Sorry i dont have access to my computer right now. I am at my shop.

I did make some hand writing (sorry my writingis pretty bad) for the same analysis requested.

So the difference is 2.22 % between the stock rear roiling diameter to ur intended size spec.

But please be aware this calculation only to measure how u will be close to the setting from the manufacturer. Does not mean that u will not enjoy different setting with different tire sizes.

Some engineer could argue that 1 % difference is too small to judge the boundary to calculate whether it will give stress to the electronic and mechanical features controlling vehicle driving dynamics.
