I paid almost paid $30.00 to replace a valve stem on my Silverado truck rim and I brought it in. just the tire and rim they didn't even have to dismount it off my truck? At Pep Boys on Imperial. I paid $15.00 because I had reward card from them. I would of walked out if it where not for the discount. Does anybody know of a good tire store that would do it much cheaper? $30 bucks is just to much to replace a valve stem!
