285 75 R16 vs 265 75 R16

Thanks all for the answers. Still deciding between the Open country in 285 or the Wildpeaks in 265. The Wildpeaks in 285 will be way too heavy, this is going to mess up my fuel economy for sure. Also Im on 13-14L/100km right now with my 1fz (not sure how) which is really nice, dont want to reach the 17 mark by putting much heavier tyre.

A mate told me he fell his 80 becoming (even more) sluggish after going from 265 to 285, but it seems like not everyone felt that.
 
I just don't know if I need the extra clearance (3cm...) that 285 bring. If that cost me an extra $400 per year to run, probably not. Someone said 285 could make the fuel economy better but I've been reading the opposite as well.

Edit: something that I realised that could make me decide sooner than later. Would a 285 75 R16 fit as spare underneath (chain system). If not, then it's an easy choice.

285 will give approx 1.3 cm height increase, remember its overall diameter is 33" compared to 31.8" and only half that is touching the ground

fuel economy wise, what ive observed with mine running 285's is pretty much the same as what youre getting. I did a recent trip up the high country with the car fully packed & towing a trailer with 2xMTB's, a DirtBike and 20lt Fuel can and it came out to 14.8L / 100km.
Unladen it's 13-14 lt/100km consistently but the right foot and tyre pressure's have a lot to do with it as well.

Nice thanks mate. Right ofc, 3cm divided by 2, makes sense. Does the 285 fit as spare underneath? I dont have a tyre rack at the back, way too $$ haha.

your mate isn't lying.. the car definitely felt a bit peppier on the factory sized tyres, but the difference isn't massive and the 285's do look a lot better, which is why I opted to stick with them after much back and forth. If you were in Sydney, I'd take you for a spin in mine with the Yokos. I dont think you can go wrong with the Toyos.

i think that mod only works with cable driven speedometers

I installed the gear: 33403-69225 in my US spec 1997 FZJ80 with a 1FZFE and A343 transmission. In the US I think all speedometers went to sensor/wire with the shift to the FZJ80 and away from the earlier FJ80 though I'm not totally sure on that. Here's a post for some reference:

Thread 'speedometer system on the 80?'

OK, I'll admit it, I'm too busy (OK, lazy :)) to try and figure it out myself, but it's been on my mind so I'll ask since you guys are so good technically and reasonably forgiving :D...


Now, IIRC, there is a cable coming out of the trans (or is it TC) for speed info. I assume it's a mechanical cable from what I remember of it (thick, O ring at the case for oil etc). Yet, it seems like the speedo is electronically controlled from what I remember reading here (may be wrong).

So, if it is an electronic speedo (is it?) and if it's a mechanical cable (is it?), what's with that...

Near the end of the thread ToolsRUs says he thinks the gear works for both cable and sensor setups, which makes me believe that's likely true. Not sure if the gear will work in your 80 or not but it's worth looking into as an inexpensive, simple and solid way to keep your speedometer accurate with 285s without adding more points of failure, complexity. I think I paid around $25 for the part and I've confirmed my speedo readings with gps across a range of speeds and it's very accurate.

haha thanks mate that would be nice. Thing is size of tire can only be compared in one individual truck, drive feel depends too much on suspension / lift situation, overall load, engine condition etc. I would love to just put 285 on my truck and have a feel then switch to new 265 and compare. No other way. Unfortunately thats not possible

oh,ok, interesting.

i looked up the part # and saw this where they say its for cable driven only. If it does work then would be handy as down here they get you for a couple of Km's over yet let those that break into houses off scott free........

yep, I was in the same boat.. wishing I could put factory sized tyres back on just to test drive it. The other thing that made my mind up to stick with 285, was their availability. The factory sized tires in Australia are surprisingly difficult to find and generally not as readily available. I'm sure you'll be happy either way you go.

Your talking about a tyre that's 15mm taller
3-4% larger circumference IF the tires are true to size. Really splitting hairs.

Your revs at 100km/hr would drop by 3-4%, so cruising, you may use less fuel. Bigger tires are known as a rubber overdrive because of this.

The other side of that is, you'll have 3-4% less torque at the tires, so when you hit a hill, it will want to down shift slightly earlier so you may find is dropping to a list gear more often.
It will also have to work 3-4% harder to puli away from red lights which can feel like it's more sluggish.

You're right I'm most likely overthinking it. Btw 265 75 R16 is not factory, factory is 275 70 R16. This is the spare I have underneath + what is written on the door. 265 is slightly taller and thinner.
 
and I'm not sure why the PO did not buy 5 tires , having a spare a different size underneath is the best way to overheat your diff, I got a flat tire in the middle of nowhere the other day and it was painful.

Ah yep, that's right, and the 265/70R16s were easier to get a hold of, as I was also considering them too. @mudgudgeon has given the best stats so far.

Vast majority of new cars come with a tiny space saver spare.
Recommended for max 80km/hr, and 80km distance. Enough to get you to a tire shop.
I've had and used mismatched spares since forever, a small difference is nothing to sweat about IMHO
 
On a side note, does anyone know which model 80 series came with these rims from factory? I can't seem to find a single set for sale in Australia!
I did see them on what looked like a VX import the other week, but that's about it.
Our Sahara's came with different rims again.

Any insights would be great. Thanks!

there was a set of 5 of those with 33" maxxis mud tyres for sale not too long ago on FB Mktplc
im still kicking myself for not getting them as they were going for $2000. Pics of the tyres showed they had bugger all wear on them too.......

I think they came on the Sahara's and also remember seeing them on the 'Blue Marlin' edition 80 series that was out just before the 40th anniversay. They were also an optional extra when I bought my 80 new

Those were the standard wheels for North America 80 series Cruiser and JDM
That's a really nice set

damn! that would have been a good buy! I'll keep looking.. maybe a set will come up. I don't mind my current 'Auscar' rims (which oddly enough, some toyota dealerships in Aust offered to customers, even though they arent genuine Toyota rims!).. but I think those factory ones would look a bit nicer.. thoughts?

Current 'Auscar' wheels, that Newcastle Toyota offered as an 'upgrade' when my folks bought the car back in 1994. I have only seen a small handful of other 80 series with these rims before.

I dont know which trims of the 80 series got those in Australia, that wheel is basically the only one we got in the US, but I do know there were two versions of that wheel pictured and they used different lug nuts. So if you find a set, make sure you get the right lug nuts. I think your current nuts will fit the early version, but the late version used a different type.
