You will need to
check your state regs and
check with your insurance company, also under body clearance,
suspension etc will be an issue; your low range will also suffer as will the engine power, steering, stability, braking performance and fuel economy.

9% is a huge difference in gearing - it will feel like a slug.
But the extra footprint, clearance and diameter will improve it offroad.
BTW, there's plenty of "10 ply rating" tyres with thin sidewalls. Its got nothing to do with plies (used to mean 10 cotton plies in the old days).

G'day Nick
I have on my Jackaroo a similar size tyre difference as you are considering.
Recommended is 235/60/16, I have 265/75/16.
Yep, the speedo is out about 9%, but I don't feel it is a slug. I guess I know no different, as this was the size tyre on the car when I bought it. I replaced the tyres with that same size when they were required, as I was happy with them.
I didn't know about the laws regarding tyre sizes until I started coming on here, but ignorance is no excuse in the eyes of the law.
Funnily enough, my son in law who also has a diesel Jack, loves driving my car, says it is so much smoother than his. I have never mentioned the tyres to him (he is a Highway Patrol Officer!).
I have a
suspension lift, I don't think the tyres would fit otherwise.
Cheers and good luck on your selection, Dave

Standard size Dave on Jacks is 245/70/16, son had 265/75 on his petrol Jack but has since gone back to 245/75 which are legal. But the big tyres certainly help in ruts.

G'day Pete
My sticker says 235/70 or 245/70.
Either way, my 265/75 are too big, according to the rules. Again, my 265/75 help me in ground clearance (as you
well know), so I prefer to be 'ignorant'.
Hope to meet you some time, Dave

Hello Nick,
If you are running the standard 6" rims I would not run any larger than a 215/85/16. With 7" rims a 245/75/16 would be the best size. Both these tyre sizes have the same outside diameter by memory this was about 775mm.
I ran 235/85/16 for a while on my Triton and found some of the disadvantages were that it geared it up to much, fuel consumption increased, greater dependence on breaks on steep long descents (
mine is an auto) and sluggish performance in over drive often requiring me to switch it off.
The above tyre sizes will put the speedo almost spot on with actual speed at 98 while speedo reading 100.
Cheers
Tony

Just as a follow up . I have changed tyres to 762 bighorns 235-85-16 fit on std rims 6" recommended rim size 5.5 to 7. they should stand 805/808 high but these stand 790 with no weight on them 78*on the vehicle .that's max legal in SA for a 4wd .
speedo read 100kh - gps reads 101/102 . with the std 205 the speedo must have read
well under 95 !!!
the tyre are not that noisy on this ute . it is noticeable difference in gearing , doznt pull up steep hills like before ( with std 205 tyre it was quite quick )
vehicle handles better turns in to corner quicker ,a lot less wheel spin on gravel roads as the std 205 were very snappy on the loose gravel rds .as long as it doznt use a lot more i'll be happy with the change .
regards nick

Hi Nick,
I hope you are happy with your choice of tyres. For a while including one desert trip I ran 235/85/16 Goodyear MTRs. These were excellent tyres but rate of wear was high. This tyre size, while being excellent in
the desert geared it up to much for steep high country trips.
Its ridiculous how far out the speedo is with the Tritons. Not only is the speed reading out but so is the distance. If you work out the fuel consumption going on the trip meter with standard size tyres it works out much better than what it actually is. For every 100k you travel you will have actually only gone about 94k.
Cheers
Tony
