Oooh both
Here's a couple, but what angle do you want? Sadly working today, it will have to be later...
I assume that it you were fitting 245/45 both front and rear that you would have the same width wheels front and rear. So maybe 9j.
If that’s the case then the rears would sit slightly deeper into the wheel arch but the tyre/wheel interface look would be very similar.
Those in @Mark Peo pic above are 245 on an 8.5j wheel at the front. The rears are 275 on a 10j wheel.

I’ve just had 4 x Goodyear F1 Asymmetric 6’s fitted in 245/45 r20 (load 103) fitted. Replaced the hedge finder 275/40 r20’s that the converter fitted. I will take a pic later, if you still need one?!?
The ride and handling is miles better than before, when running the 275’s all round. Mind you, the new tyres are a premium brand, whereas the 275’s were not. No rubbing at all on Bilstien B14 Komfort suspension.

Do you have staggered wheels or the same width wheels front and rear?
Same width wheels front and rear, 8.5J. 275’s, IMO, are too wide for an 8.5J wheel, but a lot of converters fit them anyway.
Absolutely they are. I have 245/45 on my 8.5J fronts after replacing the 275/40 and the difference was massive.
Yes please
Cheers. They don't look much different to the 265's i have on.
Was just looking into tyre options for when mine need replaced.

Why do people fit wider rims / tyres on a van? I guess purely looks? From my perspective and my motor racing experience it has zero advantage to any handling characteristics. A van on a really good suspension set up with narrower rims and 40 /45 profile tyres will handle way beyond most drivers capabilities on the same size all around. Comfort is always compromised with really low profile tyres and wide rims that are not designed for a van in the first place. I love to see the show vans they look amazing. Each to their own. Enjoy 
I am sad enough to think they look cool AF. And I'm not talking about Adrian Flux...Why do people fit wider rims / tyres on a van? I guess purely looks?

Yep that’s about right. I like how it looks and if I want to go fast I’ll go out in the car. It’s a trade off with regards to the comfort, but just done 1600 miles in 11 days on a Scotland trip without any comfort issues.Why do people fit wider rims / tyres on a van? I guess purely looks?

For me it as more to do with off road performance BFG KO2 255/55R18 109. I look up the recommended rim size and try to fit that size and definitely within that range. I tend towards steel rims far cheaper from new. I am interested in off road grip, clearance and ground pressure. Automatically on changing to this size from standard my recommended pressures for on road went down significantly which also has a bearing on off road performance and floatation. In the winter or after prolonged rain I will air down depending on how soft the ground is but have had then down to 6psi over very wet periods. This saves damaging the grass surface so reducing breakthrough and mud and one just uses minimal throttle to prevent spin or slip though sometimes once the way has become slippery and muddied I might have to press on with speed and maximum aggression just to get up the hill, private land ROW. I am not interested in ponsy looks. If I was not off road I would just use normal tyres with the best on road performance and comfort. I look aghast at those fitting stretched tires over inadequate rims and ridiculously low dropped suspension with bottoms scrapping the road like dogs with worms and scratch my head with those trying to attain the rugged muddy look by fitting off road tyres and yet never really venturing or need to venture off road. To me its like looking back in history at a Black adder scene with guys wearing ruffs and make up constantly looking at them self in the mirror with pure vanity and fussing about the slightest blemish. It feels like a Salvador Dali dream or nightmare.

Mine isn't lowered and I often use it off road (to a far lesser extent than you!) but it is probably fair to say that your circumstances are fairly unusual, few people need the ability to negotiate the type of terrain that you do.
So while I'm not into the lowered scene I do enjoy reading about those who are, and the wide range of suspension / wheel and tyre set ups that forum members use.
As they say, horses for courses!!!
If you want to see one in person and are anywhere near Shrewsbury, head down to salop vans. I think they fit this size of their vans as standard
Or… if you’re ever in West Yorkshire and want to see 245/45r20’s on a van, let me know
