I drove a 2001 Prius 135K
I drove a 2001 Prius 135K miles and the brakes were above 60%. Battery died and killed the transmission, cooler pump and more. Original tires lasted only 20K. Different tires lasted 65K.
My 2013 Volt (now 47K miles) had to replace tires at 33K miles as tire wear was bad on the outsides. Always kept inflation to 42psi, even the new tires. Old tires got great electric miles, up to 47 Emiles per charge. Changed tires to more aggressive LRR and am getting 38 Emiles now. Tires are warrantied to 60K and appear to be wearing flat. Lower mileage is OK as tires are expensive to replace and cost more than Emiles saved. Only car problem is both drive shafts have been replaced. Glad I bought the 100K all inclusive warranty. Brakes estimated to be on a +200K mile wear schedule while using the regen braking as I do. I drive in L mostly and use it to slow down (regen) often. Probably irritate those behind me. Note the new tires are Bridgestone Serenity plus. 65K warranty, great traction, stopping and cornering but Emiles are reduced. Still get 38 on long trips though.
