Checked the front tire of the 800 Classic (spoke wheels) the other day and saw the date stamp was from ’00. That’s right – 15 years old, and I’ve been riding on it for 5 months! The rear is ‘new’ since ’06. Yikes! So, even though they’re not very worn or dry rotted, I will need new tires SOON. Looking at shop prices, adding up the fees, I am looking at about $230 in costs in addition to the tires’ price (about $150 less if I just bring in the wheels and buy tires from them). That seems a bit ridiculous to me, so I’m thinking of doing it myself. I use a homemade jack that can lift a wheel but not high enough to remove a wheel from the fender. I feel I can invest in a $100 HF jack to lift it high enough and a $30 set of spoons to do the change. My concern is with the balancing. Read online about a way to do it by building a jig to hold the tire vertically and adding weights till no part settles to the bottom. Do I need to buy multiple lead weights to have on hand? Anything need done with the spokes? Right now she’s smooth to 90 mph and I have no need to go any faster. Also can’t believe I went 90 on such an old tire. Thanks in advance y’all.
