265/70/16 BFG A/Ts tyre pressure

40 on road
8-9 in sand
15 "Rock craling" etc

8-9 in sand seems really low. Are you using internal beadlocks ?

38-40 on road 18-25 off road. My BFG AT's just gave me 80K I gave them hell

Wow that's great mileage! I'm hopefully picking up my new Triton soon and would be wrapped in that. My partner has a Captiva and it chews through tyres on her unbelievably.

The “hot” tyre pressure should be 4psi higher than the cold tyre pressure. For example, if I if run my tyre pressures at 35psi (measured when the tyres are cold) and measure the pressures again after an hour or so on the road, they should be at 39psi: that is 4psi difference between the cold and hot pressure.

If the hot tyre pressure is more than 4psi higher than the cold pressure, then start (cold) pressure was too low: if the hot tyre pressure is less than 4psi higher than the cold pressure, then the start pressure is too high…

my Mickey T MTZ (mud terrains) on a highway run 100+ klm/hr were cold at 42psi and went to 46+.

i was surprised as i thought 42psi was on the hard side of normal. So if the 4PSI rule applies 42 is about your pressure for these tyres at highway speeds.

A quick question for guys running the 265/75/R16's how do you find the effect of these tyres on handling?
Has its decreased the initial take off speed slightly as well?
And what is the effect on low range gearing?
I was also concerned that it would soften up the ride having a bigger side wall (my assumption more compression) but from above i see this might not be the case?
Thanks

Hay Saltydawg, yeah you will notice a bit of difference with them tyres. Depends on what diff ratios you have... Most of the MN's run 3.9's and handle them fine. Mine is a GLX that came with 3.6 ratios which was no good at that size with any sort of load on the back... Had to swap them down a size to 245/75/16 to make it more drivable.

G'day guys,

I have an MN GLR with the stock alloys and are shortly going to purchase some BFG ATs (TA KO). Will the 265/70/16 fit without rubbing or issues when you only have stock suspension?

I do plan on getting a 2" Ultimate lift shortly but have some renovations to pay for at present. It would be great to go up a size from the standard 245/70/16.

Thanks in advance

[Cowboy Dave]

they'll fit

[stackator]

Thanks Cowboy Dave, the guy at Jax Tyres wasn't sure if getting a wider tyre without a lift would rub on the inside of the guards or brake calipers and recommended that i get standard width being 245/70/16

[Cowboy Dave]

Tyres won't hit calipers anyway. Non standard rims might but not tyres.

Hey mate, I've purchased these tyres just a month ago. And ive found on road no problems turning. Yet once i get off road and im in lock or close to it, With ruts and rocks etc, they DO scrubb for me. I have stock suspension. Hopefully once i get my Ultimate Susp- They will fix my problem! Food for thought

Thanks mate greatly appreciated, I might go standard size until I get the lift. On the upside the standard size is close to $100 cheaper a corner too which means I can get the lift sooner from Ultimate

Good to hear mate All the best!

You can work it out from the Tyre and Rim Association load inflation tables. Using the tyre placard recommended pressure, find the load per tire for the standard fitted tyre. Use the load per tire figure in the TRA tables for LT265/70R16 to look up the required pressure.
You can do this again for the max/trailer towing pressure.
e.g. for MN P245/65R17 @29psi as per the placard, the load per tire is 1885 lbs, looking up the tables for say LT245/70R17, the load per tire which is equal to or above 1885 lbs is 2010 lbs which requires an inflation pressure of 45psi. You can get this more accurate by plotting the tables, it is a straight line graph and by working out the equation for the line, you get 41psi for LT245/70R17 is equivalent to the specified 29psi for the original P245/65R17.

Interesting information, freeball. Thanks & welcome to the forum. I see you've been a member for nearly a year and this was your first post.

I had a look at the TRA site and you do need to purchase the documents containing these tables.

Some tyre manufacturers do, however publish data relating to their tyres and this might be useful for those who wish to do the calculation.

The tables for Toyo are available via the link in the centre of the following page:

http://toyotires.com/tires-101/load-and-inflation-tables

Other manufacturers also have them.

Thanks Freeball, that is a good tip I will be sure to take a look.

I think that I have met your relative 'Teabag'

I have the 265/75/16 Cooper St maxx on a MN single cab tray and they were fine even with standard suspension. The MN is over geared for me even with standard tyres so the bigger tyres dont make things easier. Triton really needs a six speed box with first being at around 5:1 at least.

For pressures I run 42psi and go to 60psi for full loads when i remember. Lower than 40psi I always run into uneven wear problems.
