Top Radar Dimax R8 Review

Given 75% 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 73% while driving a BMW 335d (245/35 R19 W) on a combination of roads for 2,000 average miles

Given 83% while driving a Ford Mondeo Titanium X (235/40 R18 R) on a combination of roads for 10 average miles
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!

Trying to pick the very best winter tyre? Watch this!
Given 41% while driving a Jaguar xf premium luxury (255/35 R20 W) on mostly town for 5,000 average miles
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.
