g day folks.
i'm finally going to replace the dunlops on my 120 prado.
most likely will go for the cooper atr. my question is should i go for the light truck construction, only available as 265/70/17, or passenger construction, which you can get in the original size 265/65/17.
is the LT design significantly more puncture resistant? will the increased diameter not only put the speedo out (how much?) but also the odometer and auto transmission? basically what i'm asking is, is the extra strength of the LT worth it?
thankyou all tyre gurus, and anyone else with an opinion/experience!

The LT will be more puncture resistant but not (normally) as quiet as a passenger spec tyre. Generally not a "pleasant" (roadhandling/noise/comfort) on the bitumen, but far better off the bitumen (stronger construction/heavier sidewalls/deeper tread/higher load rating/longer lasting).
Throwing the question back to you, it depends on what/where you can see the
miles being travelled. >90% bitumen/city driving, probably not worth going to LT. Any harsh road terrain (gibber,
forrest, etc) wouldn't be without LT construction.
The difference in diameter is nothing to be worried about 31.1" vs 31.6" nominally, or about 1.5% (speedo reading 100km/h, doing 101.5km/h)

Gday Jon,
First of all i am not a tyre guru, but i just went through this same exercise myself with the same vehicle. The difference in the Cooper Passenger and LT construction prices was an extra $35 dollars per tyre. For that you get a few speedo and odometer issues but you also get extra tread depth and an increase in load carrying ability. If looked after, you should get the extra kilometers out of the LT construction tyres to make the extra cost irrelevant.
I spoke to my local Toyota dealer about any transmision issues and they said as long as all 4 tyres were the same size there would be no issues. I personally have not noticed any difference with
mine as far as acceleration or performance goes.
As far as the LT being more puncture resistant than passenger tyres, my answer based on experience with different tyres is a definate Yes, but it is also dependent on who is driving the vehicle.
Because i went up in size i had to get 5 tyres to make the spare the same. I was also interested in the Cooper but instead based on recommendations from others, i went with Trailcutters in a 265/70R17 LT and saved myself $500 over the equivalent Coopers.
If you do happen to go up in size, make sure the spare is spaced so that it does not rub the paint off your door.
Good Luck.
Cheers
Dave

Dave, easiest/cheapest way for spacers is 3 x 1/2" spring washers on each spare stud from Supercheap. Worked for me. Others have inserted spacers behind the spare mount frame but I'm not sure what that'll do for the bolts mounting the frame to the door.

Jon,
Go to www.jetzontire.com and look under look under catalogs for Trailcutter A/T.
Thought i would give them a go due to the unavailability of BFG's and the price of the Coopers. A couple of guys i know use them and have been very happy with them. One set has 45000 ks on them and still look good. Another bloke has just gone on to his second set. As i have said below, i originally wanted BFG's again because i could get them for $65 a tyre less than the Cooper and i know they are capable of high k's.
Because there is a 27mm difference in overall diameter from a 65 series to a 70 series, the tyre if not spaced away from the back door will rub paint off. Like AJ from above, i used 3 thick flat galvanised washers on each stud. I wrapped the 3 washers tightly together in electrical tape to keep them together when the spare is removed. You cannot even see it unless you know what you are looking for. Works
well.
Cheers.

Hi Guys,
I'll throw another one in the pot BFG 265/70/17. ATR's. Been on for 12 months now, no complaints whatso ever. Issues referred to in post, Spedo is Plus 6 percent, therefore odometer will under read. So you have to watch that one with all the speed cameras about. Also these ATR's lifted the vehicle 14 mm at the trowbar, a welcome increase in clearance. Coopers were copping a lot of flack in
forum 12 months ago, thats why I went for BFG's and they have been great... been to Kimberleys and desert. On a completely unrelated matter, for about $300 odd try fitting airbags to the rear
suspension... you get about a $3000 improvement... they are brilliant.
good luck.

Yeah i tried to get the BFG's but i could not get any from any dealers until mid October. As always i left it too late and needed new tyres immediately. I have had them before too and was not disappointed.
Cheers
Dave.

New 120 series Prados have a piece of black sheeting/plastic that sits between the spare & the paintwork. This was a problem highlighted on and was discussed on the LCOOL website. Don't know for sure if the plastic is big enough for a 70 profile tyre, perhaps Mr Toyo could tell you and sell you one if you want to go down that track. They might even give you one under warranty as a known fault. Just have a quick peek behind the spare of a brand new Prado & judge for yourself.

The plastic shroud has to come off with 265/70/17s, they are too big to fit it. Also the full hard covers are too small for 70 AT's. With the spacers in I run a bushranger soft cover. There's enough room to fit it under the rear wiper and get the tie elastic in behind the tyre case to knot off.
