I know the feeling you are talking about. I run 19" fronts sometimes situation dependent and have felt the "busyness." So you crank up the stab a few notches and you are back to normal. Sorry, never have gotten excessive oversteer that would cause loss of control(spinning out.) Out of curiosity, what did you do to solve the situation on your 300? Did you ONLY switch to a new Holeshot 22" front? Or did you switch the rears out too? Or did you just ride them until they were toast before putting something else on? Were the rears brand new as well? Did you change the suspension up so the ride height F/R remained the same? That is actually a point in favor of using the oem size fastfiveO. Although you will find that many of the aftermarket tires vary and one manufacturers 21" may be closer in size to anothers 22" and yet anothers 20". Probably best to stick with just one manufacturer for all the tires.

 

Never ridden on IRazrs. The Razr rear Razr II front is a great combo for just about any trail condition a sport quad has business in.
Original Razr fronts also work well, and are cheaper than the II's. I have had good luck with ITP product also, I just don't see an overall performance increase to justify the price over the Razr rears.

 

I tried the iRazrs. The front tires are nominally 22", but actually they are taller than that. The fronts give razor sharp steering, and being radial you get a very nice ride.

The rears were another story. While the radial ride was great, the traction blocks were spaced so far apart that the traction was abdolutely terrible for desert conditions. They might work well in other conditions, but I don't know.

Another choice if you are an eastern trail rider (softer more loamy conditions), might be the Holeshot H-D's.

 

go with size 22 in front and 20 in back. i have a 400ex and i would go with 14 front and 38 back sprockets. i run with a friends banshee. stock both.

 

i have ITP spider traxs 22-12.5-9 on the rear and stock tires on the front
