Well I guess I'll just keep repeating myself;
if you need chains for traction get the Aquiline Talon style.
There is no comparison of this style of chain for traction and ride quality.
On frozen ground or snow pack the traction will be almost the same as hard gravel or even better,
The ride is the best of any style of chain,
at low speed it is no different then rubber only,
at high speed you will hear noise on dry pavement, no bouncing or jarring.
For those that wish to run front chains on some of the smaller tractors look at utv/atv chains
in the same or similar patterns.
The clearance of the Euro style chains is the same or sometimes a bit better as any others.
As far as chaining up just the front;
yes it could put more wear on the front.
However it would not be loading or working it any harder then using max force while
digging or carrying heavy loads on hard surfaces in the summer.
To my thinking the conventional style chain with its grip and slip action and
vibration would be rougher on the front axle then the Euro style.
Also a great many people seem to be concerned about the side loading of their front end loaders,
add chains to the front and you will increase it more.
I normally just run rear chains on my snow removal tractors,
if a major ice storm is forecast I will often get out and mount the fronts,
If my front end is getting pushed I'll just use a bit of brake steer.
