TL;DR: Tesla has substantially higher tire maintenance costs compared to other cars in its class, or even compared to the RAV4 Hybrid.
Tire-related maintenance and replacement costs for Tesla vehicles are so much more than with a conventional vehicle the same size, it negates much of the cost savings the Tesla’s low-maintenance powertrain design offers.
This ends up as a wash, all those (cheap) oil-changes may add up to some costs by 100,000 miles, but the amount of wear-and-tear on a Tesla’s tires more than makes up for the cost and then some.
Tesla’s Model Y has a 100,000-mile maintenance cost estimate between $8,250 for base trims and $15,000 for the performance trim. This does not include repairs. By comparison, a Toyota Highlander in the Car Talk fleet had a 100,000-mile maintenance and repair cost of $14,029. A Honda Accord had a 100,000-mile maintenance and repair cost of $7,684. If there is a cost advantage to Tesla with regard to maintenance and repair, we cannot find it.
My home has my breaker box inside of the garage. So my home charger should be very cheap to install. Under $1k is what I expect.
But a good friend of mine has a breaker box on the other side of the house compared to his garage. It’d be a lot of fishing wires through the drywall to install a new 220V line… I think some people were talking $3k or so for installation costs.
One cool thing about PHEVs is that 110V is more than enough to get ~50 mi of charge per night (4mi / hour charge * 12 == 48mi or so of charge). L2 chargers are still nice so that you can get a faster charge if you make multiple trips in a day (ex: go to the grocery store, come back, charge a bit, go to Church or something, I dunno…). So I think L2 still is worthwhile. But its not needed on PHEV. After all, if you ever run out of electricity, just fill up at a gas station.
