Sailun Erange Ecosphere Tires for M3

[lynnpt2001]

Moderator note: This thread was originally posted to the Model S forum.

I just installed Erange EV Tires | Tires designed for your Electric vehicle on my 2019 M3, 89000 miles this is the 3rd set of tire. Have been running the Michelin Primacy tires until now. Always thought the Michelins we relatively quiet, especially when new. I took a chance and bought these tires at $ 145.00 each and they have only been on the car for 3 days, so it is a little early to draw too many conclusions but these are quieter than the Primacy tires hands down. Also I can already tell they do offer better range, not sure yet how much but my drives to work have shown lower WHPM when the weather has been consistent. Hope they stay this quiet and are trouble free, time will tell.

This is the S forum. I don't think the tires are the same with the X.

Erange makes tires for all Tesla models. Looks interesting. I may consider them when replacing my tires.

I tried to locate these Erange Ecosphere tires here north of Seattle. No luck at Discount Tire or Midas. I’m getting Primacy’s again, I guess. Midas actually told me this AM they “don’t service Teslas”, though Midas was listed as an outlet for Sailun Erange tires. I don’t know if this is franchise-wide. If I can get the tires, Discount Tire will install, for a price.

Two of my 1500 miles OE AS4 275/35/21 got hit by the nail on the thread that's too close to sidewall, force me has to replace them. Wanna try out something new so I went with the Sailun Erange 275/35/21 all around.

I think this is by far the most fair comaprision you could find, as many out there compare their "worn" tire to "brane new" tire.

This comaprsion is bascially new to new.

Sailun tire run wider in thread, as you can see the below. I cacualte my wheel spec to be a perfect fit for my Y, and no rubbing. Soon after I switch to the Sailun, it rubs when I hit bigger bumps. (time to add more camber)

21x10 ET25 sqaure

Left = Michelin AS4 275/35/21 T0
Right= Sailun erange 275/35/21

The thread doesn't look promising in the snow condition imo. They look very alike to summer pattern. But I guess there's only one way to find out.

1. Efficiency:

I've driven around 300 miles on these tires so far, and the efficiency performance is worse than the AS4. 310 wh/mi (AS4) vs 335 wh/mi (Erange).

1. Noise:

The AS4 is hands down a much quieter tire. Sailun has this whining noise at 55mph and above. Maybe it just needs to break in a bit, but as of right now, I'm not enjoying it.

1. Comfort:

In terms of small bump absorption, the AS4 takes another point. Sailun isn't as comfortable as the AS4 in pretty much all aspects.

1. Handling:

The tires handle just fine, but still not as precise as the AS4.

Conclusion:

If I give Michelin AS4 a 9 out of 10, sadly it will be 4 out of 10 for the Sailun. If the whining noise would go away after some driving, I would bring the rating to 6 out of 10.

I have 10,000 on my Sailun tires on the M3. All is good so far. Only complaint I have is around 74mph there is a light droning sound from them, like a harmonic frequency from the tread design perhaps? Not sure and foam may have suppressed it if it had been installed. They are not great in the snow but better than the Michelins that came on the car. They do get slightly better range but not enough to rave about. Except for the 74mph noise they are a good tire for the $. If you want to save money they are a good option. Or you can get a better tire for a higher price
