Needing some help on OD for AWD coupe
ok so i dont mean to repost or anything but i've come down to some much wanted specs for wheels and I just wanted to know if this would work on an awd coupe
offset would be F +20 R +25
F 235/30/20 R 255/30/20
if not, please could someone give me some sort of formula for calculating a proper OD for staggered wheels on an X coupe
ive also seen offset F 32 and R 42 which looks very nice as well

For AWD, the diameter must be the same on all 4 wheels. Check out this web site to calculate your diameter.

no it doesnt need to be exactly the same. as long as your less than 3% your fine.
245/35/20 275/30/20 is 1.1%
245/35/20 285/30/20 is 0.1%
im getting the first combo and will update when they arrive. if it doesnt work out then il get the 285 but im not worried about it.

im sure it will look great and the fact that ur going with 275 will show off the wheel a bit more right ? but with your help i know now that this will totally work. and just to make certain with you going with 275 that would mean that the rear tire is slightly not as tall as the front one?

no problem. im getting the 275 because i was worried about rubbing with the 30 offset. if i have an extra 5mm of space then i will get the 285's.
the height difference is minimal between the 245 and 275, resulting in the 1.1% difference in circumference. theres a guy running over 3% on his FX with no problems. some say 3% some say 5%, stay on the safe side lol theres plenty of options

Simpson, I think you calculated the second OD incorrectly...
To calculate the overall difference between the two tires, take the larger OD and subtract it by the smaller OD and then divide by the larger OD. ie. for 245/35-20 the OD is 26.8 and for 285/30-20 the OD 26.7. Therefore we have (26.8-26.7)/26.8 = 0.37% difference in the two ODs.
GL with whatever tire you choose =D

Not to thread jack, but it may be easyer then starting a whole new thread...
how do you guys feel about this set up on a Gcoupe AWD
255/40/19 F +30 8in wide rim
285/35/19 R +25 9.5in wide rim
id only have a mild drop at the very most, Eibach prokit (1.9/1.2 if i remember correctly)
