I bubbled two of my 18" PSS on a pothole and I liked these wheels in stock sizes so much when I was using them in Stock-class autocross that I was planning on buying another set anyway with 275/285-35 PSS for street use. Unfortunately the 275/35-18 PSS is back ordered for at least a couple of months. So I bought the Contis instead. Upshot is they're a bunch cheaper and I got to use a 295 rear tire which is a little bit better fit for the car. Downside is it's an inferior tire. Tire Rack as always was awesome to deal with. Everything arrived fast correct and balanced perfectly.

Wheels are 18x10 et25 all around since I don't care about Stock class anymore. The rears are just a hair pinched but it's not bad at all with the 35 profile.

Tons more front grip relative to rear, and longitudinal grip seems better even with less than 50 miles on them. Probably about the same overall grip as the PSS if I'm honest and you can definitely tell this tire doesn't have as stiff a sidewall as the PSS and there is a ton more tread squirm. But these are new 10/32" tires comparing to my approx. 7/32" and 5/32" PSS so I will reserve judgment.

Ride is actually slightly better probably due to the softer sidewalls which are just about the same height as stock.

There is room for a 315 in the back as I already knew, and the 295/35-18 on a 10" wheel leaves at least another inch.

This setup is 13lb lighter than the worn 219M with PSS in OEM sizes, probably more like 15lb new to new since tires lose a good amount of weight as they wear. Anyway I like it. Hopefully the PSS will be in stock when I need to replace the tires on these!

Mounted profile photo of the 275 and 295. 295 is not much more bulge than the 265/40 PSS (which runs a little wide) on a 9.5" wheel

Damn app isn't uploading pictures today. Oh well.

Last try

Last one. Stupid app.

Nice setup! Thanks for your business and thanks for posting the pics.

Those DWs are definitely very good grip for the money. As you noted, I don't find the handling quite as crisp as the PSS, but overall it is very good, esp for what you pay.

As I recall from the C&D/TireRack test of street tires a couple of years ago, the DW was the worst in the dry autocross by a good bit (winner was AD08 with the PSS just 2/10ths behind), but it was excellent in the wet.

Setup looks nice though! I'm running 19" OEM on street with PSS 255/35 and 275/35 -- nice setup, just one size larger than stock. I'd be curious to know if you have any tramlining (or will once the fronts wear in more).

[Richbot]

It's not tram lining now but I will definitely have tram lining once they wear a little as even in stock sizes It likes to sniff pavement seams due to the small amount of front toe out I'm running. It's definitely more pointy and the wheel is more sensitive with the nice wide wheel and tire and good sidewall support on the front. There is no dead spot at all on center anymore. Corner entry is much more controllable with trailing throttle and you don't have to be all arms and brakes to get it to take a set. It does take longer to take a set thanks to tread squirm and sidewalls. I'm running them at 38psi which helped some with that.

Fuel economy is identical now that I've got a few tanks, even with the wider tire and worse aero that comea with it, and Accel in gear is better according to Harry's so I guess losing the rotating weight was worthwhile

I figure I'm just about even on lateral grip with stock sized PSS given I'm 30mm wider. It sure feels that way but it's hard to say for certain without more controlled conditions. Balance is better too. Longitudinal grip feels quite a bit better now that I have some miles on it, to the point I added some bump damping to the front to keep the bumper off the ground under braking...

Love these wheels they just look right on this car, and the tires look perfect to me. I do wonder how a 255/40 would look on te 10" wheel. For a street car I'm not sure the 275 in front is worth it. That's why I go through tires so fast, experimentation

[CSBM5]

I hear ya, I'm the same way with tires and wheels. I've got three sets for the M3 now: OEM 19s with the PSS, stock width MT1s with 275/35 Rivals all around (SCCA autox), and just recently got a set of Apex ARC8 in 10x18 with 275/35 NT-01 all around.

Three different experiences with the above for sure!

