After almost 20,000 miles of mixed use I have order another full set of RainExperts. These are not the tyres for you if you are a boy racer and push things to the limit. But if your priorities are safety and comfort in typical British conditions then get these. Even when worn down to 2-3 mm they feel much better in the wet than the Michelin Primacy tyres that were fitted from new. I can only compare these with the Primacy on my car but I would say:
Dry Grip - Primacy slightly better
Wet Grip - RainExpert much better
Feedback - I'm not a boy racer
Progressiveness - I'm not a boy racer
Wear - No difference
Comfort - RainExpert better
Noise - RainExpert quieter (I was surprised by this)
Snow/Slush - RainExpert better (but it's not a winter tyre)
Fuel economy - Primacy perhaps slight more efficient
Buy again - Have done

Fantastic

Great for wet & dry summer use only.
Poor tyre wear. Two front tyres needed replacing after 8k.
Very poor on ice & snow. Avoid for winter use.

Update on tyres to the Vectra post 7 item down. In the end the tyres lasted to 7,325 miles and were finished, the rears still look like new and I am very happy with them. I tried to contact Uniroyal to express my disapointment in the way they wore to no avail...not interested. I changed the fronts to Vredestein Hi Trac 2's, just as grippy and deep treaded but with a higher wear rating of 340 so I will see how these go.

noticed an instant difference compared to what I had previously. I have only done a thousand miles in them so will post again another time.

I bought a set of Rainsports when I moved to the countyside where you often get large puddles and water running off fields etc as well as the roads being narrow and windy. They are excellent. So good in fact that I bought a second set of wheels and put Uniroyal's snow and ice (SP66) version on them for the winter (it usually snows where I live) and they were also very impressive. In my opinion they do what they say on the tin.

Very good grip in the wet, good in the dry, predicable all round. I would like to get more miles out of them. We get lots of rain in the west of Ireland very impressive on the wet country roads here. You will have to push them very hard to lose them.

Without a doubt, the best tyre i have had. It's not for those who drive their car like they stole it, the sidewalls are built for comfort and they deliver just that. Nothing short of awesome in the wet, much better by far than the contis and michelins i used before. They are really hard wearing too, i expected them to wear faster given the grip they provide. These WILL be going on my car again.

The best tyre to buy if you live in the south of England! Will only buy this tyre for England.

Peugeot 206 cc. Showing 3 mm tread left on front tyres after 14,000 miles. So what you gain on the swings you loose on the roundabouts and probably sums up the tyre characteristic for wet driving. ie soft

Rear tyres have Goodyear Eagle NCT 5 fitted and have 7mm tread left after 32,000

As second owner I noticed previous front tyres were Vredstien that lasted 30,000miles!!!

Bought two for the rear of my mx5 after scaring myself too often with the back end throwing itself about in the wet! - since then I have had no further incidents and feel confident going into wet corners - seem to lasting well too - 12,000 & plenty tread left.

I had four fitted to the car a while back, they are as said very good in the rain and very close in the dry considering the tread width which is wide. The ride is also very good and they hold their pressures well. Here it comes...But my fronts have nearly had it they are down to 3mm in just 5,600 mile these are the most wearing tyre I have had to date on the front. I run the fronts 3psi above base pressure because the 65 profile just sits on the tread instead of standing on it, my rears are also 3 psi above base and are like brand new the buy again choice on this site I have rated low but would buy again for the rears.

My car does eat tyres on the front but not to this extreme other 280 treadwear tyres have gone much futher with me in the past I have a pro pressure gauge as well and have had it calibrated so the pressures are accurate. One thing to some of the other reviewers they do not come in 225/45/17 size have you confussed this tyre with the Rainsport tyre.

All in all I really like this tyre but not on the front of my car because of the very high wear rate...my driving style is easy going I am 55 and not heavy on corners or braking some cars they just dont suit on the fronts my Vectra is one.
