Tire sizing hre

e90m3japan · 10-28-2010, 03:42 PM

I got 19inch HRE P40s, that are 19x9et28 and 19x10.5et28 and have ps2s on them. Right now they are 255/35 and 295/30.
I was think of going to upgrade to 265/35 and 305/30, will they fit?! And are they better performer than what I got?!
Any suggestions or advice I greatly appreciated.
Thanks!

255/35 and 295/30 is perfect in Michelin PS2 or Advan AD08 since the tires are "bubblier" to begin with. The size of the tire widths are a measurement of the "bead" or "rim width" and not the actual overall width. The PS2 and AD08 have thicker overall widths versus other tires so the physical width is closer to a 260/265 front or 300/305 rear. I hope this makes sense.

I have run the AD08 in the 265/295 setup on a friends car with fender mods. The amount of necessary fender work depends on the offset, car height, and alignment.

Performance is completely dependent on how you drive. Usually wider is better, but you have to try it out yourself...

Hope this helps and makes sense!

Thank you.
I really see what you mean, but I was thinking of going to upgrade to same Michelin PS2s with size 265/305set up.
But might not be a wise choice since you gave me this advice. But you know I like the sound and look of the 305s.
