Solution to Creaky Open Pros???(6 posts)

Solution to Creaky Open Pros???Tbonefitz
Oct 10, 2002 5:42 PM
I have the dreaded creak in my Open Pros and I think i found the problem but I need some help to confirm. The max pressure as listed on the wheels is 117 lbs/in2. My wheels started creaking like crazy when I switched from the original tires, Mich Axial Carbons to a set of Vredstein Fortezza Roads. I love the Vredsteins at 145 lbs/in. After greasing all the spoke nipples, etc etc to try to stop the creaking to no avail, I decided to just lower the pressure to see if it would fix it. At 80lbs, no creaks. 90 no creaks. 100 no creaks. 110 moderate creaks. 120, creaks. anything higher...lots of creaks. If you have the same problems, try adjusting the pressure. I am curious if this is just my set of wheels or if they all act this way. If so, I guess I will start using tires that run lower pressures. If not, i am going to buy new damn rims. Thanks!

I had a similar problem, here's what I found:

Basically, 700x23 tires can't be inflated more than 138PSI. I was told distorts rim and actually reduces the tension on the spokes. The Vred's ride nice tho, huh?

Guess I'll get some new tires. I can't see spending a couple hundred dollars to make a $35 tire work. Now if I can just find a tire that feels as nice as the Vreds...Definitely a smooooth tire. If your rim can take it they are excellent. They'll make my commuter feel better at least. Thanks for your help.

Just because a tire is rated to 140 psi, there is no reason to pump it to that pressure. Within reason, a Conti, Michelin, Vredestein, Vittoria, etc. will all ride about the same at 100, 110, or 120 psi. Max pressure rating is just that, not necessarily the pressure you must ride at. Many people are riding Vreds at the rated pressure when they should be at much lower pressures.

I would agree.. I don't know how much you weigh, but dude 140 is a lot of tire pressure.. Why not just ride on straight rim, that has to be what if feels like 8)
If you are not a heavy rider I bet 110-120 would be sufficent tire pressure...I just bought those tires and no way would I put that much pressure in them...one racers opinion

They did feel extreeeeeemely fast at 140. I'm still learning all this stuff and I must have misunderstood. I thought that the reason for the higher pressures was for reduced rolling resistance and that the tire would perform better at these pressures. However, in light of your recommendations, I will experiment with tire pressures for comfort and as long as my rim doesn't creak I'll be a happy camper. Does the risk of flats change at all with tire pressure? Assuming of course, that the tire is within the MFR's recommended pressure. Thanks again for the valuable advice on the pressure thing.
