Tire size making bike squirrely?

[radish150]

I have been using my 99 WR for quite some time now with street tires and recently decided to take it out out and use it like it was meant to be used. When I took it out, in the dirt it feels slightly "wiggley", or maybe like the front and rear are not wanting to track exactly the same. Anyone have any ideas what might be going on? The rear tire (sorry I know you need the tire size... later) is a bit large, and not very "round". Anyway, just wondering if anyone had any ideas what might be going on. Its not extreme this sensation, but something is not quite right.

Thanks

Could be a few things - I take it you're on more open trail at higher speeds? You definitely want to drop tire pressures down a bit. Otherwise, it could just be crappy tires for offroad and/or just a factor of getting used to the "slip to grip" part of dirt riding!

Yah, thats right, "on harder trails" I´m feeling it most. Yes, I´m pretty sure they would qualify as crappy tires, "Duro" them is, YAY TEAM So what would be a good place to start for tire pressure? I think they are at the recomended 32 give or take a lub.

damn 32psi? i ran 12-14 psi in a dirt tire on my bikes that worked great

Gee, thats what it said on the tire... Suffice to say that less is probably better and I will try it.

Thanks

This is normal for offroad. You have less traction. Once you get used to it, you'll learn to like it.

Are you shifting your body weight properly? Do you know what I'm talking about?

For now, concern yourself just with the front. Just make sure its pointing where you want to go. Let the rear end dance around a little.

btw.. whats with the large, "not very round" tire?

have to let some air out.....I had the same feeling....too much power capitan!

I think I'm running 14-16 in the back, and 10 - 12 up front. Made a huge difference!

32 psi will make the back end of a WR 450 squirrely in dirt, and I don't care what kind of tire it is....

Manual call's for 15 psi...I run about 12-13 in a Maxxis Desert IT (Mount one, and you will know why...)
