Like Rob K, who I often agree with
I too have in the past just checked the top bit of the tyre with my gloved hand and looked at the bit poking out the bottom of the mudguards, now I check the whole tyre, but as our spray suppression is limited to a single mudflap that’s easy, although I still don’t pull forwards to check the bit on the ground, I don’t need to with my unit as I’m the only driver and it has new tyres, so I’m safe in assuming they’re ok as long as I don’t mistreat them.
Although I have no patronising remarks to make to ebabes, there is a way of noticing if a trailer has tyres with flat spots, that is by listening to it going down the road, flat spots will give a whump whump whump kind of sound as they contact the road, if you know what I mean
I smoke and drive with my window cracked down a couple of inches so I hear that kind of thing, in fact I had four pairs of tyres moved in relation to each other because of such a thing at the beginning of the year, I did it to prevent wheelbearing and brake component vibration, the tyres weren’t bald, although I knew they had flat spotted because I hit a deer which ripped my airlines out from under the trailer, locking all the wheels at 70mph, but all the same, you can usually hear the noise, if you do, jump out and check the whole tyre, if you haven’t already done so, especially if your shunter is a lazy [zb]

I do agree about the flat spots, and the noise, you can normally even hear a slack tyre. The late great (to me anyway) John Williams called out on the CB one day that one of us had a warm tyre, it turned out to be a driver following me and John had picked up the scent. (Desert Training I presume
) I always carried an air line and within a few minutes we were back on the road.
NMM also mentioned the spray suppression. Well what if your whole fleet is fitted with Cats Whiskers?

No mention on the Cats Whisker site about how difficult it is to check tyre tread or cuts in the surface.
It has been a good thread with mucho senso talked 
Apart from this PRAT.

Mr Walter Cox, transport engineer of Joshua Tetley & Son says he has found the system very favourable. This is what he says:
“The drivers have commented that 20/20 Cats Whiskers makes the rear view much clearer. The plume of spray is kept down which aids visibility and keeps the lorries much cleaner - particularly the canopy sided vehicles - it improves the image of the vehicle and the juggernaughts as a whole”
