Checking 275 wheel clearance on the XF

Recommended Posts

Hey team,


About to fork out for a set of the below for the wagon.




They only do a 10" and 8" option for the V51s. Naturally I want to go as wide as possible on the rear, which (for me) means 275. I'm keen for a stance like the below with a 25-30mm rake and some guard clearance at the rear.  Photo credit to ford muscle cars instagram account.





I used an online calculator to see what I had to play with (look at the 'new' figures) when running a 275x35 on the 17x10 rim (0 offset):



I made up this highly engineered and precise measuring tool, which uses the diameter above, 275 tyre width at 0 offset and used it to test inner and outer clearance.



Result was a 6mm clearance to the top of the outer guard which includes a someone 'organically' rolled lip (aka rough as guts) and a 20mm clearance to the closest point of the inner guard.

Inclination is to run with a 6mm offset to gain a little more clearance to the outer guard, and about 50mm of suspension travel before guard rub becomes an issue. I'll be running 17x8 on the front with 235 and 0 offset, which don't seem to present any issues with a lowered but otherwise standard suspension set up.
