While I love the look of old-school Carlisle studs, they are not the best for street riding. My existing studs were well worn and replacements were needed. I wanted to improve rideability and safety. Looking at what's available in 6", I thought about getting 4-ply studs. The 2-ply tires tend to grow in diameter with RPM and have a squishy feel to them. They are not real inspiring in turns. Unfortunately the asphalt tends to chew studs up pretty fast. I thought about universals as they have an old-school look but I suspected that they would suffer from rapid wear like the studs. OldMiniBikes Warehouse lists these scooter tires:

But I was concerned that they'd look small and wimpy on my bike. On Thursday my work duties brought me to Langhorne, PA which placed me three miles from OldMiniBikes Warehouse. I had to stop in there since they are the east coast mini bike mecca. As I pulled into their lot it occurred to me that they may be able to let me compare the universal tires to the scooter tires. The nice guy at the parts counter, whose name I cannot recall, brought out both for me to compare. I found the universals to have an aggressive knobby tread that would probably not be the best for street riding. Actually seeing the scooter tires in person eliminated my concerns about them looking too small on the bike. They have have a similar 3.5" wide cross-section and 12.5" diameter. I bought them on the spot. They are 4-ply and max out at 35 psi (10 more than my old studs). Now that they are installed on the bike I see that my concerns were for nought. They look great and fill out the fenders. The ride is dramatically improved. They are very firm and do not grow with rpm. Cornering is drastically improved as is overall stability. If you are considering these tire and are on the fence about pulling the trigger, go for it. You will not be dissappointed (again, these are for asphalt use). Here's two additional items you will want to know. The tires are directional and have arrows molded into the sidewalls. Mounting them correctly will let water be properly ejected when used on wet surfaces. Not sure why you'd be running a street bike in wet conditions, but these tires account for that. The other point of interest is they have the word "tubeless" molded into the side wall. While that may be just fine and dandy for one-piece rims, my bike has Azusa Astro's on it, which are two-piece. I simply re-used my existing inner tubes and the tires are fine with it.
