I changed my tires on 26/7/25 and choose compasal tires size 145/70/12 for my mehran car on shop keeper's advice.I feel on return from the shop that car is taking jumps more than before. drive is not comfortable. very little up & down on the road jolts the whole car. I called the shop keeper and explained the pain I felt. He said air pressure may be more in tires, go and check it, I checked it twice from 2 different places it was 30 in all tires, he also said for wheel balancing and wheel alignment, I also went for that but issue didn't resolve. I got very bad experience with these tires and did not recommend it further.
