37 pic 1 appears to be a solid lock ring wheel. It will have indents on lock ring along inner edge. You may not be able to see them until you deflate tire. Once you locate the indent with tire deflated you use a tire iron inserted into indent to pry lock ring out of wheel slot. On 37pic 2 I couldn't get a clear image to tell if it has a lock ring you should be able to compare it to the front wheel.
