i plan on getting some new tires tomorrow for everyday driving. My question is do i want bigger wider tires in the back than front, or can i get say a 255/50/17 for all 4 and be okay? just looking for a little better traction than my perellis

 

You can get buy with 255/50/17 all the way around or you could go wider on the back.

 

Would that be good or would it be smarter to go wider on the back? I do have a supercharger that i am about to put on, so maybe i should go wider... i wanted to get some bfg kdw's in 17's but the widest they go is 255 so i guess i may have to find something different

 

i say wider for sure then if u have a supercharger no doubt.

 

would it be bad to put 18's on the back and 17's in the front? i dont really know anything about wheels...

 

You can go with different widths, but you loose the ability of rotating your tires. If you can stand it I would stay with 255's all the way around. If you buy a high grade tire it should supply decent traction. When you add the super charger it will not matter if you have 255's or 275's you are going to spin without modification of your suspention.
