    Given 79% while driving a Jeep (265/50 R20) on mostly motorways for 25,000 average miles
    Bought these tires May 2021 for my Jeep Grand Cherokee did 38,000 km on on them, it’s now Dec 2023. Really quite tire, ideal for those long hwy trips, grip, towing and handling were fine, no complaints, dirt gravel roads they were predictable in corners. I would have bought again if I could have got them. Great value for the money. I am interested to see if the Maxis HPM3’s will be as quiet.

    Given 81% while driving a Volvo S60 D5 R Design (235/40 R19) on a combination of roads for 10,000 average miles
    Bought 4 of these for S60 D4 VOLVO.All in under £200 just over a year ago.
    They replaced used set of PZEROs that were on there. And I tell you what, I cant spot the difference.....

    Wet and dry handling is just as good. Never felt scared of as if they are going to give way or break away.
    Wear also looks good for a 10,000m after a year.

    Only one problem was the front nearside developed a puncture in the sidewall which was the only downside to these.

    Brand snobbery has gone a long way.

    Got these tires new when I bought my car. After barely 20,000km, there was absolutely no tread left on my rear tires (I've got the pictures to prove it). I use my car for commuting, mostly highway. This is absolutely the worst tire I've ever seen when it comes to wear, stay away from it !!

    Given 77% while driving a Toyota Avensis estate 1.8 petrol (215/55 R17) on a combination of roads for 1,900 average miles
    For information, I am an experienced driver who drives according to the conditions, and can drive a bit over the speed limit if the roads and conditions are good. I have driven about 3000 km(1900miles) and am very satisfied. I have driven in torrential rain and not noticed any aquaplaning (max speed 80 km/h). The tires make a little more noise than previous tires I've had, but not disturbing to me. The sound from the tires was almost annoying at first, but after driving 1000-1500 km, the sound became weaker. I measured the tread depth when they were new, 8 mm. After driving about 3000 km, they are almost 7 mm (6.8 mm). I am very happy with that. Before i have Nexen Nblue HD Plus, and they were very quiet, but after about 7-8000 km there was only about 3.5 mm tread depth. Based on the fact that they are very cheap tires, I must say I am very satisfied! Drives only on asphalt roads.

    Given 10% while driving a Mercedes Benz CL500 (275/40 R19) on a combination of roads for 1,000 average miles
    Tires installed on rear were very unstable and would not track well in the rear. The car was wobbling and un-safe. The mercedes shop could not find anything wrong with the car after 3 hours of checking and test driving. And looking for suspension or steering issues. It was recommended that i change the tires to see what happens . Had to finally replace the tires with P-Zeros which instantly changed the behavior of the car and made it stable as before the The Radar R8plus Very very disappointed - these do not work for luxury performance cars. I checked and others have had similar experiences on A7. I would never buy again. I am returning them and hope they don't give me the runaround.

    Do not recommend these tires if you are looking for high mileage usage. My Radar Dimax R8 tires only lasted 14K and started coming a part on the inside, couldn't believe it until they were taken off the vehicle for rebalance, because of bad vibration and discovered tire was coming apart.

    I have purchased these tires one year ago and did over 13000 miles on them. I can now say they are in the mid of their life. I purchased two sizes: 245/40/20 front and 275/35/20 rear. I am very satisfied with them in any weather condition. I feel safe with them. I am not a slow driver- I'm a dynamic driver. I can recommend them with my honest opinion. Negatives - not so deep rim protection.

    Given 62% while driving a Volkswagen Touareg (225/45 R19 W) on a combination of roads for 3 average miles
    So I just had all four tires (Bridgestone Dueler HP Sport) changed and I went with budget Radar Dimax R8+(DOT 1619). This is an initial review of their performance which mind you is based on a 2.5 mile drive in the wet. Dry Grip: Can't write on this yet as I am yet to drive in the dry. Wet Grip: I was actually impressed by the grip in the wet - they seemed to respond quicker with about same stopping distance to my previous tires which were rated C for wet (and down to 1.3mm trea depth). Road Feedback: was definitely milder compared to my previous, bumps didn't get feel as crude as before (maybe the "well-inflatedness" of the new ones factored into this). Handling: There was a certain sponginess to how they felt,accelerating seemed a little laggy but taking corners felt slightly better and there was no skidding. Wear: can't say much on ths as they are brand new - came with full 7mm tread depth, I'll see how wear goes - fingers crossed. Comfort: I usually drive with suspension set to comfort(else the mrs throws-up everywhere) but I did feel a slight but noticeable increase in comfort level. Buy again: Only time will tell! Looks: I like the tread pattern - with the reassuring 4 main groves present, not a big-fan of the checquered finish on the sidewall and they look a little pale too (will have to get them darkened somehow). Conclusion: So far so good, I have an eighty-mile roundtrip coming up, hopefully that will give more positive insight.

    Given 77% while driving a Audi A6 2.0 TDIe C6 model (245/40 R18 W) on a combination of roads for 37,000 average miles
    OK guys I don't normally do reviews but maybe it will help someone. I got 4 of Dimax r8+ put on my car 27 months ago just before I went for a long trip from UK to Eastern Europe, 3 weeks = 3500 miles. On my return to the UK there was a storm in Germany rain was pouring and we didn't have any spare time to stop and wait otherwise we would have missed our ferry and even in the heavy rain at the motorway limit speeds these tires performed extremely well. In the dry no issues at all. I covered 37000 miles in 27 months and fronts have just over 2 mm left (ready for new ones), rear ones got about 4.5mm left. The tires noise is average not too noisy but not very quiet ether, when it comes to rate the noise it also depends what car in mine average noise is present at low speeds with the windows down, but for the tires ratings I would say the noise is acceptable. I had softer tires before slightly more expensive on a different car that performed really well and very quite but only lasted for about 20k. I do recommend these because they will not break the bank and they do good mileage.

    These are great tires. Can’t believe how little I paid for these compared to “premium” brands.
    I genuinely can’t find fault with them.

    Given 18% while driving a BMW 520d M Sport (275/35 R20 W) on mostly motorways for 600 average miles
    Done 600 miles in these tires so far and they scare the heck out of me. The car is now unpredictable and the handling is scary to say the least. would never under any circumstances buy these again even for half the price. Probably OK for Town driving up to about 40 MPH but above that and they seem in conflict to the car and its suspension settings (Main Dealer Serviced 3 year old BMW). The last time I had Tires that handled this badly was with Cross Ply's back in the late 1970's. In terms of experience I have driven over a million miles in all sorts of vehicles in all weathers and conditions all over the world from old bangers to brand new Beemers and Mercs and these tires are unlike anything I have ever experienced. I have no idea how long they will last but I hope they wear out quickly because at the moment I am considering writing them off and putting it down to experience and buying something safer albeit more expensive.

    These tires constantly change shape as they warm up and cool down with speed changes. The vibration in the steering and noise when this happens is quite bad, though it goes away with more time driving. These tires are probably fine for low speed town driving, as this problem occurs when transitioning between motorway/freeway speeds and town speeds.
