Hey guys I didn't find any threads already asking about the questions I have so If there was sorry about this. But I had some questions about some new wheels and Tires for my 2010 GT. I was looking into buying some new 20" chrome foose nitrous wheels as well as new tires to replace the stock gt premium 19" wheels that I have now. So my concern is the tires that I was looking at were the nitto NT555's which would come in 255/35 - 20s for the front and 285/30 - 20s for the back. Right now I have the Pirelli 245/45 - 19s all around and to my understanding these new Nittos would be a little smaller which would make my speedometer read incorrectly wouldn't it? If so then is there away to adjust the speedometer for the New wheels and tires to read correctly? And my last question was whether or not anybody has already purchased these wheels and how they like them?? Pictures are encouraged :gringreen Thanks!
