I want to buy new tires for my 300ex. I ride all kinds of terrain, Sand,dirt,snow,water,mud,trails. I ride it all. I need to know what would be good front and back tires for those terrain. I also want it to increase my top speed. I really have no clue about tires so lease help me out.

 

I think 22x11-9 sur-traks may be a good choice for your bike. They are good in all-around conditions and seem to wear at a good rate. They are also a fairly light tire, and have a good hookup style for sport quads. I run them on my 400ex, and it is great being able to blast through mudpits without having to worry about getting stuck everytime as I did with stock tires. These will also fit on your stock rims. For increasing top speed though, I would gear it up through the sprokets (IE. bigger front, or smaller back), as that would add less weight than bigger tires for higher gearing. These will also fit on your stock rims. Hope this helps your decision making.

 

I have some bandits mounted to my stock wheels. I think they hook up best for me. I've rode them in just about everything. you'll probably want to stick to your stock size(22").
if you think you can sacrifice some of your low end you can go with a 14 tooth front sprocket to get your top speed up.

 

I'd suggest that you get a set of realtors for the rear because they are a great tire for snow/mild sand.
Read the signature to see what i use. I love that setup but i dont ride in any sand (there's none around here!) and in snow the turf tamers arent the best.

 

i got bandits up front and GbC Dirtdevils in the back all on stock wheels. i also ride in all conditions and this combo. of tires seems to work out really well. i dont know if they increase top speed though.
