Rolin Sinn

Shopped around for pricing and Kustom came in lowest. Called me as soon as they were in and got them on 2 days later. They ensured my alignment was correct with bigger tires and gave me all the info to ensure my torque specs were good after a few days of driving. Rims and lug covers don’t have a scratch on them.

Jake Kidman

Fantastic find! On our way across country and had tire problems on a 36 foot trailer and these guys had the space and equipment to get new rims, tires mounted and balanced and back on the road. And they did it quicker than any other tire place I've ever been to! Highly recommended, thanks gentlemen!

K Nels

Very professional company the entire way through. Owner and employees are very respectful and easy to work with on job sites. Very quick to respond and do a high caliber job. Will hire them for all our concrete pumping and dump truck needs.
