Wider tires would definitely put more stress on the wheel bearings.
565.6 mm in wheel diameter.
1777.1 mm in circumference.
646.8 mm in diameter.
2032.2 mm in circumference.
2032.2 - 1777.1 = 255.1 mm difference per revolution of the tires.
255.1 = 14.3 % of 1777.1mm
The actual speeed of vehicle when using the R17 tire would be 14 % faster than that shown on speedometer.
Even if you use 30 series low profile, the R17 rims would still have too much difference.
Long time since I last did such calculations so hope I am not wrong with these.
