People must be tire of myu questions, but once again i just want to know what would be the difference between a set of wheels being: 19" x 8.5 F - 19" x 9.5 R and
19" x 9 F - 19" x 10 R

 

Wider wheels accomodate wider tires. The amount of tire touching the road is called the 'contact patch'. Generally speaking, the larger/wider the contact patch the better grip your vehicle will get and that's good.

Go wide if you can afford it.

 

they told me the price was the same, i dont know if the guy was lying or something, he told me that after 8.5" the prices were the same.

 

Well, that's great news . . . although even if the wheels are the same cost from 8 to 9 to 10" in width keep in mind that wider rubber costs more.

I have 245x35X19 in front - tires are $215 each. (8.5" wheel)

In back I have 275X30X19 - tires are $265 each. (9.5" wheel)

 

i think thoser are the same wheels i should be getting eventhough some people in this forum todm be to keep the profile the same since, the diameter change in the rear would throw off the TCS OR VCD.
