We're fitted on the car at purchase. Kept them on for a good while considering they were also dated 2015. Eventually changed them for kumho ps71s with 2.5mm remaining. With their poor rating in mind I never really pushed the car much with them on, especially in the wet. I found they could plain a little around 80km, after a heavy shower of rain, not something the kumhos are prone to.

The most recent reviews, in their own words
These came on my Lexus IS220d when bought used and i was sceptical as i don't buy tires ever
However they were brand new and i thought i'd see how i got on with them
I have to say i have no real complaints, the dry grip, handling and wear are good. I have had traction control in the wet when you use heavy throttle even in a straight line but if you are smooth then no issue
I use the car on the motorway and its rock steady with a little tire noise, but i think this would be much worse if it wasnt a Lexus ie quiet
Overall surprised, likely would but something better when they needed it but have to be considered on this performance
Only driven on for 150 miles roughly. Had numerous issues spinning them up trying to moderately set off from junctions and understeer coming off roundabouts at 20mph.
Shouldn't be sold whatsoever. It's not like I'm driving a bloody sportscar, it's a 95hp hatchback!
Had one blow out after hard cornering. I replaced the lot cant trust Chinese junk
Got to say these are the worst tires I have ever had in 43 years of driving. They do have some comedy value though, they make me laugh as they massively understeer when there is the slightest hint of moisture on the road. They slide even on modest bends in the dry too. I'm not driving a powerful monster car either, just a small Courier van with 95 HP! They would be good for you if you have too many speeding points though, because you simply cannot drive too rapidly with these on, well not if you value your time on this Planet. Only plus point is their longevity, they just don't appear to be wearing down, amazing really when they spend so much time slipping over jagged tarmac. So the next time my Garage phone me and say "shall I just fit you some budgets on it" I shall tell him where to insert his tires!
Car was fitted with Goodyear Grand prix S, which were utterly useless in dry and wet conditions. These tires handle much better in dry and wet conditions; oodles of grip in the wet.
