Good luck, he only ones I have seen run 305's successfully are John Morgan Evans (modded wide body M5) and 525iEnjoy (525 with Dinan wheels), and 525iEnjoy rubbed - not on the fender, but on the strut. We will see how it works out, should look good, just not sure about the functionality.

 

I'm rolling on 295/30/19 rear tires on OEM 172M wheels on stock sport suspension and no spacers. No rub while driving though it did rub while installing the right rear wheel. At full suspension drop, the inner fenderwell was contacting the tire. Once on the ground, all is well and I felt around back there and it seemed like even a 305 would fit.

 

This is my 525d with OEM style 101 in 9x20 offset 24 front and 10x20 offset 24 rear with 255/30 ZR20 and 305/25 ZR20. I need to roll the rear fenders a couple millimeters.. This is how it look. H&R 35/35 sport springs on the two first photos.





This is without sport springs..

KTlocklear ran the 305x35x19" rears on 19x11 with et28. No rubbing issues and it looked great.

 

I have OEM 172's 19 M5 rims on my ride (8.5 front and 9.5 rear) and have the following tire setup:

255/35/19 front
305/30/19 rear

Perfect fit. No mods on the rear fenders, nothing rubes. Perfect fit. Car has stock sport suspension.

 

305's measure just over 13 and 3/4 inches, why would you want to put that on a 10.5 inch rim? Dont really understand the idea of fitting the biggest tyres possible, they may provide more protection for your rim, but the sidewalls are way too big and will therefore flex alot more and negatively affect handling... 295's are bigger than most people would go on a 10.5... My suggestion would be scrap the idea or switch down to 245's in the front and 285's in the rear, will also give u that extra couple of mm's to let the coilies down a little if u wanted

 

While I agree with you on "not understanding why people try to fit the biggest tires on" I don't agree in my situation. The guy above your comment is running 305's on a 9.5 wide rim!!!!. HAHA so before you call me out do some research and get educated. Check tirerack.com a 295/30 rim width can fit anything from 10 to 11 But the ideal width and the rim they use to test the tire is a 10.5. But nice try So your negative affect on handling comment for a 295/30 on 10.5 needs . A 305/30 can fit anything from 10.5 to 11.5 but ideal is 11. Why would a expert pro site test tire performance on not the correct wheel width?! Step you game up son before you try and call people out.

 

11" wide will fit on the rear as long as your fenders are rolled and your offset is around +25. I am not sure about the fronts but I am pretty sure rolled fenders will help a 265.

 

I have 11" wide +25 offset in the rear with out modifying my rear fenders at all and no rubbing ever.

 

seems as though he was just giving you some advice... Not "calling you out" Dont want responses, dont post.
