4Matic GLK on the beach?
What you think?
Thanks in advance,

he didn't have any




I have 20" wheels and if I'm taking my car into the desert, I drop the pressure down to 19psi from 34psi. So for beach driving, I'd advice dropping down to atleast 25psi which should be sufficient. But do take care when your driving your vehicle back onto the asphalt because you can damage your tyre if driven on a hard surface due to low tyre pressure.
I always carry two compact air compressors (with the 12V adapter) with me and a pressure gauge. Before I get back onto the tarmac, I make sure that the tyres are refilled to 34psi. I'd recommend you purchase these as well, it will come handy.
The air compressor does come as standard in the European Models as well but I've never used it as it seems to be underpowered but I'm only judging it by its size. It might be appropriate for the space saver wheel but im sure it would take a lot of time to fill in air. I use a black & decker air station unit which tops up the 'tires'
from 19psi to 34psi within 4 minutes. Heres a link to the product : http://www.blackanddecker.com/Produc...roductID=15542Does a decent job.

The whole idea of deflating tires is to have sidewalls to add to the contact patch, which in turns decreases amount of pressure put onto the sandy surface by the wheels. 20's have very little sidewall to flex so the benefit of deflating them is probably negligible.
Picture for reference:

True, theres very little sidewall to flex but the reduction in pressure even on 20s does make a big difference. When on sand, you immediately notice that you tend to bounce less, the ride becomes smoother and you simply sail through sand. Trust me, its not negligible.
I can vouch on this out of experience. I have 235 45 R20 in front and if i remember well right now, 255 40 R20 at the rear.
Good post NYCGLK. When on sand, the idea is to get the maximum tread foot print of your tyres.
We own a place down there.... it's getting a little over crowded during the peak season but still nice in the off season when we usually go.
Have fun!!!
