    I put them on the rear of my 330i and as soon as you go above 65mph the back end becomes twitchy, its almost like they deform to a oval shape and the car shakes left and right, honestly not worth buying!

    Given 100% while driving a BMW 530D M sport (245/45 R19) on a combination of roads for 500 spirited miles
    This is a first for me to buy budget tires.
    I have to say i am very impressed with the grip and the handling and the comfort much better than the Bridgestone they have replaced.
    I don't do reviews but when i was buying these i looked at the reviews and it was a bit mixed, so all i have to say is i have put two tyres on my BMW530d for less than the cost of one from a brand name, and they are brilliant.
    i can't tell you how happy i am with them

    Radar Dimax tyres did well on my super super low 07 Subaru Forester.
    I drive the car hard and they handled well and I used them right up until they were totally bald. Maybe the treadwear could have lasted a bit longer but I'll take that for how well they did. Cheers

    Only do about 4000miles a year. The tyres were brand new when I bought the car I’ve done 12000 miles & thought all was good until yesterday when I got a flat tyre warning - on checking there was a 10 inch rupture on the inside wall of the rear near side . The other is showing signs of cracking on so it’s going to be replaced tomorrow. I certainly wouldn’t have again.

    Given 30% while driving a BMW 320D (225/45 R18) on mostly motorways for 3,000 spirited miles
    BMW 320d GT. changed to these on the two rear tyres, just before a road trip from Ireland to Berlin. Oh dear, these are clearly not suited. The car is twitchy and swimmy at anything over 100kmh. Have to keep two hands on the wheel and concentrate to keep it going in a straight line. It’s almost divergent. Really unnerving. At Autobahn speeds of over 160kmh it’s a real white knuckle ride. Other peeps are clearly having a different and good experience with these but I can say unequivocally that they are not to be used on a 320d GT.

    I put theses tyres on as a cheap alternative and cost effective. They are awful past 50mph in corners and the TC light flickers at the hint of a bend. I am having them removed and replaced for safety concerns. If all you use them for is little town journeys then they'll be fine - do not take on wet motorways!!

    Had these on my 2.5l Turbo Ford Mondeo for last four years, absolutely no issues with them at all; a great, cheap all round tyre. And I have been known to drive in a spirited way sometimes!

    Look good but perform badly. I don't believe the tyres EU ratings whatsoever. The tyres are noisy and wet grip levels do not reflect a B rating.

    Mercedes Benz (255/30 R19 W) on mostly motorways for 25,000 average miles
    Bought my E class a year ago. The dealer fitted these new so I expected them to be budget tyres. Normally I fit Conti 5s to my Mercs. So far the main plus is the wear. I've done 25000 since buying the car, mainly motorways, and I still have 5mm easy all round. The fronts generally last forever anyway but even on the rear, I can get another 6 months out of these tyres. For anyone who does high mileage, that's a real heads up. I think road noise is higher but performance is fine; I don't drive in the limit. I probably wouldn't choose these tyres bit I cannot really fault them.

    Bought these Radar R8 runflat Tyres for my 7 Series
    They are half the price of Goodyear/Pirelli and last at least 90%
    As long.
    As I do huge mileages, it makes sense for me to use these
    They balance nice (with less weight required than Pirelli)
    Also are very quiet, and so far have done 10k miles and have over
    6-7mm left so fingers crossed will get to 30k miles

    Jaguar (275/45 R20 W) on mostly motorways for 100 average miles
    I went to purchase my usual Landsail tyres that I've had for a number of years and always found them very good value for money but the dealer did not have them and sold me 2 radar tyres for £180.
    4 days and 70miles later my wheels were removed for a refurb and I was amazed the inside of tyre had a bulge all around the inner edge. I had not merged it or anything like that. Went back to the garage who advised that all they could do was fill out a form but radar will claim it's my fault and the claim will be rejected. I changed back to Landsail. If anyone offers you these tyres do not accept them. Awful tyres with awful customer service.

    I have used these run flats on the front of my bmw 120d for about a year and have just bought 2 more for the rear which says it all really. These replaced bridgestones which I have used for about 7 years and were indistinguishable in usage. After about 8k miles the fronts are down to 5.5-6mm which I am quite happy with.
