I've found the wheel that i like but they only offer 18"x9.5" et 48 in the rear..My current crappy wheels are 18"x10" et 58 with 285/30/18 tires & they're tucked inside the fenders..I like them flush..will this new wheel sits about the same? I know I would need spacer if i want them flush but about how many mm. 10-15mm?

thanks

 

Reducing the positive offset (ET) from 58mm to 48mm pushes out the centerline of the wheel 10mm towards the fender, but the new wheel is .5" (12mm) narrower so the outside lip of the wheel is only pushed out an additional 4mm (10mm - 6mm). A small change (assuming same tires), but in the direction you want to go. Maybe another 5mm or 7mm spacer would bring you out to the point where it just tucks inside the fender?

Personally, i wouldn't want a rear wheel width less than 10" if I was running 285/30's, regardless of the offset. It's within spec of most 285/30-18's, but on the narrow limit.

 

thanks for the info pfbz...I'd decided to look elsewhere since they don't offer 18x10. I order the Forgestar F14 from Modbargains instead.

 

make sure you get the offset right from the getgo as you can customize

 

i want it some what flush to the fender or close to it like 48mm front & 50mm rear maybe ??? its for a NB C2.
I'm waiting on Modbargains to confirm which offset is the best to go with before they have it made

 

10 or 11 wide?

 

10" wide

 

10" flush in my opinion is +35 rear. I like aggressive wheel fitment though. I have 18x11 +35 on my car now, but it is past flush. If you dont roll your fenders, you might want a +45.
