Tire Information

After reading the article in Rider Magazine about Darrell's experiences with the Dunlop RoadSmart IV tires https://ridermagazine.com/2021/02/13/dun...1587389F7S, I once again compared the prices of the RS IIIs with the IVs on RevZilla.com, and wondered if the IVs are really worth the extra money over the IIIs. I wondered if the extra mileage (based on Darrell's experience) really made them worth the cost. I decided to do a comparison that would take into account all the factors I could think of. I decided to compare the cost of the two models of tire over 100,000 miles. Here is the result, in terms of both dollars, and my time to get the tires changed:
   
I used RevZilla's current prices for the two sets of tires. My installation cost is $100.00 per set if I take only the wheels to my local installer, MCC Motorsports in Villa Park, Illinois. I used Darrell's average mileage over nine sets of RS IIIs, and his mileage for his first set of RS IVs. At those averages he would use 12.8 sets of RS IIIs to go 100,000 miles, but only 9.8 sets of the RS IVs. As you can (hopefully) see in the image, the RS IVs at $4,419.62 are less expensive for that distance than the RS IIIs at $4,500.13.
I also estimated my time cost to get the tires changed. The difference is significant.
One thing I did not take into account is (based on Darrell's assessment) how much better the IVs are than the IIIs.
I've attached my spreadsheet in case anyone wants to tweak the numbers for their own amusement.
