TYRES ON MY JACKAROO

Mark....I don't know of anyone that is doing 265/75's locally, but I do know of Isuzu Trooper owners in the USA running 275/70R16 Pirelli Scorpion AT with a little rubbing, and 265/70R16 BFG's without problem. I think 265/75R16 might be pushing the envelope a bit too far. The largest I would go is a 265/70 or 245/75. Just keep in mind that a 245/75R16 gives you a similar same height increase as a 265/70 without any width problems. Before you do any of that, check with your state's authority for vehicle regos on the legality of going to a size like that and also check with your insurer. In NSW, the RTA guidelines say the maximum you can increase width is 20mm over standard and height by 15mm over standard. This actually limits you to a 255/70R16. The NRMA stated to me that going to a 265/70 is ok, but then said that anything that renders the vehicle illegal will void the insurance. Go figure!I have a Monterey with BFG's in std size 245/70R16 and would love to go to 265/70R16s.

Mark, as Savvas said, you may have some insurance worries by going to that size.
I am running 245/75/16's & i think they may even be technically illegal.
I certainly think that 265/75's would probably rub the guards.

I have looked at getting BFG ATs and I found that the 265/75 were going to void my insurance, the 245/70 ora size between the two mention were ok but that "mid size" (I think it was 255/75) was going to be $300 instead of $245 and $265.
A big price for a little differance.

G'day Mark, why do you want or need to go wider? Getting more clearance I can understand, to a point, but wider? We are assuming the BFG's are A/T's. A reasonably aggressive tread pattern. So, if you go wider the chances of aquaplaning are higher. No advantage. More danger?! Sand? The aggressive-ish tread pattern of the BFG A/T in sand will make your Jack work harder. More chances to get bogged. Wider has to move more sand. A bald tyre is the best sand tyre, assuming tyre pressures are equal. Ignoring the probable debate on which is better in sand, wide or narrow, go with a 245/75. Mud? I prefer to cut through the goo and find some traction. And I would be using a muddie tyre, if thats what I planned on doing most.Rock-hopping? I know little of, but I guess this is where I would like the extra width for the extra rubber surface area to grip on to the rocks. Or, are you just looking for "sexy"? We run the 245/70's on our Jack, but will be going to the 245/75 to get that little bit more clearance and get the tyre type we want thats not available in the 70. It also seems that the skinnier tyres get less sidewall damage than the wider ones in outback driving. Most residents of the bush go for the narrower tyres. Ultimately, the choice is yours and the reasons your own, and we are just giving you our views of the way we see things, right or wrong, so as long as you are happy with the choice you make, thats all that matters. Good luck:~)
