I've had Falken ZIEX ZE950s on my Mazda 6 and I was very happy with the. They are also affordable.

Bought it brand new in April and the weekend after I took it Joshua Tree and Palm Springs. Felt great. There will be more adventures. At least that's the plan.

Do you have a contact or reference link for these? I am interested in doing this for just a little more clearance for my tires. Thanks!
