How much are you getting out of your tires? I have Bridgestone Turanza that came with my EQE sedan and it’s almost wearing out at 12K miles mostly highway driving! Is this usual for these heavy vehicles and are there any tire brands better than others?

I have EQE sedan as well, and it looks like my tires are probably going to be in the same ballpark for wear. I'll check tread depth, but I did notice that it seems to be wearing considerably faster than I'm used to. This seems to be very much the standard for BEVs. Most of my driving is highway, and I'm generally pretty easy on the accelerator, though on occasion I'll give it a go, or take a curve faster than usual. @shakoomakoo , do you have rear-wheel steering as well? I suppose it doesn't make any difference at highway speeds, but it's worth comparing notes. I have about 7800 miles on the car, and rotated the tires just below the 5k mile mark.

Some additional thoughts - I've been pretty happy with the stock Bridgestone LS100s, but they do have a bit more rumble than I had expected between 45 and 60 MPH. Grip has been fantastic. I'm considering the Bridgestone Turanza EV tires when it's time to replace the existing tires. I have the 19" wheels (255/45/R19), so the profile may significantly factor into your wear experience. If I can remember to get out the wear gauge, I'll try to get a reading on it this weekend and post here.

I have an EQE 350+ (RWD) sedan with the same Bridgestone tires. I also have 19" wheels. With 2800 miles thus far, wear doesn't seem excessive. I have read that BEVs in general will chew through tires, some recommend rotation (if a squared setup) every 5k miles.

when ever I change a tire it's for an obvious reason ! I change cars a lot

Thanks for the replies. I have an EQE 350 4Matic with air suspention. Tires are 255/45/R19 Turanza LS100. I am at 13K and I’m pretty sure I’ll need new tires by the winter. I think I’ll go with the hankook EV and see. These EVs definitely eat tires pretty quickly. Hi ave not rotated the tires since purchase.

Installed the Turanza EV 255/45/19 and have been pretty satisfied, very quite, handling is better than old ones and traction is excellent. I hope it last more than the non EV tires. The old ones also Turanza LS100 lasted 14K miles.

Wow, thanks for the update! I'm very interested in those tires. My car is at almost 8400 miles, and I have around 5/32" remaining. At this point, it'd be amazing if they saw more than 10k miles. I'm honestly a bit surprised, I'm generally pretty easy on the tires. The Turanza EV tires have a warranty on them, can one claim against it if they don't last the promised mileage?

Also, have you noticed better or worse consumption? I have an EQS loaner at the moment, which has Pirelli EV tires with foam insert, and though it's more aerodynamic with respect to Cd, the giant 21" wheels and extra weight make a huge impact on efficiency. Best trips are getting about 330Wh/mi vs 270Wh/mi with my EQE on 19s, which is also a few hundred lbs lighter. The EQS is a 450V4, my EQE is a 350V4 with acceleration increase.

The warranty is 50K miles. I don't recall I have ever got what tires claims on warranty but if these tires give me >30K miles Ill be satisfied.

shakoomakoo

Consumption is also better but not by much. They claim excellent tread life which is mainly why I bought them. Tire noise is non existent and wet traction is also very good. Time will tel how long they last.

What tire pressure are you guys using? They set the new tires to 41 psi front and 46 psi rear.

bytemaster0

Very good to hear on those counts. I'm virtually certain it'll be the next tire I put on. A little worried that it's slightly larger in diameter, but that'll wear down in no time anyway.

I set my tires to 42/43 F/R. I think stock is 41/42 or so. 46 too high for rear unless you have a lot of load.

For anyone that has extensive tire material properties knowledge - I read that the Turanza EV tire has silica to improve rolling resistance. As the tire wears, surely the silica is ejected in some shape or form, to some degree, as it drives. Silica is quite abrasive in granular form. Would such a tire cause damage to paint as it wears? It sounds stupid to ask as I type, because surely it's not in some granular format, but I have to ask!

Background on this is that our Bridgestone Blizzaks actually do release silica to improve ice traction. Hasn't caused any noticeable paint damage on our GLE, but it's still a possibility I suppose.

Looks like my Turanza LS100s will last me about 9k miles. I just plugged a nail at 8400 (MB didn't want to patch it as it's about an inch from the sidewall), and there's about 3mm left, give or take some. Costco is having a special on the Turanza EV tires, and they have a 50k mile warranty, so I'll probably be ordering soon. Amazing how little tread life I got out of the OE tires.

