Tire question

devo11 · #1 10-12-2020, 04:29 AM

I’m getting mixed answers on this; winter and summer tires, is it bad for the tire to remount it seasonally on the same rim or should I be mounting on winter rims and leaving summer on its original rims? If it makes a difference I have 21” run flats

21" run flats? I am going to assume then that they are a low profile tire. If so I would recommend that you get separate winter rims and tires. Low profile tires are subject to much higher stresses when mounting and have a much higher probability of sustaining some sort of bead damage making the tire inoperable. Mount them once and carry on, don't risk having them changed over several times.

Don't know anything about run flats, but for regular tires you'll have paid enough to buy winter rims pretty quick if you are taking them to a tire shop to get switched back and forth.

This! I go through this every year with work. I pay 50-60$ twice a year to swap winter tires out to summer tires and summers to winters. At 120$ year in 2-3 years I could have paid for some cheap steel rims and avoided waiting a couple hours each year at the tire shop for them to do the swap. Work doesn’t care so I have stopped trying to fight that battle. Personally though, yes I have a second set of rims for my wife’s Jeep and my plow truck. I haven’t run winters on my new truck as I don’t drive it hardly at all in the winter since I use the plow truck to go into town etc...

The answer to your specific question is 100% no... Changing tires on rims should not ever be an issue if being done properly with the right equipment for the job my an operator who knows that they are doing and pays attention.

That said, done by the newbie with no experience on sub-par machines that are not capable of handling low-profile tires, especially run-flats, then the possibility of experiencing damage to both the tire and/or rims is very real, however that should not be the customer that bears the responsibility of repairing/replacing items from any damage sustained. A reputable shop should know what they are capable of doing properly and if they are willing to take on the work and then cause the damage, they should step up and fix it.

Sadly many won’t...

Thank you Bob. Appreciate the reply. Perhaps I’ll stop in your shop to get it done.

You're getting a GREAT deal, especially if that includes balancing.

For ease and the many other advantages I run separate summers & winters, just about everyone I know does these days with the cost and time of doing the swap over. There are some REALLY expensive tire joints out there.

Takes me 15 minutes in the driveway to swap out a set of 35's and that's with wheel spacers (twice as many lug nuts)

Run flats are tires that can support the weight of the vehicle with no air pressure for approx 100 clicks at reasonable speed just to get you to a area to safely change the tire or to a service station etc....if I was running winter tires and summer tires my winter ones would be on seperate rims...easy self switch out under an hour......
