Not really, there are secondary springs within most airbags, obviously I don't know what traction type it was. Deflated air suspension usually gives quite a lively ride and is often accompanied by a reduction in maximum permissible speed (say, on Sprinters max 45mph) especially if the affected vehicle is carrying passengers. If the affected vehicle is locked out of public use the max speed may be higher depending on traction. The actual instructions vary from TOC to TOC and for different traction. Most Sprinters etc are 45mph max with deflated suspension if in passenger service, up to permissible speed if affected vehicle locked out of use (Northern have an instruction for 156s which are still max 45 even if OOU, due to slightly different emergency springs apparently).
There are often a couple of other considerations for deflated air suspension at least on Sprinter type stock - brake cylinder pressures are high due to the load weighing system on the unit thinking it is fully loaded, and when coupling to other units.
