stock tires on my scrambler where 23x7x10 and i went down to 21 will that matter someone told me today it would hurt something on my 4wheeler when i put it in 4x4 thanks

 

If you're going to replace the front tires, you have to replace the backs with smaller ones as well. You have to maintain a 1" difference between the front and back tires. A 2" smaller front tire will require a 2" smaller (or 20") back tire. This is needed for the 4 wheel drive.

 

well i have 22inch all traks on the back right now
so will it hurt anything on my bike if i leave it with 21 on the front and 22 on the back or do i have to change it to 22 or 23 for the front

 

Stock is 22"- rear 23" -front, you're wanting to go to a 21" in the front this means you need a 20" in the rear, how ever many inches you go down the the front you need to do the same to the rear, in this case it's 2"
I have seen guys do this, it will work just don't enguage the 4x4 on hard surfaces like asphault, dirt etc. If you need the 4x4 in somthing like mud it would work find becasue there's not that much traction to do damage

 

<u>From Polaris

Does it matter what tire size or type I use?</u> Our ATVs have an 18 - 22% difference in ratio between the front and rear tires with the rear tires having a lower ratio. This means that the rear tires must spin 18-22% faster than the front tires for the front hubs to "wedge" and the ATV to become 4WD. If someone was to install larger rear tires this would make the ratio difference greater and the rear tire would have to spin even more than 18-22% for the front hubs to engage. The reason for this is so that when the ATV is in 4WD and turning, the inside front wheel is still turning at least the same speed as the rear wheels and the hub will not engage.
If you are planning on installing larger diameter tires and wheels on your ATV, please remember that you must maintain the proper ratio between the front and rear wheels. I.E., If you install one-inch larger diameter tires on the front of your ATV, you must install one-inch larger diameter tires on the rear of your ATV. This principle will also apply to the use of larger wheels. <u>You must retain the original ratio between the front and rear wheels in order for the Demand 4 Drive system to operate safely and correctly.

</u>In your condition you are actually 2" smaller diameter tire that you need on the front with a 22" or the rear. Your Front wheels are spinning faster that they did with the 23" tires.
When your 4x4 does engage it will be harsh,(The gearing is for a 1" up diameter difference) and you could actually be disengaging prematurely. While it may be true this condition will work, In my opinion you could be causing premature wear or the front drive components.

 

will 22inch tires on the front work or does it have to be 23 cause my friends wolverine has 23 all around is it different with different 4x4. I found a cheap par of kenda claws that are 22 but if i have to have 23 ill get 23 so i dont hurt anything

 

I don't know if this helps any,but i ran 22x11x10 sand paddles all the way around for 3 years with not one single problem.And yes that is with the four wheel drive engaged.That was on a 96 scrambler.Later.
