Engineer's certificate for tyres

If you call Vic Roads they will email you a list a engineering certifiers in your area. Contact the certifers and they have all the details on what will "pass" or if you need a cert for your upgrade.

Yes I have had mine done.

You will have problems finding people to pass them at the moment with the "CHANGES" supposed to be coming in any time now. Numerous people are trying to get them done..

They run a brake test on the truck, it all depends how good your current brakes are. If they suck, you will have to upgrade them. I'd probably go with Braided lines for a start which is cheap and you will notice the difference.

You also need to lengthen your mudflaps so they cover more than 50% down the size of the tire,

eg.. at least inline with the axle line.

Had it done last year in conjunction with an increase in Gross Vehicle Mass, its still the same for tyres only as it relates to weight,speed,braking on the upgraded tyres.

Tyres, weight and brakes at specified speed monitored by computer is the test.

(1) The vehicle is ballasted up to GVM on compliance plate or GVM sought.

(2) Tyres you want rated have to be fitted

(3) Test hand brake on VICROADS surveyed hill with the engine running, hand brake on, clutch out and foot off the brake. (Photograph it)

(4) Turn vehicle around and stop opposite where (3) above was conducted and conduct said test again facing the opposite direction.

(note: if vehicle fails this test the whole shebang is terminated and you blow your fee)

Fit computer monitor which is activated by rear brake lights. (Note: if defective, test cancelled immediately and you blow your fee)

Then conduct brake test as follows.

(1) Must pass/comply with speed distance stop over set distance and with two passes in opposite direction.

(2) Front brakes disabled and once again two passes in opposite direction

(3) Rear brakes disabled and the same as above. (This is a bitch as the front locks up if you are not careful).

The road sector used is the same for each brake test.

Pass all that and you get a new tyre placard.

there is a 4x4 joint on just of cooper street in epping that do the work and supply the engineering certs as well. i know a couple of the boys from our club have mods done to their comp 4bys and they did the lot
