Uhh those wheel specs mean very little. What is the width of the wheel? Offset? You should be posting something like "18x8.5 40mm 225/40/18".

Sorry, The rim is 17 inches with a 9.5 inch offset. The tire width measured out to 9 inches. Do you think 5mm in the front and 15mm in the back would look alright? Who is also a good refferal to order from? Thanks!

offset is the distance from the outside of the wheel to where the hub boots up to it

1. lay the wheel/tire face down on a hard surface...

2. lay a straight edge across the upward facing rim/tire

3. measure from floor to the inside of straight edge (that will give you the overall width of the wheel/tire) (example 10 1/4" or 10.25" )

4. divide that by 2 : 10.25/2=(5.125" or 5 1/8")

5. now measure from the straight edge to the mounting face...(example 6.75" or 6 3/4")

6. subtract the 5.125" (10.25"/2) from the 6.75"=1.625"

7. take the 1.625" x 25.4 (25.4mm=1 inch)

hypothetical answer= 41.275mm... that's the offset...

the wheels should have size and offset stamped on them (inner side)
I would go 5 and 12 if all 4 wheels are the same size
