I don't think there's a major problem with the cheaper rim/tyre combo's, value for money is a great thing. Personally only a hand full of wheels actually look any good and going stupidly large is a step backwards in driveability tied in with the fact that 20" wheels don't look any good on a rex. All the big plastic chrome wheels on the market look tacky and cheap, if you want a nice big wheel that looks the part you'd start looking at a true 2 or 3 piece wheel. Notice how 1 piece forged wheels for jap cars come up to 19", anything over is a composite wheel. Those one piece 20's are cheap for a reason. In the end its your car do as you please.
