Am calling up junkyards looking for a surprise present for a friend with a 2019 Prius Prime. What specifications do i need to buy the right size used mounted tire? Many thanks for your help.
Third gen temp spare will also work; size is: T135/80D16 101M. It's actually closer in OD to 195/65R15 (third gen stock tire as well). 2nd gen temp spare will not work, since it's tailored to second gen stock tire size of 185/65R15. The part no's for third and fourth gen temp spare rims can be found on sites like McGeorge Toyota Parts, or Amayama. With a full-size (15") spare, one rim that'll work is an older Corolla steel rim: Corolla steel rim, part no: 42611-02471 (2003-2008 corolla or matrix, CE, LS, S)
