Should I Buy these Rims? Pls help

You won't have any problem with the polished aluminum. Aluminum is the base metal so it won't chip (maybe scratch if you hit curbs). I have silver bullits with the polished lip and I find them easier to keep clean than chrome. I armor all the tires and just wipe off the rims. Problem with chrome is any blemish will show and are much harder to keep clean. As the other guy mentioned I haven't head of the tire either.

Only thing I see is that there 18" rims so be ready to feel the bumps.

Good Luck
 
I paid 800 for my Cobra R - chromes wheels. That didn't include the tires. Who gives a ***** about the tires. I look at that as being as added bonus of the deal. Burn those off the rim and no big deal in my opinion. :flag:
 
Your limiter will kick in around 120 mph, so there's no need for Z rated tires, unless you like replacing your tires every six months. Z rated tires usually don't come with tread wear ratings as they only last 20K miles.

As far as chrome vs. polished. I like chrome myself, but that's just me.

As far as 18" rims go, expect to have a harsher ride and higher 1/4 miles times due to the added weight.
