Hello there,

I'm planning on swapping wheels in order to gain ground clearance since my lawn is quite uneven.
Current ones are 13x5-6 rear, 11x4-4 front.
According to the manufacturer, I could theoretically put the 13x5-6 to the front, and install 15x5.5x6 on the back.

However, when I look at the lawnmower, the back rim doesn't look like the front rim, aside from size.

Here's the back rim

And here's the front rim

The metal part securing the axle is longer on the rear compared to the front.
Three questions :

1. Can I still convert the rear wheels as front ones ? Don't mind some elbow grease
2. The manufacturer suggests 15x5.5x6 as maximum for rear but 5.5 seems rare and pricy in my region. Will 15x6x6 fit no issue?
3. Will the new rear rim need to have this extra metal part holding the axle?

Thanks a lot for your help and expertise
