The Dimax R8+ is also suitable for EVs, with EV compatible size variants featuring a special low rolling resistance compound.

They do exactly what I expected from the rating which was A rated in the rain and from the reviews from other customers. I am really pleased with this budget tyres and they were a lot cheaper than the premium ones so I can get two lots of four for the price of one set of four premium brand tyres.

13,000 miles and they'll need replacing soon. Wouldn't recommend them for wear. Grip in wet and dry is good
