Thanks for the info, brother. I saw that chart but what exactly is it telling me?
And how would I know what offset I would need to fit 295's on there? I can always run spacers but I definitely don't want to be too flush.
So hard to say man. You might be able to stuff a 295 into the rear, but with the front you need to consider how much the front wheels turn too, as far as rubbing. As far as that list, that was my point, seems weird that no one is running that wide of a tire, which suggests to me that there must be a reason behind that. You're right that 3mm is not much difference visually if you used spacers. But even going from a 275 to a 295 is a difference of 0.8" in section width overall, or 0.4" out of the fender, and 0.4" into the fender. Almost half an inch both ways is still a HUGE difference in width. Plus a 295/35 and a 275/35 has a 0.5" difference in diameter, or 0.25" either way. That red car looks almost flush. Going an extra 3mm, and then 0.4", you'll probably be past flush.
Honestly, I don't think there really IS a sure fire way to know if it'll fit. Like I said, the rear is a lot easier to figure out, since the wheel only goes up and down as far as rubbing. With the fronts, they move both up and down, and side to side. Sometimes they'll be moving up and down AND side to side when you're driving and hit a dip, into driveways, etc. Wheel wheels also aren't perfectly round, they have indentations, etc. That is a lot of variables there that could affect rubbing. You also have to factor in that a 295/35 Nitto is going to run a little different in size then say a 295/35 Michelin. Similar to shoes, a Jordan 12 in a size 11 does NOT fit like a Jordan 1 does in a size 11.
If you're willing to give it a go, it COULD work, but know that you'd probably be being a guinea pig, and could run into trouble. It sucks that your car is fairly new, so there probably hasn't been a ton of experimenting going on just yet. So it comes down to if you want to try it and see, and are you willing to roll fenders, deal with spacers, and possibly STILL have a little rubbing, just to get a little extra width? I say do the 275's, as you know they can at least be done, or MAYBE if you feel adventurous, step up to 285's. Unless you feel lucky, then **** it, be the guinea pig, and see what happens. Who knows, you could be the first to do it..... or be the first to see that it can't be done. If you ordered your wheels first, and then got a hold of one beat up and cheap 275/35, or 295/35, mounted it, and then tested that would be a good way to go before buying brand new tires.
When I was into foxbody mustangs, that's basically how people figured out how big they could go in the back, and what width of wheels. Trial and error. People consistently one upping each other, until they couldn't go any bigger, and then someone would break out a big hammer, make the inner wheel wells slightly larger, and went bigger, then someone rolled the fenders and went even bigger, etc.
