When asking question like this it would be best to give all the details of the tire. I am assuming (and we know what can happen from that) that you have this tire: http://www.tirerack.com/tires/tires.jsp?tireMake=BFGoodrich&tireModel=All-Te rrain+T%2FA+KO&partnum=17R6ATAKORWLV3&vehicleSearch=false&fromCompare1=yes This is a lot of tire for that vehicle. However, due to the heavy duty construction you need to pay careful attention to tire inflation as sidewall heating will be this tires weakness. The right thing to do is weight your van (each axle) and then get the tire load-inflation table from the manufacture. That will give you the minimums. The attached file (if you get it) has the load inflation tables in it. Go to page B23. Note the minimum inflation pressure for that tire design is 35 psi and at that pressure you still don't have capacity for the axle load. Then you can adjust for handling afterwards. From experience this tire works well at 40-42 front and 46-50 rear. At 29 psi you will damage those tires in short order at highway speeds. Keep in mind that while this tire seems to work better on road than the tread pattern appearance would lead one to believe this is not a handling or high speed performance tire. The high void ratio while great for clearing deep snow or mud and preventing hydroplaning also leaves less rubber on the road for actual grip. The non-rib tread also takes away from directional stability. Increasing the caster angle will help make the van want to travel straight. Be sure to rotate frequently. Up front the outer edges will wear choppy and make the tires very noisy. The noise will sound like bad wheel bearings. Let me know if you have any further questions. If anyone wants a copy of this tire manual let me know and I'll forward it. Dennis

Took them to get rotated and they look really low now after the fact.. Just checked. They're 29-35 psi right now. Seems way low. Well looks low anyways. Thanks a ton guys.. Abel. |
