Good in dry, very good in wet with very good roadholding and low noise levels. Sidewalls clearly harder than previous tyres RainExpert 3's.

Shocking tires, just had a set of 225/40/18s put on. Side walls are really soft, causing the car to feel like a boat, I upped the PSI to 40 all way round to see if it would help and it’s only made it worse don’t buy!

Having been using this brand for many years on my daily drivers for more better handling in the wet British weather we have. The tyre gives good feedback with good grip in both wet and dry conditions. Wear wise I I am yet to find out as I have only covered around 500 miles but they are similar to the predecessor RS3s. Depending on the car and driving style you should see a lot of use out of these tires.

The best tires I have ever used. Absolutely excellent wet grip control, day grip is very good as well. Rain Sport 5 is not very noisy, for the price is very comfort and have extra handling skills especially in rainy weather. With these tires you feel comfortable and safe at the same time. Generally, this is one of the best mid-range tyre and definitely I recommended to everyone. If you buy it you won't regret it.

Gave the Rainsport 5's a go this weekend at Oulton Park and it just so happens Storm Dennis was in full effect. So glad I did as conditions were horrendous. I was very nervous about going out on track on unknown tyres in my mid-engine MR2. I needn't be though as they were unbelievable. So much better than the Rainsport 3's I'd used previously. Wet grip 11, wet handling 11, wet braking 11. I had to reduce tyre pressures by 10 psi and was getting brake fade with track pads in they produced so much grip/heat. Highly recommended for wet weather driving. See for yourself here on my YouTube channel: https://www.youtube.com/watch?v=9dm8qtcGU_4&t=270s

I have had these fitted to my car for two weeks. I got a good deal on them from Demon Tweaks (with a 20% ebay discount) hence why I decided to go for them, plus I had a good experience with the previous RS3 tyre on another car. These replaced a set of Goodyear Eagle Assymetric 3's so much of my review is going to be based on a comparison to those.
Firstly Dry grip, they seem very good in this respect. I cannot tell any difference between these and the Goodyears.
Wet grip. Aquaplaning resistance is excellent, probably down to the very deep treads. However on wet but not soaking roads they seem to lack traction when pulling away, and I can make the rear of the car step out under throttle which I couldn't do with the Goodyears so I don't think they are all that brilliant in this regard. Especially as the Goodyears were worn.
Road reedback is good, as is handling. They seem nice and predictable on the limit.
I cannot comment on wear as it is too early to say.
Comfort. These are XL tyres and I do find them rather firm over bumps. They are certainly not as compliant as many other tyres I have had. Noise wise they are quiet however.
Would I buy again? It would depend on whether they are on offer or not. I would be tempted to spend a bit more on a set of Goodyear Assymetric 5's as if the Assymetic 3 is anything to go by they will be a better tyre in most aspects and not much more cost. Failing that and if cost really was a factor I would go for the Falken FK510. The wife has them on her car and they are also a better tyre (and cheaper)

Excellent tyre had them on for almost a week, Wet grip when cornering just gets tighter as you turn into it can actually feel the amount of grip, My mondeo ST is on firm springs so comfort is not something thats going to change with a tyre as there low profile anyway. The sidewalls seem alot stiffer compared to the RS3 aswell. Definitely a tyre worth buying by all means.

I paid £90 a corner fully balanced with new valves.

These are new to the market. I got mine from Demon Tweeks. To be honest they have only been on a couple of weeks now but with the recent wet weather in the UK these tyres are awesome. I can honestly say for the price the Uniroyal RS5 is excellent in the wet and very good in the dry. Cannot comment on wear. The noise level is adequate. The sidewalls aren't too soft either. Great feedack also from the tyres during cornering. My car was a nightmare in the wet through twsiting country lanes, but now she feels confident and poised. Very early days but the hype on their wet grip is true.

Having used rainsport 3s for the past 2 years or 42.000km it was time for a change. I always change at 2 year interval October or November with 40-45k kilometres on average. I reside in northern Greece and the last time round I fancied the idea of an all season Tyre but after the fitters recommendation ended up with the uniroyals. The rainsport 3s were a revelation in winter and commendable in the summer. I always fit premium tyres and the rainsport 3s were left wanting a little bit for grip in scorching hot tarmac.
The rainsport 5s in question are on initial impressions (1200km so far) a bona fide premium Tyre in the dry, gone are the days of the soft sidewalls. The Tyre provides excellent turn in and high speed stabillity. In the wet is still king though I have never tried nokians. Don't be fooled reading tests that other premium are equally good in the wet. In deep water and poor road surfaces the uniroyals offer a sense of security above anything else.
They are also less noisy but for some reason maybe unrelated to the tyres the fuel consumption is marginally higher.
Also the experience from the 3s taught me that in very light snow to they are drivable I am not suggesting they are as good as all seasons but they provide some traction and don't have the typical wooden feel of summer tyres.
All things considered a great Tyre.
