hey ht quick ? i have a set of ls mesh with 205-50-15 tires and a set of fat fives with 195-50-15 and wanted to swap the 205-50 to the fat fives and the 195-50 to the ls mesh but if i do will i need to get them balance again? or since they are already balance i won't have to. o and how much will it be to switch just the tires over

 

you will have to balance them again. usually if a shop does it, they will balance them for you included in the price of the mounting. the price of the mounting and balancing depends on what the shop charges. in my area, prices range from 5 bucks a wheel/tire, to upwards of 40 bucks for a set.

 

The tires are balanced to the wheel, so yes, as the previous poster said, they will need to get rebalanced. I was recently quoted $15 a tire from America's Tire, so I just took the wheels to school and mounted / balanced them myself.
