Need new tires. Advice requested.

I don’t think there is any requirement to continue to use nitrogen even if that’s what Costco or another tire shop puts in your tires.

Before you order, check the install price at your local shop. The one time I almost went this method, the only local shop that Tire Rack dealt with was so expensive that there wasn’t any savings & it actually would take longer to get because they needed to be shipped. Local tire chain had the same tires in stock, for less.

I believe to be a “TireRack Recommended Installer” they have to offer mount and balance at TR’s price, $15/wheel IIRC. It’s possible there is another tier of retail shops that will take a TR order and mount it, but on their own terms.

I usually compare Tirerack.com and DiscountTireDirect.com, last couple time DiscountTireDirect.com was cheaper. Don’t forget to take shipping into account as well.

I was going to use, iirc, tirebuyer.com, as they were cheaper than Tire Rack (my usual go to), and they offered free delivery. As an added bonus, the installer in my area was cheaper, too. However, I ended up going to Firestone because they had some crazy sale. I got the Duelers and think they are fantastic, best tires I have ever owned. I never had much luck with Michelin. My local Costco swears that the Ecopias are the best ever.

One point is that many local tire dealers offer lifetime balancing with tire purchase for relatively low fees. Contrast this with the $10/tire or so rebalancing fee if you do it individually. So if lifetime balancing saves $40-$50 over the life of the tire instead of individual rebalancing, the cheaper initial internet price may not make up for this.
