I need to find out a definite answer before I sell my wheels that I would really like to hold on to....I want to put an 18x8 w/ a +12 on the front with a 245-40-18, and a 18x10 +15 with a 285-35-18 on the rear...I really would like to know if this combo will require rolling the fenders or may stick out to far...I cant just bolt them on to find out at the moment since I dont have the spacers or correct tire size for the car just yet, so please dont tell me to just "put them on"...Also one last importiant detail to throw in is that I would also like to lower the car about 1.0-1.5"...Any wheel and tire gurus that could help me out here would be greatly appriciated...!! Thanks !!

 

Anyone at all???

 

The rear's should be fine. The front's should sit flush with the fenders- it would be like adding a 20mm spacer to 18x8 oe wheels. I think you'll be ok.

 

So you think with 25mm all around I would be ok??

 

No, what I'm saying is that your wheels should fit.

 

Gotcha, just trying to avoid rolling fenders if pssible..

 

The fronts will fit(already rolled).

 

what tire/wheels specs are on the car right now?

 

Factory 17s on the car right now...The wheels I want to put on are from a different car with the same bolt circle, but different offsets...

 

Well, I can tell you this much. Your new front set-up will be ~1.5 inches wider than stock and 0.2 inches shorter for overall wheel/tire height (this depends on tire choice, of course), and for the rear, ~2.6 inches wider than stock and 0.4 inches shorter for overall wheel/tire height (depending on tire selection). Hope this helps some.

 

Yeah, I just will be pissed if I order up the 25 mm spacers and they kick the wheels out too far...I have been searching constanly trying to find out if this will work or not...Seems like everyone goes 8.5 wide in the front and 10.5 wide in the rear, so I have been trying to calculate and compare in my head a little to what everyone else has...
