I'm looking at summer wheels that have the following spec:

Front: 18x9.0 ET29
Rear 18x10.0 ET40

I'm looking to wrap them with front 245/45/18 and rear 275/40/18.
Would 235/45/18, 265/40/18 be better?

I have a RWD 2018 340i with stock msport suspension. Want to know if this fitment is too aggressive, I don't want to play around with fender roll or camber or anything.

Thanks fellas

the outer shoulder of a 245/45/18(26.7"dia.) @ ET29 will rub the fenderwell liner when turning at or near full lock.

235/45/18(26.3")+265/40/18(26.3") or

255/40/18(26")+285/35/18(25.9"), this will have slight poke

will fit on ET29+ET40 with no issues

i have yet to see 235/45/18+265/40/18 on 513M, therefore no pics. however i know it will fit without issue

the link below has 255/40/18+285/35/18 on ET30+ET40 on a lowered F32. your rear fitment would be the same but front would poke 1mm more than this

Perfect info, much appreciated.

I’ll post a photo if/when I snag them. if anyone decides to go a similar route I’ll be the guinea pig haha.

Kind of related, but I don’t have the Mperf brakes, mine are just the standard brake kit. In your opinion would it look a little off since the calipers won’t be painted and rotors aren’t anything fancy? Given that the 513M is a pretty open design. I haven’t yet found a photo of an F30 running 513M with the stock brake setup.

i wouldn't say "off", however it'll definitely look better with colored calipers.

you can do a spray on caliper paint but it'll require you to mask off the whole car from overspray. there is also brush on caliper paint which flows glossy and looks pretty damn good. just takes a bit of time while masking or painting carefully near areas you do not want painted. i may try this brush on method myself.

here is a vid(of many on youtube) of brush on

Thanks so much man. You’ve been a massive help. Cheers!

i had 513m with regular brakes, but i did upgrade soon after.

Wow. This looks so clean. I was thinking about going aftermarket wheels, but I'm thinking I want to do OEM+. 513M is such a beautiful wheel and is probably my favorite OEM wheel next to 763M.

Are you still running them? Since you're xdrive im assuming they are a squared set?

Also, How much did the brake upgrade cost? Was it worth it? Did you buy the set used?

I apologize for for all the questions lol

no worries, happy to help. you're correct, the 513Ms I ordered new from BMW to get all square front wheel set-up. and yep still running them, i'll never get rid of them they are by far my favorite wheel design and set-up for the F30. and i do really like staying OEM/OEM+ with my cars.

i ended up doing the m performance bbk, a couple years ago BMW discontinued the orange BBK and replaced it with a new part number, all remaining stock was sold for a steep discount, so I snagged the kit for about $1,000 new from my BMW parts dealer. just had to get rear rotors which were about $200 if my memory serves me right. the kit doesnt come with rear rotors but comes with everything else. unfortunately that deal came and went, you will probably look at spending closer to $2000 to run the same set-up these days.

there's probably more pictures and details in my build thread, you can find it here: https://f30.bimmerpost.com/forums/sh....php?t=1878022

Youre a legend. I’ve actually browsed that thread a couple times and absolutely LOVE everything you’ve done.

How much did the 513M’s run you? I found a used set for $1800 without tires and a bit of curb rash on one wheel. Thinking that’s a bit high?

thanks man... i've always advised the RWD guys to get a used set from F80 classifieds, or even our own classifieds. The only reason I bought new is because its harder to find a square set, I spent about $2300 for just the wheels, another 800 for tires. You can easily find a staggered set with tires for about $2000-2300, and that's for mint condition wheels... obviously with curb rash and other damage they'll be sub $2k. I wouldn't say 1800 is a bad deal necessarily, it's just you get a lot more for your money when you buy a used set that comes with tires. Ultimately it's up to you, but I'm sure you know new tires, especially for the rear wheels, can be quite expensive to buy new.

I’ll look around in f80 classified to see if if I can find a set that will fit on my car. What tires did you buy? I’m looking at around $1.5k for PS4S in the size I need

yep good set of summers like the PS4S are a fortune. if i were in your shoes, I'd 100% look for a set with tires already on. my car is a year round daily so I bought a set of DWS6+ Continentals all seasons 255/40/18 on all 4 corners.

have you seen this listing? https://www.facebook.com/marketplace...1732368129277/

good listing, I messaged the seller. But if I paid asking, it would be about a wash. if I went with buying just the wheels and buying tires separately, it would be just under $3k.

Do you think 275/35/18 would fit rears?

Btw thanks for finding that, i live in NY and for some reason that listing didn’t populate on marketplace for me when I was searching. Maybe it was outside 500 mi

yeah its the only 513m listing I see on my marketplace and I saw its more towards upstate where you are.

others would have to comment on fitting tires in rear, hard for me to say with both being xdrive and also only ever researching 1 set of wheels for my car. my knowledge about what is and isn't possible for RWD F30s is nonexistent.

Gotcha. You’ve been a huge help here man, I appreciate your time. Thanks a lot

245/40/18(25.7")+275/35/18(25.6") will fit the rear, however i didn't suggest it because at m-sport suspension height, the gaps will increase due to decrease in tire diameter/sidewall height. here is what what 245/40+275/35 looks like on a lowered F30
https://f30.bimmerpost.com/forums/sh....php?t=1445526

just a thought...i understand the concept of desiring OEM/OEM+, however in your case i'd consider Apex VS-5RS as it is very similar in appearance, lighter than 513M by a couple lbs, fit BMW centercaps and comes in four different colors. 18x9 ET30, 18x10 ET40 is virtually identical specs with just 1mm less poke up front, which is a good thing...

i agree, the VS5 RS are the only other wheel i’d consider as a 513m alternative. especially if we’re specifically talking about 18” only wheels
