I run 255's on my front wheels which are 9.5", and like Brad said there is plenty of room for them. No rubbing in the 7 -8 years I've been running that size up front. But they are a bit too stretched for my taste, so I plan to switch to 275's up front, which is about as wide as I can go on the 9.5" wheel (maybe 285's but I'll start with 275's - baby steps ), sometime in the near future.

Now that I have 295's in the rear with vastly improved handling, I do wonder if I'd be taking a step backwards in that department. Lighter but less tire patch.

Yup, good call, they are for the Porsche.... It's up on jack-stands right now getting a whole new suspension (I mean everything!), big front Brembo brakes with 2-pc rotors & braided lines, new rear brakes, new tires, etc... I was also able to find a pair of 245/35R18's in the same tire locally for the front. They were also a good deal, but not as cheap as Tire Rack has them for.

Forgot to ask.. Are the 285/40's the ones you are running on 9.5" wide wheels? I was a bit worried that the 285's would be too wide for my Porsche wheels (also 9.5"), but after seeing your pics and seeing (and measuring) the tires it looks like a 9.5" wheels is just about right for the 285.. maybe a 10" wheel would be ideal, but the 9.5" is pretty close to perfect.

Yep, they're on the 285s, it's a bit funny since my front 245s are the narrowest tire width recommended for that 9.5 and the 285s are the widest tires recommended for that width wheel. I've ripped around a bit so far and they seem to be holding up well, and the grip is really good. It seems that a 10.5 is the "perfect" mount on that 285 but I'm happy with the fit.

Would 11s fit in the back with 295s + stock camber lowered? Offset is not a problem (wheels I'm thinking are +55). Other option for the wheels are 10s but I'd rather go wider. I like the safely stretched look.

His is RWD, and his build thread here for specifics~

My rear wheels are 10-1/2" with a +37 mm offset and without my spacers I only have about 1/2" of clearance on the inside of the wheel, so I'm not sure a 10-1/2" wheel with a +55 offset will ever work without spacers.
Keep in mind, though, you'll definitely need to run quite a bit of negative camber (or heavily stretched tires).
Here's a handy dandy wheel offset calculator that will help you determine offset/clearance based on tire size. Based on this calculator a 295/30R30 on a wheel with a +55 offset would be about 0.9" closer to the suspension than my old set up which was a 285/30R20 on my wheels with a +37mm offset (which as I mentioned above didn't have nearly this much clearance).

I'm in the market now for some new rubber on all four corners. I've got the stock duckfeet sport wheels. What is the absolute most meat I can get away with? Stock suspension as well. I'm in Texas so I'll also be buying some hardcore summer tire. Maybe YOKOHAMA or TOYO
