Which does everyone prefer on a 17 X 7.5 rim with 48mm offset?

Think wagons get rubbing with 225's. Sedans are OK.

i think psoper run 225 on 17's and it's a wagon. you might want to check with him. I don't think he has any rub...

I have a sedan, so I guess I will be ok with 225's. Thanks, 'cause that's what I wanted to hear.

Why does Subaru recommend 215's on their BBS 17's instead of 225? (I guess then it will fit sedans and wagons)

I got this a while back from an i-club member. it might be handy... :)

205/55 R16 for the WRX.
this means a diameter of 24.89in.

Other sizes that are close to this diameter are:
225/50R16 (24.86in)
215/45R17 (24.61in)
225/45R17 (24.97in)
245/40R17 (24.72in)
225/40R18 (25.09in)
245/35R18 (24.75in)

Wide/Asp. Whl Diameter

205 / 55 R 16 24.87795276
215 / 50 R 16 24.46456693
225 / 50 R 16 24.85826772
215 / 40 R 17 23.77165354
215 / 45 R 17 24.61811024
225 / 35 R 17 23.2007874
225 / 40 R 17 24.08661417
225 / 45 R 17 24.97244094
235 / 40 R 17 24.4015748
235 / 45 R 17 25.32677165
245 / 35 R 17 23.7519685
245 / 40 R 17 24.71653543
205 / 35 R 18 23.6496063
225 / 35 R 18 24.2007874
225 / 40 R 18 25.08661417
235 / 35 R 18 24.47637795
235 / 40 R 18 25.4015748
245 / 35 R 18 24.7519685
245 / 40 R 18 25.71653543

the Aspect ratio is the percentage of the width... so
a 200/50 will have a sidewall height of 100mm. So to
calculate final diameter, you take the aspect*0.01(to
make it percent)*width/25.4(mm to in conversion)*2(two
sidewalls in total diameter)+wheel size

so a 200/50R15 works out to:
15"+200mm*50mm*.01*2/25.4 = 22.87in.

225/45/17's the way to go. :D

for wagon, not sure, you'd probably want a 52+ offset.

GC? or GD?

I have 225 on GC body so GD should be able to do 235 at least.

If you go to a 225 on a wagon, make sure you have a wheel with at least a +50 offset. There is a guy who lives near me who has a lowered wagon with 5Zigen Fighters (17x7.5) and 225/45/17 Nitto 455's that doesn't have a rubbing problem. The wheels have a +50 offset. I've also corresponded with others who have +50 or greater offset wheels that don't have a rubbing issue.

A lot of people who buy the Rota's (17x7.5, +48 offset) report rubbing problems with 225's. The 2 mm seems to make a difference.

The other thing to consider is the tire you are planning on getting. Not all 225's are created equally. The Azeni's and HRZ II's have a section width of 9.1' while tires like the BFG KD have a section width of 8.9.

Again, I have a sedan. So there shouldn't be any rubbing problems with 225/45-17s on Rota Tarmacs with a 48mm offset.

Aren't Kumhos relatively wide compared to others? I need to get some "value-minded" tires. Probably Kumhos or Falkens.....

I'll let you know how much I like or don't like the Kumho MX's when I get them!
