E46M3 of course :D

Unfortunately, after the sale we sometimes get very little feedback on how certain setups are working out. Rather than search, I thought it would be helpful for future reference to have them all in one thread.

Anyone care to post their own specific experiences in going from the stock 225/40R19 front, 255/35R19 rear to the wider 245/35R19 front and 275/30R19 rear? Did you find that the wider tires were mostly a cosmetic issue, did the tires tramline more, etc?

Thanks in advance for any feedback

I would like to know if anyone is happy going larger than stock with the 18's too!!

Very much so. I've gone to 265/35-18's all the way around on my stock 18s.

My experience is with both 255's and 265's up front. The wider front tires tramline a bit more and also increase the steering weight/feel. If performance is your goal, larger front tires are absolutely worth it!

Are these on the stock 19's?

I was thinking about getting the 245/275 set up for my M3 I have on order and putting them on when it comes in. Is there any rubbing issues with those sizes on the stock 19's?

:dunno:

Oops, forgot to specify that's on stock 18's. But I don't see how 18 vs. 19 would change things.

245/275 will fit fine.

most people who bump up to the 19's also bump up the tread width and 245/275 is the closest to +1 size from the OEM tread.

I am running 265/30f and 275/30r and love it. I am not on stock wheels, these sizes can not be run on the stock wheels, but the almost neutral steering with this set-up is amazing and exactly what I was looking for.
I have not found any tramlining at all with this set-up, but that is more to do with the tire's tread pattern than wider tires.
It is a bit noisier than the stock set-up, but running 2deg neg camber will held generate a bit of noise.

I have run 245/265 on the stock 18s for track, and they fit/work fine.

But I would go to the 265 all around, and will do that when I need new tires. Nicely dials out a lot of the understeer.

265's fit on the stock fronts or will you be using stock rears all the way around? :confused:

They will fit on stock fronts, but rears all around is better way to go.

On a similar note, what tire are you guys running for the larger set up. I did a search on tirerack and got some 8 or so results.

I've got the Competition Package wheels that I got from Turner Motorsports with Michelin PS2's, 245/35's up front and 275/30 on the rear. The sizes were suggested by Turner and recommended by Gary. There are no fit issues at all, the steering is very precise even slightly lighter feeling. I haven't noticed any tramming at all. The ride is rougher than the 18's, but it's not a problem.

I have the same combo but with Potenzas RE750 from the Tire Rack, plus spacers front and back and still no rubbing, tracking great, great steering feel, no tramlining and relatively quiet ride. So far I am very satisfied... :thumbup:

Spacers to put the tires at the edge of the well?

Got any high res pics. I am getting the comp pkg and would love to see what that set up is going to look like. :)

I made this size switch, went from the stock Continentals with about 7000 miles (about 60%-70% tread life left) to new Michelin PS2s. My observations:
- smoother ride
- tramlining about the same for large groves in the road, sometimes better if the groves are narrower than the tire.
- upsized tires sometimes tramline in small groves where the smaller tires didn't... but this is rare
- steering feels slightly heavier
- grip seems to be slightly improved... blasting down an on ramp with a turn I can keep on the throttle the whole way with the back just on the verge of breaking loose. Previously on that turn the Contis would start to break loose and I'd have to let up on the throttle a bit. Also, now I rarely break a tire lose from a stop, even when quickly exiting a business with a sharp right turn. With the previous tires it was easy to accidentally break one lose exiting a business.
- initial turn in seems slightly more vague... cuts down on my confidence level in the tires, so generally I don't think I go any faster than with the previous tires even though the apparently increased grip suggests that I might. This really gets to me on the tightest turns of my favorite twisty roads.

If I had to make the decision about tires and tire sizes again I'm not sure what I'd do. I like the improved grip, but I'd like the steering to feel like it has more bite when I crank the wheel. I don't know if the vagueness I experience is more due to a reduction in sidewall stiffness on the PS2s as compared to the Contis, or if it's due to the change in sidewall angles due to the wider tire.

