Bias Ply Claws Pressure on and off road

Post by MR 1JZ »

I have searched high and low around these parts for an answer to the above question...

I have done some googling but here: http://www.jpmagazine.com/techarticles/ ... to_07.html has said they can be run as low as 3PSI?!

Ive got 35x13.5x16 Bias Ply claws on my bundera and I am wondering what PSI is good for them off road and on road.

They are running on 16x8 cruiser rims without beadlockers.

my bets would be, 35-40ish baring in mind that when they heat up they will expand.

and bout 18-20 off road

Trial and error would probably be your best option. Onroad start at 30, then go for a run, see if they go up by much more than 4psi, if they do, then up them a few psi at a time.

Are they new? or used.. if they are used, they maybe a tad softer, and bag easier.

They could probably be down to 3psi - depending on what rig they are on, and you would want beadlock rims without doubt (at less than 10psi too probably)...

they are used mate...ok no worries i wont drop them below 10psi...I havent really tried them below 18psi off road and while they are good from pictures I have seen they arent really even close to bagging even when on 2 wheels...

i might try them on 11psi this weekend

drop the pressure in your driveway as low as you think is appropriate - i'd say for a bundy prolly 8psi would be "ok" - although you wouldnt want to go doing fast corners on sand like that. - anyways - let em right down and really rock the car side to side (even get mates to help) - its fairly obvious if the sidewall is moving too much. I did this on my zuk at 2psi (31s) and it looked scary, however at 4psi there was a noticable stiffening of the sidewall. so now i know i can drop to say, 5psi without too much hassle - but im also running tubes, so mud etc in the bead wont give me flats anymore =)

yeah I gave them a run on 11psi today...they worked fantastically!

I am going to invest in some beadlocks though I think

i wouldnt worry to much about beadlocks.

Running a 16x8 and a 13" wide tyre, i think your tyre will go flat
before losing a bead.

i run 33x13 maxxis on a 16x8 at 8-10 PSi.
previously run a TSL 12.5 wide in a 15x8 = same thing
