One of the tires on my 2020 honda fit ex has a slight bubble like picture below (the tire in pic isn't mine but it looks similar to my tire). I have my heart set on the bridgestone weatherpeak because I have them on my toyota corolla and like them. Plus I got them at a good deal at costco (iykyk). However, costco is out on my size and don't have an estimate on when they'll be in stock though tire rack is estimating end of may/early june. So I was looking at the altimax rt45 as another possibility (not through costco unfortunately) but I am concerned about the performance in snow which doesn't seem to compare to the weather peak. I live in nyc and the honda fit never goes on the highway, its mostly to drive to and from work which is local. Honestly the honda will rarily go over 25 mph. 30. mph at the most. NYC does get snow (depending on the year) which could be light or heavy. That being said, with the small bubble on the tire sidewall should I switch these asap and is the altimax rt45 a good choice or wait for the weatherpeaks to be in stock in about a month-ish?
I would say snow is a mild concern. The toyota is the one that does the more demanding drives. Honestly rain is more of a concern but snow is kind of like a curveball in nyc. That being said, the honda is not traveling far. Its a 10 mins drive to work and to the supermarket, basically low demand drives.
I run the weatherpeaks and im in MN. Due to your time limitation (assuming you cannot put this vehicle off till they come available) id suggest looking at the others Ace had suggested, can always call around too or check online inventory. You can probably get away with regular all seasons, but if you want the best getting an all weather is the choice.
Altimax RT45/43 is the best budget tires around, however it's not a match against Bridgestone WeatherPeak. You can have a look below on RT45/43 performances
If snow is a concern, I would wait for the Weatherpeaks or look for another all-weather tire... General Altimax 365AW, Cooper Discoverer Enduramax, Falken Aklimate, or Michelin CrossClimate 2s would all be viable options... The RT45 is a great all-season (read: 3-season) tire, but it's not great in snow. A decent all-weather tire is well worth it when the snow is flying.
That said, a bubble is a ticking time bomb... it might go for a mile, 10 miles, 100 miles, or 1000 miles, maybe longer... The point it you don't know when it will blowout, but it will happen eventually.
