Tire Selection for 987.2 Base Boxster - 2009 MY 17" Rims

[sudheendrar]

Facing a problem getting the following size tire set in Michelin PS/2.

Front 205/55R17 Rim Offset 55mm Rim Size 7 In
Rear 235/50ZR17 Rim Offset 40mm Rim Size 8.5 In

Local tire stores can order for Continental - same one I have on my OE.

Wider tires have more options if I go this route:

Front 225/50R17
Rear 245/50R17

What are the risks of going this route? I am not sure if the options are N1 or N2 rated.

Any advise is highly appreciated. Need to get tires replaced before inspections.
