first off yes i have read the vdc sticky and top 100 questions and i know if your rear tires are bigger than your fronts by over so much it will cause the vdc to engage i just dont know how much that difference is or how to calculate it but i am looking to put 275/35/19 up front and 295/35/19 out back would this combo make the vdc stay on or should i go with a different setup

 

Its easy to figure out. The difference in circumference is 43.98/2120.89 mm or 2.0 percent. I would prefer to see 3.0 percent.

 

That combo is fine. Speedo will be a little off - davidv can tell you exactly how much.

 

ok thanks the only reason im not going with a 305 out back is that the bfgoodrich gforce kdw isnt made any wider than 295 for 19 inch wheels

my other choice was hankook ventus 12 evo 275/35/19 and 305/30/19

 

Front tire is taller than rear.

 

Do they offer a 275/30-19 for the front?

 

the only kdw for 19" with the 30 ratio is a 265/30/19

 

That would work, or 255/35 with the 305 rear. I'd prob stick to 275/295 though.

 

yeah i think thats what im going to do? where is the best place to buy wheels and tires online?
