In addition to selling and repairing used and new tires -- we are perhaps Kansas' largest used tire retail store -- we are also Wichita's premier outlet for nitrogen fill for your tires! 7-10% better fuel economy that translates to about $.30/gallon savings or more; 40-50% longer tread life; and reduced environmentally harmful emissions are three good reasons to fill your tires with Nitrogen! We also do oil changes and most automotive maintenance and light repairs.
