Default 1974 beetle recommended tyre pressures

I have a 1974 Beetle classic, 1600cc engine.

On the front I have 185/55R15's

On the rear I have 195/65R15's

They came with the car, which was lowered and now set back to regular ride height.

I am looking for recommendations on the correct psi for these tyres on this car front and rear.

Thanks in advance.

18 psi front 26 psi rear. The tyre size does not affect the tyre pressure required

If you use standard tyre pressures you will experience uneven wear and sub-optimal grip. See my comments a few posts back.

Wow!! Glad I found this thread, my 60's bug on standard 165/80's was running 30 PSI all round (had them fitted off the car at National Tyres...they obviously didn't know what they should be....) although they knew I needed fat valves...which was good

I thought there was something very wrong with my steering/steering box etc, very skittish and very light, it felt un-safe, and wandered everywhere!...But maybe the pressure was way too high, 17/18PSI seems very low, but it must be for a reason on the bugs.

Tyre pressures generally relate to the weight over that axle. In a beetle there isnít much weight over the front axle hence the low psi

Right, of course makes sense, I rarely put more that £5 worth of fuel in my tank, so not heavy at all over the front - so 30PSI in the tyres, this would make the steering extremely light, coupled with the low weight....??

I know those pressures are correct but I've never run mine less than 25. Just seems unsafe to me! And not much warning if you have a leak b4 you run a tyre off the rim which my sister did in her 03!

Reduced my fronts to 17PSI, and Rears are at 27PSI - My goodness what a difference! Car feels great now, front seemed disconnected completely when I was running 30PSI!!! Constant steering adjustments at speed, was scary tbh, Feel like an idiot now

Nonsense.
