i have the new TRX450R and i put a set of Razr rear tires mounted on douglas .190 aluminum rims on it. i have the tires at the pressure suggested for the stock tires, but they seem to spin extremely easily. i'm used to riding mostly sand, but when i used to ride my 400EX on trails the stock tires hooked up better than the Razrs do on the 450R. should i lower the tire pressure, or what?

 

First, what tire size and rim size did you get? If the razrs are stock size just let the air out a little. Try 5 lbs of pressure.

 

If you ride mostly in sand why in the heck did you buy a Razr???

 

i have paddles for the dunes, and the tires are almost the same size as stock. the recommended pressure for the 450R stock tires is 4.7psi +- .7 maybe i'll try jus under 4 next time

 

Cro, Keep in mind, The 450 has a lot more power and torque than your 400 did. Or it sould have anyway.

 

With my warrior I have no problem spinning razor2's even on sharp corners, with 5 psi. I would of recommended the razor2's, they probably would of done better in your situation. That should be your next choice probably, but that's just a suggestion. Just drop the pressure a lil' bit for now, that's the best you can probably do. I have no idea why people say they have problems getting the rear end out with the razor2's, it seems pretty simple.
