Generally, basic tires for cruisers have little if any technology built into them. So things like tighter thread casings and belts for flat resistance are not included due mainly to the price point and demand. Funny thing is that people want less flats, there is a demand there.
Most cruiser tires are built with a casing of around 20-25 tpi or threads per inch. Since cruisers are low pressure tire types, the need for heavier or more tpi in the casings is reduced. Also the bead is made out of steel.
Normally, wire bead tires are less precise and fit fairly loosely onto the rims. The wider the tire, the less precise it becomes since it is difficult to have a tight fit on a wide 2 or 3″ rim.
We try to choose better tire compounds for Soul Beach Cruisers. While the carcass can be basic, tread and compound can be improved easily. We run two tread types, the Duro Beach Bum style with deeper grooves and the Soul Fast which is lighter weight.
We are researching higher quality casings that reinforce the bead area so that on eBikes you have a stronger tire. The main sidewall will always be thin for ride quality. Thicker sidewalls may seem good, but on a bike the tire is the main suspension, so a flexible sidewall is important.
High quality tires are very important to bicycle performance. Even for cruisers, some tires actually make riding hard due to rolling resistance. We choose to run a 3″ tire on a 4″ rim to help with rolling resistance and overall performance.
