Hey guys,

since I'm still quite new in the scene, I have a maybe weird question.
I bought my HZJ80 cruiser a few months ago and basically the dealer didn't know too much about it.
Yesterday one tyre burst on the highway and so now I'm thinking about getting at least two new ones for that axle.
However, I'm really confused about what tyre size I can run on my cruiser.
Also I was wondering if it is allowed to run different sizes than the ones written in the door in Australia?

It has standard 31s on at the moment, but how could I check if the cruiser has been lifted in the past and what would be the maximum size without any lifts?

I already figured out, that 285/75/R16 should fit without problems.

Cheers, Mark

Mark,

Yes, 285/75 R16 will fit fine, but if your car doesn't have a turbo on it you would be better off fitting 265/75 R16s these will give you better gearing than the 285s.

I had a 80 series with a 1HZ non turbo motor in it & the 265s were fine, I fitted 285s as a trial & the gearing was too tall.

If it does have a turbo on it then the 285s will be fine.

Forgot to mention, if it has a 2" lift you will have approx. 80 to 100 mm gap between the guards & the top of the tyre.

Cheers, mate.

I did some more research and basically came to the same conclusion about taller tyres and the 1HZ.
"Unfortunately" she doesn't have a turbo fitted.
Quotation marks here, because that's one less thing to worry about and the 1HZ wasn't designed to be equipped with a turbo anyway.
She's not the fastest vehicle I've owned, that's for sure, but as long as she keeps being reliable, that doesn't really matter :-)
I'll probably stick with the stock or 265/75R16 size.
Since I'm going to Cape York this August, I'm thinking about putting some Cooper ST MAXX's on, but damn, they're dear -.-

However, is that clearance/gap with stock tyres?

Doh... brain fade.

I just went & measured the Mrs. 105 series, the gap from the top of the tyre to the bottom of the guard is 160mm on the front & 200mm at the rear, it has an approx. 2" lift & 285/75 R16" tyres on it.

Ya right about the coopers being over priced.

There are plenty of good choices out there that represent better value than the copper.

Maxxis a getting a pretty solid following.

In the all terain market the Perilli scorpion and the Yokohama gelolander tale a lot of beating.

Interesting that Pat Callinhan is on Copper's web site front page saying how wonderfull the coppers are......not long ago he was saying how wonderfull the Scorpions where on his show.

Cooper are throwing tyres and money at any 4wd personality that will take them.

Check the other options...there are plenty.

cheers

if you are in the middle of knowhere an need to buy tyres much better chance of buying standard size tyres for that vehicle .

At the moment 265/75 R16s are the most common tyre out there, this will change as 17" 18" & 19" wheels get more common.

Try & get a 275/70 R16, not very common in the bush but quite a lot of 80 & 100 series came out with them as standard.

I'll second the comment re 265/75/16 being the most commonly available. I did have 285/75/16's fitted for a few years. Destroyed one on the way from Broken Hill to Tibooburra and returned to BH to get a replacement. It took 4 days to have one trucked up from Adelaide. If I had been running 265/75's they could have fitted a replacement on the spot (same brand too, BFG A/T). I've since changed over all tyres to be 265/75.

285 75 r16 aren't legal on an 80 series in case you were wondering. 265 75 are.

Why? Aren't the standard size tyres 275/70 R16?

285/75s are about 15mm larger.

If you are after 2 new tyres then you are locked to the same size as the other two, otherwise the diameters will be wrong and although your model may have a centre diff it will be working far more than it should if the tyres are different sizes.
You should use same size allround. Not advisable to have worn or smaller on one axle and bigger new on the other.

If not a constant 4wd model then you have to have the same, no matter what, otherwise you will get transmission windup and probable damage if and when in 4wd.

It may be a case of 4 new or nothing if a change of size is being considered. Then you need a spare of the same size so 5 all up.

That is appart from the fact that your vehicle will be unroadworthy.

Unless specified by the manufacturer vehicles must carry the same size, type and profile tyres on all wheels.
