Narrative:
I was pilot flying. At rotation we felt a small vibration/shimmy; I thought perhaps due to a gust of wind. We took off and began the normal climb out sequence. After raising the gear; we noticed a red light and green light in the gear indicator system. We continued our clean up and got a vector south and climb to 7000' MSL. The pilot monitoring got the QRH out and looked for a checklist for our situation. We still had good hydraulics at this time. I stated the right main was still down per the green lights and the red light was on due to the gear handle being up and the gear being down. We noticed the a system hydraulic quantity decreasing and eventually go to zero. We ran that checklist and coordinated with dispatch and the chief pilots. We elected to do a fly by for the tower and they confirmed a blown number 3 tire; number 4 looked good. After further consultation; we elected to do an overweight landing 131;000 lbs considering crosswind; weight; stopping ability; and only one main on the right side. The captain elected to make the landing. Upon landing the hydraulic annunciator flickered and I noticed the B system quantity at zero and rising. We slowed near an available exit and the system was at 45%. Tower asked our intentions and we cleared at there and told them we were developing a dual hydraulic system fail and would stop in place. Fire met us. We shut down the engines; had it chocked and were towed back to the gate.

After further consultation; we elected to do an overweight landing 131;000 lbs considering crosswind; weight; stopping ability; and only one main on the right side. The Captain elected to make the landing. Upon landing the HYD annunciator flickered and I noticed the B system quantity at zero and rising. We slowed near an available exit and the system was at 45%. Tower asked our intentions and we cleared at there and told them we were developing a dual hydraulic system fail and would stop in place. Fire met us.
