Titan Wheel Thread - 235i Square set up thoughts
I've read, researched, and I know a bit more lol
Wanted some thoughts. I have a 235i on stock 18/7.5 wheels, RFT. I'm moving to Michelin A/S3+, I simply drive too much under 40-45 degrees for PS4 (no rain/snow), and have no interest in changing tires/wheels out twice a year. Still soild upgrade over RFT's 1) Are APEX/VMR type rims (read price) as strong as stock ? 2) I'm going squared and not interested in going 8.5" in front, so 18x8 all the way around. Is 245/40 possible, or whats better set up, or stick with 235's ? Don't want any rub, and believe I can do w/o adjusting camber on 8's. 3) Off set - I want no poke, in fact with fenders, rather be a hair under. Is 45 best, or can I go 40 ? 4) I want black rims, probably gloss, and could spend up to $500/per, rahter stay in $300-400 range. Mostly street driving, and maybe some lite club events. Love the VorSteiner wheels, think only one non black fits...arrgghhh. Love VMR 802's in black, but only 8.5 (I have gray, and blacked out front) Like the Avant Garde M359 too....I can't find great info on how good/strong certain wheels/manufactures are. More $$ the better, but just a 1 piece forged ok ? C Love some thoughts, suggestions esp on wheels/off set Thanks ! Last edited by 4Hockey4; 03-23-2021 at 03:17 PM.. |

2) These are the AS/3+ sizes for tires that you might put on an 8" wheel: Offhand, the 245/35 seems to offer the most tire. However, if you don't want a 35-series tire, then the 235/40 might ensure a better fit as it exceeds the OEM tires' diameter by less than does the 245/40. Other owners may have specific information regarding the fitting of these differing sizes.

This guy has squeezed 245s on 18x8 wheels... although not the brand you're asking about.
I'm in a similar conundrum with a smaller budget. Interested in others' replies. In my case, though, I'm keeping my stocks for winter and the new ones are strictly summer only, so strength and finish durability aren't as much of a concern for me. Makes life a little easier. |

Thx for info - I'd love to go 245/35 on 8.5" rim, but hear that on front that isn't good/rubbing, plus changing camper and arms in some cases.
Yea saw his post, the 245/35 on 8" would be awesome, but really limited on wheel options. Would a differrent wheel/non custom 45, work ? His 43 offset is good, so I'm leaning 45. huh guess i could keep stock Pirelli RFT for winter/lower temps...and go back ass for summer....hmmmmmm Last edited by 4Hockey4; 02-29-2020 at 06:16 PM.. |

I'm of the opinion that the average owner on this site who is contemplating something like the OP would be well-served by consulting with a local shop that knows BMWs inside and out – assuming one is available, of course. Failing that, Bimmerworld (or, perhaps, one or more of this forum's sponsors) can be called on for reliable and expert advice.
I've bought both wheels and tires that wouldn't fit on previous BMWs. Those instances were because I failed to do enough research, and they happened on cars that were easier to sort out than our cars are.

Over here in the UK, the stock M235i setup ex-factory is
F: 7.5Jx18 225/40 R18 92Y R: 8.0Jx18 245/35 R18 92Y With various other options certified e.g. 7.5Jx17 square for winter, F:7.5Jx19 R: 8Jx19 summer etc. but not the setup that you envisage. So I think you have to ask yourself what it is you expect to gain from what you propose? Remembering that this isn't a setup that BMW has tested for certification. What you propose will change the handling - so do you know exactly what effect this will have? Fine if you do (as is the case for many on here) but worth my asking the question, especially if you're less certain. I'm with @dradernh and I think that "What are you trying to achieve?" will be the first question that a reputable specialist will ask.

I run effectively offset 40 (45 and a 5mm spacer), but I have 8.5" wide wheels. 45 might work on an 8" up front. |

Still digging, wondering if I should do down/charge pipe, MHD tune, and just upgrade to the PS4 in 225, and add LSD. I could hold on to the RFT for winter. My goal is to get more rubber on ground, as I'd like to do some lite club/track events. LSD>More rubber ? Biggest issue is having to buy decent rims, and LSD isn't much more. Like to add some power, but not spend $8k |

25.1" and 25.2" are the diameters shown for the four 225/40-18 Pirelli RFTs on the Tire Rack site. Of course, that's for new tires with 9-11/32" tread depth.

Need to figure out how much tire/width I need if I push to 400hp with MHD/Downpipe/intercooler. Would a 225/40 PS4/AS3+ be sufficient, or need to upgrade wheel/tire width. ugggh... |

Seen some posts where 8.5 was too big on front...no issues ? I'd probably go 45 off, don't want quite flush with fender. (wonder if that is issue and need to push to 38, don't want ANY poke)
Nice look, no issues with strength ? APEX and VMR similar in strength ? What tires are those ? $304 not too bad and makes tires easier. Does APEX have local dealers ? Web site doesn't really indicate. Thx for info all Last edited by 4Hockey4; 03-01-2020 at 02:18 PM.. |

I think that would be wise. It's too easy to spend money that later you wish you'd spent on something else.

Dinan lowering springs. No other suspension mods. Have run rsrr (in 235 which fits like 245) and ps4s. Slight rub on big hits.

I have added down and charge pipe. LCA, shifter going in few weeks, pads/lines/fluid also. I need better tires
I've read every thread here and other sites. I want to go 245/35, and will not be lowering car. Should I find an 8" wheel ? I know folks go 8.5, but so many places show 8 with standard 45 offset ideal. Zero rubbing, issues with strut etc. (and can go Dinan) Also chatted with a few folks and they drive PS4 year round, says take easy under 40 degrees until they warm...one guy runs at track at 40 degrees out, so does a lap or 2 to warm. (some folks say dont even start the car under 40 !! ) 3 different shops says Flow Formed (Apex etc) just fine for light track duty...crazy many track folks scream "forged" !! or don't bother. Thx for thoughts |
