Tire Pressure

Recommended Posts

I have an '07 BF 650 i with ITP Terracross'

I run 3 PSI in the front and around 4-4.5 PSI in the back.....

I was running 6 front and back and the ride was pretty stiff.

Now, I love it....

I ride a lot of rutted trails with a decent amount of rocky trails....



p.s. Toss the stock Dunnies!!!!!! They BLOW in the mud...and I'm not talking mud bogs either!

I agree....depends on the Ply Rating of the Tire.....How Heavy you are ETC. ETC....Mainly.....what Feels Comfortable to you....

Quick little Quote I found in 20 Seconds on Google


I can’t begin to tell you how many times I have kicked someone’s tire, only to find it hard as a rock or as soft as mashed taters. ATV tire manufacturers recommend tire pressures as low as 2.7 psi to as high as 10 psi. What is the correct pressure for your ATV tires?

First, look for the orange and white sticker (it’s usually on the left rear fender) on your ATV. Front and rear psi may be different, so don’t assume all tire pressures are the same. When all else fails, ask your wife what the owners manual says (most guys don’t read owners manuals).

If you’re going to be running the Grand National Cross Country series like I do, or if you're riding a lot of rocky terrain, you might want to increase the tire pressure above what is recommended, I run as high as 10 psi at some races because of the rocks.

Be sure to keep your tire pressure the same, left to right (both front tires should be the same and both rear tires the same). If one side is off by as little as ½-pound psi then the ATV will pull to the low side.

Know your tires. If you have aftermarket tires, follow the manufacturer's recommendations, but be careful not to mistake the sidewall higher pressure (as high as 25 psi) that is needed to bead the tire on the rim for the correct pressure for normal riding, which is much lower.
