cooper sst 285/75 16

i used cooper mt's for three years travelling around west qld without getting a flatty..then i was talked into buying bf goodrich at's..too soft for out here.so i will go back to coopers but just trying to decide which one's..any cooper user's out there..

Hi Mark,
When you fitted the Coopers did you do any other changes to compesate for the size of the tyres, ie low range, speedo, up hill and hill starts etc.

My speedo was way optimistic. After changing to the 285's, the speedo now reads 100km/hr at a real 101km/hr (Garmin V GPS). Thats about as accurate as you could ask for.

As for the gearing change, its "only" 7% different and I reckon that the higher gearing on-road is good, except when taking off uphill with a load (I have a 1.6T off-road van). Low range is too high for my liking anyway, compared to my old 80 series cruiser, but I don't reckon the tyre change made a noticeable difference.

Overall, I MUCH prefer the significantly better off-road performance of the larger tyre size for the minor sacrafice of gearing change. Increased on-road gearing is an advantage IMHO, except as mentioned earlier. I am very glad I made the change to 285's.

Hi Mark thanks for that i have a patrol TI and am thinking of fittin the same tyres at the moment have BFG 275/70/R16 A/T are your tyres legal as some place up here in Qld they say they will not fit them, also what size tyre did you truck come mine were the Bridgestone 275/70/R16.

Mine originally came with 265/70 Bridgestones (31") but I changed them on the way home from the dealer. Cost me $600 for 5 brand new tyres, reckon it was a good price for changeover (but the missus reckons I just got new tyres already!!!)

The tyre dealer (Tyrepower) reckoned there was no problem, I specifically asked them as my 3.0TD GU came with ABS. He reckoned that 31" to 33" was legal as the model also came out with 275/70 (32") thus it was only 1" (25mm) increase on max available tyre size (apparently also came with 275/75 on certain models).

To my way of thinking, IF anything ever came of it insurance wise, I would handball it to Tyrepower. But as mentioned in other posts, there is a whole lot of talk about the legality of tyre sizes, but who has actually had a REAL problem with insurance because of it. I am not talking super size tyres, just a 285 that looks like the Patrol guards were made for. Too much govt red tape on minor issues IMHO.

Anyways, I am happy with the 285's and happy with my ignorance of legal issues.

Cheers

My Wife should met with yours i did the same with the tyres, Bull Bar, front diff rear diff fuel tank rear bar side steps and the rest before it got home " what are you doing with it she said its in bits and we have not had a ride in yet" they just don't ubderstand mate but just want it to get them home.
I have tested my speedo with the gps and it reads true so is there a difference to the 3.0 and the TI or maybe its as you say all Patrol should have been fitted with 285/75 to start with. Anyway thanks for all that think i will make the change when the Patrol gets back to Aussie.
Great to be able to speak to someone whao has experienced the same thing with same vechile.
Good driving
