Will the computer like 315x35x20

Just a quick question: the only 20" NT05R I can get is a 315x35. Stock ratio is 30%. Will these fit and will the computer like 'em?

I believe the 35s are too tall and will have a rub issue. I am sure others will chime in.

It’ll be too tall. I’m running a 325/30/20 with custom offset wheels. Fits great but it’s close.

Computer will be happy if you increase the fronts, too... but I wouldn't do it, this is going to be dangerously tall (+1.5") for the wheel well, and there isn't that much extra room in the front either. I'm running 315/30/20 in the rear and that's already close.

That works fine as it's still a 30 aspect ratio tire. Body wire harness relocation is recommended.

Makes sense. Flowtie's 305x35x20 must be damn close to rubbing. Their overall diameter is 1.2" taller than the stock tire which means it is .6" closer to the fender well. One member has 305x45x17's on his but the overall diameter is only .4" taller than stock. Overall diameter and sec width are the overriding factors to be concerned with when changing tire size. Thank you for the clarification.

Check the OD (outside diameter) of the tires. The second value is an aspect ratio. A 35 aspect ratio on a 315 width tire is higher than a 35 aspect ratio on a 305 width tire. Check the OD of the tire. Tirerack has measurements for most any tire. Choosing a tire with same OD will lend itself to less fitment issues.