Cheers,
Incendiary

Have you tried varying the tire pressures? You'd be suprised what a few pounds of air can do.....

No, not a whole lot. I'm currently running about the same pressure as I ran in the Contis... about 34lbs up front, and about 36lbs in back. Any suggestions?

38-40 up front would make a huge difference.

I don't have experience with the PS2 but the same pressure might not be ideal for 2 different tires. So just because that worked with the Conti's doesn't necessarily mean it will for the Michelins.

If it were me, I would swap those pressures....36 up front and 34 in the rear, or play with going up and down a couple pounds to see what happens.

And before you say it...yes I know BMW says to put more air up front but they are also the same people who put that tiny 225 front tire on there to begin with.

I bought both sets (15mm front, 12 mm rear) at TurnerMotorsport: http://www.turnermotorsport.com/html/subcategory_detail.asp?modelcode=E46&subcat_id=93

... one caution, though: there is a possibility of rubbing the rear fenders when used with a brand of tire other than the Potenzas RE750 that I have. The same wheels/springs/spacers and tire sizes where used in a M3Forum member ride and he told me that in his car it rubs the rear fenders. I have no rubbing at all in my setup; I cannot remember what brand of tire he was using, but that was the only clearly evident difference between my car set up and his. :confused:

nope, they are the RG4's from RAC monolites.
lighter and stronger than the ZCP or CSL wheels, with a more agressive offset, and they are a bit wider... 10/19r 9/19f.

thanks though, I like them.

Don't know if you are still following this thread, but I have Dinan's 19" wheels (9.5F and 10R) with 275/30F and 285/30R S03's. No interference issues at all. Turn in was improved enormously. After nearly 20K miles (no track) the tires have become noisier and tramline more. I'm going to put PS2's on next week. (Nothing against the Bridgestones, but I'm looking for a softer ride with the Michelins.) BTW I also have Dinan's complete suspension set up including the camber plates. The air pressure discussion raised on this thread will have me experimenting with more air in the front.

On a properly built set of custom wheels, like CCW's that are machined specifically for the E46, you can fit a 275/30 on the front with a 19x10 rim like I have right now, no fender rolling needed if you run some negative camber. You could also go to a 295 tire on a 19x11 on rear, but you'll need to roll fenders

For the track a 275/285 hoosier combo workes nicely on my CCW race classics 18x9,5 and 18sx10.5. A better set up would be to get 4 - 18x9.5 or 10 inch wide rims and with 275 tires the whole way around so you can rotate them. WIth the right back spacing you should be albe to pull this off with no spacer or a very small 5-10mm.

I went to the 2753019 Pilots on the rear and have experenced no ill effects handling in the corners is noticelably better Only problem is now I want wider thiking about rolling the fenders or body kit to get to at least 2952520 or even 3052520

Hey Technik, I have the same dillema as TD330ci. I currently have stock 225/40/19 and 255/35/19 on my m3, but would like to switch to 245s and 275s. What I am concerned about is that if i go with 275/30 the overall diameter of the wheel will come down to 25.5" as compared to 26" stock. If I go for 275/35 it will be bumped to 26.5" and am told that I will most likely need to roll the fenders. Do you know if reducing the OD to 25.5" can be a
problem, especially since my fronts will stay at 26" (ABS, DSC ???). I assume the odometer will be slightly off but I am not concerned with this at all. Thanks in advance.

Hella nice black M you got there! :thumbup:

why?
to increace underateer, which the car has too much of already?

I am running 265f/275r and the steeering is so neutral that it is almost perfect.

I would want to decrease understeer- rather than increase it!

That's why serious track and autocross people are running same size tires front and rear.

20" are pure bling, overall the combos are heavier and the lack of sidewall height reduces the ability to get the tread flat on the ground. Look at F1 cars, or pretty much any other race car, there needs to be some sidewall height to make the tire work best.

And there is a dearth of GOOD tires for thoses sizes.

If you are doing it for looks, fine. But for performance, you are doing the wrong thing.
