecting that many people would be interested when starting the discussion. I glued all of the tyres except for one with markings on opposite sides. I used Tamiya Extra Thin; and the only wrong tire seems unbreakable, I don't want to apply too much pressure for fear of damaging the pins. Time to use my dearest friend; my modeler's knife. 

You've helped me a lot. (a young, inexperienced modeler) It's a great community here.

Your welcome, you can prime the tyres if you like however if your going to paint them a very dark color or black a primer in my experience wouldn't make much difference. If you want the lettering to stand out try dry brushing the letters after your base coat has dried. Take a little paint on your brush, wipe it back and forth on a paper towel until it is almost dry then gently brush the raised letter area of your tyre and pop there you have it. It does take a little practice but really is simple once you get the hang of it.
