alright so i have an 06 ls and had some 17's but they were just to small for me so i sold them. I am going to order the progress springs tomorrow that will lower it 1.5" front and 2" rear and i want to step up the rims to either an 18 or 19 and don't know what tire size i need with either of those if i have the drop. and dont know what is better to get 18's or 19's HELP!!!

and also include the width with of the rim ex. 7.5 or 8 with the diameter of the rim please

and the offset.

the bigger the rim, the smaller the tire.

small tires/big rims = possible rim damage, noisy, bumpy ride

i have 17s and want to go with 18s

maybe 19s would be too much unless you like to feel the road

How bout using the stock SS/SC sizes, that way you know it will fit the car. Also tirerack is a great source for all tire and wheel fitment.
