Who's run 285/30, 10X18, on a NB?
Follow-on to my BBS order dillema, looking for input and actual experience. Besides "Do they fit",
1. What tires did you use?
2. What was the wheel offset?
3. How tight was the fitment, both inboard and outboard?
Thanks guys for the input.
Best,
Matt

I did it with MY02s 18x10 et65. The tires were ContiSportContact 2s 285/30/18. I had slight rubbing if I hit certain dips just right (wrong.) The outside of the left rear tire rubbed on the inner fender flange. It never damaged the tire, and it was hard to see where it was rubbing the fender.
My car is lowered to somewhere between RS and ROW ride height. I don't think it would have been a problem with the car even slightly higher. It was also only only the left side where the body is closer to the wheel by a couple of millimeters than the right.

I run 285/30-18 Summitomo HTRZIIIs on the OEM, 18x10 (65mm offset) Hollow Spoke/Technology wheels. I also have the car lowered (H&R springs/Bilstein HDs). NEVER had any rubbing, even during a couple auto-x events.

MY02 with Michelin Pilot Sports. Ride height approx. RS +5mm.
No rubbing but my fender lips were rolled by the PO. Note that 285/30 is just a little shorter than the 265/35 so this helps mitigate some of the rubbing potential.
For the record, I would not hesitate to put 295/30 on except that I prefer the handling balance with the 265/35 on the rear.

My track wheels are 8" et 52mm and 10" et 65mm hollow spokes shod with 235/40 and 285/30 Michelin Sport Cups. My car is lowered to 10mm above RS or 10mm below RoW Sport (is the glass half full or half empty - it's the same) My camber is -2.5 front and -3.1 rear. I have not experienced any rubbing at the track. Clearance does look close in the rear on the outside of the tire and inner fender lip. I imagine there would be rubbing if I didn't have such aggressive camber.

The appeal of the 285 is the shorter diameter and lower gearing. Why run a 265 and make already tall gearing worse?
Intended use is 10-15 track days per summer and spirited drives.

I am running 225/40/18 and 285/30/18s on my car. Tires are Bridgestone RE050A Pole Position. With the Pss10s, I have almost too much grip, and not enough power to have fun:-)
Upon installation, the left rear would slightly rub, if I hit a really bad dip on the road. It happened every other month in LA:-(
(I have almost no negative camber and non-rolled fenders either)
I solved the problem by stiffening the shocks (7 in the rear).
I tracked the car once at Streets of Willow, and it never rubbed, even under heavy cornering (M030 sways). The handling was superb.
I like the perfect flush look too! The rims don't stick out at all.

Stick with stock offset and 285 will fit perfect. My old car had RS Speedlines and stock (non-rolled) fenders, ran S03, Pilot Cups and Race slicks (all 280-285) with no problems. Current car has agressivly rolled fenders and I run an 11in rim with 285 or 295 without issue.

This thread is a good reminder that 993s are hand-built cars to a large extent. Each one has an ever so slightly different set of tolerances and dimensions. If your car is lowered, the only way to see if these tire widths will rub is to try them. It looks like the odds are pretty good you'll be fine.
