I'm a mountain biker at heart, and have wondered why the mountain bike model of different tires and widths for front and rear tires hasn't really been adopted with GG. What are your thoughts?
I run WTB Nano 40's today and love them. I'm eyeing the Panaracer Gravel King SK's and think 35's are what I need (they commonly measure 38), but why not 40 in the front (they commonly measure 43)???

It's another tradition to overcome. It will happen in time I'm sure.
All depends if your setup will allow it though. Nano 40s are the absolute limit at rear on my bike, but I can go a touch taller/fatter up front

For me it's a matter of economics. In my opinion there's not enough benefit to running a wider front in this application to justify it. I prefer to rotate my tires from front to rear a couple times through their life so they wear evenly and I don't have a pile of half worn out front tires laying around. Mountain bikes are a special purpose machine. Everything gets optimized for the offroad environment. Gravel and CX bikes tend to spend more time on surfaces that aren't bumpy or loose traction wise, so there's less benefit to having a wider front.

What benefit would it have on road/gravel? I don't find myself ever thinking that I need a fatter tire up front when I'm grinding away on the dirt roads or on pavement. I'm perfectly happy with 40's front and rear. If the front end of my gravel bike was washing out often or I was getting a lot of rim strikes...I'd start to look into it. But I dont...so I don't. It can't hurt to experiment if you are inclined to do so. But these are different machines. I don't think there would be the same benefit as there is on a mountain bike.

My $.02: I'm not a tire engineer -- and the design and manufacture of tires is quite complex. That being said, the demands on front and rear tires are significantly different for gravel riding. And this concept is further complicated by the fact that frame and wheel design also affects the type and dimensions of the tires which can be used on a specific bike. In the past Continental marketed front and rear specific tires for road bikes. I never tried them. And I believe that this concept never gained much traction (no pun intended) in the road market. So, I hope that some tire manufacturer takes a serious look at this question, and tries to develop front and rear specific gg tires.

I am thinking of trying it. Old school mountain bikes had different front and rear tires as a set.

Currently running with G-One 650x40 and because I have a Slate I can go to 650b x 47 Elwood on the front...have never done this and was about to pose the question...and here it is on the forum...even though I have the Lefty up front it would provide even more of a supple ride in rough conditions..any others tried it...thoughts...?

As bobknh mentions, tire design and manufacturing is quite complex. In my extended experience, the end sales of separate front and rear tire have never justified the resources required to design, engineer, tool and develop for commercial use. Once you call a tire "front" or "rear" you're going to sell about half as many as you would if you just offer a tire. A smaller niche like Gravel amplifies the issue. In addition, I've seen tires designated front- or rear-specific used on the opposite end of the bike quite often. Maxxis has considerable experience with the DHF and DHR tires both run at both ends.
In the end, tire companies can recommend tires for front or rear applications, but the consumer has the last word with their spend, as RunsWithScissors clearly states.

Well, at least one fairly accomplished rider is doing it:
