Got a 2014 FiST that on 1.5 in drop ford performance springs, I don't have any issue with he stock wheel and tire setup which is 17x7 47.5 offset and 205/40/r17 tires, I've got some room to go alittle wider or different offset. I wanna go 16 in rim but wanna stick to the same diameter so the gearing and speed stay close to the same so I would go with maybe a 16x7.5 or 8 and go for a 215-225 tire would I have a prob with fitment or would that be really close, I want a extreme summer tire for auto x and canyon carving. I just wanna know what sizes will keep the same gearing and have good fitment prefer 16 in wheel but will stick with the 17 if availability is an issue, but I want to go a tiny bit wider, what r your suggestions?!
