hi. i'm looking to upgrade my g with some new rims and tires. i'm leaning towards the avon tech m550 and professor sp1 from tirerack. my second choice is moving up to 19 but i'd have to get the michelon pilot instead (at double the price).

anyway, where can i take all this to have it put on my g?

second question: do i go 19? this is my daily driver so i want performance all-seasons.

thanks for your help.
