[QUOTE="thegerg"]Don't replace a quality tire with a crappy tire, that's dumb. Plug or replace the damaged tire and put the spare back in the trunk.rawsavon
^would NOT advise this^1. If the puncture is on the sidewall (or close to it), most every place will not fix it.
Here is the reason:
In order to fix a tire properly, you must
-dismount the tire (take it off the rim)
-clean the 'wound'/remove the item that punctured if applicable
-put some chemical compound that makes the next process easier
-grind down the area around the wound
-apply glue, let it sit for a moment
-apply a patch or a patch-plug combo depending on the size of the hole
The fact that you have to use a grinder (which resembles a dremmel tool) is the reason it can't be close to the sidewall
-you only have 2 ply protection there (2 layers). If you grind through a layer = more likely to blow out
-the rest of the tire has at least 4 layers
Some places attempt to patch without taking the tire off the rim/with no grinding
-this is the 'lazy' way that will fail eventually (they just stick a plug in the hole and hope it holds...will leak eventually
2. if the tire is ruined -b/c:
-it was on sidewall
-too big of a hole
-you drove on the tire flat
-etc
...then it will have to be replaced
3. This is where I disagree with the above
-you have a nice vehicle most likely (full size spare is rare on cars and Michelin tires)
-that Michelin is most likely a perfect match for the other tires (same tire)
-so using it is your best bet
-you then buy a cheaper tire for the spare (they move the tire on the plain spare rim to your nice rim, you put a tire of less quality on the spare)
The reason I say that is
a. ensures a matching tire on your nice rim (matching is best for ride and performance quality)
b. spares are VERY seldom used by most people
-they go bad from age for more than use...rubber has a shelf life that varies with conditions.
So you might as well use it on the ground and have something that 'will just do' in your trunk
4. HOWEVER, if your tires have some age on them/wear on them, THEN YOU NEED TO REPLACE AT LEAST 2.
-it is not a good idea to have a 'new' tire (which is what your spare is) with an old one...for drive and wear reasons
I am with Raw on this.
