I think most tire manufacturers want you to run at least a 10.5" with 305's.
On the forums some will say they will work, while others will say they are too narrow, I say best to go with what ever the tire maker recommends.
I'm pretty sure that most mfrs and the T&RA consider a 10" wide rim to be the minimum for 305/35's (in any wheel diameter). Keep in mind that relatively narrow wheels (like this proposed setup) will allow greater amounts of lateral tire distortion while cornering.
The "measuring width" for 305/35's is 11". Just saying . . .
It would be very close and id bet youd rub with that much lowering. It also depends on the wheel offset. I wouldnt risk it though if you want to stay lowered stick with 295s (those SHOULD fit, but still depends on wheel offset). I had to raise the rear of my car back to stock height to fit the 315's.
305s did fit fine with steeda sport springs i believe, if i remember correctly.

I would definitely do the 295 if the cheaper tire brands would offer that size! Preferably the nitto invo or the nt05

Thanks, Norm. Can you clear up the idea about tire distortion for cornering on this narrow rim? I'm now picturing the excess tire distorting upon corners; I never took this into perspective. Would it not benefit me running a wide tire in relation to my rear end being more 'planted' around corners? Or would it do more harm than good?
Better a picture than a thousand words . . . from Paul Van Valkenburgh's "Race Car Engineering & Mechanics". Kind of extreme, but all tires behave similarly (just to different extents depending on lateral g's, wheel widths, tire construction, etc., etc.).

Norm, I'm sure you wouldn't recommend spacers either, after google searching your name and 'wheel spacers.' I am a big fan of my handling, looks like I should go with a wider rim if I want a wider tire.
So would you recommend just sticking to my original setup, the 285/35 on the 10" rim?

Yes.
I'm not against the use of very thin spacers to solve a minor rub - the right front of my car gets an 0.025" spacer when the 18x11's go on for that very reason.

Yes. You should be able to make that work at both ends of the car and still be rotate-able front to rear.

Anyone running 10" 305/35-19? Clearance questions
