As for tyres, I ran McCreary crossbar military tires in 7.00 x 16 on my series for about 12 years. Finally picked up a set of used CoOp GripSpur 7.5 x 16's and have been running ever since. Are they loud? YES! Do they suck on wet pavement? Absolutely! Do they go off road? YES! I finally made a trek into town today and stopped at the garage to get fuel and check the tyre pressure, I had 0 psi, 8 psi, 16 psi and 0 psi. Would have never known. These tyres are so stiff they look and act the same with 0 psi as they do with 35 psi in them. As for tyres, just make sure they match your needs. I'd shop around and have them shipped to you once you find what you need.
