Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tire tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

Mazda 3 Sport 2.2 Diesel 185 BHP (225/45 R17) on a combination of roads for 10 average miles
Using The Rain sport 2 on my Mazda 3 sport 2.2 185BHP model and have done about 10K with them they are quite a noisy tire but now the rear ones are producing excessive road noise as if a wheel bearings had gone so when I had it serviced I asked that the rear wheel bearings be checked. The outcome was that the inside edges of block treads had worn into a wedge shape causing the tires to bounce. I returned to the tire supplier and they have said it's a suspension problem(Rear shocks)which I find hard to believe as nothing has shown up on the service, the car is a 2010 model and not driven hard. If any one else has experienced the same and knows why this has happened I would love to know. I am now faced with having to buy replacement tires and the worn ones are going to be sent to the manufacturer to be tested. So far very disappointed with these tires, never had a problem like this before with tires. I was also told it may be that these tires just don't suit the Mazda 3!

Given 74% while driving a Volvo V70 D3 (225/50 R17 W) on mostly motorways for 27,000 easy going miles
I had these fitted on the front axle my Mk3 Volvo V70. They still have 2.5mm on them..after 43,000km/27,000 miles. I did notice that the level of grip decreased in the last 10,000 km of their life but I don't really care especially when I look at the average people are getting on these tires. I do mostly highway driving and the V70 is on the heavy side at 1,700 kg curb weight and front wheel drive. I'd buy these again

Swapping from Bridgestones to these tires was like going deaf! We have had this Mazda 3 TS2 for three years on Bridgestones and I can tell you that they were deafening. These tires make it feel and sound like a new car. I can actually hear what the passenger is saying to me now. I don't know yet about wear, but I don't care. I can now drive without the earplugs.

I bought some used wheels and there were two Uniroyal Rainsport 1 tires on them. The other ones are Goodyear Excellence. So obviously I put the Uni on the front of my car.
They have a great dry grip and, as assumed with Uniroyal, fantastic wet grip. But these tires have real soft sidewalls which will make them feel like they want to roll off the rimm. They also tend to screech while cornering.

So I put the Goodyears Excellence on front and that's much better. Equal in dry and wet grip without the downsides.

My conclusion is that the Uniroyal Rainsport tires are nothing to write home about. I would, for sure, never spend money on them. Same with other Uniroyals cause the thing with the soft sidewalls is something that is mentioned frequently.

I found this tires put on the front wheels when i bought my car. I was thinking it drove good until I bought Pirelli Pzero Neros and experienced that it could be better. No screaming tires anymore by cornering and less tire noise by normal driving. And the Pirellis got a better grip.
But I think its still a good tire.

Given 67% while driving a Mazda Mazda 6TS Estate (205/55 R16 V) on a combination of roads for 1,500 average miles
Had to get a full set of tires for my Mazda 6 estate. Looked through various review sites looking for a good grip tire in wet conditions. Chose the Uniroyal Rain Expert. I can not criticise the tires performance in terms of grip. Grip in both wet and dry is brilliant. Very safe tire. I have driven 1500 miles on these since purchasing in November 2011.
I have been driving for over 35 years, in this time I have driven on many different tires, makes, tread pattens, etc.. so I can honestly say the noise is the WORST I have ever had from a tire. My daughters liken it to a pod racer in Star Wars, or the sound you get from the tires of jet landing on a runway.
I did offer Uni Royal via there web site comments link, to listen to the tire on my car and discuss why they do not put a warning about the sound these tires make, but it seems to have fallen of deaf ears.... ! perhaps that is why the do not realise there is a noise problem !

Just awful. Went from an Avon zv3 to these and it is now like driving on pillows. Car wallows and feels unconnected to the road. I guess they are predictable and reasonably comfy and quiet but do not get them on anything you would like to go around bends in.....what a disappointment!

Appalling wear on these tires - havnt lasted 9000 miles yet !. I noticed wear at 2500 miles. Yes - they stick ot the road, wet or dry. They look good too.

I actually thought these were seconds !. Wear is the worst ever. Its back to Avon Z3's for me.

This is a review of the Rainsport 1's on the front of my car, a follow on from my previous review of these on the rear.

