I want to finally get new wheels but I have a lot of questions. I've read a lot of the other threads, but still not to sure, so I'll start of with these.

1. Is there some kind of basis for how low the number is suppose to be?
2. Are there any pros or cons between 17 and 18?
3. Will these fit other than tire size, can i just put these right on
Bolt pattern: 5x114.3
Size : 18x8 Front & 18x9.5 Rear
Offset : 48mm Front & 48mm Rear

 

How low the number is suppose to be for the offset that is.

 

For the front:
6.5

 

48mm is kinda low for a 9.5" rear, i'd say at least 55mm

18s cons = more expensive tires, thinner sidewall means it is more prone to damage if you hit a pot hole, most of the time its heavier than 17s

 

Not really sure what you mean by kinda low. And as far as weight, how heavy is to heavy. The wheels I was looking at I think was like 26lbs in rear, dont remember off top of head for the front.
