Left rear tyre loses pressure

He mentioned he's in Belgium, I don't think many of the replies were considered with that in mind.

Overall, yes, going high speeds and subjecting your tires to lots of shear forces will probably mean that the tire might and most likely will:

1. completely depressurize and be damaged to the point it must be replaced
2. fail catastrophically at high speed, either flying off the wheel or tearing into pieces
3. roll right off the wheel during a hard turn
4. deflate too much and be damaged before the race, causing you to replace it anyway

Either way, it will most definitely ruin your race weekend, and possibly endanger your life.

Get it looked at and fixed!

Then you can drive all you want without damaging the tire, wheel, suspension, car, or yourself. If you crash, nothing said here applies.
