Outer Limits 4x4 Board

Are simex centipedes (extreme trekkers) bias ply?
Have heard that bias ply r not road legal and I might get sum.

yes they are bias ply

unless they match or are greater than the size/speed/load rating on your tyre placard in your vehicle, then they are illegal

like chops said but also your vehicle must have been manufactured with bias ply tyres as was the 60's for example. if your vehicle has radials the rta will cane you if caught and you'll void ur insurance if it gets noticed.

Thanks guys.
No mine didnt come out with bias ply tyres.

So would my insurance be void if I only used them on unsealed surfaces (public or private) or is that something I could get agreeance on with my ins. co.?

You'd have to talk to them, find out when they'll cover you when you go offroad

one place I asked wouldn't cover me if I went to a designated 4x4 park..

Who was this?

I was with Suncorp a few years ago (actually, I still am) and they sent out an amendment to their Terms and Conditions specifically stating that a designated 4x4 park was not covered. I rang them as I still had about 8 months left on the policy, and they said I as covered up until expiry, but wouldn't be upon renewal. So, I left the phone call by politely saying that although all my insurance was with Suncorp, I would have to look elsewhere come renewal time as we camp alot at designated 4x4 parks (LCMP).

Anyway, they must have had a few similar phone calls as by the time my renewal came the policy was put back to specifically include 4x4 parks, just not competing in any timed events, scored events, etc, etc. I rang them to double check, and as far as I know I am still covered in a designated 4x4 park for general driving, just not comepeintg.

So, just interested in who told you that 4x4 parks are not covered by them. Hope it wasn't Suncorp! Please say RACQ!

Don't know where you are but in Vic that's not the case. As long as the tyre meets the placarded load and speed rating requirements they may be bias or radial. If they are a Winter tread tyre on a 4wd vehicle then the speed rating can be as low as 140km/h even if the placarded speed rating is higher. This was the answer I got to an email sent to VicRoads asking some questions.

You're more than likely going to get a larger size in tyre than allowed on your vehicle anyway. Therefore they will be illegal based on size.

I'm in South Aust. I haven't checked the latest regs. of mods. for here but I know the most recent Code of Practice for 4x4 mods allows a max. of 50mm larger diameter tyres than OEM.
Think I will chase it up before discussing it with the ins. co.

The Rodeo Sports (R9 series) came out with 31" on 16" rims I think, I am only after 32-33" muddies so I think I'll be within the regulations.
Can only go up to about 10.5" wide in that diameter too on mine or they'll rub in the front guards at full lock.

I have thoughts of further mods down the track i.e: Calmini upper control arms for extra front travel and a 1" body lift for a bit extra clearance when I get muddies. The suspension is already lifted 2".
It would still be within the Code's 2x2x2 regulation of 150mm total lift.

My tyre placard is non existent, its supposed to be on the drivers door pillar. Was never there when I bought it. Suppose that means I can put whatever tyres on I desire , but seriously the owners manual only states what pressures to run for standard cheesecutters.

Thanks for the tyre info guys, as it was I was outbidded in the last few seconds on ebay for 32x10.5x16 ET's on rims. Almost new too! Bugger!

It was Suncorp Metway sorry

Hehehe ahhhh vicroads!
There is another sort of loophole for us mexicans that I always thought was the case, which is that as the open roads speed limit is 110k's, there is no legal way you can exceed that on the road so that is the maximum required speed rating. Having said that, my understanding is that anything with a DOT E4 rating is good for 140 anyway.

I think you might be being a bit optimistic saying a stock rodeo is on a 31. I would be surprised if they measured over 30.

One way or another, most fo the stuff we do could result in a defect. As an example, Calmini upper arms should be engineered as they are a structural mod. If you certed the arms, then you should be able to cert the car with say an actual 31 10.5 on it at the same time.

No, I said the R9 series (98-03 like mine) LT Sports came out OEM with larger rims and tyres (31x10x16) than the base model LX. No suspension differences either just more extra's. I've seen a few around town. The new regs. state a 50mm larger diameter tyre than the maximum the vehicle came out with is allowable without cert.

I will find out soon if the Calmini arms need to be engineered in SA.
