Dynabeads

Just wondering why Dynabeads sell a 'standard' size and a 4x4 size?

As I understand it the 4x4 bead is a bigger size. So is the difference in size to enable the 4x4 driver to air down the pressure (for offroad work) without the beads blocking or coming out the valve?

Also, I've heard reports that if driving with Dynabeads and you hit a pothole they temporarily don't work. I wonder if this affects the smaller beads more or less than the 4x4 beads??

2008 Defender 90 Puma 2.4 XS CSW Stornoway Grey

Mixed reviews but generally very good.

If the valve is at 12 o clock none of the beads would escape if deflating. I have the 4x4 larger ones just for convenience as it was a new set of tyres going on.

Be wary as different providers recommend different weights and some people have not had success. I went to Dynabeads.co.uk and whilst perhaps more expensive than Devon 4x4 the charts differ for certain sizes by up to an ounce per tyre.

Thanks for the tip

Yes I feel that I will go with Dynabeads themselves. Probably safer to err on the side of too many rather than too few beads.

I will be using 35" tyres on mine so hopefully the beads will be up to the job. Time will tell I guess.

How have you found them to behave if you are on a rough road or hit a pothole?

Once fitted I had a slight vibration at 50mph only but the tyre fitters had inflated all the wheels to 36psi. Once I lowered the fronts and raised the rears the issue has vanished. Potholes I try to avoid and with my 305s it'll have to be a biggun to affect vehicle trajectory. I am glad to be rid of all the stick on weights I used to have as they look extremely shabby after time.
