So I got my dpe wheels after 6 months wait (don't ask)! Purchased in 11/2011, never received any update or pictures of the progress from dpe.

The wheels finally came in 4 generic dpe boxes with no specs or paper info. The wheels measured front 20X8.5 and rear 20X10.5 don't know the offset but it is suppose to be specific for e92 m3... dpe kept saying it's custom wheels so that's why it took so long to make...


i thought i was getting 20X9 for the front and that is probably why it rubs in the front because the tire isn't stretched out enough.

I purchased the hankook ventus v12 tires, dpe said these tires should fit
front 255/30/20
rear 295/25/20

the rears are a good fit and overall all the wheels look very nice but i'm that after 6 months I'm still trying to get wheels on the car...








i am lowered on

i have already ordered 2 more hankook ventus v12 in 245/30/20, hoping this will solve the rubbing. the tech at the shop didn't think getting spacers or adjusting the kw springs would solve the rubbing. i forgot to ask about camber though. anyone got recommendations? TIA

p.s. I also didn't know I would need tire pressure monitor kits in order to put the TPMS from the stock wheels into the new wheels... more headache... anyone one know where to buy some?

I am no expert by any means but (and I am assuming based off of the picture) that the rubbing is probably occurring on the front and back of the fender. 20" is a big wheel and you seem to be lowered practically to the max. Raising the height a little may help alleviate some of the fender rubbing, as well as shaving down the inside a little (some companies do that; I think dinan advertises some cars may need to when using their wheels). The smaller tire will help too.

You can order TPMS sensors almost anywhere, but I bought mine through Omar at velos designwerks (got the OEM ones).

tire is too wide up front. 245 would probably be ideal.

[M3SQRD]

The diameter of your 255/30-20 front tire is 0.3" larger in diameter than the stock 245/35-19 front tire. This increase in diameter has caused rubbing on the front fender liner of some cars when the steering wheel is at full lock.

Where is the front rubbing? How badly is it rubbing?

Not sure about DPE but some forged/custom wheel manufactures stamp the wheel width and offset on the wheel mounting face - have you checked to see if there's a serial number as well as the width/offset stamped on each wheel?

[808MGuy]

I run 255/30/20 up front with no rubbing. The V12s aren't abnormally wide so it shouldn't be a problem. My guess is that the car is just way too low or the offset on the wheel is too aggressive.

Thanks for the replies!

the rubbing is in the front tires... back of the fender where the plastic cover/area is. top fender area clears fine. the front fender area next to the front bumper is close but ok.

back fender area rubs very bad to the point the tire pushes into the plastic when wheel is turned. the tech was concern that it would tear into the plastic and expose whatever is behind the the plastic cover (he thinks it's wires for electrical stuff)

also for the tire pressure monitor i was told i need a different mounting kit or a band style sensor b/c the new tire side walls are too thin and the oem tire pressure monitor might puncture through the tire.

What??? I run 255/35/19 no issues on ZCP wheels. You can run a 275 on a 19X10 ET25 wheel and it doesn't rub. Issue is the tire is to tall. Its 26.1" thats the issue.

To the OP the rub is on the fender liner, with time it will just eat away at the part it rubs. You can also try a heat gun to soften it and push it in a tad. Also, why did you mount the wheels? You should have sent them back as soon as you realize you got a 8.5" width wheel when you were expecting a 9" wheel.

Like he said. Duh

The issue

my dpe are 20s. the reason i didn't sent them back is because i TRUSTED dpe in that the wheels would fit my car. it's suppose to be a "custom" wheel. didn't know it would be a problem till after mounting the tires and putting the wheel on car. i'm not an expert on car stuff. also can't believe an extra 0.3" tall causes so much problem

as stated in my original post dpe customer service is pretty much non existent... who knows how long it would take to get the wheels changed from 8.5" to 9"

thanks for the suggestion of using heat gun to soften the plastic. is there anything important behind the plastic cover? wires?

[tha_good_life]

I would try going 245 in the fronts. Your car looks very slammed. Perhaps raising it a little will help too. Check out your alignment. You might need more camber. I'm surprised you are not having issues with the rear. i'm running 295 on Michelin PSS and i recently rolled my fenders.

Did you tell them how much you're lowered? The tire also affects rubbing - are you running their recommended tire model & size?

