Hilux Tyre OEM Info

[curious_george]

I was hoping for a little help please.

Where would I find some information about the original tyre size for a 1992 Hilux 4x4 Double Cab? Or, better still, some info on the largest tyres I would be able to fit without getting a cert? It's a jap import.

I have been given a set of 245/75R16's that I've fitted on, and seem good. They replaced a set of 235/75R15's that were on it when I brought it, but I have no idea if they are original or not. The spare that was on there just has 215 R15 on it but again, I don't know if it's original.

Using a GPS, the speedo actually seems to be a lot more accurate with the new tyres than with the 15's I took off so I would think that would be better than the old tyres.

I had a look on the LTNZ website but couldn't find anything, so rang them today - with no luck. I was flat-out told that they don't keep a register of tyre sizes - which kinda makes me wonder how they can enforce the whole 5% thing if they don't actually know what is was originally! How do they do it?

Any info would be greatly appreciated please.

33"s seem to be a good size.... what motor is pushing them?

Just a NA 2.8L diesel.

I'd prefer to be able to drive it on the road also so a great big set of feet would make trips take forever!

My mates 95 single cab (cab/chassis) hilux came new from toyota with 700x15 SATs on it which would make that model come out with 28" tyres

fairly sure that 215R15 would be factory size

open the drivers door and look down the bottom of the B pillar below the door latch somewhere and there should be a sticker with the factory tyre size and recommended tyre pressures.

Hmmm I wish it was that easy! It appears that sticker is long gone...I think my best bet would be to find a truck the same and see if that has got it's sticker perhaps?

99% sure that 215 R15 is factory

235/75R15 is roughly the same rolling diameter

lots of folks go to 33s without too much hassle

I work in a tyre shop and use that site on a regular basis (very handy)

Ah ok. With that in mind, and throwing it into this other site I found which is pretty good:

I get two different rolling diameters with a percentage difference of 5.51% - not cool really I guess that means I need a cert if I want to keep them on there on the road?
