295/18/30 tires are rated for 10-11 inch wide rims, 11.5 is considered "stretched" buy the manufacture....

But the follow up answer would be a 295 isn't going to fit up front with DF fenders no matter what rim/offset width you choose to run them on. If you are on 18" then max safe/functional fitment to clear inside and out would be 275/35 on a 10.5" wheel at + 50 offset. Keep in mind this is a taller then stock tire. 25.6-25.7". 285/30 would be the optimum size overall, however I cant in good conscious recommend it with out risk to the outer fender. Its not like these are steel where you can just fudge a bit and pull them some more out of the way and live with a little rubbing. Fiberglass doesn't give at all, they crack and break the first time you get it wrong.

On an 18" wheel 11" would be optimum width for a 295/30. 10 would be pinched. if you are going to invest in wheels, get the best size that maximizes turn in response and grip. 10" wont do it, doesn't matter what the manufacture says is within safe margins. And for what its worth, Kuhmo XS (now discontinued) made a 295/35/17 that liked being on a 11.5" it was the max recommended width for that tire. Always aim for the widest rim to tire section width to get the most out of the tire. 295mm is 5mm off of 12". 18's have a shorter sidewall and less give, and therefore don't need the same level of rim width/pre load on the sidewall to get the most out of it.

how does the evasive motorsports s2000 make this fit with voltex 25mm fenders ?

For the sake of these Yokohama 285's specifically, they are a lot taller diameter then stock s2k sizes at 26" -half inch taller) Not sure why those decided to run a 35 series, other then there either weren't any good compound choices in 285/30 or they intentionally wanted the gearing change to match their engine output being boosted. Something to keep in mind though if you are planning on rushing out to get this exact set up. You will also need to account for even less suspension upstroke/ride height room going this large a overall diameter. But again if it were me, id just assume find a good compound proper width 275/35 which would likely be wider then these 285's and run those, either on a 10" or 10.5" if you want to maximize the tires available contact patch. Tire will be shorter at 25.7" too. Still taller then stock, but reasonable.

Based on the pics, these tires clearly run narrow. I've seen 255's on 10" wheels have as much sidewall profile. Tire width discrepancy between manufactures is the only way your going to fudge a known fitment standard. Its why I was able to fit a 315 out back without over fenders and only about 3mm pull on the fender because the particular tire runs about 10mm narrow. Id never recommend that to someone though, requires too much trial and error, with the emphasis on error. If you are willing to get under the car and get dirty and explore in detail like I have on what can be fit at different ride heights and alignments and rim width/offsets and tire width combinations I fully support that, this is always what it takes if you see a crack of light coming through and want to try and exploit it.

reason why we can make it fit on our car, is because we are also running downforce front fenders (+30mm) as well as the voltex over fenders. which essentially gives us around 50-55 mm more clearance over stock. anyone that has ever ran Yokohama AD08R knows these tires do not run small. they in fact run wider basically one size up.

Visually all I can go on is what I see in your pics posted, and the profile of that tire sitting on the 10" wheel makes them look narrow for a 285. I know the 255/40/17's run pretty wide. You ever compare them to the width of these 285's side by side?

There you go then! You could easily run a wider/lower pro 295/30 if you wanted. What's the reason for running a 35 series anyway since you are chiming in?
