Single speed horizontal dropout lock nut position?

Hi guys,

I just put on a pair of 700x25c tires on my single speed commuter bike(Langster). I found I had to move the rear wheel back about 1" to make the rear tire clear of the rear fender. I was running 23c tires before and the axial was sitting at the mid point of the drop out. So right now the lock nuts sit at near the opening of the drop out, but not hanging off the drop out. The lock nuts still have all the surface to clamp onto. If I remove one link of the chain to bring the lock nut back into the drop out a little, the tire would rub against the SKS road fenders.

So with the current position is it safe to ride? Both side lock nuts are tightened down.

Thanks!

AX.

FYI:
The word "locknut" is commonly used about a nut being tightened down directly against another "nut". Like the cones in a cup & cone hub.
What's in your pic is an axle nut/wheel nut.

I have a Langster of the same era and have also experienced some issues with the rear tire clearance. I cannot run tires larger than 23 mm without moving the axle backwards in the dropout, otherwise the tire will hit the bottom of the brake near the brake bridge. Riding with the rear axle in the position shown is just fine; I prefer the axle being closer to center, though, as it effectively shortens the chain stay for a theoretically more responsive feel.
