Vauxhall Insignia 1.4T Tires

Bought 2 Rotalla RA03 for the front to replace some Landsail CLV2 that have worn unevenly on the side of the tread. Im not a fast driver and do a mix of town and motorway driving. The difference was like night and day, noticebaly quieter on the road and confident under braking. A month later and I've just had two more fitted to replace the (Landsail) rears (which still had 4mm of tread) and the noise levels have dropped again, should have changed them sooner...

Had these on several cars, seem to be an OEM favourite, but they are terrible tires.

Grip is 'adequate' in the dry, and 'adequate' in the wet, but no better, and to be fair they last for absolutely ages. But that's at the expense of utterly appalling ride comfort (it's like driving on the rims, they have absolutely no give whatsoever and send jarring through the cabin on anything other than billiard-table-smooth roads). They last forever because they must have the hardest compound ever used in a road tire. If longevity is foremost in your mind, more so than safety, comfort and noise, then this is your tire!

They are unbearably noisy, easily the noisiest tires I've ever had the misfortune to be stuck with. Replacing them cut in-cabin noise considerably.

Delighted to get rid of them, in the end replaced rears as well despite 3-4mm left as I just couldn't live with it anymore. Jarring, exhausting, painful ownership experience, never to be repeated.

These replaced two cheap ditch finders and two OEM Bridgestone RE050's on my car when I bought it. Cheap front tires we're awful and Bridgestones were rock hard, noisy and had poor grip.

Fitting four ZZ5's on the car improved noise level in the cabin (massively reduced noise), ride comfort (smoother and more forgiving), handling (more precise and responsive) and gave me a lot more confidence in both wet and dry at speed.

These are great tires, and over 25% cheaper than most premium options that are no better (and often worse)
on grip. Where ZZ5's perhaps don't match as well is fuel efficiency (slightly higher rolling resistance), however grip and ride comfort comes first in my book (both excellent), and I haven't noticed a huge drop in fuel efficiency yet.

Too early to comment on wear, but I usually get at least 25k from fronts and 35k from rears. If I get within 5k miles of those figures I'll be quite happy.
