I am going to be getting new tires for my Blazer and was wondering if anyone has used this size combo and how it works..
I am leaning towards 20-11-10 on back and 21-7-10 or maybe 22's on front..
The reason for dropping down on the rear is to get a little more bottom end and i figured that i would have to go smaller in front to even things out a bit.
The only thing that i'm concerned about is lossing ground clearance.. is anyone running this combo and are you happy with it ???

 

If you want more bottom end power it might be better to drop 1 tooth on your front sprocket. It will give you similar results as changing the tire size and your ground clearance wont be affected.If you ran 20 inch rears in the trails I run on you would be hitting every rock in the trails.The 24 inch rears I run give good ground clearance and they're the stock size for my bike too.
