Can replace the low profile tires and rediculously soft alloy rims on the Sport version with rims and tires from the other models?

yes u can , but be careful and see that the wheels match the engines power, the bigger the engine the bigger the wheels r to control that power hope this was helpful

Pot holes !!! well i live in Quebec and we know pot holes for sure lol got 22000 km and so far real happy. i always used to change original rims and used to get much more problem with aftermarket ones
