Has anyone put taller tires on their 3? My goal is a smoother ride and lower RPMs while cruising on the highway. My Enkei's are 6 lbs lighter than stock, so I am not too worried about the extra weight from larger tires.

I am thinking about going from the stock 215/45r18 (25.6in) on 18x7.5 +42 to 215/55r18 (27.3") or 215/50r18 (26.5"). Figuring it will work since some people have 225r45r18(26.0") while lowered 1" to 1.5" without any issues or rubbing.

Maybe I will find a used tire place to try the size for cheap before investing too much into them.
Here are relative comparisons. 3s shown are on Tein HTech springs.
Stock 18s
225/40/19 wheels are 19x8.5 et45
19x8.5 et45 w/ 235/40/19

Just changed my wheel setup to 19x8 +40 on 235/40/19. Rubbing in the rear on turns. My fenders are rolled but not flat. Going to need to tweak it a little.

That'll be a quick, easy tweak.

Well, relative to 19x8.5 et45, your fitment has about 5mm more poke.....the source of rub.

I’m also on corksport springs. Pretty soft. I’m rubbing on the fender liner itself as well under compression.

Hi.
I'm reading awhile this thread.
I want to put on my M3 18x8.5 ET 40 with 225//40/18 tyres.
Is it possible without fender roll.
I'm not sure any more.
Stock suspension.
Thanks!

18x8 +46 235/40/R18 Mitsubishi Galant Rims, Stock suspension, ebay aero kit.

Wondering if anyone has experience with running 3/4 inch(20MM) spacers on a 18x7.5 +50 rim. They are for summer tires and sit about 10mm further in than the picture. Did you have to roll your fenders?

Im planning on lowering with eibach prokits in the future but want to avoid rolling since one of the rear fenders has some body filler in it.

When I had eibach on stock 215/45 18x7 +50 and 15mm spacers I had to roll the rear. Rubbed on dips at high speed. But not too bad.

Dear All,

Is the Jr21 215/45 r18 8.5J E.T40 fits under the Mazda 3, which has 30/30 Eibach (KBA91451) ? Does anybody have pictures with similar parameters?

Thank you in advance!

8.5 et40 cuts it really close. The 215 could clear rears with its stretch. If you'll get some slight rub on dips & load, just roll rear fenders or grab rear adjustable arms to tweak camber.
