These tires were a big mistake. Almost immediately the steering response deteriorated and the car, a 2001Mondeo,wandered. Within 6 months it sounded as if a front wheel bearing had failed, so I replaced it, to no avail. The droning persisted! I ran these tires for 13000miles,when the road noise had become very noticeable.Even passengers with no mechanical knowledge would comment. Some 6 weeks ago I spoke to the man in charge of the tire depot I use and commented about the noise etc. He ran his hand round the tread and pointed out the unevenness.
The tread had gone like saw teeth ( like the old threepenny bit). He said he had so many complaints about Goodyears and particularly Efficietgrip that he would not fit them unless the customer insisted. He claimed the tread wear was due to the steel belt not supporting the full width of the tread, that it was a 'soft tire'.
I have now removed these dreadful tires and replaced them with Michelin Primacy 3 and I can already feel the difference. The car is much more stable and there is very little road noise.

I bought a set of 4 of these the replace the mismash of worn out tires i had when i bought my new car.

The biggest problem i have with these is that they seem to have very minimal punture proofing and i have in the last year or so changed 3 of them one at a time due to puntures. Plus they seem to be wearing very quickly. I would say with my driving style they will be worn out in 13-14k.
Wet grip is also pretty average.

When these are worn out i won't be buying them again!

my be I got some bad one's but the road noise horrendous.

The greatest tire I have had so far.
I covered over 55000km in Citroen C5 (heavy luxury car) and they still have enough tread for another legal 10-15 k.
They have good grip overall and excellent stability for side wind etc
Highly recommended !!

These tires are excellent. The grip is very good in dry and excellent in wet roads. The traction control seems to be unnecessary. They are a lot more comfortable than the previous Continental PremiumContacts that I had on the same car. The grip is similar if not better. They wear very slowly and currently after 30000miles, they have still thread for at least 10000 more. Excellent choice.

The latest edition of Goodyear Efficient Grip Run Flat tires give a much better ride compared to the very hard ride of the original GY EG RFs fitted to my BMW X1. I just hope they give the same mileage.

Came fitted as standard on my vehicle from factory. Generally its a good tire. Grips well in dry and wet conditions. Has a quiet and comfortable ride and wears evenly. Fuel consumption is good when running these tires especially over long distance.
Its more of a tire for lwb motorway cruisers and chauffeurs than your hot hatch racer. Its well composed with good road manners and stopping distance is good to excellent.
The only reason I would not buy again is the price. For my style of driving and cruising I find a mid range tire like kumho does just as well but at a cheaper cost.

A good tire should have good grip first then work as advertised. Its one hell of a noisy tire with poor feedback.

the only good (or not so good) thing about this tire is that it will last forever! 40,000 miles and still well within the allowable range.

They should be called 'inefficient grip'.
My tire supplier fitted these in place of the Goodyear Excellence tires which I had been really happy with.
Whilst the grip levels in the dry were OK, in the wet they were dreadful - constant wheelspin when trying to pull away and no confidence when cornering.
There was also no improvement in fuel economy.
I definitely wouldn't recommend them, or buy them again.

Bought these after reading reviews. Cant fault the dry or wet grip. Not a sporty tire.
Biggest disappointment is the noise, supposed to be quiet but noise on all but the smoothest surfaces is terrible like a rumbling wheel bearing noise. Perhaps this tire doesnt suit my car, I dont know, but would not buy again. Hope they wear out quickly so I can get some different ones!

I have had 6 Efficient Grip and 2 Efficient Grip Performance in Total on my 55 plate Passat 1.9 TDIi. They are very quiet, have reasonable road holding, but not at extremes. They do give good consumption and better ewra than the OE Contisprts. However I would not recommend them unless you can guarantee never touching anything with the sidewalls, as they are made of cheese or something even softer. The first set developed a bulge in one of the tires after 8K miles, meaning it was not safe and had to be replaced. I then bo
bought another pair when they fronts wore out and had a catastrophic blow out after only 10 days, meaning another £80 quid as Merit Tire says it's down to the manufacturer to say whether there is a fault. Do not buy these tires if you have to drive anywhere with even the slightest of rough conditions, and don't expect any support from Goodyear when they do blow

Fairly good in the dry, I found them quite silent. But the grip is not so good as other premium brands like Continental, and in the wet they are garbage: it is difficult to have a good answer if you need an immediate brake. Not to buy again.
