Tyres (17")

Wed Feb 27, 2019 10:17 pm

I realise that the subject of tyres has been done to death. However, I will soon be needing to replace the non-runflat 225/60x17 * Pirelli Cinturato P7 tyres that my F25 came with. My only quibble with the Pirellis is their performance (or rather, lack of...) in the wet - even when they still had 5mm minimum tread-depth.

Until I bought the F25, my tyre brand of choice had always been Goodyear. They don't do a suitable star-marked tyre. Although, the consensus seems to be that star-marking is a little less of a necessity on an out-of-warranty car with a "square" tyre set-up. So, I could be tempted with Goodyear EfficientGrip SUV.

But I keep looking at Michelin Primacy. And that puts me in a quandry. 3 options....... Y-rated & star-marked Primacy 3, V-rated non-BMW-spec Primacy 3 (likely old stock), or the same in the newer Primacy 4.

Does anyone have any experience of either the Michelins or Goodyears? Or any other tyre recommendations for older/higher-mileage F25s? My only "must-haves" are good wet-grip and low noise - certainly no noisier than the P7s. Runflats are not necessary because I carry a spare + tools & jack.

TIA

Right! Next shot in the dark............

Does anyone have experience of Dunlop SP Sportmaxx TT runflats on the F25? Any idea how they compare to the Pirelli runflats that seem to be the more common (and cheaper) of the two 17" runflat options?

I'm tempted to try a set, but the fuel-efficiency and wet-grip ratings are making me hesitate. I know the ratings aren't the be-all-and-end-all so I'd appreciate some real-world observations before I drop £600+ on tyres and regret it. I've checked tyrereviews.co.uk but I'm not sure I trust some of the comments there either.

For the sake of continuity..............

I finally decided to ditch the Pirellis when they still had a minimum of 3.5mm tread. As above, I've never been happy with them in the wet. :(

After much agonising I decided to go for Avon ZX7s. On paper they have better ratings than all except the Michelin Primacy. In the past when I've used Michelins, I've thought them over-rated - and I didn't want to buy a set and then end-up kicking myself 500 times*.

When I have some thoughts to share about the Avons, I'll post back here.

I've now thought better of fitting an odd tyre. I bought a Stop & Go tyre plugger kit and an inflator.

Avon ZX7 225/60R17 99V first impressions...........

The first thing I checked, when I got home, was the date code. All 4 are 3019, so they were only made 4 weeks ago. :) I've only done about 30 miles on them, but they are a lot quieter than the P7s. They look a bit "balloony" on the 7.5" rims, and I have a feeling that's because the actual tread may be just a tad wider than the P7s. The steering doesn't seem very much different to how it was with the Pirellis, but I think I detected a slight "floatiness" from the rear when cornering - that could be because they aren't scrubbed-in yet, or because the sidewalls aren't as stiff as Pirelli's. If it is the sidewalls, it's not so bad that I can't live with it. I had a lot worse when I made the mistake of putting Uniroyal Rallye 550s on my E30 - they were dreadful "floaters", to the point where I binned them after about 2500 miles.

I will report back after 1000 miles.

Not really, I've not done 600 miles on them yet. Still haven't driven far enough on them in the wet to comment on wet grip. Other than that, my thoughts are the same as above. Quite happy with them so far. :) I think the "floatiness" I mentioned was just because they weren't scrubbed-in.
