I felt sorry that I scuttled a service of this size for them. When presented with a total bill of $30, I countered with an offer of $50 which, of course was accepted. Owning a small business myself, I know what it means to be valued by a customer. -BUT- Rather than running $50 total on the credit card machine, I get a $1.75 service charge slapped on it as well. This once again reminded me that no good deed goes unpunished. Future business of mine will be going to any of their other competitors. Upper management should reacquaint the new location's personnel with the finer points of transactional etiquette.

He greeted me with a smile, asked how my day was going, and made genuine small talk while measuring my tires and taking care of everything. He was honest and clear about how long the service would take, signed me up for text message updates, and made the entire process easy and stress-free. Overall, it was a wonderful experience -- which isn't something you always expect at a tire shop. I highly recommend this location for tires and anything tire-related for your vehicle. Great customer service makes all the difference, and Aurelius delivered. The price was on point with the competition and they had what I needed within 48 hours when I originally got my tires and today it was zero dollars to rotate and balance them because I purchased it from them. I think the service quality is amazing.

I bought a truck yesterday and a nail was found in the back passenger side tire while it was being…read moreinspected by a mechanic before I purchased it. I knew at the time of purchase that the tires were fairly worn and was told by the pre-purchase inspection tech that I "should replace them before winter" (it was early spring). There was a nearby Discount Tire so I drove by and set up an appointment for the following day. I showed up for my appointment and the tech came out and inspected the nail and measured the wear on the other tires that had no nails. The Discount Tire employee took less than 30 seconds before he told me "they couldn't plug the tire and rambled off some DOT standard". I called another shop and they said "that sounds just like Discount, if it's in the top I can repair it." The other location (Big O Tire) had knowledgeable techs, was family owned, and gave me plenty of advice and fixed the tire for free. The tech at Big O said "they won't repair your tire but they will let you drive out of there with a nail stuck in your tire... which one seems more safe?" Not to mention, if it only took 30 seconds why in the world didn't they look when I was in the day before? In comparison the employees at Discount Tire seemed like minimum wage / teenagers who know little about cars and just serve the corporate bottom line. If at all possible forget Discount Tire exists. They aren't there to serve you.

They got me right in with very little wait. Steve ground off all the rough, rusty obstructions and got my tire to seal without a leak (so far anyway).

Steve adopted his mischievous mixed golden lab dog from the Fort Morgan Humane Society. That crazy, but adorable pup is Macy. So, when the Fort Morgan Humane Society was offered a free, but not-working van to transport dogs and cats, he offered to fix the van for free. Truly amazing! There were many mechanical issues with the van and it seemed as he repaired one problem another problem would pop up since the van was a 2013 Ford that was sitting in a parking lot for several years. He fixed everything! Now the Fort Morgan Humane Society has a "new" van to transport dogs and cats to the vet or to Front Range humane societies to help them find a new home when our shelter is full. This is invaluable for us. We are a small, rural, and always poor, humane society on the Eastern Plains of Colorado. Steve, we are indebted to you! Thank you, thank you, and thank you! Woof! That means "You are Terrific" in dog language. Give Macy a hug. Sage, too. Karen Benker Board Member, Fort Morgan Humane Society

I visited the Big O Tires on S Main St in Longmont on December 16, 2025, after a frustrating…read moreexperience at the Loveland location and on the strong recommendation of my mechanic, who raved about the great team here. He was absolutely right! I've been prepping my car for winter with various maintenance tasks, including an alignment that my mechanic had done at this Longmont store. The final step was new tires ("new shoes" for the car!). Unfortunately, this location didn't have the ones I wanted in stock, but Loveland did. I purchased and had them installed there--only to discover they were mounted improperly, poorly balanced, and I received little information about the tire or wheel condition before being sent on my way. Frustrated, I called my mechanic, who immediately suggested bringing it to the Longmont store. I spoke with Tyler over the phone--he had an incredibly positive attitude and told me to come in, even as late as an hour before closing (which felt especially generous for a busy shop). There were a few initial hiccups, but the team was genuinely committed to diagnosing and resolving the issue at no charge. They rebalanced the tires, and Tyler showed me firsthand (with photos and video from the balancing machine) that my wheels required an excessive amount of weights--and even then, they were hopping due to severe bends and warping. He honestly explained the wheels were in bad shape, recommended reputable places to buy replacements, and even offered to order them for me. To make up for the earlier frustrations, he promised free installation on the new wheels. I took the car home with properly balanced tires, but the ride was still rough due to those damaged wheels. After some research, I ordered new ones online from a different site. I checked with Tyler about the brand and seller's reputation--he confirmed they were solid. Delivery was lightning-fast (arrived the next day), and I brought them in the following day. Tyler and his team knocked it out quickly: swapped the rims, installed all new hardware, balanced everything perfectly, and had me on my way. They even advised me to return for a free re-torque of the lug nuts (to ensure proper seating) and a balance check after 100 miles or so of driving--which I did, and the car drove smoother than ever. Overall, an outstanding experience at the Longmont Big O Tires on S Main St! Tyler and his crew prioritize doing the job right the first time, take full accountability if something goes wrong, and go above and beyond to make it right. I'll definitely be returning and recommending them to friends and family.
