Mountain Biking - tire pressure

What pressure should you use in a specialized hardrock for mainly street use? I just bought the bike last night, and want to ride for exercise, riding mainly around my neighborhood. I plan on riding in local forest preserve trails after I get some experience, what air pressure would be good for light trail use? TIA

WELCOME TO BIKE FORUMS!!!!!!!!!!

Start out around 50 psi then try more or less. See what you like. Your tires should have minimum and maximum pressure printed on the sides, make sure you stay in that range.

I keep mine around 25psi... 30 at the most...depends on the trail, and general conditions

no motor,

for street use go upwards of 60lbs - but do check the rating on your tires.

I went to slicks on my mountain bike - Fatboy 26 x 1.25 running 100lbs - was wonderful for low rolling resistance. I put almost 1000 miles on these & have just gone back to the mtb tires to do some off-roading.

When riding on pavement, 45PSI, when on the trails, I'd reccomend 30PSI.

i do 40psi front and rear. nice balance for trails and road.

I like to run about 3 in the front and 5 in the back. Thats a good balance for me. If things are wet I'll drop about 2lbs in each.











Just kidding, everyone has given some good advice. Only so much you can say on basic tire pressure and I'm bored.

On the trail, 32-38 psi, just depends on the conditions (and tires). As far as the street, I use Specialized Nimbus Ex 26x1.5. I air them up to 100 psi. I get a flat on extremely rare occasions, oh, by the way, I somehow get tears at the valve stem, though :eek: . Anyways, 100 psi on the street. Good Luck.

i wouldnt pump them up to 100 if they're any wider than what G4 said, id say 60 at most. but for trail riding, i stay in the 30's

I hit some singletrack for the first time a few days ago. One of the things I learned very quickly was that tire pressure can make a HUGE difference in the ride. I started out with about 45psi and was getting beat to death on the trail (did I mention I have no suspension?). Anyway, I dropped each tire about 10-15psi and it was like riding a new bike!

Oh yeah, another thing I learned very quickly is that clipping a tree with the left side of the bars can result in a less than upright position!

I like whatever is the max rating for the tires. That's true for trail, street -- whatever. That gives the fastest, easiest ride. Like FLBandit says though, without suspension YMMV. :)

A perfect example of how different things work for different people. Budster prefers high pressure on the trails. Most others prefer low pressure. It all depends on what works for you, your riding style and the trails you are on. Experimenting is key.

for all around riding ,street and light trail, 400 KPA (metric)
that translates to about 62 pounds per square inch.
just my opinion of what works great for me, but every one need's to experiment.

60psi is the best for street riding because you can hit curbs as hard as you want without the tube pinching. but if you want more traction, id say about 30psi for trail-riding

i use 80psi of helium
