Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Turanza ER300
Pros
- Exceptional tread life and longevity
- Reliable dry and wet grip when relatively new
- Stable, predictable highway handling and straight-line tracking
Cons
- High road noise and noticeable tire roar, especially on coarser asphalt
- Firm, sometimes harsh ride quality with stiff sidewalls
- Deterioration of wet grip and increased ABS/TCS activation as the tread wears down
Tire B EfficientGrip
Pros
- Exceptionally quiet and smooth ride quality
- Good fuel economy and rolling resistance
- Reliable wet and dry grip for everyday driving
Cons
- Soft sidewalls result in a mushy or 'jelly-like' steering feel during cornering
- Vulnerability to sidewall damage, bulges, and punctures from road hazards
- Faster-than-expected tread wear for some users
What real owners are saying
From Reddit, forums and review threads. Not part of our score
Tire A
Bridgestone Turanza ER300
We haven't collected enough community discussion about this tire yet.
Tire B
Mixed
Goodyear EfficientGrip
Community opinion on the Goodyear EfficientGrip is mixed. It's often recommended as a comfortable, quiet, good-value summer or grand-touring tyre, and some owners report long life, such as 54k on one set. Others criticise it as twitchy and low on grip in the wet on the OEM SUV version, soft and vague in handling on the Performance 2, and prone to sidewall damage, cracking, chipping and slow leaks.

“Ultra contact is average, never tried e-primacy but currently on primacy 5 and they aren't worth the price . My brother drives on Goodyear efficient grip performance 2 currently, and they are way better than ultra contact ( he used them last year, and better than my michelin), so honestly it would be a no brainer to go with Goodyear for me. BUT since you're driving a mazda 3, can't you find continental premium contact in this size ? They are really GOOD, I had them last year, you always have good grip, dry/wet, doesn't matter, that tire is very alive in corner, it enjoys being pushed in corners, only downside is that they wear faster than Goodyear, but I say it's well worth it.”

“How bad is this? Should I replace these Goodyear efficient grips? Apparent tread chipping. DOT 2021, Made in 🇩🇪. Run 30k kilometres(18,000 miles). Mild off-roading on some back roads. Has seen 2 summers in Dubai. Chipping only in front 2 tyres. Diligently rotated tyres every 10k kms. Please advice …..”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
