need little help on tire size. looked tho threads already

[Realbadchevy]

Hey guys,

i no there is like a bazillion treads and its hard to find what i need or i just dont understand..

i just bought a front set of factory 02 z06 speedlines and i need to find out what size i need i have seen a lot on the front ( 245/40/17 ).

i will be buying the rear 18x10.5 soon. now i have been looking around and i have seen a bunch on 295/35 and 305's and what not but what im kinda looking for is something not quite as wide. would a 185/35 work out for what im trying to do or do i need to go more with a 185/40 ect.?

if anyone had any pictures that would help to. i also am trying to not spend a ton of money on tires because my car dosent get driven but maybe 5K a year... inface this year its only been out little over 2k...

thanks for your help.
