Safe front tyre max pressure

Hi all, just wondering what pressure you can ACTUALLY run street tyres at?

I have 165/80 R15 on the front of the Dart and they say 40 psi MAX. Do we think this is for road grip/handling purposes or "dont go any higher or they will blow up in ya face" reason?

Any thoughts would be great, cheers

You can safely run at the max pressure on the sidewall, there will be a safety margin built into that figure before a good tyre would burst. Some tyres also have a max pressure on them for seating the beads as well. I have always run skinny front tyres at 35psi without issue on the street or the track.

Hi James, I think it also relates to the load rating of the tyre, ie the maximum pressure at the maximum load for that tyre.
