After 5,000 Miles, Kia EV9 Proprietor Says His Kumho “EV Tires” Are Sporting Out Quick Whereas His Ford Mustang Mach-E’s Cheaper Excessive-Load Tires “Look Model New,” Calling the EV Tire Premium a “$700 Racket With Zero Noise or Vary Profit”

Spend any time in an EV9 house owners group, whether or not within the ready lounge at a Kia service division or scrolling by means of social media on a Tuesday night time, and you’ll finally hear the identical query rise above the hum of kilowatts and cost charges. What precisely are you paying for if you purchase EV-specific tires? The advertising is obvious. Further vary, further quiet, purpose-built for heavy, high-torque electrical machines. The tales from house owners tending actual autos in actual locations are much less tidy. A kind of tales belongs to Jeff Bader, and it begins with a easy A/B check between the Kia EV9 in his driveway and the Ford Mustang Mach-E parked subsequent to it.

“So I did a bit experiment with tires. When the tires wanted to get replaced on the EV9, I purchased the very same Kumho EV tires that had been on it, and my Mach-E additionally wanted new tires. I purchased commonplace higher-load tires (non-EV) to see if I might discover a distinction. I checked out three components: tread life, noise, and vary.

EV tires are touted to have an additional noise-reducing layer inside them as a result of there is no such thing as a engine noise to drown out the highway noise on commonplace tires, and the EV tires are additionally marketed to enhance vary between expenses over a regular tire.

I put in the Kumho tires on the EV9 round July 4, 2025, and I had the usual tires put in on my Mach-E the identical week. After virtually 4 months and 5,000 miles of use on the EV9 and 4,000 miles on the Mach-E, listed below are my conclusions.

I name BS on the EV tire racket. I used to put in tires (mounting and balancing) many moons in the past, and I observed zero variations between the EV tires and common tires when doing a visible inspection. The additional sound absorber that ought to have been on the within of the tire (based mostly on movies I watched and illustrations within the movies)? I noticed zero proof that there’s something completely different within the EV tire expertise.

They cost a crapton more cash for a similar tires and simply put an EV label on them.

Noise: I observed zero distinction in noise ranges in my Mach-E after switching to a regular tire. In actual fact, the usual tires had been quieter than the EV tires I eliminated (most likely as a result of they had been worn out and I wanted an alignment).

Experience: The non-EV tires are easy and deal with higher than the tires I eliminated. I anticipated this to occur as a result of, once more, the outdated ones had been worn out; nonetheless, the brand new tires trip higher than my outdated ones did at any time through the 16k miles I drove them earlier than making the change.

Vary: If there’s a distinction right here, I’ve not observed it. That is affected by the seasons and out of doors temperature anyway, so it’s not possible to inform for positive, however I by no means actually noticed any drop-off in vary that I used to be anticipating. Not scientific in any respect, simply my commentary.

Tread life: The Kumho tires on the EV9 are considerably worn after simply 5,000 miles. The rear tires are worn far more than the entrance tires (I’ve an AWD Land mannequin, however I do know the RWD engages far more usually than the entrance drive). I’ll probably get about 15k miles or much less from these tires (we obtained 16k+ from the primary set).

The tires on the Mach-E look model new. I used to be anticipating them to have proven extra put on up so far, however they haven’t. I’ve not taken any measurements, however they nonetheless look new.

I simply had the EV9 tires rotated, and the dealership tried telling me the tires must be changed. They’re smoking some low cost crack, and so they declare the rear tires had been right down to 4/32 of tread. I discover this tough to imagine at this level, however they’re undoubtedly worn greater than anticipated.

My conclusion is that if you’re going to spend money on tires, don’t let the gross sales pitch of shopping for an EV tire at $500–700 extra per set, as a result of they’re “particular tires for EVs”, idiot you. Purchase a superb set of high-load tires as an alternative, and don’t fear about greater noise ranges and shorter vary, as a result of you’ll probably by no means discover the distinction anyway.”

Strip away the Fb formatting noise, and what stays is a tidy little driveway experiment. Similar family, two trendy EVs, one on EV-branded Kumho rubber and one on non-EV high-load tires. Jeff appears to be like at three issues any proprietor cares about greater than brochure copy. Highway noise, vary, and tread life. 

Kia EV9: Electrical Tires & Grip vs. Effectivity

• The EV9’s EV-specific tires are constructed to deal with its substantial weight and torque, utilizing bolstered buildings and specialised rubber compounds to take care of stability with out losing vitality.
• These tires scale back rolling resistance by utilizing lower-grip compounds and streamlined tread patterns, extending the EV9’s driving vary in contrast with conventional higher-grip tires.
• EV9-optimized tires are engineered to remain cooler underneath heavy masses, bettering effectivity throughout acceleration and freeway cruising.
• In contrast with efficiency tires, EV-specific designs commerce some cornering chew and supreme grip for quietness, sturdiness, and most vary effectivity.

In his expertise, the EV9 eats its EV tires shortly and doesn’t appear quieter or extra environment friendly due to them, whereas the Mach-E on typical high-load tires feels smoother, quieter, and appears virtually untouched after a couple of thousand miles. His language is colourful, his conclusion blunt, however the core grievance is simple. He doesn’t really feel he’s getting a transparent, measurable profit that justifies a premium of 5 to seven hundred {dollars} per set.

