The limitation on tires for the Transit Connect stems form the fact that the rear tires take 49 psi in order to carry heavy loads. If you never carry heavy loads you could maybe reduce this pressure but that would cause problems with the wonderful tire pressure monitoring system. There fore you should select an "extra-load" rated tire designed for pressures of at least 49 psi. There are only a couple of such tires on the market. I like the Nokian Entyre.
