Have you ever wondered what difference ticking the big wheel size option makes when specifying your new car? In this video I find out! I use a new Porsche 992 911 which comes standard with 19" front and 20" rear wheels, and test them against the optional 20" front and 21" rear wheels!

Both these wheel options use the new Michelin Pilot Sport 4S NA0 tire which is specifically designed for the 992 911. The standard tire sizes are 235/40 R19 front and 295/35 R20 rear and the optional big wheel size is 245/35 R20 front and 305/30 R21 rear.

As usual I test the braking performance in the dry and wet, dry lap time, wet lap time and look at the noise and comfort of the two different sets of wheels.

Does fitting big wheels to your car really ruin the handling? Do big wheels make you faster around a track? Only one way to find out! Lets get testing.
