Back in March of this year I posted a question on this forum about how to use a car tire on my 2005 C10 sidecar rig. I got several good suggestions about adapting a different wheel to a C10 and referrals to other websites. But, the best and easiest solution I finally found was to just use a 175 - 16 tire on my stock wheel. It seems like there are not a lot of 175 tires for a 16 inch wheel out there, but I found a Goodyear Assurance Fuel Max 175/60 -16 that mounted right up on my stock wheel with plenty of clearance between the swingarm. Again, I am pulling a sidecar on my bike but so far I've put over 4,000 miles on this tire and it is doing great. I notice hardly any wear on it so far. I paid right at $200 for the tire and it has a 65,000 mile treadware warranty. Sidecar rigs tend to be harder on rear tires, but If I get even half of that out of it I'll still be way ahead of a motorcycle tire.
