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.
