Inside OR outside wear is an alignment issue

Inside AND outside wear is pressure too low

Centre wear is pressure too high

There is another alternative explanation and that it that the tyre is too wide for the rim-width (say a 295 on an 8" rim)

If you reckon you are setting the pressures at 35psi, then check pressure with several other gauges as the gauge may be reading low and causing over-inflation.

Finally, if the pressure is high AND there is excessive toe-in, what you see could also occur.

Check your pressure gauge and get the alignment done anyway - as those tyres are toast and need to be replaced
