Hey everyone,

Well Im thinking of getting some 20" rims for my '03 F150 ext cab. The rims I am looking at have the following dimensions:

Bolt Pattern: 5 X 135mm

Size: 20 x 8.5

Offset: +14 mm

Will these fit fairly easily and what kind of offset will put the rims in about the same place as stock (dont want a bunch of paint chips cause the new ones hang out to far). I am also looking at getting the following tires:

Kumho ecsta stx
305/50VR20 or
305/45VR20 or
295/45VR20

Will these fit these rims ok? Any opinions on these tires?

Are there any big disadvantages to going to this size rim? Is the ride negatively affected? With the above series tires will I be very prone to rim damage (I do occasionally go down dirt roads but I've never dinged a rim before)?

I appreciate any and all help as I am fairly ignorant to wheels and tires. Thanks in advance!!!

Oh and here are the rims that I am thinking of getting....did a little photochop to get an idea of what they will look like
