Correct tyre pressure: BFG 31X10.5x15?

[Jaco Versfeld]

Hi There,

What is the correct tyre pressure for road use for BFG 31x10.5x15 ATs?

Thanks,
J

More Jaco

ek pomp my 31's tot 2.6 bar op die teer, en sak tot 0.8 bar as ek 'offroad' ry, maar dis mos maar n personlike ding, dit hang mos maar af hoe hard jy wil stamp

Ek pomp my bakkie se bande 2 voor en 2.1 agter en hulle loop gelyk af. Ry ook nie te hard nie.

Jaco, BF's is redelik 'hard' so om hulle so tussen 2.0 - 2.2bar the he sal OK wees

Ek pomp myne 2.2 voor en agter op teer.As ek begin vrag dra gaan ek 'n bietjie harder agter

I prefer to stick to the Toyota recomended pressure. See this thread: viewtopic.php?f=3&t=13253" onclick="window.open(this.href);return false;

Remember that you have an SFA which is a lot lighter then the Vigo shape therefore what works for the guys with that shape does not always work for your SFA. Toyota recomend 1.9 bar for a 215 x 75 x 15 tyre so for a 31" x 10.5" x 15" which is almost the same as a 265 x 75 x 15 you will be slightly lower in pressure. Generally the bigger the tyre the lower the pressure.

gravel road- 2 bar
tar road- 2.2 bar
sand- 0.8-1 bar
rock- 1.4 - bar

Ek gaan op grondpad af na 1.7 voor en 1.8 agter. Dit gee nogal 'n heel gemaklike rit.

Stem saam, heelwat sagter en gemakliker

BFG muds 2.6 highway, 1.1 offroad, rotate front to back every 10000km, wearing even

As Mark said, it's a 'hard' tyre .... this because of the thick 3 ply side walls. IMO 2 bar is more than enough on tar unless you are loaded at the back. I would certainly drop it a little for a longer stretch on gravel, about 1.6 ...... rocky terrain about 1 bar and soft sand 0.8 down to 0.6 if there are no sharp bends or side slopes. They don't be-bead that easily unless there are strong lateral forces.

Dankie! Nou weet ek ook.

foor 2.2 en agter 1.8. werk vir my

Foor is harder om bullbar en winch te dra.
Agter is meestal leeg so 1.8 is al wat nodig is.

Wow, quite a range. I have had recommendations of 1.2 off road, 1.6 on dirt and 1.8 on tar, but the tar pressure seems low. What are the recommendations for best fuel consumption/tyre wear of BFGs on tar with a loaded vehicle (I can survive a hard ride)?

[Mud Dog]

A hard tyre will give better fuel economy because of a lower rolling resistance, but over inflating will cause excessive centre tread wear. As mentioned earlier 2 to 2.2 bar should be fine.
