Just put 15's on my car and the tyres look massive. What size tyre would be best?? What profile would be ok on 15's?

Thanks

it's not acutally 45mm

it's the profile ratio, the side wall is in fact 45% of the width, so its 8.775cm

195/45/15 looks nice on 15"

my 15's with toyo proxes t1-r 195/45/15 (see pict)

when your 15's have the right offset (ET49 or close to that) u could us 50 instead of 45 but i'd keep it to a nice thin piece of rubber

but more important, how wide are the 15's ?

mine are 7Jott (7x15 ET35) on wheels with 8 or 9 Jott a 195 tyre will be pretty shitty..

this is wot j1400 told me:

Its ture the lower the better, to a point though.

"This is important in as much that, in order to get maximum grip from a tyre, you must have a load that will "hold" it on to the surface up to and over the point where the rubber compound is incapable of resisting the shear forces acting upon it. Inflation pressure is one way that handling characteristics can be changed quite dramatically particularly as it not only effects the point loading and contact patch shape stability but also influences side wall stability and the resistance to sudden breakaway"

(taken from http://www.novaload.net/forums/article.php?t=63468)

Now the point being made is less tire deflection is good. and a lower side wall causes less deformation of the sidewall, but when it gets too low, it doesn't flex and will just "let go" more suddenly, give very unprogressive handling. a 50 is a better compramise between lateral G's before slippage and feeling when it will happen.
This is further backed up as competition rubber for 15" rims (for cars like ours) is normally 50 sidewall.

I'm not saying that 45's are bad, but if your'e after the pursut of cornering faster 50's are the better choice.

But for asthetics 45's are good, but who can seem then when you shoot past eh
