Sizing suggestions on CH-R 19"

PunjabiM3 · 04-05-2010, 09:23 PM

Well I have decided to be simple and go with the one piece CH-R wheel in 19" sizing (had 20" Klassen before). I am going to get the silver finish and have tire sizing down to 255/35-19 front, but on the rear I am torn between a 285/30-19 and 275/35-19. Which of these sizes would you go with? The 285/30 has a smaller diameter than the stock 265/40-18 and the 275/35-19 has a larger diameter. I assume the 275/35 would be better for the speedo inaccuracy correct? And is the 275/35 too narrow for a 10.5" wide wheel (don't want it to appear stretched)? Thanks!

255/35/19, 285/30/19.
Front is taller, rear is shorter but I believe that is what more aggressive M3 uses from BMW (M3 GTS?).

275 is not enough tire on a 10.5 wheel.

rzm3 · 04-06-2010, 09:44 PM

yup 275 will be quite stretched... tried that in person...

Why not 295/30?

carbonbmw · 04-07-2010, 03:45 PM

Thought about it but it will only induce more understeer and the 295/30 weighs around 1-2 lbs more per tire. Doesn't make sense for my car unless of course I was to have FI.

I think 255 front, 295 rear will feel great IMO. Also look great too.

If you feel uncomfortable about that, go at least 285 in the rear.

I will likely be going with a 285/30-19 for reasons I stated above, not to mention there is a greater variety of tires in that size than 295.

245/35/19 and 285/30/19 are exactly the same diameter wich will look perfect.....just my 2ct

I ordered the same wheels and looking for tire combos. Can I use 285-35-19 rear tires on stock suspension ?

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
