URGENT NEED! 8.00 x 16.5 d tires, '88 Class C 21'

I advise to call TIRE RACK for they might have what you need. The people on the phone are very knowledgeable. If they don't have the right tire, they might be able to direct you where to get them. They deliver tires anywhere in the country. You would need to then pay someone local to have the tires mounted and balanced.

I have been buying tires from Tire Rack exclusively for about 20 years now because I mount & balance tires myself as I have access to the right equipment. My point here is, Tire Rack has been very good to me.
