Question for M3 guys with 19" who have gone wider than stock.
 
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

:thumbup:

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.

Cowboy Bebop 04-20-2005 09:56 AM

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.

Cool thanks for the info. :thumbup:

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:

Pinecone 04-21-2005 03:38 AM

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

Thanks Pinecone, I think I'll stick with the 245/275 set up. :)

TD330ci 04-21-2005 03:49 PM

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.


Thanks in advance. :)

I'm running 265/35-18s all the way around on my stock 18s.

Sorry for the misunderstanding. I meant what brand of tire and do you recommend them. :)

Toyo T1-S's and they're too new for me to recommend.

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. :)

Cowboy Bebop 04-21-2005 10:47 PM

also running the PS-2's great tire!

Not high resolution pics because of size but at least decent, here you go... http://www.m3forum.net/m3forum/showp...3&postcount=20 :thumbup:

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
