The $45 Achilles that I received were a pretty recent build date. They're pretty quiet with the curvy "aquatread' style deep tread blocks, and I have high hopes for their wet performance... like that'll matter in Vegas. My range has gone down, but I'm comparing to an old set of Enasaves that were just about bald, and ran the first couple weeks of the new tires at 32psi. Plus I was very unscientific about it, replacing the front tires at the same time with new Continentals....
There's a "more money than sense" family on you Tube that posts waay to many Tesla non-adventures, but they recently ruined a good Model X tire to demonstrate the foam pad that's glued to the inside of Tesla tires. Anybody researched adding that feature? Ensasves sound like a snare drum on our rough roads... Here's an epic thread where some TESLA owners added the foam. Final conclusion after multiple attempts (with instructions in post #236) was that after some short term successes, the foam eventually debonded and created a bad tire imbalance...https://teslamotorsclub.com/tmc/threads ... 598/page-8
I think they missed the boat, and just need a donut cut out of the foam that includes a dense vinyl layer, with an inner diameter slightly less than the rim's and an outer diameter of 15 " or slightly less, to simplify tire installation. Stretch that puppy over the rim so that is clings to the inner rim diameter like a rubber band. That'll absorb both the sound waves resonating inside the tire (like a pillow in a bass drum), and also the vibrations being transmitted by the wheel through the hub and bearings. There's a foam fabricator nearby that I'll try, but unfortunately am now probably almost two years away from needing any more i-MiEV tires..
