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

40's do feel rough, take it from me. I had 45's before, much better. 40's do look good if dropped low enough. Coomer has some good info up there. You'd only see a difference between series in terms of a taller side wall. Even if you have the same series, the first number will also determine the height of the side wall because it is in ratio to.
