Hi All,
In need of new tyres for my Rodeo tray, Qld only allows + 15mm increase in tyre diameter. Whats the overall tyre diameter for a standard tyre size of 205R16? Any opinions on the best possible choices in tyre sizes, whilst still staying legal. I want to get my diffs of the ground as much as legal..
Thanks everybody.
Cheers dornbus

dornbus,

I think that's your sidewall height (????) expressed as a percentage of your tyres width e.g. mine are 205/70R16. 70 is the profile.

dornbus,

It should be written on the side of your tyre. Mine are Road Grippers with a treadwidth of 205, diameter 16 and profile of 70 i.e. 205/70R16. Enter those three figures into Vehicle Stock Tyre Size and hit Compare Tire Sizes. Gives me an OD of 693.16mm.

My Rodeo had 205/75 16 tyres originally but my friend's Hilux has 205R16 and they look taller. I have been told that 205R16 have an 80 profile but that is just what I have heard.

However it is all good and well to try and stay legal but if you are doing this to get your diffs higher off the ground then don't bother as what is 7.5mm more clearance going to do for you?
If your current tyres are still roadworthy then maybe you should wait until Qld decides whether they will endorse the new 50mm increase in diameter.

Have you got a suspension lift? As when I had my Rodeo I used to belly out on things far more often then scraping the rear diff. A 50mm suspension lift would be more beneficial than a 7.5mm tyre lift.

Thanks Utemad,

Any idea when new tyre legislation will be coming in? Currently my insurance company ( budget direct) will not allow any lift.

My advise is change your insurance company mate if they don't allow any lift then you are with the wrong mob. People do lifts for all sorts of reasons, towing, handling, etc etc if they can't understand that then change

my 2 cents

My understanding is that new National Light Vehicle Code of Practice has been passed but Qld has yet to endorse it. So I have no idea when it will be when they will pass or reject it (maybe they will only endorse parts of it?)

As for your insurer I'd be looking for a new one.

Back again,

205R16 i think have 80 profile
if so,
205/80R16 OD 734mm

your options

LT 225/75R16 OD 744mm OR 235/70R16 OD 735mm, which will fit your 16x6 rims

245/70R16 OD 749mm , needs 16x7 rim

I would stick with a LT type of tyre.
Hope this helps mate.

Hi All I run 31x10x 15 on my 96 tray Rodeo and all works good no scraping or fouling, speedo reads about 4% slow but I am aware of this so not a prob. I have better ground clearance [25mm] a 15 in tyre so better side wall flex and 'bagging' when deflated in the sand also a cheaper size of tyre to buy.
Regards Ken.
