Goodyear EfficientGrip Performance 2 vs Michelin Primacy 4 Plus

In this article we will be looking at independent tyre test data, and real world driver reviews of the Goodyear EfficientGrip Performance 2 and the Michelin Primacy 4 Plus to find out which tyre is best for your own driving.

The good news is that both the Goodyear EfficientGrip Performance 2 and Michelin Primacy 4 Plus are Premium Touring Summer tyres designed to be fitted to Passenger Cars, which means comparing the two tyres is relatively simple.

Both tyres are hugely popular in the market place with drivers, and both have been featured in independent tyre tests.

EfficientGrip-Performance-2 VS Primacy-4-Plus

Test Results

Independent comparison tyre tests are the best source of data to get tyre information from, and the good news is there have been seven tests which compare both tyres directly!

Out of these seven tests:

  • Goodyear EfficientGrip Performance 2 finished ahead of the Michelin Primacy 4 Plus in two of the tests
  • Michelin Primacy 4 Plus finished ahead of the Goodyear EfficientGrip Performance 2 in five of the tests

While it might look like the Michelin Primacy 4 Plus is better than the Goodyear EfficientGrip Performance 2 purely based on the higher number of test wins, tyres are very complicated objects which means where one tyre is better than the other can be more important in real world use.

Let's look at how the two tyres compare across multiple tyre test categories.

Dry Braking

Looking at data from seven tyre tests, the Michelin Primacy 4 Plus was better during six dry braking tests. On average the Michelin Primacy 4 Plus stopped the vehicle in 0.99% less distance than the Goodyear EfficientGrip Performance 2.

Been looking for new set of summer tyres after decided to change my wheels size too, I went from 17” wheels down to 16” and fitted new set of Goodyear efficient grip performance 2, latest model tyres, they were made in week 7 of 2020 and I fitted them in week 8 of 2020, absolutely brand new and fresh rubber. So far so good, traveled around 1000 miles and tyres are excellent, performance, comfort, even though they are smaller size there is no negative performance, corners great, braking in both dry and wet is good, car feels very positive to drive , noise level also good.

Coming from the Civics original tyres Primacy 3 that’s lasted 25Kmls or just over 4 years, I don’t do a lot of miles daily but those Primacy 3 tyres served me well with just the road noise being a little loud at times I liked the dry, wet, handling and comfort of these Michelin’s.

So with not a lot of info on the new Primacy 4Plus and needing 4tyres I decided to go with these anyway as only £1.oo each dearer than the primacy 4 when I purchased, in for a penny in for a pound, these are the XL reinforced version I went for as they are a whole 1DB quieter than the non XL version...

Conclusion

In conclusion the Goodyear EfficientGrip Performance 2 performed better in dry handling [s], subj. dry handling, wet braking - concrete, wet handling [s], curved aquaplaning, tyre weight, wear, value, rolling resistance and fuel consumption, while the Michelin Primacy 4 Plus performed better in dry braking, dry handling [km/h], wet braking, wet handling [km/h], wet circle, straight aqua, price and abrasion.

Interestingly, both tyres performed equally well in subj. wet handling and noise, showing that they are closely matched in these areas.

Which tyre is best for you depends a lot on your driving style and situation, plus what you want from the tyre. Comparing all the data in the tyre reviews database, on balance Goodyear EfficientGrip Performance 2 seems to be the best tyre overall.

However, it's important to note that both tyres have their strengths.

Remember, the best tyre for you might depend on which of these factors are most important for your specific driving needs and conditions.

Similar Comparisons

Looking for more tyre comparisons? Here are other direct comparisons involving these tyres:


Footnote

This page has been developed using tyre industry testing best practices. This means we are only comparing tests which have had both tyres in the same test.

Why is this important? Tyre testing is heavily affected by things like surface grip levels and surface temperature, which means you can only compare values from the same day. During a tyre test external condition changes are calculated into the overall results, but it is not possible to calculate this between tyre tests performed on different days or at different locations.

As a result you will see other tests on Tyre Reviews which feature both the %s and %s, but as they weren't conducted on the same day, the results are not comparable.

Lots of other websites do this sort of tyre comparison, Tyre Reviews doesn't.
