Goodyear Efficientgrip tyres

Just checked my Alfa Brera 2.4 's tyres after a trip. ( 225 x 50 x 17 W extraload Goodyears )
three tyres have develpoed splits thru' to the cords in the sidewall close to the wheel rim ( between rim itself and the tyre's rim protector ridge) still have 4 mm tread left and imflated correctly. Anyone had similar problem ?? some splits are on inner wall but most on outer wall.

Sounds like you have either defective tyres that might get replaced under warranty OR illegal counterfeit tyres. Worth contacting Goodyear.

How old are the tyres? They should have a date stamp on the sidewall

I have GY Efficientgrip on the 17" wheels on my v6 Q4 SW.
Been on for 6months and 6.5k miles - no such problems.
Obviously, someting very wrong in your situation....

I ran these on my ex 156 for best part of 50k plus and never had a problem.

Thought I would wake this thread up.
Advisory on MOT so checked today.
Goodyear Efficientgrip on my Alfa 159 (225/50R17 98W)
Radial split on inner wall just above rim for 1/4 of tyre.
13000 miles with 5mm tread left.

Maybe a looming problem.

My first thoughts would be they have been run under inflated but only you can answer that.

I've never run them on my 159 only on my ex 156 and as we know they are very different animals.

The four wheel alignment can only help.

Now this is interesting, both front tyres on my Spider( Efficient Grip 205/50/16)
worn to canvas on inside edge after 3,500 miles. Tracking etc checked and all good. Looks like there might be an issue here.

I think you may have a seperate issue.

How old are your front wishbones?

It is possible that your tracking is fine with the car stationary, but when the car is moving there is enough play in the suspension to scrub the tyres.

Separate issue I think.
Mine were set up with 4 wheel alignment, have no uneven wear, still have about 5mm of tread across the entire tyre, no damage elsewhere, never run low or high on pressure.
There is a moulding line around the rim..it is this on one that has split.

Yep your right. better look at the wishbones I guess, p.d.q.

You don't have the run flat version in error do you?

These tyres get very mixed reviews, one star or five!

Not sure if you have already, but what settings are they using for your set up? The ones from the book, or closer to 0?

Spider

Avon 255/55/17 98Y. Tracking out

Just checked mine on diesel spider and c10000 miles and just ordered new Goodyear eff grip. Maybe I should not have.
I think the issue is more than tyres. I will get suspension and drive checked. Will update next week

From what I gather the standard Effiicient Grips are pretty average. The ones to go for are the newer "Efficient Grip Performance"

Hi

New danish member & just become owner of a 2.4 159 here...

2008 210 BHP 100.000 Km...Mine seems to torque-steer quite a lot (tuned with box), but also seems to wander a bit about under braking....Just wondering if yours do any near the same? (Thinking of bad wishbones could be the reason mine does so & would like to save the tires...& pass M.O.T :-) )

Hello, I don't own a 159, but your problem either sounds like it is tyre pressure related or worn wishbone bushes.

HTH

What's the load rating? Should be 96XL IIRC. I'm betting they're not up to the weight of the car.
