Tyre choice

oh....and are there any insurance issues having a slightly bigger tyre?

Prospect - check with your insurer BEFORE you fit the new tyres. Can't hurt & will only sting you a phone call.

I've got Cooper ST's and they've done nearly 70000Km's just fine. I run the 225/75R16's on my Prado RV TD. Am thinking of going to the same size tyre as you in another 30000Km's or so (yes - the Coopers will make 100,000Km's for me no worries!). Just be careful EXACTLY which Cooper ST you get fitted at that size as I believe there are 3 different ones - each with slightly different load ratings avaialble at that size. Be careful which one your supplier orders for you.

Also - all the 265/75R16's are speed rated N from memory - means 140Km/h max.

Cheers,
Prado Boy

G'day, prospect,
Tyres and choice of tyres has become subjective throughout the 4WD community and really it's your choice whether it's the right one or not. I can only offer my personal observations in the tyres I use ( Hankook MT Radials) on my GQ LWB. I've previously used them on another 4x4 and found excelent wear 65,000, admittedly these were on a '82' Jackaroo but I'd been to the Cape, all around NSW, Victorian High Country(lived up there for 3 years), around WA for a year. I found this brand of tyre to be useful in all types of conditions and only bad in one application(sand) but if you let them down to 10psi no problem
Best of luck with your decision, don't get sucked in and pay to much

I had 265/75/16 CooperA/T's fitted yesterday to my GU.

1st thing I noticed was how quiet they are. Other than that, it's too early to tell.

I asked my insurance Co about the tyre size change. I was told I can go taller but not wider. I told them exactly what tyre I wanted, they said OK and noted it on my policy.

Check with your mob. Different companies, different story.

Coopers are good, i use them and really happy. I use a gps as speedo in my ute as it about 18% out, so check yr soeedo with a gps.
If travelling out bush always consider the availability of tyres in remote stores. The new ST is not a bad compromise between sealed and dirt road

Prospect, what is the largest wheel/tyre combo stated on the Prado's tyre placard?Smile, you're on ExplorOz

You can safely, and legally run up to a 285 on a Prado (in Vic & NSW)

You will need to get an engineers cert. ($3-400) and this will cover you for insurance etc.

Hey there, my mates and I run cooper S/T. I have a challeger and both of there's are patrols. These tyres are perfect for both on and off road conditions. My mates have managed to get 70,000 - 80,000km easily out of theres. They are also pretty quiet on the road, not like many other A/T tyres. But once again it's a personal choice, but I would highly recommend cooper S/T's or for heavy off road work all the time, Cooper STT.

Thanks for all your advice...I'm now a bit worried as I ordered 5 new coopers 265/75/16s today...I was told by my insurance company that I could go up to an inch higher without any problems. I was told by the tyre company that going from 70 to 75 would mean an increase in height of 20 mm (under the inch). So I thought no problems until I started to read about the load index and speed ratings. Originally the LI on the Prado is 112 and SR is S (180km)...with the coopers this changes to a LI of 123 but a SR of N (140km)..now my question is does this matter? I think a quick check to my insurer on Monday is needed...but I'm assured by the tyre company that it wont be a problem, and that given taller tyres are being fitted, with a higher load index, it was all ok... Any thoughts? I'm in SA.
