Tires for EVs

    Hi everyone,

    My wife and I recently purchased the 2022 Ioniq 5 preferred long range edition, which we are loving! 

    We always put winter tires on our cars and are looking at our options, the dealership got an estimate for us which we found expensive. We can save about $500 by going with a local tire distributor, but they are regular rims and tires, not ones specifically designed for EVs. The rims offered by the dealership are specifically low resistance for EVs, they are called EV01 by FAST. The tires I believe are designed for EVs as well, they are Gislaved brand.

    My question is, in people's experience, is it worth paying the extra money for tires and rims designed for EVs? Will some of the additional costs be offset by better mileage and/or increased life of the tires?

    Thank you,

    Trevor Rodie

    Hi

    There is lots of tire discussion here. Get our I5 on Tuesday. Setup same day with local tire shop. Personally did not worry about winter tire range loss. Less driving and slower driving in winter. All depends on your situation.

    I'm on my third EV since early 2013 and had winter tires on all of them. I never worried about EV specific tires for winter. I figured that there are much bigger factors that impact range in the winter anyway, and the most important factor is cold weather performance.

    I should mention that when I switch back from winter tires to EV specific summer tires in the spring, I haven't been able to specifically notice an improvement in efficiency/range. I'm sure there is one, but wind and weather seem to have more of an impact which makes it hard to tell.

    I still haven't worn out the original tires on the car. When I do, I'll switch to some EV specific tires. Curious to hear if these really last longer and by how much in people's experience, but since they're so new I may have to wait years for the answer.

    Trevor,

    The rims offered by the dealership are specifically low resistance for EVs, they are called EV01 by FAST. The tires I believe are designed for EVs as well, they are Gislaved brand.

    For background, the Fast EV01+ rims are around CAD $300 each.  There are any number of good winter tires, and they range hugely in price, from about $150 to as much as $500 each.  The Gislaveds are cheaper than most at under $200 each (depending on the model).  So, as a package, balanced and mounted, you should expect to pay under $2,500, with tax.

    Winter tires are generally not "low rolling resistance" tires (and should not be), so should your rims be super efficient aero rims?  

    Aero rims are really only valuable as an efficiency aid/range extender when you are travelling fast, at highway speeds, and the faster the the better.  Are you doing long road trips in winter where traveling fast on well-maintained is possible?  If so, then maybe winter tires are not such an important safety requirement. And if not, then the rims are really wasted.

    So my view is that, for most people, standard rims, likely a bit cheaper, and the best snow tires you can find/afford, are the way to go.

    Will some of the additional costs be offset by better mileage and/or increased life of the tires?

    Winter tires are generally faster-wearing than summers, but some are better, and the choice of tire is independent of the rim choice.  More expensive aero rims, used only in winter, will lively never offer a payback in terms of electricity savings. You might save 2-3 kWhs of energy per week if you drive far and fast on aero wheels, and how long will the energy savings of maybe $1 a month take to pay for those wheels.
