Front Tires For Sand Use...What Size??

[jayzx750]

I have 21x12x10 Sand Skates for the rear and am looking for a proper size match for the front. I see 21x7x10s and 22x8x10s listed for the Blaster. What should I run at Glamis on the front of my Blaster?? I run the 22s up front on my Banshee so that seems like a logical choice, but maybe the smaller tire because it's a smaller machine or the larger to float better.....
I'm so confused....=)) j/k.

Thanks, Jay.
