tire question- firestones and will they fit?

[sbaugz]

Hello,
Was looking to start building my brat style build based off my 81 special. I am using the stock mag wheels - 19" front and 16" rear. I was leaning towards the 5.00-16 firestone on the rear and the 400-19" on the front. Does anyone know if these will fit inside the stock swingarm, the forks and front fender and between the frame in the rear?

The 5.00-16 is just a slight bit narrower than the stock 130. The 130 is 5.11 wide.
A 4.00 is just bit wider than a 100. the 100 is 3.93 wide.
So, yes they will fit.
