40 series vs 45 Series Options

[Davesceli]

Well i need to buy some new tires and i can't decide btwn the 40series and the 45 series. The guy at the shop told me he won't sell me 45 series cuz my car's recommened size is w/ the 40.

I've had 45 and i like em, hows do the 40's compare in ride and performance. the dude told me that the 40 is a wider tire due to the smaller sidewall. T or F???

Since were on the subject...anyone ever try Kumho Ecsta SPT's before. I've read some good reviews on em. i might get those instead of the usual toyo proxes fz4.

thanks

im looking to buy some new rims, cause my 16's with my car lowered and a now new body kit on is a little low (many speed bumps are higher than i am), i know i can go 17, but i was kinda thinking of going 225/45/18 is that to big? does anyone have pics of tires that big?

i basically want to gain that extra inch of clearance to the ground by having a bigger wheel and fill the gap in the wheel well.

any suggestions?
