This is probably a dumb question but what dictates the tire pressure you should set your tires to? I only ask because I just got some new Pilot Road 4s put on last night and I asked them what they set the tire pressure to. They did 36psi in the front and 39 in the back. My 09 Versys manual calls for 32 in the front and 36 in the back. I think it says that on the swing arm too. I asked the dealership why they set the pressure that high and they didn't have an answer. I'm just looking to get the most life out of my tires and proper tire inflation is key is pretty important. Not sure if it helps but I'm a bigger guy, 250lbs and I have saddle bags on the bike. Maybe they over inflated to compensate? What are your PR4s set to? I appreciate the feedback.
