Firestone Ride-Rites to the Rescue
We have used Firestone Ride-Rite air bags on our last 3 trucks, The RV dealer recommended Ride-Rite air bags with 60 lbs pressure to mount a slide-in camper on an '01 Ram quad cab. They did as-well-as could be expected with a top heavy slide-in. We have since sold both.
We had Ride-Rite bags on an '08 Sierra and now on a '13 Silverado to tow a 7500 lb GVW cargo trailer. Smooth, level towing at 25-40 lbs in the bags towing and 10 lbs in the bags running empty.Never a problem with the bags, never a problem with springs, and never a problem with being level or swaying.
We have blown 2 tires on the road due to road debris:
A tandem trailer tire came apart coming out of an Interstate construction zone. The trailer was loaded. We heard the tire go and saw the rubber peeling off, but that's it. To our surprise, there was no sway at all.
Road debris penetrated the sidewall on the RR tire of the Siverado with less than 400 miles. We were doing about 70 MPH. The dash indicated RR low tire pressure and we reduced speed until we could pull off. Thinking it needed air, we determined that the tire was totally flat and scrap. Again, the TV and cargo trailer held steady. Fortunately, the rim rode the flat and we didn't damage the rim.
We attribute, in part, the safe outcomes with both of the tire failures to the added stability of the air bags.
