The size 110/100-18 tire will fit just fine. This tire is only 10mm wider, and 10mm taller than the 100/100-18 tire.

I am not trying to be negative, but I fear the shipping costs for those tires is going to be very high. The rear tire probably weighs at least 12 pounds, the front tire probably weighs at least 9 pounds. The shipping information page at the Taobao Trends website is currently showing an error.

However, I estimate you would pay about $120 in shipping if you bought both of those tires. I'm confident you will get a much better deal, and faster shipment, if you purchase Shinko or Kenda tires from a reputable, online vendor in the United States.

It's best to purchase lightweight items with small volumes when shopping at Taobao.
