I've since updated my blog as to include what happen in more detail when we tried to purchase a set of wheels from a verity of retailers.

Wheelpros has since removed the 775's from the Transit Connect calculation system. But the wheels are still on their site. The other thing I'm still seeing at many of these sites and anyone interested in buy wheels, need to verify in person if these wheels fit. Reasoning, any one of these sites is going to tell you "looks good on paper" but as we found out.. it just doesn't fit or it was totally unsafe.
lastly, here a few sites I've used and continue to use in order to locate wheels for other transit Connect owners. Mind you my searched are limited to the 2014_ Current, so with a few adjustments, you can find your specs for your older Transit Connects.

But once you enter the 18, 19 & 20 range it going to be extremely hard to get a matching load rating.. But things change and the longer we wait, the more options become available to us. Assuming we send request to manufactures and make them aware we need these types of options.
