Steve does rock solid work at a great price.
I drove to his store.. not sure what was wrong with my car at the time
I just knew that there was a noise coming into my car with the windows open or closed.
it sounded very loud.
Steve test drove it in less than 30 seconds identified the problem..
It was a left front hub and bearing.
My car came in limping and in less than 2 hours later ..magic
I was 100% impressed with the work done.
Give his shop a chance..
You won't be disappointed

They replaced my back brakes and rotors and I will never go anywhere else! They are kind and fast. My car was in and out within no time and I was back on the road. Thank you Diagonal tire!

Steve at Diagonal Tire & Alignment fixed a problem that I’d been trying to get diagnosed and fixed for months. He was incredibly helpful and knowledgeable, took his time and did an incredible job. He explained everything to me they he did as well. Give him adequate time to get the job done right and the results will be worth it! And be wary of 1 star reviews given by ones that previously gave 5-star reviews.

Steve and Ken did a great job on my 81 Vw rabbit pickup. Went to 3 different alignment who tried to upsell me on parts I had already replaced. Steve is a straight shooter who will get you in and out for a great price. I saw benson Whitney’s review on the wall and thought it was kinda weird that he changed his original review after saying they already did a good job. You’ll never please everyone and Steve is someone you can trust.

I had a flat due to a nail that wasn't close to the wall of my front tire but every big business tire shop said that they couldn't patch it cuz of too close to my wall and i felt that they just wanted business and for me to buy a new tire from them and my tires are brand new and the only day off I had is Sunday so it was tough but I took it to diagnol tires In longmont and the owner was really nice and helpful and they patched it and time has passed and tire has been running strong and I drive from longmont to denver every day and very good company and oferadable prices on tires compared to other company tire shops and they do amazing work and very helpful and owner was talking about shutting his shop down in a yr or 2 that could be the worst thing to happen too longmont you can't find a better tire shop at a good price then diagnol tires so please keep this tire shop open and with love and respect.

Very cool place to score a pair of used tires. Steve is totally cool and likes what he does.
He took his time but I enjoyed chewing the fat with everyone there. Thanks!

Steve was awesome! Super honest, knew exactly what he was doing with my tire alignment, and genuine person overall. You can tell he cares about his work—and his rescue dogs, who are the sweetest. Be nice to them if you visit!

While they didn't have the size tire that I needed, the referenced me to another shop, albeit a much farther drive, that did. I was extremely grateful for the recommendation! Everyone else was just quick to get off the phone before them, so I was very pleased that they went the extra mile to get me back on the road. Thank you!

Steve is incredible. He takes very good care of your car. Rim, tires, alignment, shocks/Struts and more. He is excellent at explaining what is going on or what needs to take place. His prices are very reasonable.
I highly recommend Diagonal Tire and Alignment.

Steve is a blessing! I was in a really bad situation and I went to big corp companies, they quoted me $3600 and Steve got it fixed for $60. I can’t thank him enough, i hope everyone who needs a service will find him!