Curious to see if any of the tires you have are manufactured mid 2012 or after.. I've heard from tirerack that they upgraded some sizes of this tire (245/35/19 for example) around that time so has a higher speed rating as well as load rating (XL). They reinforced the sidewall around that time so wondering if you see a difference. If you see XL load rating on any of your tires, it should be the updated version.

I just upgraded all 4 corners with this tire as well with stock sizes recently but my fronts are from mid 2011 and the rears were not updated. Have the tires set at 34 psi front 36 psi back but definitely feel the soft sidewall and tire squirm on hard cornering. Will try upping that to 38 this weekend to see if there's a difference. I do notice the lighter weight upon hard acceleration and the car feels much nicer going over the terrible NYC roads (even softer than my winter set with blizzak lm60!)

Would have gone pss if I wasn't returning this car in 6 months.

Good day

I was wondering if you could help me answer my questions. Ideally I would like to mount my g-force rivals to my Volks but some people say my set up will rub. Hopefully you can add some insight to this. My research tells me I can run the g-force rivals with the Volks...heres my initial post.

Cheers mate


I have two set of rim..as follows and two sets of tires...whats the best fitment with no rubbing / issues, currently running Ohlins road and track with Ground force camber plates

Apex Arc-8s 10.5 et27 and 9.5 et22 18s

Volks Te37SL 10.5 et22 and 9.5 et20 18s

Hankook RS3 285/35/18 rears, 265/35/18s front

BFGoodrich g-Force Rivals 295/35/18 rears and 275/35/18s front...

Whats the best combo...?

I have no personal experience with te Rivals on an M3 but based on how my tires fit you should have no issues at all, depending on what your front suspension is you might need a small spacer in front but rears should be fine

I will check on the DW date codes. Pretty sure they are 12 or 13 construction. Load ratings are 97 and 99 XL which is the same rating in front and 2 less rear than stock

There is zero debate whether the rivals will fit your te37's. They will not. I have tested them on 10.5" et25 wheels and they barely fit, not more than 1mm of clearance. It's not going to happen. In addition I'm not aware of anyone else who has even test fitted 295/35/18 rivals besides myself. Anyone who hasn't actually tested that tire is guessing because it runs very wide. I'm not basing my recommendation on theory, it's actual testing. I have also tested other tires on te37's to confirm 295's are a no go on that wheel... Unless you wnt to rub the paint off of your fender.

I have tested 295/35/18 rivals on 10.5 et25, and 11" et25. See your other post; I added pictures. http://www.m3post.com/forums/showthread.php?t=978205

Late 2013 and early 14 date codes. I guess people are buying these if they are selling tires that new

Richbot,

I have been reading your posts re tire sizing for a while and trust your judgement. That said writing to this post as I too have a set of 18x10 et25 wheels all around.

Got them to run 275 ra1 square on a stock suspended non zcp. With -2.5 camber up front, rear grip at exit or fast sweepers are a challenge now.

Not interested in getting another set of wheels. That said, was contemplating on running 275/35 and 305/35 with these. Would the fears fit? The stagger f/r of half inch is comparable to factory. Thinking nt01s.

Thoughts/suggestions?

Cheers!

Haven't tried that tire but given the 315/30 hoosier fit comfortably on my car I think there is a good chance it will work, though the 305/35 is a good bit taller, there was still plenty of room in diameter with the hoosier. Not optimal on a 10" wheel obviously but will add rear grip at the expense of precision and if you don't want to change wheels, an okay option. Though with teh nt01 i would try the 275/35 front paired with the 275/40 on the rear first and see if that gave you the results you are looking for. A taller rear tire of the same width will put down the power better on corner exit if that's what you're lacking, and will also add some static rake to the car which shifts corner weights rearward.

Thanks for the wisdom. Ended up getting 265/35
295/30 r888 on 18x10 et 25

Last question, would you reccomend 5mm spacer on the front to get correct offset (leh keen would run this) since now the rears are a tad outwards? Or leave it as it's very marginal to know?

Thank you again.

Cheers!
