Emotion CR Kai
95 s14
I just got Tein SS and was thinking about going with Work Emotion CR Kai 17x8 +25 and 17x9 +17......
For tires, if I go 225/45 and 245/40, will these be wide enough......
In other words, how much wider than the rim should the tire be, and what effect does this have? I realize 225 is about 8.85" and 245 is about 9.65"
Any help greatly appreciated

I'm not gonna argue over the rim size, as it seems to be simply a matter of preference, but the tires you suggest for those size rims seem like they would be stretched alot.......
Almost every thread I've read shows tires that are wider by a half inch or inch than the rim....so with the 17x9, why not go at least 235 and at least 245 with the 18x9.5
Again, explaining to me the effect of stretching the tire or having excess would be very helpful

I have the same rims I have 17x8 on front with a 245/45/17 Nitto and 17x9.5 on the back with a 275/40/17 the Fronts rub because the tire is too big so if you went with a 235 you will be ok there is no reason to get huge *** tires for the front. They rub when you hit your max turning radius.

So then 9 inch +17 rear and 8 inch +25 front shouldn't rub...... at least inside
Did calculations.....this adds 4mm inside and about 33mm outside up front
and adds 9 mm inside and 55mm outside in back
shouldn't have problems inside with the new coilovers, might have to roll fenders?

not to try to prove anybody wrong but theres always a tradeoff in everything.
stretched tires; this applies more to AWD and FWD cars but it does affect RWD cars as well, a more square sidewall will give more progressive, gradual and predictable break from traction which can be easier to control to an extent.
"slamming" your car lowers your center of gravity, but it will raise your roll center since our cars have the macpherson strut front suspension (not sure about S14s), which will make the roll couple larger and you will have more bump-steer (as well as other things, and generally putting more stress on supension components), which will negatively affect your handling, cancelling out the benefits of the lower center of gravity,
theres a lot of things you can do to help make the roll couple smaller, reduce bump steer and cure many of the problems associated with over lowering your car but its late and im tired so i wont bore you with other little details (do a little research) www.splparts.com .
negative camber will give you a larger contact patch when cornering at the place it matters most, the outside tires, but excessive camber will make your car feel darty when going strait, but of course everything is a tradeoff so you can find the balance that suits you. also remeber that accelerating 1.5 pounds of wheel (and 2 pounds of tire) is the equivelant to accelerating 1 pound of chassis
This should give you a good base to do a little research and help you decide how big of a wheel and tire size you want.

All these suggestions seem to be for extremely stretched tires....
My original question was for someone to explain the effect of using stretched or wide tires relative to the rim, i.e.e how it effects performance, wear, traction, etc.
I mean some of you suggest like 215 on a 17x9 and other sources would suggest 245,255, or even 265
