Aloha All,
I've had cars with both disc and spoked wheels. I bought five 15" disc wheels for a TR3 from British Motor Cars, e-mai address
bmcltd@spis.net. The wheels where promised to be round and track true and they were. A new wheel option would be the alloy wheels from Moss and other suppliers available in bolt on or knock off.
The advice to go with new spoke wheels if spoke wheels is your choice is sound in my opinnion. Used wire wheels often have all or most off the spoke nipples rusted to the wheel rim and this makes it near impossible to tune it. Painted wheels are not as pricey as chromed. On a TR3 I would go with atleast a 60 spoke wheel. I use tire tubes with the spoke wheels. You may need to get a valve stem grommet if the wheels have a large valve stem hole for the tubeless style valve stem. The grommet centers the smaller tube valve stem and keeps part of the tube popping out of the hole like a hernia. I usually fine these at off road tire shops for about a $1.
You should also consider buying some tire irons which are not that expensive. I change all my tires myself. Most tire shops have have tire changing machine designed for bolt on wheels. These machines use a lug hole to keep the wheel from turning on the machine. Since a spoke wheel doesn't have a lug hole, it uses a spoke and bends it slightly. This changes the shape of the rim. You may also need to hunt around for a tire shop that can balance wire spoke (knock-off) wheels.
When you mount the spoke wheels use a water proof grease (usually boat trailer place have this) on the hub splines. This will make changing the wheel easier in the future. You may want to use a little silicone caulk smeared liberally over the spoke heads inside the wheel center. This will keep the grease from running down your spokes. Becareful not to get this on the splines.
Although wire spoke wheels to some special care, I'm pleased with mine for daily driving. If your considering competition driving, disc wheels maybe a better choice.
Safety Fast,
Dave
