Can anyone hypothesize why there's no sidewall on these? Anything I come up with in my own mind I end up defeating.
Unrelated:
> max load of 1102 pounds.
I have to assume this is per tire considering the Chevy Bolt weighs 3,600lbs but it's not clear from the article.
- mensetmanusman 7y agoI’m guessing weight. The added inertia would provide more shear stress in the rubber to get the tire accelerating. That could have a lifetime affect due to crazing in the polymer/fiber network (which can be especially prone to failure due to interfacial failure between the solid fibers and polymer matrix).
- martin_henk 7y agoi don't know why, but adding a wall seems like stiffening the whole wheel. secondly, manufacturing the same thing with walls seem kind of impossible.
- elliekelly 7y agoI’m guessing because a sidewall on the tire wouldn’t be “airless”? And they’d have to check/monitor the air pressure of each of the “pockets” of air as temperature changes? Full disclosure: I say this as someone who knows next to nothing about tires/tire pressure/cars in general. My tire pressure light has been on for at least three months now.
- jfk13 7y ago> My tire pressure light has been on for at least three months now. Maybe worth getting that checked?
- elliekelly 7y agoIndeed, I'm told it's a sensor malfunction not the tire pressure. Apparently it's a known issue with Toyotas. The mechanic is nice enough to check the pressure for me when he sees me getting gas since the "new" sensor (sensors?) didn't keep the light off very long.

From https://www.theaa.com/driving-advice/safety/tyre-pressures https://www.theaa.com/driving-advice/safety/tyre-pressures "Under inflated tyres will increase stopping distances and affect your vehicle’s handling so that collisions are more likely; Under inflated tyres will flex more and get hotter, making sudden tyre failure – blowouts – more likely; Under or over inflation increases tyre wear so you’ll have to buy new tyres more often; Under inflation increases your tyre’s rolling resistance which means higher fuel consumption"
- astura 7y agoPlease fill your tires, driving on under inflated tires is dangerous.
- MisterTea 7y ago> I have to assume this is per tire considering the Chevy Bolt weighs 3,600lbs but it's not clear from the article. Your assumption is correct. Tire load ratings are per tire.
- Angostura 7y agoI assumed the sidewall had been cut away simply for the marketing images to show what is going on inside. I have no doubt the real thing will have a sidewall.
- mhb 7y agoSeems likely since they will want to keep snow, ice, debris, out. But it can just be of a material to prevent that.
- jakear 7y agoArticle says “Michelin has introduced a .... [tire] that has no traditional sidewall”. So seems like it may not.
- Angostura 7y agoSeems like I'm entirely wrong. I still reckon this gimmick will go.
- smugworth 7y agoIf the tire had closed sidewalls, you'd never know someone had the new tires without obtrusive labelling. Open sidewalls market themselves, not only do you see it's a different tire, you see it's an entirely different tire design that's relatively easy to comprehend the benefit of even if you know nothing about them.
- swish_bob 7y agoI'm not clear why people are leaping directly from "no traditional sidewall" to "no sidewall". It seems pretty likely that there will be a lightweight, porous, tough and possibly flexible sidewall just to keep rocks. etc out. Otherwise you're going to pick up sand, grit and rocks constantly.
