Tire width with Eibach springs, 19 oem wheels

I did some searching but didn\'t find much.. I\'m looking to replace my oem PS2\'s and want to widen them as much as I can without rubbing. These would be for street only... I currently am running a 10mm spacer (front and rear) on Eibach springs.

I\'m looking at the Pilot Super Sports ad the replacement.

Can I go with a 255 front/285 rear? Would the 10mm spacers still work?

You could go with a 255/35/19 front and a 285/30/19 rear with no issues.

Eibachs clearance is just a few mm from stock so rubbing won't occur unless you go lower.

No rubbing issues, but those tire sizes would cause some dsc sensitivity issues as the car prefers to keep the front diameter slightly less than the rear. 285/35R19 is actually 1% shorter than the fronts. Given that

255/35R19's front and 275/35R19's rears are plenty for OEM wheels. He said street only so I'd think DSC would be good to keep working right

I dunno about tire clearance, though. Someone should comment whether the drop+spacers would cause 275/35 to rub. Seems like it isn't too much of a change.

I'd really like to go with a 285 in the rear... Will those rub with the 10mm spacer?

Agreed, this is something I am experiencing right now but its not a big deal. I find the DSC more intrusive than it being dangerous. It shuts things down more quickly, when I want to drive like a hooligan I just turn off the DSC.

Does putting it into MDM "M" mode help with this? I would think that would help when driving aggressively.

Yes, because MDM lowers the intervention point. However, it is still going to be more intrusive in any mode than it would with a stock front/rear height ratio.

255's front with spacer have caused rubbing in a couple of cases, but not always and not too severe. Alignment setting and variance from one car to another are probably what makes it hit or miss. At worst, you'd need a camber change or take out the spacer.

Thanks Ben....I have fairly narrow spacers for the front (10mm), so maybe I will be OK.

Which OEM wheels are you running?

I don't think you'll have any problems running 255/285 PSS on Eibachs with 10mm spacers all around. You MIGHT have a problem in the rear but if anything I'd take off the rear spacer and just run one up front.

You might need to run some camber though. Let us know how it goes!

What's the biggest rear tire you could use on a oem zcp rim lowered on dinan springs I don't see a need to widen the front tires and I don't want to use any spacers?

**EDIT 10/25/11*** With the 285/30/19 rear tires on the factory rims I would not recommend. The tires DO NOT rub however they are a little too wide fo rthe rim and I experienced a stability problem in the rear. Car would feel like it was swaying while on the highway...Almost like I did not have enough air pressure in them... I tried 3 diff tire manufactures, many different tire pressures and all gave the same result
I spoke to a few shops and they said the 285 tire overhangs the factory rim and the sidewall flexes.. So I now have 275-35-19 coming and will update you guys on this!

Cool....looks good. Do you have any pictures from the rear of the car showing what the 285s look like (width)?