I have just a tad over 10K miles and the car is 10 months old and I'm at the wear indicators with the Bstone Potenza's on 20" wheels. I run 41 PSI since I'm the only person in the vehicle. On our EQS SUV with the good years and teh staggered setup we are past the indicators and the car only have 7.5K mile and is also 11 months old...

Tires go quick on these cars... My C63 gets a tire change every 20K miles or so and its riding on Michelins pilots

I think that's the problem with "EV Compatible" tires that simply meet the sidewall load rating. To be fair, the Bridgestone Turanza LS100s have had great grip and excellent handling, but the tread life just isn't there, at all. Turanza EV tires are going on next week, once I can eke a few more miles out of the MO tires. I'd rather not deal with cold wet and even snowy conditions with the tires so close to the wear bar. I know one other form member went to the Turanza EV tires. I think it's important that we report back here from time to time to evaluate treadwear and driving experience on EV-optimized tires, and whether or not we're able to get the mileage warranty credits on new sets as needed.

First few hundred miles with the Turanza EV tires and I'm pretty happy with them so far. Efficiency is perhaps a smidge better, probably within 5% or so margin of error, though I'll have to measure again in warmer conditions to have a 1:1 reference with the OE tires. Ride quality is excellent, road noise is great. There is a slight band of tread noise at around 40 MPH, but it's not as bad as with the LS100s. Highway noise is great. Saw a Tire Rack story on the Continental ProContact RX EV tires, maybe those would've been slightly better. I'm surprised at the large efficiency difference between it and the Turanza EV in the Tire Rack test. Maybe I'll have to give those a go next time, although they haven't released their conclusions on treadwear and winter snow/ice performance. It's such a hard balance to achieve, especially on an EV platform.

Updated: I think efficiency of the Turanza EV tires may actually be worse. It's very hard to tell though, but even when I use Eco+ mode for HVAC, which only uses waste heat, the Wh/mi is significantly higher. It is also a lot colder, which means higher air density and thus resistance, and the tires are brand new. Car may also be minimally heating the battery to keep the ion chemistry happy. Does anyone know if Costco has a satisfaction guarantee on the tires? I've written Bridgestone to see what the coefficient of rolling resistance is for the OE LS100s and for the Turanza EV tires, as it's not published anywhere.

Okay, so this might feel like whiplash, but I'm returning the Turanzas and going for Continental ProContact RX tires. I didn't want tires with a foam liner, but the range loss with the Turanza EV tires is too substantial. I put the car's HVAC in ECO+, which should disable most if not all cabin PTC heating. I did notice a tiny bit of power draw during the first few minutes, I'm guessing it was applying a bit of heat to the batteries to keep them optimally conditioned. But once that stopped, I did my usual test loop and I was recording 350 Wh/mi, when I used to get 280 Wh/mi with the old Turanza LS100s. TireRack confirmed the range issue with the Turanza EVs, with a 50 mile range difference between it and the ProContact tires in a range test. I know that the cold has some bearing on it, but it wasn't nearly this low when I had the LS100s on, so it seems that Bridgestone sacrificed range for noise reduction without foam. I'm not looking forward to the repair process when the ProContact tires inevitably get a nail in them, but it beats a 15% range reduction in the vehicle perfromance.

Switched to Continental ProContact RX T1s, and I'm glad I did. The Turanza EVs are *slightly* more comfortable in their ride, but the EQE's suspension handles the difference just fine, it's more subjective than objective a difference. However, the range differences are significantly noticeable. In slightly colder weather, the ProContact RX T1s squeezed out an extra 45 Wh/mi, which is an impressive difference. Account for the fact that the lights were on, and there was a bit more cabin preconditioning that I did when testing the Turanza EVs, and the difference is even bigger. Overall, the results square off nicely with TireRack's own testing. With such an efficiency difference, that means that the ProContact RX T1s will yield essentially 40 more miles - that's a huge difference. I've seen plenty of posts that anecdotally list the Turanza EV as performing worse than the ProContact RX T1, but it's nice to be able to match it to actual performance that I can measure. I'll be excited to see how they do in the summer - assuming they last that long!

Wanted to add a quick update now that I have driven >10K on the new tires (Turanza EV). Definitely better better tires then the stock LS100, I still have good tread, traction is good in rain, range is also good and its extremely quiet. Range was initially low when I first installed them but I think that's because they were brand new and that would be the case with any tires. I would buy these tires again.
