Satisfactory transaction. Competitively priced tires.

all items showed up in different packages with one tracking number for 3 separate packages

My "new" tires are over 8 months old per the manufacturing date code. Since trailer tires are supposed to be replaced every 6 years based on date code, it would be nice if they were less than 6 months old when purchased. Thank you.

Easy to order and affordable price.

Prompt service, good pricing and delivered in good shape, no damages. Thank you!
