E.Primacy tyres worth the extra cost?

Hi gang!

Looking at new tyres for my Niro and wondering if eprimacy are worth the extra £25 over the regular primacy tyres? Economy rating of A vs C.

Also, reinforced seems to be cheaper…is it worth it for the extra noise?

then there’s Goodyear which seems like a middle ground.

what would you pick from these 4?

My Ioniq had it's tyres replaced by ATS. They switched from Primacy 4+ (non-EV) to e.Primacy (without letting me know).

The e.Primacy is not as good as the Primacy 4+ in just about all ways apart from maybe a tiny, tiny bit quieter but that's it's only positive factor. Grip and feel is much better on Primacy 4+. Range loss when moving from OE Michelin Energy Savers to Primacy 4+ was minuscule too.

Plus one i have the e primacy they are wearing well but grip is poor on my Ioniq and lets be honest the Ioniq is not rapid acceleration

I had very similar Goodyears (prob just EfficientGrip) on my previous ICE (2013 3008 diesel) and they did at least 40k miles, >3 years. They never seemed to wear out!! Were still on 3mm when I got rid of the car. Seemed as good as the Michelins that they replaced in terms of noise, grip etc.

The latest flavour of GY Efficient Grip (suffix "2") are a harder wearing version of the earlier tyre - tyre reviews have it comparable for performance with Micehlin Primacy 4/4+.

My ZS EV has the same size tyres though I think I might go Primacy 4+ when the fronts need changed (reckon at 30-35k going by the wear at 21k miles) - OEM is Primacy 3S

If you read the test reports you’ll find that EV specific tyres tend to do terribly in wet-weather braking tests. This is due to the larger tread blocks. Therefore I plan to swap CrossClimates on to my iD4 when the current set expire. I just don’t do any journeys where a few extra miles of range makes the difference between a charging stop or not. My journeys are either super-short or so long a charging stop is required nomatter the tyre.

If you don’t live in the hills or North (and therefore don’t need an all-season) then have a look at PS4s for spectacular dry grip or Primacy4 if you want a great all-rounder with better comfort.

Michelin sell the e.Primacy tyre mainly on its rolling resistance, which, at least in the tests they summarize in footnote 5 of the e.Primacy web page, is definitely better than Primacy 4 and all the competition they admit to testing. They also claim that it's safer than most to run it right to the tread wear indicator, presumably to make up for the lesser tread depth when new. I found the detailed rolling resistance numbers fascinating -- these are rarely published for plebs to read for nothing. Short summary: all tyres are more efficient when part worn then when new; e.Primacy and Goodyear Efficent Grip 2 are similar when worn; e.Primacy beats all comers for efficiency when new. The efficency bands A to E don't show small differences, since each band is about 20% change in rolling resistance.

My take on this is that these are plenty adequate summer tyres in other respects, and noticeably better than most for rolling resistance. Fitted to a much less exciting vehicle than most of the contributors to this thread, I'd only note that they like to be kept at the vehicle's maximum rated tyre pressure. If rolling resistance (energy efficiency) isn't a worry, the don't spend extra for e.Primacy.

I replaced the Dunlop Enasaves on my Leaf with Goodyear Efficient Grips, I’m not sure now if it was the Performance 2 version but I was impressed by the surefootedness and grip. I never noticed any loss in range and the Goodyears were what I describe as a comfortable quiet ride.

When the time comes to replace the tyres on my Ioniq, number 1 on my list will be the Goodyears, although I am impressed by wear rate on the original Michelin Energy Savers. It’s the road noise at motorway speeds that I don’t like, I have also tried to suppress the noise with soundproof deadening materials, but to me it made little difference?

Personally, I feel that a lot of the tyres fitted as original equipment (OE) by EV manufacturers ‘buy’ you longevity and quietness at the expense of wet braking, anti-aquaplaning and softer ride. You can’t have all of these things in one tyre and I’d prefer a bias towards the latter, even if I miss out a little on the former.

I have a LEAF 62 and replaced the stock DUNLOP's about 18 Months ago with MICHELIN PRIMACY 4 + - 215/50R17 - 95W. (Post Edit "PRIMACY 4+")

I did look at the E-PRIMACY but have found that EV specific tyres are made of a very hard compound that gives the low running resistance, this makes a lot of noise on rough and concrete road that comes into the cabin.

Also standard tyres have more give in the side walls which gives a more comfortable ride.

I have been really pleased with the PRIMACY 4's - they give a noticeably quieter ride, a very smooth ride and a very comfortable ride, handling road imperfections really well while preventing leaning whilst tight cornering. The road grip is so much better and sure footed.

I have done 18K miles with the PRIMACY 4's and would estimate 8K - 10K miles left before replacement.

Efficiency wise, they are a tad less efficient than the stock DUNLOP's but it is really not that noticeable.

Unless you need all season tyres I would recommend the PRIMACY 4 and when they need replacing I will be purchasing the same.

Are they the 4 or 4+. The plus symbol is further around the tyre in a little black box (not where you’d expect on the Primacy text).

I've just ordered a set of Goodyear Efficient Grip 2s, 205 60 R16 92H EVR for my Ioniq '38.
Total cost £579.16, includes £15/tyre for fitting/valves etc, delivery to one of their agents in Petersfield to fit.
Bought from mytyres.co.uk, I've used them before & v happy with their choice & prices, also when they sold me a set of winters that didn't fit my Fabia (their error, new model had larger brakes) & they sorted it no probs.

They have 2 92H EVR offerings, 70p/tyre difference, one rated 69dB, the other 70 dB! So I've gone for the quieter one. Same B A rating for Range Wet-grip - really, are these tiny differences significant? Noticeable?

I'll try to estimate my efficiency when I drive 22 miles there on v worn Michelins, and when I return on new rubber!
