BFG: Tyre Pressures

Duppie · Mon Jul 25, 2011 8:57 am

Hi Guys,

Just fitted my first set of BFG's.

What is the correct pressures to run BFG's 265/65/17 in the following conditions:

- Daily commute - 2bar?
- Sand - 1bar?
- Rocks - 1.5bar?

I got them at 2.5bar currently it seems to me too high. Also road noise is much higher than expected.

I have 16" on my pajero and run them 200kpa at all times - my driveway is 4km of dirt road.

If I plan to drive long distance I bump the pressures up to 230kpa.

If I plan to go offroad I drop them to 130-150kpa.

How about metric

We live in a metric country ... and if you can pump up tyres to go offroad to 9 bar, be my guest

While pressure vary according to vehicle and wheel sizes, I used to run my BFG's at 1.8bar for general commuting, 2.2 for highway when loaded, 1.3 for offroad and 0.8 for sand

If you are serious about finding the correct pressures, the "4 PSI" rule is the closests you will get to the correct answer.

(Google / search "4PSI rule")

ok ok ok. My mistake.

I usually just look at the numbers, not the denominations. hehe
