Believe me, it will help having more air in there.
ten pounds makes the bike unresponsive. Its good for learning straight line stuff. But from the pics of him, he isnt a newbie anymore.
Even 25psi will help, it will feel wobbly at first, but you have to push through that.
I was so stubborn when my friends said to run 30+ that I refused and kept with my 18psi.
Now I run 40psi, and dont know why I didnt listen. Bike circles so much nicer and easier when the rear tyre has decent pressure.
Go on stuntride.com and ask... Yourll see loads of guys saying EXACTLY the same, and alot of the top boys even run 65pounds plus!!!!
Just so you can see, I do ride myself, im not just passing on 2nd hand advice
