About a week ago I had new tires put on, same Goodyears as OEM. Since that time I've noticed significantly lower efficiency despite comparable temperatures (it's been a bit colder, but even on warmer days my efficiency was down). Pre-new tires I was getting around 280-290Wh/mi on my usual commutes. Since then I'm closer to the 320-330Wh/mi range. Now, I might just attribute that to the new tires alone, and perhaps it still is just that, but since the new tires there's a bit of a shimmy/wobble sensation I can just barely notice. It reminds me of the crabbing of an all-wheel drive car at low speed. It's only noticeable at low speeds (up to maybe 35mph) and it's very subtle, no visible steering wheel movement or anything like that. My question...is this more likely a wheel out of balance--seems sort of likely since the only change is new tires? Or is it an alignment issue--seems more likely with the wobble/crabbing and lower efficiency? Or is it just new tires breaking in and I need to shut up and be patient? Or something else. I could take it for an alignment, but there's no local SC, so I have to use a local shop and go through the process of teaching them how to deal with the car and pay out of pocket. I have another 4000 miles (~2 months) before my next service appt. with Tesla and don't really like the idea of sending the car away for just an alignment that it might not need. Looking for logical advice on how best and most economically to proceed.
