My track jarred me over bumps, I noticed by the tire inflation gauge that my tires when heated gain about three lbs. pressure, so I run 31/32 lbs cold and when my tires are heated they get up to recommended 35 libs and my car rides much better

 

The 35 lb recommendation is for cold tires. Running them lower will soften up the ride a bit, but at the expense of handling. Also, underinflated tires are subject to uneven wear and overheating when run at speed, but 3 lb shouldn't make a lot of difference. Monitor the tire wear on the outside edges for underinflation wear.

 

you are 100% correct, I filled my tires to 35lbs cold
