So there is room for a little more rubber on the rims. Does that play any risks? I wouldn't mind a little more rubber on the road, especially in the rear.
It is a very commonly done thing with the stock rear 10.5 inch wheels as people look for more contact patch. I would say you should consider as to why I would choose not to do it personally. You end up adding more to the rotational inertia especially more weight on the extremities of the wheels. Usually the further the weight away from the point of rotational force, the more it will impact the response time. For example, if you add 2 lbs near the center (hub) of the wheel, it will have far less impact on acceleration/braking than say, adding 2 lbs per wheel on the tire since it is furthest away from where the rotational force/torque is being generated.
so get the 35 in the rear on that 295? Or take the front back to a 255?
No, the 255 mm or 295 mm is the width of the tire. The second number 30 or 35 is usually the percentage of the width that represents the tire wall height. So 295 x 30% = 88.5 mm for tire wall height. Stock tire wall height is 275 x 35% = 96.25 mm so you will end up with just over 7 mm of less tire wall height in the rear compared to stock. You might have to go 295/35, which means 295 x 35% = 103.25 mm for the tire wall height. So, you might end up getting a more chunkier looking tirewall in the rear and a more raised look.

yup thats what I was asking. Go 295 35 rear. But im good with 265 35 fronts, right ?

Yeah, you should be fine with that. You will have more contact patch and some chunkier sidewall at the front as well since you are increasing the tire wall height. More contact patch both front and back for more ultimate grip. Although, it will add about 2-3 lbs of weight per corner due to the added rubber.
I went with A/S tires because where my RCF is located, the ambient temperature drops to low 20's and below. Not much snow/ice though.
So far EXCELLENT grip. I noticed also that with these specific A/S tires there are EXTRA "ribs of rubber" at the point of contact with the wheel to offer some protection against curbing the wheels.

Were you putting those 295 rears on a stock rim? Or were they aftermarket. I would mind putting that on if I could, but you got me thinking now with the side walls. I don't want to change to much from the stock setup, that's why I thought 265 F and 285 R wouldn't be that much of a change, and grab a tad more width.
I thought about doing 295 on OEM WHEELS. But decided against it. As I remembered either the Michelin PS A/S 3+ did not come in that size or out of stock back in October/November. Plus I thought the 295 for the rear will be "too tall" and will look "funny" and probably not safe since there will be some "weight" transfer towards the front. The front is already got "more percentage weight wise".
If I had gone with 295 for the rear, then I would have to increase on the fronts as well to keep it all in "balanced" front/rear.
I have noticed a slight MPG drop lately. I don't know if it was my new tires setup OR the new full cat back Borla exhaust system? I had both put on at about the same time and then I flew out for a trip and now just getting around driving my RCF. My guess is my new Borla exhaust system causing me to hit the gas paddle more!!!! And hence the decreased mpg!!!!😁😁😁😁😁. I just can't resist the Borla crackles and pops every time I shift!!!
