Sorry for the delay in getting to this thread...busy, busy, busy. :-)
Noone produces a BTR-70/80 wheel that is not just a modification of the DML offering in some fashion.
SP Designs offered the "spider hub" verison years ago, long OOP now.
Otherwise it is just the 'armored" and "open" hubs as mentioned.
I have spoken with Sergej at length over this and not only does he hesitate to basically have to master the two wheelsets from scratch to get the proper look, but he also says that the "bulging" fat look is only present when the tire pressure is low. He says that by his measurements from military expo shows, when the wheels are at higher pressure, they measure out close to what DML offers. Go figure...

My guess is that unless someone makes a new tool BTR-70/80 kit, no new wheelsets will ever emerge.
Oh, and by the way, the Zvezda wheels are BETTER than the DML rubber ones in that they are made of some harder plastic rather than the problematic rubber. So you may prefer the Zvezda offerings. At least from my look at the BTR-80A kit I have.
