Whoa! I need to retract what I said in my previous post. I purchased a set of chains from quality chain that I posted previously but it turns out that they cannot be installed due to interference at the wheel. They do fit 175/60R19 tires, as we discovered after having difficulty installing one while the wheel was still mounted. However, it is impossible to remount the wheel due to interference. (I assumed the concern about chains having to be low-profile S-type was due to tight circumference of the wheel well and there is no issue there. In this case there is interference where the wheel is mounted, top inside.)
Bottom line - the Quality Chain Corp chains are very nice quality chains that fit the i3's tire size, but they CANNOT be installed on an i3. My sincere apologies for the misleading post! I am going to try to return mine. :-(
(If I knew how to edit or delete what I posted earlier, I'd do that, but I don't!)
Sorry!
