I'm looking to put some after market wheels on my 2021 F Pace 250S and it has the 20 inch Rims from Factory.
I was told that if i go Aftermarket i would need to buy some Hub-centric rings to make sure they fit properly
My question is, What size would i need ? Has anyone gone down this road before that might point me in the right direction ?

 

You only need sub centric rings if the hub bore on the wheel you are buying doesn't match the hub bore on the f pace. I did that on my XF with aftermarket wheels and got some aluminum rings of the right size. Any wheel shop can make sure you get the right ones

Correct one for the car is likely 63.4mm like pretty much all modern jags
And the bolt pattern has to be 5x108

You will also want to get the right offset to ensure you don't have them too far into the wheel well or poking too far out. Depending on whether you get wider rims you will need to calculate the right offset. Lots of online calculators for that

If you know the wheel you are looking at, size, width etc and post it on here I'm sure someone will help on the other specs

 

This is the specs from the Wheel im looking at

• Offset:+45mm
• Backspacing:6.496"
• Bolt Pattern:5-108mm

 

Is is a 20 inch wheel again?

And 8.5inch wheel width like the OEM ones?

If so, a 45mm offset is fine. That's same as OEM
And bolt pattern is fine too

For hub rings you need to ask them what the hub bore is on the wheels and you will need a ring if it's not 63.4mm