I have to say that I have really not been overly impressed by these. You get more feel of how good or a bad a tire is when theyre on the driven wheels and what felt like an alright if a little grip deficient tire on the rear felt completely numb on the front.

Straight line grip in the dry was actually quite good. I didnt find wet grip to be any better or worse than any other tire ive had, so dont get this tire if your sole concern is better grip in the wet. As I have said, the tires feel very numb and made the steering of my car feel overly heavy. One of the biggest things about the st170 is its sublime steering feel, but with these on it was reduced to what i can only describe as steering through sludge, no sharpness or directness. Although there was little feel, the tires progressed into understeer gradually. The main issue I feel is that the sidewalls are incredibly soft, ompared to continential sport contact 1's, pilot sport 1's and my latest rainsport 2's. I can squash the sidewall with my hand incredibly easily with the rainsport 1's. This soft sidewall is totally apparent in any kind of at speed cornering. Going round a large roundabout with the window open, you can physical hear the point where the sidewalls of the tire fold on themselves. At this point you still have some grip, but zero feel.

Wear has been ok, at a total of 24000 miles. Not as good as the Michelin Pilot Sport 1's which lasted 30000. Comfort is excellent, I assume as a result of the soft sidewalls and quite soft compound. Of course, in a 'sport' tire this isnt really what your looking for.

Always run Michlin Pilot Sports on my BMW since I bought it and always had good traction wet and dry with more than just spirited driving and very rarely saw any traction control lights even after I had a DMS remapto 270bhp/410Ibft.
Thought I would see what tires other people rated and saw these rainsports were in the top 3 when my michlin's were rarely in the top 20 so I thought I would give them a try. Must say they were harder to get hold of but they did come in cheap @ ?150 each. I had both rears changed to rainsports and kept the Michlin's on the front as they are only 1/3rd worn. First impressions were not good as the tires had zero grip like most new tires but they also have very soft sidewalls so the car feels like the rear tire's are flat even though they are pumped up to 3 bar. They got better after around 500 miles but they are still struggling to maintain grip. I find when I exit a motorway and the road bends round the DSC flashes on the instrument and I can feel the car automatically braking individual wheels to keep the car from sliding out as the rears can not live with the front grip. I wouldn't mind if I was really pressing on but this happens when driving normally. (depending on what you class as normal I suppose)!
Overall I'm dissapointed with the Unirayal's mainly in the dry but they are no better than the Michlin's in the damp so I think the reviews for these tires have been posted by someone from Unirayal's sales team!
You do pay for what you get I suppose so I'll be back on to Michlin's asap.

bought these to replace the pirellis that i fitted on my car. Infinatly better than pzero rossos. The grip in the dry was fantastic. The grip in the wet made the road feel like it was dry. the ware rate was pretty good as well with one lasting 25k miles on the front of my mondeo zetec s, the other sadly failed in its prime after hitting a 1.5 meter long 8cm deep pothole at 70mph! They have good size rim protectors as well. They were as good as goodyears F1 GSD3s but were cheaper .

This is a review of these tires on the rear of my car.
A good all round performance tire.

Dry grip has been good if not exceptional. If anything the problem is not the rubber itself but the somewhat soft sidewalls which give and make the car slide out under hard cornering. This was shown markedly when driving a very twisty mountain pass in the Peak District where almost every hard corner had the tires sliding a little. This was definitely not a huge issue though and even in this situation the actual grip was still good and very controllable. For normal driving these tires are faultless. I found them quiet and comfortable.

I didnt really find these 'rainsports' any better in the rain than my previous michelin pilot sports, although they did get up to temperature and optimal grip faster.

Wear rate has been good. They started with a thread of 8mm in the centre and 6-7mm on the outsides and have gone down to 7mm centre and 5mm on the edges in the 15000 miles they have been on the rear.

All in all not the ultimate tire but for the money a very good one.

The wet weather king, they also grip/last better in wet and DRY than the eagle f1's that replaced them.
Awsome tire, WARNING though go below around 5/6C and they don't work very well at all, seems to need heat to get good results, so if very cold don't get as much grip which can catch you out.
This apart I would defo use again the original rainsport(1)
