235/45/17 tires rubbin the control arms (suspensions) is it true? I had..
I had 235/45/17 twice already but this time I took it to a local shop cuz the alternator was bad and secondary air pump issue, they said my tires are rubbing suspensions. The stock tire is 225/45/17 but i went up to 235/45/17 cuz people told me it won't create any problems... But it seems like it is... (also this is the first time im putting kumho tires on my S4). Do you think its the tires that are defected? or is kumho tires are slightly larger in width?
anyone?
Also engine light came on and the code was sayin "torque converter & cam tensioner" the shop believes these codes are caused by the tires i have on.... can anyone tell me if I have to get a new set of tire? or just go back to the OEM size tire?
thank you so much for readin...

The shop told me there are tire marks on suspesions rubbin with the tire I have now....
They also said if I want to go from stock 225 to 235, then I must change from 45 to 40 as well. so it should be 235/40/17, not 235/45/17. I believe what they are trying to say but Im not sure going 235/45/17 will going to harm the vehicle and put an engine light on like "torque converter is bad.." Have you heard 235/45/17 does harm to S4? with stock rims TTT?

Well, yes, it makes sense if you maintained it at the 45 aspect ratio, your circumference will be
larger in addition to the tire being wider, which increases the chance of rubbing.
It won't mess up your torque converter or differentials or anything like that, since your tires will still all be the same size, but it definitely increases the chance of rubbing (in addition to throwing off your speedometer).
You should always vary the aspect ratio accordingly when you're changing width.

Not all 235/45/17 tires are the same. Did you switch brands with this set?
Tire sizes vary between manufacturers. It's possible that the margin for error with the previous 235s was so small that changing to a slightly wider tire brand resulted in rubbing.
If that's the case, you should have enough outboard clearance with the stock wheel offset to add a small spacer and stop the rubbing.

I rubbed using 235/45/17 with the stock tires and suspension
When I went with aftermarket rims with a 35 offset that fixed the problem. Evan after lowering the car. Then again like someone mentioned, not all tires are the same(I was on Toyo T1-R).
