Stu blaster 36-17 psi for best slide

[JerryProkop]

I bought a new car, it is a Desert Dynamics prerunner about 3500 lbs estimate with 680 crank hp. What is the best psi on the 36 sand blasters to slide? The car doesn't have cut brakes.

I run 14-16 my car slides great but she is pretty wide

 

[JerryProkop]

Mine is 97 wide in rear

I run 20 in the rear. Bump up to 24-25 of the sand is wet. Definitely much better sliding / wheel spin with the higher PSI.

 

[Dodd]

18 psi for me for dry sand and about 5-psi when wet. 101 wide 2900# approximate.

less air when wet???

less air when wet???

Only if you want to break stuff.
Or wheelie everywhere.

16 pounds all the way around for me. I don't want my car to slide too much though, I want it to bite.

 

[Dodd]

I meant +5 ish

I run 15 - 16 Rear and 13-14 Front mosyt of the season unless it rained and the sand is wet - I like the slide !

I run 12-15 in rear, Do not like dents or bends in the front rims, I keep mine around 25-28lbs, when i ran them around 10 in the front, it would dent the rim over time,

Desert dynamics and slide typically doesn’t go together lol
Higher the psi usually will give you more slip and equal more slide
My SU I run at 10 rear and 8 front. Only ever use turning brake when I want to flip car around and into a wheelie = asking to break shit

I too have a desert dynamics prerunner but just over 400 to the wheels. I run 20 psi rear (36’s) and 18 front. I can slide it all over at that tire pressure with the right throttle application.

23 in the rear
9 in the front (must have bead locks)
i want the rear to slide and the front to bite!

It's the ratio that counts, not the value. More than the front. If you run 30 up front and 28 in the rears, it'll still plow like a tractor, just a tractor with lots of wheelspin.

Run as little as you can up front for better compliance/chop/easier on parts. I have a super light buggy, only run 4psi up front, 11-14 rear. My Jeep has almost your entire buggy on the front axle alone, I run 8psi in 15" 35s (read: lots of sidewall leverage). No beadlocks anywhere, have only lost a bead once on the buggy, never in the Jeep. Jeep is used as a recovery vehicle, and had been nearly everywhere at "we're getting this shit out before the sun goes down" speeds. Wife's Can Am, running 14" 32s and no beadlocks has been at 8psi for 10 years now, never lost a bead.

With beadlocks in a buggy, I doubt you'll lose a bead so long as there's some air in the tire and you haven't crashed. Even without beadlocks, 7-8 is pretty safe.

STU 12.50 in the front on mine and run about 10. This is my first year with the STU 36 Blasters and I have been running about 16 to 18. Ran 20 when it was wet. Never had a clutch issue until I put the blasters on. Used to run 16.50x17 Dune Sports. Have a spare set of tires with the Funco 14.50x17 Dune Sports and run about 16.
