I run my 265/75/16 Pirelli Scorpions at 40psi front & rear as reccomended by the tyre store. This is fine for the highway and at the beach I deflate them to 16psi which is fine also, my problem is when I hit the dirt tracks here in West Oz especially the corrugations, 40psi is just to hard and bounces the disco all over the place. Can anyone suggest what psi I can drop these tyres to for these tracks and still expect reasonable tyre wear, or is this going to be trial and error? |

Well the stock tire pressure recomendation is 26 frt, 36 rr. You having bigger tires with more volume of air, should run less than that. How much less depends on the load rating of the tires. 245s are typically rated for quite a bit more load than 235s. I'd say try 24 frt and 34 rr and see how it drives. |

Let me know how it turns out. You can also draw a chalk line across the tire to see if you're running over or under-inflated. |

to elaborate on what Milan mentioned: you put a chalk line across the tread and drive straight for a few revolutions of the tire. the chalk should wear evenly with the correct pressure. more chalk worn in the center means too much air. chalk worn near the shoulders mean too little air. Jaime
