The mind boggles how you can even post such statements!
I think he was talking about the maximum limit printed on the side of the tyres. IIRC, they state you should not exceed 50psi.
Can I kindly suggest you actually read the full text on the side of the tyre to which that comment relates to! I'll give you a clue - it does NOT apply to the UK or EU.
I think the confusion arises about the 50psi:
- is it 50psi when the tyres are cold?
There is absolutely NO confusion. Tyre pressures (on tyres for highway use, so not 'specialists' such as F1 slicks, or Dakar sand tyres, or whatever) should ONLY be checked when the tyre is cold, and at the ambient air temperature. You can read every handbook or workshop manual on the planet, and I'd strongly bet that it will categorically tell you NOT to check (and more importantly, adjust) tyre pressures when the tyre is hot. And just to clarify, a tyre can heat up in as little as half a mile.
or
- is it 50psi max (which means that potentially 50psi could be reached and breached if the tyres are say at 48 psi and then the pressure increases due to temp when driving)?
Tyres are categorically and specifically designed to cope with increases in pressue as the tyre heats up - and they have absoultely MASSIVE threasholds for 'overinflation'.
The 'dangerous' scenarious which can wreck a tyre is excessive heat, and NOT excessive pressure. And one of the primary causes of excessive heat in a tyre is too LOW a tyre pressure.
I've regularly inflated road-legal tyres to over 140psi - and have NEVER had a tyre fail due to over pressure!
Sadly, there is some clearly very serious cases of uneducated and/or 'old skool' 'head in the sand' opinions regarding tyre pressures.!!
