I am a newbie so if this is answered somewhere else please forgive and point me in the right direction

I looked at my tires today and the recommened inflation pressure is 50 - 85 lbs. I have 45 lbs in them now and am afraid they are going to pop they are so tight.

Is this normal and should I go ahead and add more air?

Thanks in advance,

Terry

G'head and add air.
If they're rated for up to 85 psi then there shouldn't be any problems even at max pressure.
Yeah...they'll feel tight, but they won't go BOOM.

If you have another pressure gauge, you might double check the amount of air in the tires.

I had a floor pump with an inaccurate gauge on it. I didn't realize that it was not correct until the tire blistered up through the valve hole in the rim and popped. After some testing with other gauges and pumps, I found out that the built-in gauge measured 20 lbs less than what was in the tire.

Air it up until air starts coming out, then back off 2 lbs. ACTUALLY, it's a toss-up between how hard do you want to push and how much of the road/trail do you want to feel.

First make sure your gauge is accurate.

As a general rule, higher pressure means you go faster, but you sacrifice some cushion. Lower pressure gives a more comfortable ride but it makes the "engine" work a little harder. Also, lower pressure puts you at greater risk for pinch flats, which is where the tube gets stuck between the tire and rim and gets cut.

thanks for the help everyone! I will add more air and see how things go
