Top Radar Dimax R8 Review

Given 75% (breakdown) while driving a Volvo V70 2.5 T awd (225/45 R17 W) on a combination of roads for 800 spirited miles
Got these after Michelin Primacy 225/45 17W. Radar is cheap, comfort and quiet. Havent drive much with these so dont know about how long these will last but so far just positive feelings. There was MUCH more tramling when driving Michelins. Sure, Michelins were worn tyres and Y speed but anyway: car was tramling quite baddly with Mich´s but no tramling at all with Radars.

I havent got any problems with grip in any conditions, not even in cold, rainy conditions. In wet road conditions i could keep same speed in hard turns than i drove those curves with Michelin.

Volvo aint a sport car so i dont drive it at the limit but the limit comes via car, not via tyres in this case.

I give "thumbs up" for Radar.

Given 77% (breakdown) while driving a BMW 120d (205/50 R17 N) on for 8,000 average miles
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.

Given 38% (breakdown) while driving a BMW 520d M Sport (245/40 R19 W) on mostly town for 2,000 average miles
started off really positive. Grip and traction was not too far off the previous Michelin Primacy HP that were fitted on as standard. The tyre noise was slightly elevated to the Primacy, however after 2 months the tyre roar became a joke! it was ok around town but get past 40mph and on up to motorway speeds it became an all consuming torture! it sounded like my tyres were rubbing on the arches - would avoid these like the plague. you get what you pay for. coming off after 2 months and fitting the Michelin back on again. The manufacturers put them on for a reason.

Given 34% (breakdown) while driving a Mercedes Benz CLK 320 CDI (225/45 R17) on a combination of roads for 1,500 average miles
Bought a Mercedes CLK 320 CDI with these fitted to the rears and can honestly say they are the worst tyre in the wet andem with a not much better in the dry. Replaced them with a pair of Michelin PS4. I can't imagine why people think cheap tyres a good economy.

Given 63% (breakdown) while driving a Ford Falcon xr6 (245/30 R20) on a combination of roads for 5,000 spirited miles
Bought these tyres just as a cheap alternative for my XR6 Falcon, the car is only driven maybe once a week as I have a company car. For the price compared to major name brand tyres, I am loving them! They handle well in dry conditions, they're not noisy, as with all cheaper tyres if you put your foot to the floor in the wet they spin (kind of expect that with most tyres!).

Overall they are great value for money if you don't want to spend big $$$$ on name brand tyres.
