I just picked up my tires that I bought from FWP today. Now I just gotta get some rims. Here they are 5 37x12.5x15 MTRs And here is what they are waiting to go on. If any thought "Hey can you fit 5 37x12.5 tires in the back of a K5 and still use the Rear seat?" Here's your answer. It was not easy to get the gate shut and it was even harder to get it back open.
