Tyres (yet again)

[Lucy]

The new suspension is in (ome 2 inch lift) on my 95 Disco, now trying to decide what tyres to go with. I have a set of 235/85 R16 Dunlop MT2s which are awsome in the mud, sitting on my currently unused (unregistered cos' it needs work) series 2a shorty. Do I use them or do I get some decent ones in normal size. This car is a work car, and my staff use it, so it has to be legal - OH&S as well as insurance etc.

Who has bigger tyres, and have they been engineered? If so, if in NSW who issued the engineers certificate?

Thanks in advance.

Unless you're using it for mud during work hours doesn't seem much point going the big tyre and wasting them on work driving, plus the extra cost and the extra road noise.

You've already got the MT2s for weekends.

I would suggest the following:

Option 1: Save yourself time and money and get a good set of AT's, or if you prefer MT's in a slightly bigger profile. If you don't exceed the rolling diameter of the standard tyre size by 15mm they are considered legal without the need for an engineers certificate. Have a look at an online tyre calculator to see what your options are.

Option 2: Fit a set of cheap standard sized road tyres to be used by yourself and employees during the week, swap them for the muddies on the Series 2 over weekends when you go out to play ... (When OHS is not an issue)

Cheers,
Henry

Forgot to Mention: Work is often offroad in hard to get to places, muddy paddocks, National parks (behind locked gates style_emoticons/<#EMO_DIR#>/biggrin.gif ) etc. And I really couldn't be stuffed changing tyres when I want to go play, it means planning ahead, and when the opportunity comes, I just need to go, not spend 20 minutes changing tyres.

I either stick with standard, or get it engineered, I am just trying to find someone/anyone who has actually engineered the change, and where they had it done, and how much. If the cost of the change approaches even half the cost of a new set of tyres, then I'll just go the tyres (and maybe sell the MT2s)

Tyres are also deductible as a business expense, but the engineers certificate etc would not be. 8)

In that case I'd suggest Option 1 above. From memory an engineers certificate is not cheap.

The Poll is surprising!

I used Duan Phillips from Garden Suburbs near Cardiff, near Newcastle to engineer my truck. The cert cost about $300 or something.

Larger tyres ie > 15mm larger than standard dia, even with an engineers cert, will it hold up in case of an accident or will insurace companies still try to back out of the claim? Any experiences here?

I'm guessing mine was engineered as the dealer had to get an engineering certificate for all the mods on my rig when I bought it. It's running 285 75 R16 Muds.

RTA are really clamping down on bigger tyres that are not engineered.

I got mine engineered for 35"s when I rebuilt the car earlier this year.

You have to let them know about the tyres and other mods. DGA have been fine with me.

My tires are what my Insurance allows

7" rims

any Diameter, So i have 265/75/16 on Dico rims for normal use and 32" Simex ET's for serious playing....

Any mods i do my Insurance company knows about.

[LRHybrid100]

My Insurance company, AAMI, says they will accept and insure any of the mods as long as they have been engineered and approved with RTA.

No 100% when it comes to claims though 8O
