10% difference. seems like a lot. underinflated?
Yes, had them installed last Thursday. Can’t tell any difference in noise fro the OEM Goodyears that came on the car. Ride and handling seems fine. What has “shocked”me is the huge difference, so far, in the wh/mi.That has gone from 303 for the first 40,000 miles, to 339 after the first 1000 miles on the Quiet Tracks. Normally, I can make the trip from my house to Nashville on a single charge. Definitely was unable to do that over the weekend. Gonna continue to monitor it for a few more days. If that continues to hold, I’m planning to go back to Costco to discuss switching to Michelin’s. No idea if they do that.
Thanks for the feedback, the Michelin sale ends tomorrow ($140+ savings) and I need new tires in the next few months and don't want to risk waiting around for another sale. I think I am going to stick with the MXM4 that i currently have on the car for my next set.
Curious if you have any efficiency with the QuietTracks? My local Costco just got them in stock and was considering purchasing but efficiency is a factor for me. TIA for info
I have seen LRR to standard tires hit mileage on an ICE 10%. Some of it can be a sort of break-in period, tread wearing in, and an old vs. new tires thing.
Worn tires have less tread block to squirm and wiggle wasting energy.
How many miles did you get out of the MXM4's? Anything you didn't like about them?
So, the wh/mile could go down as the tires age??
A vote for Bridgestone here!
Most Tesla's in Australia come with the Michelin Primacy 3 so I was nervous to switch away from them after 2 sets since new. Bridgestones are cheaper (3 for 4 deals) but I feared they would be louder and harsher. The opposite! They seem quieter (Primacy's are already very highly rated as quiet on Teslas) but even if I'm wrong, they are at least as quiet. The ride feels the same.
The handling is significantly better. The Michelins were solid, but in comparison they feel dead. The S007As feel lively and quick to respond to minor inputs. It's like the Michelins had a large null (dead) zone at centre. The road feedback is much better - driving on Melbourne's tram tracks actually feels different with the Bridgestones.
Corner turn-in is sharper. Slides don't last as long (the Bridgestones bite sooner). On launch, the Bridgestones slip about 25% less and launch sooner. In the wet with some lock on the Bridgestones hold a little longer before letting go. They also grab traction again sooner than the Primacy's did in the same corners.
Overall, the Bridgestone S007As hold traction a bit longer and when they do lose grip they find it again sooner than the Michelin Primacy 3's, and with no loss of ride quality or noise increase. I assume they will wear faster but I'll just keep buying them '4th tyre free'. Wh/km (range) is still the same but it's only been a couple of weeks. Don't really care - why is everyone obsessed with range anyway? Arrive home with 15% instead of 21% battery - who cares.
I haven't tried the Michelin equivalent (Pilot Sports) and assume they too would handle much better than the Primacy 3/Primacy 4.
I replaced the OEM Goodyears on my 2018 MS 100D in April. I’ve only purchased Michelin tires for many years, but I decided to try the Bridgestone QuietTracks because of the great reviews I had seen. Over 42,000 miles I had averaged 303 wh/mi with the Goodyears. After 2,000 miles I was averaging 339 wh/mile with the Bridgestones! I noticed the increase immediately and tried varying my driving to get that number down, but no success. I went back to Costco to express my disappointment and they offered to give me full credit for the Bridgestones and choose a replacement. I chose Michelin Energy tires. After 1,000 miles I’m averaging 262 wh/mi so far. That’s a huge difference! I’m not making a comparison as to other qualities of the tires, but I’m very happy so far.
Cool. I do suspect my wh/km will be worse with the Bridgestones, but keep in mind I've got the performance S007As, not the quiettracks (Turanzas) which are more touring.
I just think a small reduction in efficiency (many of us old school owners don't ever pay for electricity) is worth making the MS feel more nimble like a M3.

Are Michelin Energy tires rated for electric vehicles?

That’s not the tire I got. That tire is not available in 19”
I. I have a one year old set of the same 245/45/19 Michelin Pilot Sport A/S + on my old stock wheels, but I decide to keep these for backup for my wife's Model S, once she wears the Michelin Primacy MXM4's off her current wheels.
