I have a citroen Jumpy working van. Got this car brand new in 2016 with factory tires: Michelin Agilis 51, wich i dont find in this website's database. Original size was 215/60-16" with weigt load index 103/105. The tires was crap in every way. Wheelspin on wet road i roundabauts, very loud inside the cabin, torque steer everywhere, and the ride....man the car was falling apart almost. For instance it was not possible to drink coffe without get some on your shirt. I belive it is to blame the very high load index, wich we are strigthly applyed to use by law here in Norway on vans.
Anyway, i chose to get some 18" inch alloys on this car and not care about the load index. A suitable dim i found to be 235/45-18". Almost the same diametre as the old 16" tires. With little money to spare, i chose the cheapest tire i could find in Norway in this size, Hifly 805. 60pounds a piece.
I have now driven the car 600 miles with this setup. (235/45-18 W 98XL) And I am positively surprised! As a cheap tire, i was expecting a lot worse. The car is a lot more stable under acceleration, with less torquesteer. That alone could be the size of the tire. But dry grip are improved by maybe 200%! 130 kph trough some bad norwegian B roads....in a van :p no problem at all. The noise is louder in a different way than the 16". Less rumbling but more sound in speeds over 70 kph. Again, im sure it is to blame wider tires, and a poorly sound insulated 3 seater van.With that said, the sound never gets annoying. The only downside is that the tires can be seeking left an right while you drive. More than axeptable imo. But than again, we have asfalt with deep ruts here in norway. Never smooth, plane road surfaces. And another thong is that the front tires can feel a little bad on feedback. Overall grip is good, but you never know trough the steering wheel really. You just have to push the limits and find out.
Rubber compound are relatively soft, wich gives the good grip. Sidewalls are stiff so in heavy cornering, the car feels stable. I have not got a chance to test it on wet or durability yet. Overall this is a lot tire for the money. Not a top tire in anyway, but ok. And way better than any crap van tires. Next time with a little more money, i will get goodyear ass 2, or hankook s1 evo2. But for now the Hifly 805 are ok! If you have a high performance car or you have high comfort standards on yoyr tires, dont by Hifly. But it will work for plenty of people!
