it may well be my error but when I checked Pep Boys' website, they do not show having any 135 (70-75)R15's in stock .... neither does Tire Rack .... if Elio goes with tires this size, it appears replacements may not be too easy to find .... if Elio proves to be the only vehicle using them, the price will certainly go up

Not an error at all. Like I said these sizes are for donut spares and 135R15 (135/80-R15) are used in for classic cars so they are specialty items.
The way I see it we have to hope that thanks to the large production numbers of 60K+ in the first year alone that replacement will be made available by several industry players therefore making the tires relatively affordable. The even better option is to simply use an approximate equivalent tire which is more widely available. For 135/7X-R15 tires the widely available equivalent, which is virtually identical in size, is 145/65-R15 which Continental also makes and you can buy at Tirerack right now for about $75 and it is in stock at my local Pep Boys for $80.
