Hi does anyone know if the 20" Hydra alloy wheels from an HF will fit straight on to my 2010 Jaguar XK all four wheels are 8.5J with 255 tyre width and aspect ratio of 35.I realise the rears should be 9.5J but would these be ok ?
Thanks

Sorry meant to say XF

 

The fronts will definitely fit, I've done it.
As for the rear, https://www.wheel-size.com/ indicates that they should also fit with room to spare.

 

Thanks I have checked the site and it only shows 9.5 or 10 for the rears on 20" wheels so still not sure if I should fit 8.5 the wheels look great but dont want to buy then find out they are not suitable.

 

You're asking for trouble if you buy 8.5" wide rear wheels for a 510HP XKR. There are lots of OEM 20" wheel choices that'll fit with no problems.

 

I am running the standard 5.0 not the XKR don't know if that would make any difference as not as much power going through the rear wheels

 

I'd not say 420 horsies is "Not Much" though.

 

Fair point

 

The 5.0 XK is only 385 little ponies, IIRC.

 

Ah, *****. I was thinking of the 4.2 XKR. My bad.
Still though, 385 is more than 90% of all vehicles.
