a lot offroad!...
130 is to big...
I use a 120...
fat tyres sit on the top of a lose surface... the grip is
found on the hard stuff below... thats where a narrow tyre
can cut though to where the grip is...
no one has ever made a tyre of any size that grips to
lose gravel etc... they grip to the hard stuff the gravel is sitting on..

if yer ride sand or mud alot then a wider tyre will help...

take a look at rally cars... more gravel on the road the narrower the
tryes they run... why no one wants to go first... the fast guys are the ones
running on the swept surface...
