Is anyone running a 255/35-19 tire up front? Are you experiencing any rubbing?

The diameter is 26.03 vs. 25.97 (225/45-18)

I'm thinking of going square all around on 19 x 9 inch forgestars

don't think they'll be any problem fitting those size
it depends on the wheel offset & how low u r going to slam ur car.

I've been thinking about going square on 255/30/20 tires (rims 20x9 et35), the diameter comes out to 26.02 and people have told me that I shouldn't get any rubbing on a stock suspension.

If you go to this thread: http://www.f30post.com/forums/showthread.php?t=863395 you can see some people have larger diameters than us without rubbing.

I have been considering this same setup, but was unsure if it would fit. I've heard 245s will be fine (and certainly 235s) but wasn't sure about 255s without some additional camber.

The other consideration would be to scale down to a 8.5" wheel... but I think if 255s on 9" wheels fit up front, then this would be the way to go.

all depends on your offset

Only up to a point... once the wheels/tires get too wide, they can't fit without sticking out of the fenders.

Being that Forgestar offers a wide range of offsets, the question really is whether the 9' wheel with 255 tire will fit at ANY offset without rubbing issues.

I didn't want to risk testing out the theory, so I went 245 front and 255 rear on a square 8.5 setup. The car is seriously tail happy, not sure it needs any more grip in the front xD

An LSD should help with the tail happiness...

Did you get the Forgestar F14s in 8.5"?

I wish there was a nice LSD option out there But no, I have M3 rims

Wavetrac? Quaife? OS Giken?

Do they make F30 diffs? I haven't seen any reviews on this forum.

I have spoken to the folks at VAC Motorsports (in Philly) and they said they are ready to install a Quaife whenever I bring my car in. I didn't specifically ask about the other two options he mentioned (Wavetrac and OSG), but I imagine they are good to go as well...

I'm running 27" tires (245/40-19) up front with H&R Sport spring with no rubbing ever.

OP, is your car an sedan or coupe? I can't tell from the advice given. I've been wondering the same about up front for my coupe and it's my understanding there's less room to work with up front in comparison to the sedan.

What size rim are you running? I am doing a 19” x 8.5” and looking for a good fitting summer tire and I also plan on doing H&R sport springs after. What do you recommend. Btw I have X drive so can I do staggered?

Are you sure about this?

In this thread there's a guy claiming that's his setup. Post #44 https://f30.bimmerpost.com/forums/sh...d.php?t=797904

No one seemed to really be able to answer whether 255/35/19 would fit up front. I'm really hoping it does because I found a great deal on that exact size. Any further imput from anyone would be appreciated. Thx

255/35/19 fits but if the ET is lower than 29 it will may rub the fenderwell liner while turning full lock, with stock suspension. if it is higher than 42 the inside of the tire may contact the strut or spring perch. it is not recommended fitment on OEM 19x8.

in the future please provide as much detail as possible in your question. don't just ask "does it fit?", it's very vague.

I have been running 19x8.5" ET35 255/35/19 square setup on my 2016 340 for 3 years with no problems. Stock first and the last 2 years lowered with Dinan springs.

Thanks. First post and very much a newbie to cars in general tbh. It's a 320i xdrive on stock suspension and looking to purchase new tires & wheels. I need to do some more research certainly.
