Do tires on electric cars wear faster than tires on regular cars?

Yes, they do wear faster than tires on regular cars. To begin with these are
high performance tires - with an aspect ratio of 35% to 45% and a speed rating
of W or Y are not known for long wears. Car & Driver projected tires to last
no more than 30,000 miles per set.

Some of the Tesla tires were designed with many features from width to rubber
composition to the tread block shape, which help reduce road noise. ContiSilent
takes all of these existing features – including those of even the most sound
-optimized summer tire – and adds an extra layer of sound proofing to deliver
a quieter driving experience. And the difference? It’s significant: a 9 dB(A)
reduction in the components of rolling noise perceived as particularly annoying
inside the vehicle.

However according to Tesla forum, most driver couldn’t hear or feel the difference.

Secondly, electric cars develop the most torque at low rpm, that high instant
torque to propell the vehicle with neck snapping acceleration means also more
wear. What’s more the regenerative braking will impart braking forces once
the foot lift off the accelerator so the increased braking torque both in
duration and frequency will take a toll in the wear of the tire.

Lastly, the weight of these vehicles being heavier by 500 to 800 lbs compared
to the ICE powered cars will cause more tire wear. The heavy batteries located
under the vehicle’s floor provided better handling due to the lower center of
gravity which many drivers may take advantage of it and drive accordingly.

Many of the newer tires for EVs have a greater load carrying capacity which
means higher inflation to handle the extra weight and improve corning capability.

According to Car & Drivers test most of these improvements on any vehicle will
not improve MPG numbers more than 2%. My recomendation to get better longevity
out of your EV tires is to drive smoothly. Reduce sudden acceleration or high
speed cornering and adjust your re-gen braking down a notch. It is possible to
use a lower speed rated tire with harder compound to improve longevity.

Many shops are selling those tires with H or V rating and owners have reported
long wear with them. If longer tire life is your goal and that extra performance
don’t mean much to you as you rarely drive above 70 mph, it may be worth while
to look into it.