You might find that the wheel doesn't rub if you're at stock height with their recommended tire. If you didn't give them all the info about your setup and follow all of their advice, I hardly see how you can blame them.

Ok you are running 255 on zcp. what offsets? any spacers? are you dropped? im assuming OP is rubbing in two areas which would be the fender when fully locked and the fender liner when turning. He is slammed which I'm sure you are not. I stand by my 245.

Im running 245/35/19 up front with a 19x9.5 et22 no rubbing, no drop, no zcp. you raise the wheel diameter and drop the tire height so from 245/35/19 you go to 245/30/20. so it should not rub. This is still assuming op has proper offsets up front.

[tibra1]

You gotta be prepared for this if you gonna plus size to 20s and lower the car..this car already has such tight tolerances especially on full lock turns..

the tire was already rubbing the fender liner(plastic cover) when the car was still on the lift before the car was put back on the ground. my springs are adjustable but the tech at the tire shop didn't think raising the car would help with the rub problem. dpe never recommended any specific tire model or size. i told dpe what tire sizes(front 255/30/20, rear 295/25/20) i would like to run after reading this forum and i assumed dpe would custom make the wheels to fit my m3... for $4k and waiting 6 months i really expected more from dpe

anyways the hankook ventus v12 in 245/30/20 should be here next thursday from tire rack so i'm hoping the fitment problem will be fixed!

[avex8]

I have the DPE 20' SP SC-5 20x9 front and 20x10.5 rear running hankook vents v12 255/30/20 front and 295/30/20 rear, i am lowered on H&R spring and i am also using 15mm spacer in the front. No rubbing here.

You can order TPMS sensors almost anywhere, but I bought mine through Omar at velos designwerks (got the OEM ones).

I want to transfer my oem tpms to the aftermarket dpe wheels but the tire shop said the mounting area is different and if the tpms were mounted it might poke through the tires (the new tires are lower profile). the tire shop said to get a mounting kit or band style sensor. i found some on this website but have no idea if i need both or what?
http://www.tpmsdirect.com/TPMS_Adapters_s/1376.htm
http://www.tpmsdirect.com/TPMS_Strap_Kit_s/1373.htm
also seems like it might be cheaper if i were to just buy new tpms http://www.m3post.com/forums/showthr...essure+monitor but not sure if these would fit the new dpe wheels (Adjustable from 20-40 degrees)

these are my wheels

[C|3R1C]

TBH I dont know what the mounting point looks like so I cannot comment, however the OEM ones are adjustable too... what does he mean poke through??

yeah i'm pretty sure the 20x8.5" vs 20x9" is what's causing all the fitment problem.
did u need the 15mm spacer to make the front tire not rub or u just have it for more aggressive look? how does the car drive w/ 255 in front and 295 in the back? did u have 18s or 19s before 20s?

I had the 15mm to make it look more aggressive. The 20's feels the same to me compare to the zcp wheel i had.

[M3PO]

Sounds like width isn't your problem, diameter is. I run 255 width tires up front with aggressive offsets and spacers and it doesn't rub on the edge of the wheel. I had some very slight rubbing during turns but now that the tires and/or the fender liner has worn, it's not an issue anymore. If you are only rubbing slightly on the front and/or back of the fender liner, I would not worry about it.

[LarThaL]

Whether or not you rub with a 255 tire will depend completely on the specific geometry of the tire and how tapered in the sidewall-tread interface is. This is going to be different for almost every tire out there. The tolerances are just so tight. Even with my stock ZCP wheels and stock Conti tires, I only have about 5mm clearance on full lock.

Problem with then going to a 245 tire out front for the OP is that a 245/295 stagger is quite large.

After really going over all the possible combinations of everything a zillion times with looking at all the pros and cons, I have decided to stay with stock sized tires. I will just upgrade to Michelin PSS from my Conti 3.

[atyps]

Installed the hankook v12 245/30/20 today. Still a little rub at certain points when turning but drivable. There's about 7/8 inch difference in the offset of the dpe vs OEM 19s. The dpe sticks out 7/8 inch more which is why there's rub. I posted pics of OEM 19 compared to the dpe 20 diameter wise and also what it looks like behind the front fender plastic liner (no wires just metal frame). Going back tomorrow to get alignment and maybe camber adjustment. Cleaning and detailing next week.
