Long story short...
trying to add an additional 5 -10 psi

I have had no luck bumping my tire pressure up past the sidewall recomendations.

Even with new professional all wheel alignment on new sets of tires

This is the 3rd set of tires that started cupping (every other tread block seams to raise out of tread alignment)

This is NOT all on the same car, NOR is it all of the same tire brands or tire sizes

Just bad luck - maybe

Hopefully these tires don't seperate on me when i hit 70mph cruising the intersate

Back to riding on 3 under psi for me.


$$$ back to tire shop $$$:mad:

I would vote for the bad luck theory. I've been running 70-80psi in my Integrity's(44psi max) for a year now with no apparent problems.

Over how many miles? What kinds of tires? Specifics would
be useful here...

have you hit any bad pot -holes at speed ??

from my understanding larry gets to drive on rutual roads with no other driver in sight! and if there is he would gladly get out of the way by any means possible.

And his coasts would last 10 times longer than his pulses

Cupping is often a symptom of tired shocks or struts or something loose in your suspension. They probably would have found loose tie rods etc. when they aligned your wheels, but weak front struts aren't so obvious. Less tire pressure would probably reduce the problem but have them check your struts next time you're in.

Vehicles that always carry a ton of weight in back also tend to cup the front tires, so if you have a bunch of sets of barbells in your trunk...

You don't need speed to feel the pain in his car. I hit a small pothole once going about 20 MPH and got bounced around like a pong pong ball... :eek:

my truck hurts my back on some :mad:

I've run my Michelin Hydroedges in the mid to high 50s most of
their life, and the only cupping/feathering began on the right
side most likely because of a slight rear-wheel toe-in which has
recently been corrected. It was only on the inner part of the tread,
implying that the negative-camber of the rear end put more weight
there; once that tire was swapped to the front the increased noise
was obvious. But none of it is serious enough to affect handling,
you can barely feel anything with a hand, and only time will tell if
the rear-end shimming will slowly begin to correct the right-side
pair back as they're rotated fore and aft. I haven't even swapped
them back the way they started yet, but will soonish.
.
I don't think running them any softer would sway it either way, so
I'm going to run 'em till they die. Once this type of wear has
started it is probably a self-sustaining thing depending on how
the tire surface oscillates against the road, but I don't expect
these things to magically turn themselves into offroading knobbies
anytime soon.

I will get tire specifics when i get out to storage shed.

I figured that road conditions play a factor but with the vast array of rubber tread that i have lost due to cupping i think that psi is not helping for sure

Watch out for your pets and small children because:
We have Smokin' Pot holes deep enough to see running molten lava. Holes on bridges and overpasses that go all the way though the bridge!, Washboards that will spin your car right off into oncoming traffic.
I am located in central missouri dodging those land mines are of my normal driving routine

rare but when I have to go out on gravel road I drive 5 mph and still end up having to tighten up bolts on fenders and align door panels when i get home

Sounds about right for Missouri. However I have found that roads are far better as you get closer to the capital building.....

Have you had your tires balanced lately? That could be contributing to the cupping problem. Also, high speed turns could cause this.

I would get the tires balanced, rotate front to back every 5k miles, and slow down in the turns and s-curves. Problems with air pressure will give center wear for over inflation, or both sides wearing for under inflation. You would have to have SEVERE shock/spring problems to give you cupping from that.

Wimp!;) Kidding, kidding.:D

Phil, you are correct. I do get to drive on country roads and the traffic is usually pretty light. I do my best to stay out of their way when there is traffic but, if there is no oncoming traffic in a passing lane and they don't go around, they're on their own.:p

COMP, I have hit a few potholes at 30-35 mph. One of them was such a jolt that my wife's head hit the ceiling pretty hard. That was back during this past winter and the tires are still fine.

And the wife???

And the wife???

Sounds like she's still a "Mrs" so it couldn't have been too bad ;).

And the wife???
Well, she was good enough that I could joke with her that no one could tell the difference between before and after; she even laughed about it.:p
