So a little insight to my almost weekly routine

, being an ex-motorcyclist

I'm very keen on carrying out weekly checks on my car, especially when it comes to tyre pressures.
I think I have a porous alloy wheel, as every time I check my off side front the psi has dropped to around 22 - 25 psi. It never goes lower, and I've had two tyres and two valves do exactly the same thing.
The wheel doesn't appear to be cracked, and it's not bent or oval, actually the overall condition of the wheel is pretty good apart from the odd bit of curbing
I'll either get the wheels refurbished or just put up with it until my lottery win happens

then I may get some new wheels.
Overall the car is still going well (famous last words) and I'm still pleased with it.
