Having a time finding aftermarket wheels in the 285x30x20 for my 2009 XF supercharged. I have seen a ton of opinions on going to 19" but the manufactures say they will not fit. Yes or No?
Seems there are a lot more choices in the 19" over the 20"

Any guidance would be appreciated.

 

It depends on whether you have the 380 mm front brakes or not.
If you do OEM Jag 19" wheels will not fit over them (except for F-Type wheels) and very few after-market 19" wheels will fit over them.
If however you have the 355 mm front brakes then all OEM Jag wheels 18" or bigger will fit and the same with almost all after-market wheels.

 

Thanks so much. May sound sill but how do I tell the difference?

 

Several ways to pick them apart:
1. Look down the bottom/side of a caliper bracket, it will have either 355 or 380 embossed into it.
2. Measure the diameter of a rotor/disc, no need to be perfectly accurate a ball park measurement will be close enough to tell.
3. Just look at the shape of the caliper brackets from straight on, although the 380 mm brackets are bigger and longer they are skinnier than the 355 mm brackets.

 

Thanks again----great help for this 75 yr old geezer

 

one more then I will go away---for awhile.
Too old to get down and look at the rotor but the installed replacement rotor are 326mm = 12.834"
Otherwise I will take to the garage and have him look.
Thanks in advance.
