In US we are pretty much stuck with Bridgestone.

There are a couple of design choices that further shorten tire life, though-Arm said:This is a specialty car. It has specialty tires. It's just a fact that i3 owners need to accept and deal with. This topic has been discussed ad-nauseam and clearly the answer always comes back to one or two types of tires.
The car eats tires it seems. Which isn't ideal but it is what it is. I personally wouldn't put cheaper tires on this car even if they were available.
For owners who need to change their tires every year....that's alarming and really not reasonable even with this car. Something else is amiss in a case like that.
If I decide that our 2019 BEV needs a wheel alignment, I would ask that the rear camber be set to the minimum of -1º 35' (the spec is -1º 40' ± 5'). I doubt that 5' would make much difference in inner rear tire wear, but it might be worth trying.Egbert said:2. Aggressive rear camber settings at -1.7° force more wear on that shorter inside tire groove.

1. The inner groove on the Bridgestones (EP600) is only 6/32" out of the box, whereas the outer two grooves are at a more typical 10/32". If you live in a state with yearly inspections, they won't let the tire go if any groove is 2/32 or less. So with only 4/32" of wear available to you, tire life is much shorter.
2. Aggressive rear camber settings at -1.7° force more wear on that shorter inside tire groove. I assume this setting is a deliberate choice by BMW to give the car more of that typical BMW handling, and perhaps to help keep the rear from stepping out under regen in less-than-ideal traction situations.
I agree with you that it is what it is- we are but consumers of this product after all. But, it also seems wasteful that after about 16500 miles, I'm going to have to toss these tires in February because of the inside groove depth, while the rest of the tire has 6/32" left in it. I wonder what motivated Bridgestone to make that design choice, but it doesn't seem very environmentally friendly to throw away a tire that has 50% life left in the majority of the tread.
Their E.U. rolling resistance rating is a pretty poor D. This isn't as problematic on a 120 Ah i3, but it would probably be on a 60 Ah i3 with its limited range. I can detect the decrease in rolling resistance when I increase the inflation pressure of the standard Bridgestone tires by 10 psi over recommended, so I suspect that these Momo tires would feel like driving in deep mud to me.fkacct said:Fair warning, these tires weigh 23lbs each. That is 2 lbs more than the Ecopia EP500 195/50/20 tires and 5 lbs more than the 175/55/20s. Will it actually make a noticeable difference in range? Not sure.

The purchase cost savings might be more than the increased electricity cost as a result of decreased range, so these might make economic sense. However, at only $75 per tire, I would be suspicious about its quality.
