The lower the number you go in size 40, 35, 30, etc... the thinner in profile the tire will be. So a 30 will be thinner of a tire than a 35. If you were to go 19's I would suggest 35 series. Since you are going with a bigger rim I would suggest a thinner profile tire.
I looked up prices on the iForged Evolution rims and they were really expensive. So I think i'm just gonna go with SSR GT3 19" by 9 front and 19" by 10.5 rear with Toyo Proxy T1 275/35ZR19 tires. Thanks for everyone's help.
