Bought these to replace 2 of my tires and they look a little too short and might be out of the 4% difference allowed for my awd. They are federal ss-595. Brand new never mounted. I paid 180 shipped. Yours for 150 ---

Thanks GLWS Current size is 225/40-18 I know federals run wide so I got 215’s. after holding them next to each other they look much shorter than my current tires. Haldex says their system will function normally as long as the rolling diameter is within 4% I’m going to measure them later and try to calculate the percent difference. But based on looks they are too small. My mistake someone’s gain
