anyone have an idea what size and offset is overboard for the front and rear. im looking to get something sitting flush with the fenders. i dont wanna go to big in the front and find out i can only go straight. as for the rear i wanna go wide as possible. 245's on my rear rubbed on my fenders on bumps. otherwise they were fine. havent tried them in the front. so if anyone has some good numbers for this please let me know. right now i got 17's with 225/45/17 tires. im looking to get 18s 18x8.5 or x9 maybe?

 

18" Murano rims with 235/45/18 a 2" drop. Never had a problem.

 

Base values for flushness in the front.

9" +38
8.5" +32
8" + 26
7.5" +20
7" +14

These are fairly conservative and I don't account for the decimal place (Unit of error is 1mm for every reduction of 1.5" of wheel width from baseline 9"). There is definately more room to poke out more then camber in as needed.

For the rear add spacer to match. Or if you want to stagger.

10" +41
9.5" +35
9" +29
8.5" +23
8" +17

Again did not account for the error. Obviously you can stray +/- 1-5mm and still be close to the fender if the wheel in question does not match the criteria above.

Not my words.
