From the guys that did my graphics! Was much easier than colour coding em, I think it turned out well:D
 
Oh my god tyres again!
225/75/16 as fitted to mine
View attachment 39696
225 is the width in mm
75 is the profile which is a percentage of the width so it varies in height depending on width
16 is the rim diameter in inches
Did you have to trim the arches with those? I'm asking as I have 215/65/16 currently and want to put that size on. Would the 225/75/16 be ok?

Diesel Do doesn't get on here too often these days.

Arch trimming won't be needed, as the arches aren't the closest thing. The spring cup is the point where large diameter tyres catch first. ;)

The size your asking about has a diameter of almost 29.5", which could well catch on the spring cup with some brands of tyre. This could be overcome with thin shim spacers, between the wheel and hub. You'll need to inform your insurance though, as the tyres are larger than a standard fitment, and some insurers don't like spacers.

Looks like 205/80/16 are as big (tall) as you can go:
On a FL1 the biggest 16" you can fit is a 205/80/16. These come within a few mm's of the lower spring seat F+R as they are about 2" bigger than standard (giving an approx 1" lift). Check out TYRESAVE: Tyre Size Calculator to see which 17" equivalent would be the same outer dia, but you probably wouldn't be able to go any wider without being slightly smaller.

It'll be the spring cup that is the limiting factor, and the 225 section tyre will likely catch it at that diameter... (at least, without spacers, or using a wheel with a different offset)
