Tire pressure when trailering a dragster

Postby JDteam » Wed May 02, 2012 8:50 pm

Hi, we recently purchased a dragster for our daughter and I was wondering what is typically done for rear tire pressure when trailering the car. I noticed tonight, that the rear tires (33.5x17x16 Goodyear) were super hard, when I checked the pressure, I found them at 15. Is it best to air the rear tires up when trailering? Or leave them something closer to the race pressure? The car is a 235'wb hardtail

Right or wrong we always trailer ours at pressure we end the race with. The trailer does not move with the car inside without a air bladder under it.

Ok, thanks. I had heard of the bladders, but never seen one yet. Do you use that under the engine for support where most of the weight is?

No we place it under the seat area. There some cross bars under the seat area. That is where we place the bladder. Strap the car down and inflate the bladder.

When I was hauling a dragster put 10lbs in tires, strap it down and put
a block under the crossbar at the seat area. Them chassis will flex
more then you think and cause cracks when they bounce up and down.
I run a mini chassis bladder under a jr dragster.
