Has anyone had an engineer’s certificate done on a vehicle with larger tyres than standard. If so did they have to up the capacity of the brakes or anything else?

Any contact names or numbers Melbourne for this would be appreciated.

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.

oh and a tip. Call every certifier on the list. If someone sounds "to technical" forget about that certifier. You want the layed back bloke, you'll have a much better chance.

Im in the process of loading a big block into a MQ patrol and finding a certifier in my area that really could give a krap is like lotto :)

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.

Truckster,

Know what you mean about hard to find anyone rang about 5 so far and none of them will do it. I'm only talking about 265/75/16 or 33/10.5 nothing to radical.

Roughly what sort of costs are we looking at for a certificate? Can you give me any company’s to try next, were did you get yours done?

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.

They would use a Vicroads engineer, they wouldnt do the certs themselves.

thats how most 4b shops work.. wish it was that easy.

Lots of engineers will work in with the stores, and know and trust their work, but the same engineers wotn go near work the back yard dude does.. they never know what they are gettin into
