HI,
simple question,
How many kilometers do you do on your tyres?
Yesterday I turned the tires (10,000 km) and the front ones are quite worn out, the tire specialist told me it's normal on electric cars,
the cars have more acceleration and wear the tires a lot,
he told me even now specific tires for electric cars are starting to come out precisely to improve tire wear on electric or hybrid cars.
However I use the car 90% in the city and I have 4 season tyres,
maybe I can get to 20,000 km.
Greetings
(Sorry for the mistakes I used Google Translate)

I have the same car, running on 185/55-16 87H Yokohama Bluearth tyres.
Current mileage is 19500 Miles (31380Km) and there is 4.5mm remaining on the front tyres.
Granted the max torque is higher than conventional cars, but I believe it is delivered more smoothly.
-
My question: what size and brand of all-season tires do you have? I now have 14,000 km. driven on Vredestein Quatracs (185/55 R16) and the front tires still have about 6 mm of profile.

HI,
these are the tires I'm putting on,
Bridgestone Weather Control A005 Evo,
the front tires are very worn on the sides,
it must be said that the city where I live has many roundabouts,
I took those tires because they have an A-rated wet grip.

I have only done 20,000 km /12500 mile so far,probably half of it on motorways, and I have two sets of wheels, one on original summer blue earths, and a set on Goodyear vector all seasons. I intended to record exact mileage done on each set but I lost count. But its about 10,000 km, 6000 miles on each set. The blue earths have some wear on the fronts, but evenly spread and not excessive,They should last at least 20,000 miles /30,000 km if left on the front or longer if I swop fronts to rears.
Less wear on the all seasons, and they will probably last even longer. It may surprise some that despite their more open tread pattern All season tyres often perform well for tread wear mileage.
Some excess wear is probably due to the extra torque. But you dont always have to use it all ;D
I can understand Wonder's point about roundabouts. I do tend to use the extra torque ,with no need to change gear on the roundabout ,to merge with other traffic in a more ' positive and assertive' way,(ie sometimes a bit faster ,taking opportunities I may not have taken in a less responsive manual car. :-[ ) This may increase tyre wear slightly not just for accelerating, but when cornering.
Edit - added after Kremmens next comment. On a previous car my daily commute involved a tight U turn. Over time this resulted in increased tread wear on the outer edge of the nearside front tyre.
-
If you are 'enthusiastic' on roundabouts and tighter bends, tyres can wear a lot quicker on the outer edges.

Perhaps a slightly higher (0.3 bar) pressure would help... also saves a (little) bit of fuel.

My factory tyre, Yokohama blue Earth 185/55R16 lasted 39000km after one late rotation and a wheel alignment.
Let's see with the new 4 season ones what I can achieve.
I'll rotate them more regularly than the previous ones.
-
My Falken Euro All Season tyres on my Crosstar are about half worn after approx 15,000 miles. I thought they'd worn excessively until I worked out the approx mileage. Im happy with that, but I tend to change tyres as they get to 3mm, and certainly before winter. Cheers! 8).

HI,
I will probably do so, also because I certainly rode with the tires a little flat,
no warning light came on (strange) but the tire specialist told me that my tires were a bit low in pressure,
so keeping the correct pressure even a little higher I hope to consume less tires.
With the tire warm, how much can the pressure increase with respect to the set one?
-
0.2-0.3 in summer

That is for the producer to worry about, as long as you stick to the recommended pressure. ;D
When the pressure is too low, the tire warms up more, due to deforming more. But never, I mean NEVER change pressure when the tires are warm. Wait till they are cold!
And check on your B-pillar: although we never drive 160+ km/h, I do stick to the recommended tire pressure for that speed. So front wheels 2.7 bar (39 PSI), rear 2.6 bar (37 PSI).
-
I use the lower 35 / 33 setting for the softer ride.
-
That I recommend a bit higher pressure is to prevent / reduce this:
the front tires are very worn on the sides,
-
Some cars use expensive tyre pressure monitors in each wheel to send radio signals to the car . Their monitor batteries can go flat. The Honda system does not measure pressure. It monitors the speed each wheel rotates compared to the other three wheels . If one tyre loses pressure its overall size gets slightly smaller, with more wheel revolutions per km. This will be detected. But if all 4 tyres are set at a lower pressure than recommended (maybe because the tyre pressure gauge used is giving an inaccurate higher reading ) it will not be detected because all 4 wheels will still be rotating at the same speed relative to the others. -
The system 'learns' that rear tyres my rotate at a different speed to front tyres due to the different pressure setting, or that a worn tyre may rotate faster than a new tyre due to having less tread. depth. It calibrates the expected rotation of each tyre and then detects any unexplained variation due to pressure loss. It also allows for the fact that tyre pressure goes up as they get warm . The pressure rise due to heat varies , depending on air temperature, distance travelled etc. But all four tyres increase by about the same amount so their rotation speed relative to each other does not change.
You dont need to know by how much pressure rises when warm, just be aware of the fact it does rise As Jazzik says always measure tyre pressures when tyres are cold. The recommended pressure is set for cold tyres, and allows for an expected increase in pressure as they get warm. If you took pressures on warm tyre and reduced the pressure to that recommended for a cold tyre it would be too low once the tyre cools down. Bear in mind that 'cold' in summer, and 'cold in winter are not the same temperature, so its important to check tyre pressures regularly. Tyres last checked 'cold ' in summer may be too low a pressure for winter air temperatures.

I got to 15,000 miles/24,000km on the original Yokohama front tyres before they were down to below 3mm and 20,000 miles/32,000 on the rears.

When rotating tyres, it it necessary to get them all re-balanced again?
-
Not necessary but my tyre center does it, and sometimes they need some little adjustments.
