I'm going to get my car lowered today using eibach pro kit and I need to know what tire size I should go with my new rims. I'm getting the 18" Black Magnum wheel, you guys think they will look good on my ride? I'm thinking Nitto drag radials 305/40/18 rear and 275/40/18 front, Suggestions?

 

What width wheel? Tires can take an extraordinary amount of abuse when it comes to misapplication, but I highy reccomend checking out the engineering data on your tire choice and getting the right rims for the tires (give Nitto a call and ask to speak to the techs, unfortunately they will probably treat you like a newb, but at least get them to explain thier reasons for doing so - don't feel slighted, but the buying public is probably 40-50 years behind what these guys are doing and thats no B/S! People still use the old alpha/numeric system for determining the width of tires (F70, G60, N50, ect), still think new tires should only go on the front, and still think you cannot cross-rotate radial tires).

And right off the bat there's nearly an inch of difference in the O.D of your current tire pick front to rear. I dont know if there is a provision for disimilar wheel dia's in the computer (I'm guessing there isn't since the last programmer I had didn't have a seperate input for front and rear revs per mile). If you keep the dia's nearly 27" front and rear, it will reduce any problems you might have without having to resort to a programmer to correct wheel speeds. Anything else should be reprogrammed.

 

Wow, a 275 front on the street? Talk about a huge scrub radius. It may also rub lock to lock. 18x9 and 18x9.5 should work fine.
