How much is 35 sidewall in inches or a 40 sidewall?
It matters on the width. The sidewall number is a percentage of the width. Let say you have 265/50/15 the sidewall would be 50% of 265.

So basically 275/40/20 is taller or thicker in sidewall than a 295/40/20?
295s would have a thicker sidewall because the percentage stayed the same.

No, the math is correct. 235mm * 0.5 is your sidewall height, or 117.5mm. Convert that to inches, double it, and add you wheel size and you end up at about 27.25" Remember that the tire size measurements from the manufacturers are nominal. Just because they *say* it's a 235mm wide tread, the actual tire will vary from that somewhat.

Doing the math again, your 295/35-20 would have 103.25mm sidewalls or approximately 4", so a 28" tall tire. The 275/40-20 would have 110mm sidewalls, ending up at 28.66" total height. Make sense now?

Yes, my question would be if i do an inch drop on 295/40/20, would i rub or should i go 275/40/20?

Now that I can't help with. Though I would ask how wide the wheels are. I'm guessing 10"? If so you are good for those tire widths.

No its more about the sidewalls, i know the 275/40 fits fine, a lot of ppl have it, but the 295/40 are an inch thicker
