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 23% while driving a Vauxhall Nova (225/45 R17 V) on a combination of roads for 100 spirited miles
Cheap dangerous tyres
They are very hard wearing but everything else is bad
Dont fit these tyres to ur car u have being warned

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.

These are the best tyres in the world. Watch now!
Given 93% while driving a BMW 730Ld (275/35 R20 W) on mostly motorways for 10,000 easy going miles
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.
