what do you think would fit on a 2007 Z, i am thinking 295/35 19 inch on the rear and 245/40 18 on the front, but the problem is that once i pay, i won't be able to return the rims and tires. plsssssss tell me that they fit , cause i will get an extremely good deal on them

 

oh no! before u get flamed--strange stagger for front and back. usually most people will get a 19 x 8.5-9.5 w/ a 19 x 9-10.5, those tires seem tall as well. do a search, plenty of threads covering tire and rim fitment. also a tire diameter calculator on internet or this site would help u as well

 

The rear tires are 35.9 mm taller than the front. That should look cool.
