For a product of two rings, the prime spectrum (with the Zariski topology) is the disjoint union of the prime spectra of the factors. Thus, even if one factor ring fails to be Jacobson, if the factor ring with larger dimension is Jacobson, forming the quotient by the Jacobson radical will not change the dimension.

Dec 12, 2015 at 18:38	comment	added	Anderia silva		$R $ is not any special ring in general, such as a product of Jacobson rings.
Dec 12, 2015 at 18:22	comment	added	Jason Starr		What if your ring is a product of a Jacobson ring, such as $\mathbb{C}[x,y]$ and a non-Jacobson ring, such as $\mathbb{C}[t]_{\langle t \rangle}$? Then what do you get for both sides of your inequality?
