Last night Ian Callum had a big smile on his face discussing the 22in wheels he’d designed for the Jaguar F-Pace, the largest alloys seen on a Jaguar and the largest offered in the segment.

Which got me thinking: how big can alloys go? And to what cost to ride quality?

Callum said a bigger SUV (not that he was committing to doing one…) would mean bigger wheels again, but 22ins was the right size for the F-Pace; 23ins wouldn’t look right to his eyes.

F-Pace engineers Andy Whyman and Dave Shaw said that the bigger wheels had not meant a lower profile tyre, and that the F-Pace’s 22in wheel offered “superior grip, comfort and greater sidewall protection than rival 20in wheels”.

All the wheel sizes on the F-Pace (18in, 19in, 20in and 22in) had tyres of the same diameter and rolling radius, which meant ride quality can be tuned closely between the different options. The 22in tyre is a summer one only however, so don’t expect the same level of off-road ability on that one compared to the smaller wheels.