On one aspect, you could have Rick Isenberg, who reminds everybody that subjective impressions will not be the identical as managed testing. He notes that some EV tires actually are constructed with completely different compounds and constructions geared toward decrease rolling resistance and, in sure fashions, further sound deadening contained in the carcass. A few p.c enchancment in effectivity is just not one thing most drivers can see with out instrumentation, but it’s the form of incremental achieve that reveals up in formal exams from organizations like Shopper Experiences and the U.S. Division of Power over giant information units (Supply: Shopper Experiences, “EV Tires Defined,” 2023; U.S. Division of Power, Car Applied sciences Workplace, 2022). From that vantage level, the EV label represents actual engineering decisions, not only a sticker.

On the opposite aspect, Jeff stays unconvinced. He has his palms on the tires, his bank card on the counter, and Western Pennsylvania underneath the tread. He sees speedy put on on the rear axle of an All Wheel Drive EV9 that weighs north of 6,000 kilos, and he sees a Mach-E on commonplace high-load tires that seems barely damaged in. To him, precise possession expertise issues greater than any chart. Then there may be Brian Sherwood, who calmly studies roughly 35,000 miles out of his unique Kumhos on a 2024 Mild Lengthy Vary EV9 earlier than switching to Michelin Defender 2 tires, with no apparent change in noise or vary. Brian’s end result stands in stark distinction to Jeff’s 15,000-mile expectation and is a reminder that geography, highway floor, alignment settings, and driving fashion can multiply or divide tread life all by themselves.

Heather Liberadzki provides one more voice, planning forward to suit non-EV all-season tires on her GT-Line when the originals are spent and estimating she will be able to coax maybe one other 5,000 miles from the manufacturing unit set if she behaves with the accelerator. Her place is just not anti-EV and definitely not anti-Kia. It’s sensible. If high-quality, high-load tires ship acceptable noise, grip, and vary at a decrease price and with longer life, they’re price critical consideration. Taken collectively, the thread feels much less like a revolt and extra like a maturing proprietor neighborhood beginning to query whether or not the EV label on a sidewall is an absolute requirement or just one choice amongst a number of for a heavy electrical SUV.

Behind the opinions sits actual physics. EVs just like the EV9 and Mach-E are heavy, torque-rich machines. They want tires with excessive load scores to hold the burden and strong building to handle immediate torque with out deforming excessively. Many EV-marketed tires chase low rolling resistance by means of stiffer tread blocks, specialised rubber blends, and narrower tread patterns, which might certainly assist prolong vary by lowering the vitality wasted because the tire flexes. The flip aspect is that a few of these designs may be extra delicate in heavy rain. A more durable compound and fewer, shallower grooves can, in sure patterns, evacuate water much less successfully at freeway velocity, which makes hydroplaning extra probably than on an aggressively siped, softer compound tire. That doesn’t imply EV tires are inherently unsafe. It means they’re a compromise amongst effectivity, grip, noise, and life, simply as each tire has at all times been.

The EV9 provides one other complication. Its curb weight and three-row mission imply the tire is working onerous even earlier than you pile in children, gear, and winter climate. It completely requires correct high-load or HL-rated tires, whether or not they carry an EV marking or not. That’s the place Jeff’s expertise turns into genuinely helpful. He’s not suggesting folks ignore load scores or run underspec passenger automobile tires to avoid wasting a couple of {dollars}. His conclusion is narrower. Should you match the load ranking appropriately, a well-engineered non-EV high-load tire can, in his expertise, meet or beat the consolation and sturdiness of the Kumho EV tires that got here on his Kia, with no noticeable penalty in vary or noise.

So what ought to an EV9 proprietor do when the manufacturing unit rubber wears away? The Fb thread suggests a rational guidelines. First, respect the fundamentals. Load ranking, velocity ranking, and dimension should match the automobile’s necessities. Second, be sincere about how and the place you drive. Jeff’s hilly, stop-and-go Western Pennsylvania routes will at all times be more durable on tires than Brian’s presumably flatter, extra constant miles. Third, weigh the tradeoffs. EV-specific tires could provide slight beneficial properties in effectivity and typically quieter building. Excessive-quality non-EV high-load all-seasons could last more and value much less, on the doable expense of a really small hit to vary which may be troublesome to understand in day-to-day driving.

The EV tire label represents a set of design priorities that may be helpful, particularly for engineers making an attempt to eke out each mile in official vary testing. What Jeff Bader and the opposite house owners spotlight is that, as soon as the automobile leaves the showroom and rolls into the numerous mess of actual life, these paper benefits don’t at all times present up as clearly on the driver’s seat or within the checkbook. EVs just like the Kia EV9 and Ford Mustang Mach-E are spectacular machines on any tires constructed to deal with their weight and torque. The sensible transfer is to deal with EV tires as one instrument within the field, not a sacred requirement, and to let tread put on, consolation, security, and value by yourself roads resolve whether or not that further seven hundred {dollars} is cash nicely spent or just a premium you possibly can skip.
