Tyre deflation warning system malfunction

Whenever I travel at more than 70mph in my Honda CR-V the the tyre deflation warning system goes off. I asked for this to be checked at the first service but I think they just reset it and the problem persists. Any ideas?

What happens at speed is that tyres heat up and that can raise their pressures by as much as 5PSI. If the pressures are slightly uneven and one of them raises above the critical point set in the TPMS, then that will trigger it. I know. Happend to me. And I had to puzzle it out.
