Guys i am looking into some 17 inch rims? How will they effect handling/acceleration over stock 16 inch rims?

Also will 17 inch rims with 245/45's on them fit on an fd that is lowered approximatey .75 inches? If not what do i need to do to make them fit...i am a newbie on this..sorry.

thanks!

 

also what does offset mean?

 

The sidewall heights will be similar in size to 245/45-16s, but the overall tire diameter will be larger by an inch. The 17-inch diameter in that tiresize will just add weight, and make more room for larger brake calipers and rotors. Of course they'll look better too

You'll need to dial in some negative camber to tuck the tires underneath the fender lips. Probably maxing the camber out -1.5 to -2.0 degrees if possible will work.

275/40-17 and 245/45-17 for road tire sizes are a bit on the tall side at 25.7 inches in overall tire diameter. It's best to stay within the stock overall tire diameter of 25 inches, (+ or - 0.3 inches)

Road tire sizes that fall within stock ODs are 245/45-16, 225/45-17, 235/45-17, 245/40-17, 255/40-17, 265/40-17, 225/40-18, 245/35-18, 255/35-18, 265/35-18, 285/30-18, and 295/30-18.

 

thanks

 

Good news for you ... 245/45's will fit on your stock 16's. But to answer you question ... bigger wheel = wider tires. Wider tires = more grip. I've read that people feel like the acceleration is slower with the bigger wheels. I'm not sure if that's from adding more unsprung weight or if it's from having to apply more rotational force to spin the wheels. Good physics question ... but not my forte.

Offset is the distance from the hub mounting surface to the centerline of the wheel. Positive offset is where the hub mounting surface is closer to the street side of the wheel. Negative offset is where the hub mounting surface is closer to the brake side of the wheel.

SleepR1 has a plethora of tire widths for 17 x whatever dimensions. Check out some of the other threads on this forum for what has worked for other members.

 

i pmed you sleeperR1..the rim/tire combo is actually
SSR Integral A2's 17"x8" and 17"x9" with 245/40 and 255/40 Toyo T1-S tires.

This does NOT show offset, but imagine a centerline running through the cross section of the wheel in the diagram. The distance between the centerline and the mounting face of the wheel to the hub is the "offset"

It appears, Fikse uses front space and back space only.

 

Depending on the weight and mass distribution of the rim, the increased moment of inertia of the larger (width/radius) wheels has an effect on lowering acceleration quite a bit more than that expected simply by just taking the mass difference between wheels. You will have a decrease in the car's acceleration because of increased roational mass, and hence more rotational energy stored in the wheels for a particular vehicle velocity, and if your overall rim/tire radius is larger you will have another source of less acceleration, which is equivalent to lowering the final drive.
