How to get "meaty" look on OEM wheels/tires

Anyone know how to get that "meaty" tire look on OEM wheels? I know tires differ on design which can affect the appearance of width to the tire. I see old M3's (e36) with factory 17's running what I believe to be stock tire sizes but the tires look wider and meatier (is that a word?) than e92 M3 stock tires. What gives??? Are wheel spacers the answer here? Or can changing tire brands give a wider look without changing tire sizes? I know we can go up to about a 275 in the rear without affecting performance, but that's not going to be much wider than the 265's. So, is there another solution (besides getting wider wheels and wider tires)? Thanks.

Spacers will increase the track stance giving it a wider track look.

Thanks. From what I'm hearing Spacers are the best bang for the buck to get that meaty look and still have OEM rims.

Spacers, and 245/35/19 front, 285/35/19 rear.

If you have 18's, get spacers as well. Putting my 15f/12r on by next week along with Remus race. Il post pics up from the rear. Will DEF look meat-ier:lol:

to add more to this- spacers are a great start but tires also make a huge difference.

you can always go 10mm wider tread width or a taller aspect ratio i.e 265/35 to a 265/40- that gives more sidewall 'bulge' so to speak and looks meatier.

Also, not all 265mm tires measure the same, some tire companies make a narrower 265mm and some tires companies make a wider 265mm tire.
