especially with a low volume tire like the 1.95 Ignitor. Most bikes have a slightly rearward weight bias, more weight over the rear wheel than the front. If you're not pinch flatting in the front but are in the rear running the same pressures, then you need to add a bit to the rear. With low volume tires on a hardtail I usually run between 3 and 5psi more in the rear. With higher volume tires or on my FS bike I can usually run the same pressure front and rear without problems. So take the rear up about 5psi, it should help.
