The tires were fitted at the front of FWD car all the time. The grip level was very good in dry and wet, the drive was quiet and with comfortable ride on mostly motorway journeys all year round. The distinct advantage in comparison to other tires was the hard wearing, long lasting quality - 52k miles.

I had 2 AVON ZV3's and 2 Conti Sport Contact's on my Almera 1.6 SRi which I threw around. Replaced with 4 ER300's when worn out, same great grip but less noise and great wear. Sold the car after 20000 miles on these with 5mm all round (swapped front to back after about 12000). Now have them on my Mondeo MK3 2001 2.O Diesel. Wore a pair put after 21000 (15000 on the front and 6000 on the back on A & B roads and have replaced all 4 tires with ER300's as the Michelin pair I had are cracked and worn also. Paid £70 per tire with a voucher off the web, excellent tires. Would buy again and have recommended to friends. Not quite as long lasting as all beating Energy's, but great grip and £25 - £35 cheaper. The only let down - there is always one - They were crap in the snow on the Almera and the Mondeo.

These tires were fitted as standard to my vauxhall astra that I have owned from new. They have provided very good grip and gave a comfortable ride. The front tires lasted for 30000 miles and the rear tires are still on the car at 4 years and 90000 miles. They are now down to about 2 mm tread and will be replaced soon

I'm a recently new P plater and I got these tires on my Toyota corolla 03. I don't have extensive tire knowledge but these ER300's are pretty good, the car handles really well with them on, they don't slip in torrential rain, quiet and they give a smooth ride.
overall very happy with these tires, would defiantly consider buying these again (:

Have over 46,500kms/29,000miles on these (they were o.e. fitment on the car from new) and still happy with what is a good average tire from one of the best tire manufacturers on the planet.
They have had to put up with being driven on poorly surfaced roads, stoney & gravel tracks etc and haven't given any of the problems in this environment that cheaper branded tires are apt to do.

Sidewalls are soft and cornering stability was poor from day one.
Good grip under heavy acceleration.
Very good grip in wet roads.

Although they seem to last long (visually) they dont. The tire got very slippery after a 10k miles, both on dry and wet roads. The ESP and ABS working overtime.

Pretty noise tire.

I would definitely NOT buy these again.

Front pair did 23000 mainly motorway miles in VW Passat TDi Estate. Still got 1-2mm of tread left although changed the pair due to a puncture in one of them. This is comparable or a better wear rate than Michelin's previously used. Have brought again.

I still have the original set of ER300's / 205 / 60R16 92 V on my 2009 Mazda 6. I've reached 93,000 km. Most of my driving is long distance Riyadh-Dammam-Riyadh in Saudi Arabia under very hot driving conditions and sometimes (when the roads are empty) at speeds of 210 kmh. Very impressed with the log wear and reliability of these tires. I'll be changing them in August when Bridgestone get new stock in Riyadh and I've decided to reduce my speeds until then: but these tires still have ample tread left on them.

Has done only 18650 miles and it is ready to be replaced.
Noticable wear when usage was under 5000 miles.
Regularly rotated the tires, checked and maintained tire pressure every week
Noisy while driving no where as good as Bridgestone ER592 on my other car
Easily punctures, maybe due to the soft compound.
Not happy with these tires. I dont know why I bought them.

Sporty and very grippy but uncomfortably hard/very harsh on rough & bumpy roads but otherwise smooth. (Honda Civic 1.8 with 16" alloy wheels)

38,700 miles on the front and the rears are still ok (40K+?) - quite reasonable by British standards (BUT to put it in context, I bought Yokohama tires for a Honda Accord in the USA that were guaranteed for 70K+ miles and which still looked like new after 50K - they were great in every way: quiet, sticky, good in dry, wet & snow, smooth - and cheap).

I drive around 35,000 miles per annum so insist on decent tires; this is mainly motorway and dual carriageway driving. The old ER30 tires were on my Vectra when I bought it and have progressed onto the ER300s. Very good tires, cannot fault them. I find them quiet and I feel secure on the road. I am getting around 45,000 miles out of a set which isn't bad. It is usually only me in the car but I am often times carrying a lot of stuff. When I swap back from my winter tires (Pirelli Sottozeros) I put fronts to back and get more miles out of them.

Fine in wet and dry condtions and understandably not very good in very cold conditions.

covered 35k with thm from new mostly on motorway. pretty quit. good grip. definitely buy again
