Thread: van tyre wear pattern.

Is the van loaded evenly from side to side? My gut feeling is that is has to do with axle alignment. The axles have a fair bit of slop in how they sit over the spring bolts, and the springs themselves never seem to be perfectly matched in terms of centres. You might be able to check this by climbing under and running a tape measure between each axle, with this being done on both sides and compared.

Are they worn more in the centre, it's a bit hard to tell from the photos. I don't run that high on my van, 3.2t loaded. Remember that 3t is only 750kg on each tyre, less if you deduct the ball weight.

The tyres look over-inflated which isn't surprising at 60 psi. Consider the pressures that you would use in your car's tyres if it was loaded to the same weight. My 2.5T van's tyres are 36 psi front and 38 psi rear.

The maximum pressure stated on a tyre is for maximum load at maximum speed for a short time at a specific ambient temperature, which I can't recall specfically but feel that it's around 30 mins.

Caravan Tyre Pressure; what should you be running?

Keep in mind I am not a caravan owner/person etc..

As others have already mentioned, 60 psi seems way high, I would have thought round 40 - 45 psi, my first thought when you said "van" and read 60 psi I thought van was like a light truck.

But on saying that, outer wear in general terms on both sides is under inflated, if its just on one side, I'm thinking axles alignment is wrong/out.
Also a up down type wear can be worn or shocks that are not upto the job.

I had some uneven wear on my van tyres and found one of the dual axles wasn't aligned very well. I loosened off the axle clamps and was suprised how much movement I got.

What’s the load rating on the tyres?

Its pretty incredible isn't it. They can be a long way out, I'm really not sure why they make the axle pads with so much slop in the them. If the van is always trying to turn then they will scrub out the tyre edge like that.
