More Details on the BMW i3 Bridgestone Ologic Tire Technology

MAR 30 2014 BY TOM MOLOUGHNEY 14

Much has been made about the tall narrow tires on the BMW i3. They are really unlike any tire on any other car currently in production and they certainly don’t look like they belong on a BMW. However BMW and Bridgestone did their homework on this, and accomplished the goals they set out to. That was to develop a tire that is not only efficient, but also delivers the performance expected of any BMW.

How did they do it? Ologic technology. Yep, they developed something so new and advanced you have never even heard of it before! So while I as the Geneva Motor Show a few weeks ago, I made it a point to stop by the Bridgestone exhibit to ask about this new mysterious “Ologic Tech”. As I approached the Bridgestone area, I could see they had a Capparis White i3 on display with it all lettered up promoting this new Ologic technology, and they even had an award in a case next to it that proudly displayed that Bridgestone won the 2014 Tire Technology International award for Tire Technology of the year! Fantastic! I was even more pumped up to find out what this new Ologic technology was. Could it be a new special rubber compound or tread pattern? I was about to find out.

So after asking the information desk for someone to interview I was introduced to a Brigestone product manager to answer my questions. I didn’t waste any time. My first question was: What exactly is Ologic technology? I don’t have the exact words he used but to paraphrase he basically said “Ologic Technology is our way of creating an efficient tire that still offers optimum performance. By using a very tall narrow tire we simultaneously reduce drag, rolling resistance and tire deformation. The height of the tire in relation to the width also increases the contact patch which allows for retain the dynamic driving characteristics of a much wider tire” So Ologic is just a name of a concept, not any specific rubber compound or such? Yes. Alright well that was a little let down because I figured I was going to get a lesson on rubber or tread or something other than what I heard.

So why are they so special? They must have done something right to win the Tire Technology of the Year award, no? Here is an excerpt of how Bridgestone explains why these are indeed special:

A Unique Concept for a Unique Car

BMW has achieved a genuine milestone with the i3 electric car. Doing justice to its unprecedented levels of both efficiency and performance demanded more than just a new tyre but an entire new tyre concept. Bridgestone’s answer came in the form of the ologic technology, which capitalises on the synergies of a large diameter coupled with a narrow tread design. The result is a tyre that delivers significant improvements in aerodynamics and rolling resistance, while still offering outstanding grip in wet weather conditions.

Combining a large diameter with a narrow tread pattern has several advantages. While the tread on smaller diameter tyres is typically inclined to excessive movement or “deformation” during driving, the larger diameter and higher belt tension significantly reduce tyre deformation and therefore conserve energy that is otherwise lost through internal friction which helps to reduce rolling resistance. By the same token, the narrow tread concept improves aerodynamics. The most spectacular achievement, however is that these improvements do not involve a trade-off in terms of safety. The tyre’s long contact patch (relative to its narrow width), revolutionary tread design and compound still ensure outstanding grip in both wet and dry conditions.

They have obviously done something right because even though they look like they would be better suited on a motorcycle, the i3 handles exceptionally with them. I’ve spoken to quite a few people now that have had an i3 on a race track and all of them were genuinely surprised at how well the car performed. In a few weeks I should be taking delivery of my i3 and I can the really put the “Ologic Technology” to the test.

EV tires are going after efficiency. For most this is desirable. For myself living in the southern US this would be the perfect tire. I am guessing that it’s weakness will be snow traction. To that I say, you can’t have it all. For the most part, people favor a universal tire that does a little bit of everything. This one sounds more specific and again the one that I would choose if given a choice. I am betting if this technology takes off, and I believe it will, that more cold climate drivers will own two set of rims and two set of tires for seasonal perfection.

Snow tires are generally slimmer, as you want then to cut through the snow rather than float on top. Looks like they also have winter versions with more stiping that will help grip ice and hard snow. I would think these would be perfect winter tires, the only upgrade would be studded version in the future.

At scale, my lawnmower has similar tires. 😉

The Ford Model T, and Citroen 2CV were the most popular cars ever made…built in huge numbers. They both had tall, narrow tires. Hopefully, this again become the norm.

Disappointed

Yes, if you but a BMW i3, you will be returning to the days of the model “T”!

The difference is that in it’s day, you could buy the model “T”, for $260 (Oct 2024).
Today, you won’t be able to purchase one of these new tires for $260.

Disappointed

Ooooops, that Model “T” was $260, in 1924!

Keep that comment. Maybe in 2024, Tesla will introduce the model T.

Back on topic: Those tires are likely to be more than $260 each. Even at $260, that’s $1040 for a new set of tires, not including balancing, installation, TPMS, road hazard, etc. No thank you. That’s over 13 months of car payments for my i-MiEV.

You and I have the same fear. If you have to spend triple on the cost of tires that negates your gas savings. One supplier of tires makes me think that the cost will never come down either. Does anybody remember the SVO Mustangs with TRX tires of the eightys

This does not look like a new concept:

Hopefully they don’t have the sidewall blowout issues that the low rolling resistance Goodyear’s that come with the Volt suffer from.

Wish the dealers would have but protected me from that fiasco. Instead, they gouged me…twice

I know someone who works at a BMW dealership, and I’m hoping to find out the price of these tires and wheels. I would love to buy some to use on my CarBEN prototype.

Tall narrow tires have a smaller frontal area, which make the aero drag much lower. These tires are the first/only high efficiency tires made commercially for EV’s that I’m aware of.

mindmachine

According to my BMW dealer, these tires are only around $60 each or $240 for a set of 4.
