I contacted Pirelli about my Euforias tracking rain grooves on the freeway. They had me take the car to an authorized Pirelli dealer, which I did. A month and a half later 4 "new design" Euforia tires arrived. While I was not charged for the new tires (the old ones only had about 2,500 miles on them), the shop scratched the heck out of my rims so I DO get to pay to have them fixed.

The short story is that the "new design" continues to follow rain grooves. Pirelli is ignoring my subsequent contact efforts. What I would appreciate is anybody else who experiences this problem sending me an e-mail ( moco_head@hotmail.com ) so I can inform Pirelli in writing that there is a problem, and it is not unique to me.

Thanks.

 

My Pirellis did the same thing, which is often called "tramlining". Rain grooves, roads made concave by truck traffic and bridge venting grates all can cause it. It's not a problem unique to the Euforias, but similar designs as well. My Goodyear F1 GS-D3s dont have anywhere near the tramlining as the Eufs did, but their tread design is totally different.

 

I have the same tires and yes, I experience the same thing with the grooves on the freeway. Luckly, not all freeways have those gooves. But I have learned to live with it. I am trying to wear down the run-flats so I can buy regular tires.

Good luck on getting the manufacture to do anything. I never tried, because I thought they won't respond. Good luck.

 

Well, maybe if enough of us raise the issue we can get Pirelli to pay attention and take care of all of us.

Thanks and let's hope to find a fix!

 

Red05MCS,
Sorry to hear about your rims. I'm surprised Pirelli sent you the tires. Do you get to keep the four used tires as well?

Runflats (and high performance tires with short sidewalls) often tramline and it's a common problem no matter which brand you get. See
http://www.tirerack.com/a.jsp?a=EZ3&url=/tires/tiretech/techpage.jsp?techid=47
Talk to alex@tirerack.com for more ideas on how to cope with it.

Quick suggestions short of switching to non runflats-
Reduce air pressure- don't allow overinflation-try 34 psi
Alignment- don't be excessive setting toe out or camber
Drive in the smoothest lane (left) when safe
Watch for worn suspension parts- this adds to tramlining

Note that narrow higher profile tires tend to resist tramlining quite a bit so that if your roads are particularly bad (like California highways or in areas with lots of truckers) then an option would be to steer clear of wide low profile tires when upgrading.

 

tramlining sucks...but a lot of performance tires do it.


Im running 50 profile tires and soft sidewall, so no tramling even at
+42 offset. (GS-D3).

 

This is some good info. I have Euforias too on my MCS and experience the same thing when on Hwy's. From what limited info I know about Pirelli's, they do tend to be on the soft side when it comes to the tread compound so that would explain some of the wear problem caused by tramlining.

 

Unfortunately Pirelli did not let me keep the old tires... oh well...

I am at 34 psi on the nose and no joy. I even tried 30 with no luck.

My alignment is all stock, and the car only has 3,500 miles on it so there is no worn suspension.

I expet the car to follow truck ruts and the like. My issue is just the fine drainage grooves cut into the concrete on So. Cal. freeways. Makes the car go side-to-side while driving straight down the freeway. No steering wheel movement whatsoever like hitting truck ruts.

 

Try 35 PSI, then if not, ditch em!
Good luck

Alex

 

I find the problem to be worse at high psi... but it never goes away... unless the road does.

 

Are you of the opinion that i should try working with Pirelli or just spend money and replace them ?

 

Try, and see if its liveable.

Alex

 

They just need to cover all the freeways with the nice rubberized asphlat like here in phoenix. it is sucha nice, smooth, and quiet ride!

 

My stock run-flats would tramline like a beast, nearly throwing me into the guard-rail on a local bridge. However, since getting the Avons, I have been able to drive across that bridge without even touching the wheel.

Ditch the run-flats. Carry a spare, if that's your main reason for keeping the run-flats.

 

Aysemetrical tires like the M500 by Avon.



offer the best rotation capability


This helps with tramlining, and noise dramatically!

My Pirelli's tram lined badly. I recall driving away from the dealer the day of buying the car and thinking a wheel was coming loose! After 12k miles, I did find the severity had decreased to the point where I could live with it. But, I then hit a very bad pothole during a heavy rainstorm at night and damaged the left front side wall (blew out the side wall so that the wire mesh reinforcing was visible). Tire remained inflated and drive was fine. Got that tire replaced with a new Euforia ($260!!!) and had them put it on the back wheel...but now the tramlining is back full force.


I'm convinced it's the centerline of the tread pattern that gets caught in the Southern California freeway grooving. I here Dunlop runflats have a completely different pattern and show little or no tramlining.

Mike.
