I have just entered the exciting world of Mountain Biking
after many years of road riding. My first hint that I
have a lot to learn was noticing the pressure rating on
the sidewall was 40-80 psi(quite a range!).
I know on a road bike using maximum rated pressure rolls
easier,protects rims, avoids snakebites : , and lessens
flats.
I am under the impression that I will have to use different
psi for different conditions to compromise traction versus
rolling resistance. (My second hint of "a lot to learn"
was trying to ride up a near vertical wet grass and gravel
trail.- This stuff is FUN! :-))
I would like to keep damage to a minimum while I figure the
optimum psi compromises. Any hints to get me started? What is
your preferred pressures for various conditions? e.g.
potholed gravel roads, smooth trail, *very* rocky/rough
trail, combination paved and gravel and trail rides, etc.

| 265.1 | Dirt Bikin'; the low pressure sport.... | MENTOR::REG | Who is Sylvester McCoy | Tue Apr 14 1987 11:43 | 15 |
My recommendations:-
15 - 20 Slime covered rocks, the *WORST STUFF*
20 - 30 General Trail conditions, mostly dry, gentle grades,
firm ground.
30 - 40 On and off road
I wouldn't go over 40 psi on mine (2.125s), and I wouldn't go
below 15 either.

| 265.2 | more psi? | MANANA::RUDNICK | Wed Apr 22 1987 15:35 | 9 | |
I think I'd go a bit higher than 40psi on the road. Especially
if you get into using the bike to carry any weight as in commuting
to work carrying clothes, shower supplies etc. I forgot to up the
pressure in my tires last year after some trail riding, headed to
work one day, started getting a little hyper on the bike (ie. jumping
curbs, roughing it etc) and ended up with a snake bite. Just a
suggestion.. collect your own grains of salt...

| 265.3 | Less is best, but stay light... | MENTOR::REG | Who is Sylvester McCoy | Thu Apr 23 1987 10:10 | 6 |
re .2 WudYaAckchulyCommuteOnTheATBAndStayOnTheRoad ? Only time I
commute by ATB is when I'm plannin to go through the sand pits and
apple orchard, else its skinny tyre time. Whatever my tyre pressure
I try to stay light, i.e. banging curbs is gonna get snake bites,
so jump 'em.
