Need help finding the right size tires

[Davidnguyen204]

Hey guys. I bought a used set of apex EC7R in 19x9 et 30 fronts 19x9.5 et 22 rears. What is the max tire size can I run with these wheels without any rubbing? I was hoping to run 265/35/18 front and 275/35/18 or 285/35/18 rears. E90 on stock zcp suspension. Will these tires work or should I go different sizes? I may need to run spacers to make them more flush. I’m currently running zcp wheels 255/35/19 and 295/30/19 without any rubbing. Any advice would be appreciated! Thanks guys!

The 19x9et30 is close to 18x8.5et29 stock wheel, it’ll actually have the wheel pushed out 0.20” relative to stock. The lowest rim width for a 265 mm tire is 9.0” but it’ll have a pinched look because the section width is 0.7” wider than the rim width. A 9.5” wheel is the ideal size for a 265 mm tire. So a 265 theoretically fits a 9” wide rim but will have a pinched look with a 0.35” overhang on both sides. The 265 mm tire on a 9” wide wheel is right at the practical limit but be prepared for the pinched look. FYI, putting the widest possible tire on a rim doesn’t usually produce more grip. However, there should be no rubbing issues but you could add a 10mm spacer if there is inner clearance issues and you’d still have no outer clearance issues.

The 19x9.5et23 is the same as the stock rear wheel. If you wanted the rear to match the front you’d want to run a 5 mm spacer but not required. A 9.5” wide wheel fits within the 275 mm tire’s recommend rim widths but with a 9.5” wide rim the tire section width is 0.4” wider than the rim width. The 285 is even wider and the tire is 0.9” wider than the rim - 0.45” overhang so it’ll have a really pinched look. The 275 should be fine for both inner and outer clearances but be prepared for a slightly pinched look. You could add a 12-15 mm spacer if you’re using a 10 mm spacer on the front. I would not recommend running the 285 mm tire on a 9.5” wide wheel. The ideal tire width is 265 mm for a 9.5” wide wheel.

Could you post a picture of your 295/30/19 on the stock wheels? I’m thinking about going up to that size with mine and was looking for a picture to reference the fitment. Thanks

M3SQRD do you think 255/40/18 up front and 275/35/18 rear will fit nicely? Or would you go 275/40? The 255/40 is 26” tall, 275/35 at 25.6 and 275/40 are 26.3. I’m assuming it might look better if the rear tires are taller then the fronts? Any other tire combinations where both front and rears are closer to each other?

04tl if you pm your number I’ll send it over. Haven’t figured out how to post photos quit yet. I personally love how wild they look from the rear. Does have a slight pinched looked as mentioned above haha.

Either one will work so I guess it depends on whether you like meaty sidewalls which I do. I’d also go with the 275/40 because it’s a 1/10” closer to matching the F but it’s just a 1/10”.

275/40 done. Thank you so very much!
