im looking to put some new rubber on the back of my 300 as my first mod considering the feact that these stock ones suck...i was thinking about some irazers or holeshot hds.....i would need these tires to be good for mud and rock mountain type trails as well as raceing

 

Holeshot hd's might be a good choice then if you ride in really rocky conditions, otherwise irazors and regular razrs and kenda klaws would be good choices

 

holeshot HD's are the way to go...great in mud..its almost in possible to get stuck with them...bigger sidewall and really thick rubber so they are great for rocky trails and mountains...they will make a perfect racing tire too..out perform any other tire holeshot has every come out with...i would take them over any of the razr's...the HD's are a great price too...youll see a huge difference with them from your sh!tty stockers...

 

ya but will i have to much traction cuz i like to throw my quad sideways through turns so will i be able to break the wheels lose

 

As you get a couple of mods it will be easier to throw the bike around, but if you use your power right you should be able to get some slidage

 

you should have no problems...ya your gonna have a lot of traction but still youll be able to throw the rear end around a little...and yeah like fullthrottlez400 said mods will help for sure...
