The original specs are 19" with 45 profile, but I was not very fond of those original rims and also needed a second pair for Winter, to change with ease. Always kept to Jaguar original and also looking at past models, then I found Volans. Those where the original rims for the 2007 Jaguar XF SV8 which made it a perfect match, balancing a simple yet powerful design with a bit of history.
