I'm sorry for doing this but I searched and belive I am correct but just wanted to confirm before I spend $1,000 for the wrong tires.

I have 19x9 +26 F and 19 x 10.5 +22 R and was going to get 255/35-19 F and 275/35/19 R for the tires. Are these the correct profiles tires for the wheels?
I used the ratio calculator and believe these will work with VDC? Is my understanding correct (under 2.7%)? Thank you and sorry for a thread like this.

 

Those are good sizes you should be fine. There may be alittle stretch with 275 on a 10.5'' rims though.

 

thank you, so do you think if I go with a 285 in the rear the VDC will still be okay?

 

I'm sure VCD would be OK with the 285/35 since it's only a .28 difference from the 275/35.

 

255/35-19 F and 275/35/19 R

This is a good match. A 275 mm tire will fit a 9.5 inch wheel. Why pick a 10.5 inch wheel and stick with the same tire?

 

285/35 is a great match for the rear of a z

 

But does 285 work with VDC?

 

emperor answer your question already.
