Hi all,

I would like to ask your help, because I'm in a big hesitation now. At the moment I have 20" wheels but I hate them, because the road conditions in Ireland got worsen over the years and I van feel all the smallest humps on the road or potholes. Unfortunately some of them are unevitable so my wheels need to be welded in every 3 month if I'm lucky ... Previously on my 5 series I had 18" wheels and I never had issue with them for years.
I would like to downsize to 18" but as my car is an XF-S the 275BHP I'm a bit skeptik if it's doable. Recently I tried an 18" from an F Space but I couldn't manage to put them on as the brake caliper was hitting the inside wall so with 30 or 40 mm spacers I could be able to do it. Possible to put 18" on XFS ? Of they came off from another XF ?
please help me with this matter, what size I can fit on my car ?
I know the ride feeling will be different but I would feel better anyways.

I found a set original Jag 18"s with these specs :

PCD - 5*108
Size - 8*18
Offset - 45
CB - 63.4

 

You will have no problems downsizing to stock JLR 18" wheels for a 2010 XFS, as 18" is what they came with from the factory.
How do I know?
Coz my first Jag was exactly the same as yours, a 2010 XFS, and it came with 18" Venus wheels.

 

Thanks a lot for the feedback. That means that the set on the picture will fit my Jag. The brakes are upgraded to Brembo ones, so hopefully that's not the issue.

 

Don't remember the specs on the different models, but I recall there were three different sized brake rotors available on the XF in the US, depending on the trim level. The four-cylinder came with the smallest, the 5.0L came with the middle sized and the Supercharged and R trims had the largest. I might have bought a Supercharged except for the wheels. I bought a Portfolio which came with 19" wheels because I wanted the adjustable lumbar seats, and then immediately ordered some 18 inch wheels. In the month that I was waiting on the 18" wheels to arrive, I creamed one of the19" wheels and had to have it repaired. I seriously considered finding a wrecked 4cyl model in a salvage yard and scrounging the smaller brakes so that I could even go down to 17" but I've lived with the 18s for a long time now and only had to have one 18" wheel repaired in 8 years. This "vanity-sizing" trend in wheel styles needs to come to an end. Its one thing on a pure track-car but really, anything over an 18" wheel is impractical. I don't know about Ireland, but here in Texas, the only reason they pave any roads at all is to keep the dust down. It obviously has nothing whatsoever to do with providing a smooth surface to drive on.

 

i completely share your opinion anything over 18" is useless in everydays life... But getting the big wheel sensation from the supercars make people to upgrade unnecessarily...

 

The three different XF front brake specs are base model 326 mm (not sure if NAS ever got those, maybe 4 cylinder only as pdupler says), V6 and NA V8 355 mm and SC V8 including XFR 380 mm.
17" OEM Jag wheels will fit over the 326 mm brake rotors but not the 355 mm let alone the 380 mm.
18" wheels will fit over the 355 mm but not the 380 mm.
19" wheels will fit over the 355 mm but some will and others won't fit over the 380 mm, generally the early 19" won't fit but the later (eg F-Type) will fit.
20" will fit over all of them.
