I've read on InsideEVs' forums that European tire vendors provide efficiency ratings for the tires they sell. Does each European tire vendor who provides tire efficiency ratings conduct their own testing or do they display ratings from an independent organization? How hard would it be for US tire vendors to provide this information? Tire Rack has a page that claims, "Thankfully, there is an EV tire for nearly every driving style and condition." However, it doesn't say anything about comparing efficiency on that page.
I gave up on getting independent, tire rolling resistance. My last attempt with EU brands failed to find US equivalents. Bob Wilson
They are a new brand, owned by Sailun, and just launching in 2023, so they've just been working on creating brand recognition ahead of actually shipping tires. Should happen soon, though. Hankook also has an EV-specific line called Ion, with a winter tread. Not sure about availability of those yet - I just stumbled across them last week.
Nokian tires are rated for EVs, and I'm driving on Hakkapeliitta R3 winter tires which have minimal impact on range. I really like them.
Just had a look and the Hakkapeliitta R5 is specifically for EVs. This is good to know because this is the winter tire I trust the most.
From my Prius days, I had been using Bridgestone and before Sumitomo. But Bridgestone dropped the ECOPIA tires in my size. Good to know about ERANGE and explains why I can't order them. Bob Wilson
Hey Dom. I bet you need good winter tires in Tallahassee. I've seen videos on Kyle's channel with his model 3 and Nokian tires and they performed well in deep snow. I use the studded R10's on my vehicle.
Yeah, no need for snow tires down here, but I am from Canada and I know how big a difference good snow tires make.
Luckily in my case, that would be the difference of not having to take the bus 2-3 days a year, but you are absolutely correct for the rest of the country
To get US tyre vendors to provide this information, a law would be required. Without a law, they can use vague marketing bullcrap to describe their tyres. Hard numbers are absolute evil to marketing departments. Many US market tyres are also available in Europe. Those ones, you can get the labels. For non European market ones, you are not getting numbers. My WR G4 are US market only, so no label. Hakkas are worldwide, so there are labels. Anecdotally, I felt the wr-g4s on my R53 were lower rolling resistance than my 'C' rated summers. On my SE, they seem close to the A rated Hankooks. I believe consumer reports have been doing rolling resistance tests.
“Evo 3 feels better” For something that can be quantifiable measured, that’s pretty sad. Sent from my iPhone using Inside EVs
In the unlikely case my meager photoshopping skills deceived anyone, let me say I wrote that comment into the Rolling resistance column.
