20" Tire sizes

Size (width) of a tire depends on a width of a rim. I have 295/30/20 rears (on both Vulcan and Vortex rims).
You can easily try increasing side walls but bear in mind maths. 30 means 30% of width. So for your 285 (rear) it is 85,5mm vs mine (295) 88,5mm. 35 will make you close to 100mm.
The widest is XKRS GT with 305 tire. But I'm not sure if it is 305/30/20. If so - going to 285/35/20 would increase a size of a wheel by less than 1cm over XKRS GT.

Yes, you'd need another inch to use a 305 tire. I'd prefer 315/25. Doesn't matter the ratio, but I've got this all figured out if I can find someone to make them for less than $2000.
