Start by giving us the weight of your rig and what kind of comps you do then maybe we can help.

Mi rig ways 1275 kg...
And we do comps in al kind of terrain.. But will use the stickys when it is stony...

what Steyr are you using?

1275 kg =2800lbs for the Amreicans:flipoff2:

No offense, but if you're competing, you better be able to figure out your own setup! You should ask your fellow competitors, I'm sure they'd recommend somewhere around 55-60 psi!:flipoff2:

hey hey hey friends.. I will ofcourse try it out.. BUT Im the first in Scandinavia with Sticky Iroks... testet it out a litle an a comp in Sweden, but I think I went with to much air...

I really likes the sticky compound but I need to break them in first I guess...

I tried out 45 psi, but that was maybe a litle soft.. and ofcourse its al about drivingstyle also..

Sorry, but my question was not correct...

The thing I wounder about is more like:
What airpreasure do you run on your 42" stickys, and how is that compeared to what you have run on your normal IROKS...

The european Championship is comming right up, and I havent have much time to test it.. so Im just looking for some advise...

Its not a Steyr engine, they are my mains sponsors and helps us out with other things..
The Steyr engines would have been to big and heavy for my use...

It doesn't look like you have to worry about getting flats, so you could run a little lower air pressure.
Probably between 5 psi and 8 psi. (American). One psi more in the front tires.

Maybe my english is bad, or I messing up things..
But I thought that 1 bar was 15psi (ca) ???

I think one bar is 14.7 psi. Am i reading this right that you are running 45 psi in your tires?

sorry.. my mistake..
On my normal 39,5x13,5x15 I normaly would go as low as 3-4psi
testet me new stickys with 10psi, but found them way to hard, and went down to 6 liked it then, but still hope they will be better when I breake them in...

Thanks for help..

My expiriense with my sticky's (Pro Comp XCC) is that I can run a bit more pressure on rocks without lack of performance compared to normal tires.
Then I get less bounce and better steering.

Running 6psi all round with mine...the fronts are also 2/3 full of water.

OH YEAH...you might wanna grid off the concave part of the outer lugs to avoid tearing of the upper lug material.

Running mine backwards until it comes time to crisscross them.
