Yup, as Wayne says, make sure you enough wavey washers and make the pivot
assembly tight enough so that there is no shimmy. But not too tight, or you
won't be able to steer.
I have seen this over and over again with new amphib installations, where
people quickly wear out their front tires because of the shimmy. I have
almost 500 hours on mine, on pavement, and still not worn out, so they do
last if set up right.

John's on amphibs!
Pressure is right John @ 45psi. Make sure the front pivot is constantly
greased so the grease acts as a dampner for shimmy. There doesn't seem to be
a right and wrong in regards to the "wavey washers" being too tight.. or too
loose on the pivot shafts.
Another option that has been tried, I'm told successfully, is to mill the
pivot shaft attach block with a slight angle on the bolting face. This will
let the pivot shaft "trail" slightly..... like I like on tailwheels to get
them to behave.

First thing I would do is check the alignment. Measure the distance from
center to center across the front and then across the back. As far as I
know they should be the same otherwise you have too much toe in or toe
out, either of which will accellerate the wear.

everyone, 295 is back in the air at least for the climb test which should
complete the paperwork. My son and Garry were the lucky ones - I have yet
to fly it - just doing all the work!! SOOOOOON> Question I have is the
front tires - put new ones on before flying and after about half a dozen
TO & LDS the centre ribs of the tires are worn off much like the ones I
took off. Using about 45 lbs of pressure. Too much/too little/ wrong
tires - Any thoughts on this one??> > > > John Peterson> > >
