ROCK HARD TYRES CAUSING PROBLEMS!

[fredperrybruce]

HI, I HAVE JUST BEEN GIVEN A PAIR OF ZIPPY 1 TUBELESS TYRES FOR MY PX SO...........

I TOOK MY OLD WARN OUT S83's OFF AND PUT THEM ON MY SPLIT RIMS!!!! (WITH TUBES) OBVIOUSLY

NOW THE PROBLEM IS WHEN I FILLED THEM UP WITH AIR 17PSI FRONT/ 26 REAR. THEY FEEL REAL SOLID , THEY FEEL ROCK HARD EVEN WITHOUT BEING PUMPED

TOOK THE SCOOT OUT FOR A BURN AND IT SHOOK ME TO DEATH , I ALSO JUST REPLACED THE FRONT SHOCK TODAY (WHICH WORKS WELL) BUT TYRES ARE LIKE ROCKS.

DO I NEED TO DECREASE HOW MUCH PRESSURE I PUT IN THEM OR HAVE I MADE A c**k UP SOME WHERE??

TOOK THE SCOOT TO THE GARAGE TO GET PUMPED SO I KNOW ITS THE RIGHT AMOUNT!

I'd certainly not run them any lower than 17/26.

No personal experience with Zippys, but aren't tubeless tyres by their nature generally more rigid in the sidewalls?

and S83's are one of the softer walled tyres from what I've found..

I'd not run 17 anyway. 18-20 on the front, certainly with a stiff shock.


Instinct tells me that it's the shock that's the problem, especially if it's a disk model. It'll be working harder than you're used to to keep the front tyre on the ground, that means you're going to feel every ripple in the road.
