BFGoodrich All-Terrain T/A 235/85 R16 tyre pressures
As most of you know, BFGoodrich is owned by Michelin. Until now Michelin UK have not been able to obtain any off road tyre pressure information from the BFGoodrich people in the US. This has now changed and I have just got the official off road tyre pressures for the BFGoodrich "All-Terrain T/A ko LT235/85 R 16 120Q" tyre.

For track/sand, at a maximum speed of 40 mph, tyre pressures can be reduced as follows for these axle weights:

1100 kilos: - 19 psi - 1.3 bar.
1200 kilos: - 23 psi - 1.6 bar.
1300 kilos: - 26 psi - 1.8 bar.
1400 kilos: - 31 psi - 2.1 bar.
1500 kilos: - 33 psi - 2.3 bar.
1600 kilos: - 38 psi - 2.6 bar.
1700 kilos: - 41 psi - 2.8 bar.
1800 kilos: - 44 psi - 3.0 bar.

Because of the stiffer sidewall construction of this tyre, they do not recommend the same order of deflation as can be used on Michelin tyres, such as the "4x4-O/R 235/85 R 16 120Q", which can go a lot lower at the slower speed of 12mph.

If anyone wants a copy of the official Michelin spreadsheet of tyre pressures for track (40mph) and sand (12mph) for Michelin tyres send me an email.

What's the correct pressure to use on normal road use ?

Cheers
Matt

The pressure on road varies with the load , as it does off road above post .
the rule of thumb is look for a rise in pressure of 4psi
The op is as follows set tyre pressure cold , then after a run of say twenty miles when tyre is up to normal operating temp , take pressure again (use the same guage) If pressure is up 6 psi then start pressure cold was 2 psi too low . If it is only up 1 psi then start pressure was 3 psi too high . This is optimum , but manufacturers tend to go for too hard to start with as its less likely to damage tyre if run with load an too soft . HTSH

Thanks for the feed back on the tyres... I've just bought a set from camskill at £125 each which is the cheapest I've found on the net...

Kindest regards
Matthew

IMHO Get the best online cost at Camskill and then phone Paddock Spares who will beat or match it.

I do this due to having issues with camskill delivery and customer service in the past.

If anyone's after one brand new (fitted to a rim, but never driven on) BFG AT 235/85 16, give me a shout.

Happy travels
Sam

3000kg is too much per tire for a single BFG. Better look at an axle of 3000kg with a robust tire like 235/85R16; if you need 3000 kg on a single tire better look at something in the upper 19.5 range or 20" tire.
