engineers cert and 35s on 8's

[derangedrover]

Are claws the only tyres that you can get cert'd on an 8" rim as they have a letter from the manufacturer?
What about MTR's?
The engineer I usually use said no to a 12.5" tyre on an 8" rim and also said no to that tread width on a rangie citing it wasnt heavy enough for that much tread and wouldnt meet the minimum contact pressure requirements?
How are people getting around this to avoid defect notices?
Any advise appreciated.

Cheers
Daryl

Lohnings (Sp) certified my 35x12.5 yokohama's on 8 inch rims


cert doesnt mention tyre brand though

now has 35 x12.5 MTR's so cert still applies in my eyes

ive got 35x12.5s engineered on 8s no worrys :wink:

i got pulled over again the other day by the cops and they said my tyres wernt legal................... then looked at me papers then said no worrys see ya later

[taziiy]

this might sound stupid but i didnt know you had to have a engineer cert.
for wheels and tyres

[GRUNTLESS]

im thought you did if it was a larger then standart tyre size

it doesnt mater any way it costs no more to get them done when he's checkin the rest of the sh!t :wink: ............. it helps keep the piggies off my back as well

[MKPatrolGuy]

From memory you need to engineer them if you increase the diameter by more than 15%

[taziiy]

i bought my lux about 18 months ago it has body lift and suspension and did have 35/12.5/15 s it has 31 s on it now for the road it never come with a certificate should i get one

You do need to engineer 38 inch tyres, don`t quote me but anything over 2 inches in dia or width from standard is classed as illegal. claws are the only speed rated 38 for sale "i think" but a lot cars have been engineered with all types of 38 but nothing over.

Daryl, which engineer are you using??
Try John Wilson
KZ Engineering
6236 3009
0417 230 074

Wendle,
Thanks for that. Spoke to John this arvo and all is well, apart from the requirement to strap 200lt of water in the back seat and drive around in circles etc......but no probs with what I want engineered.
I was speaking to Ray at Canberra Motor Works about it initially and he really wasnt going to come to the party, knows his stuff though, I suspect he just didn't want to be involved.

Cheers
Daryl

yeah, rego are getting tight with what they want on the reports. I have to put 300kg of stuff in the back of mine and drive the slalom course at the police driver training centre..

As far as im aware wen u go to n engineer they do right the size tyre being used but that duznt mean there covered ( I think u were lucky travis) legally cant run 12.5 " tyre on 8" rim needs to be 8,1/2" which is illegal in aus ,if u have trouble believing me ask hypolux bout it he got his truk engineered with 35"s got pulled over and asked 4 cert ,he said fine here u are N the coppa said u do realise your tyres are illegal he got off with a warning, and im sure same applies to 33"s if there 12.5.

anyway its my .02c worth i could be wrong (i have b4)

Dan

Ps with my new new truck im still gunna run 35"s and run the risk unless i can get those 315's that the shedguy is gettin in from the states...............................................in mtrs

[GRUNTLESS]
