Originally posted by Parallax For 40+ years I've run snow tires year round. The hassle and expense of changing over twice a year just isn't worth the minimal fuel savings of road tires a few* months of the year.
For sure, though if you have the tools, it's not a long job or any expense (if they're mounted on separate rims that is...). And it's not any more costly having a second set of tyres as you need to replace them every so often anyways, so you end up extending the life by using each pair half as much.
If you're running studded tyres in the winter however means you really should change them (but that's a whole other debate - modern studless tyres are pretty impressive compared to those of not long ago).
