Last year I was struggling with a tire balance issue on long tracks. I’m curious if anyone has came up with a simple at home way to balancing kart tires. I know there are kits out there that are quite expensive and seem to be just 2 leg stands with a shaft going across to slide the front hub on to balance them. I thought of this while typing… I remember about 7 years ago MG and Bridgestone had a red balance mark on the outside of the tire to line up with or across from the valve stem to get the balance close. I haven’t looked at a tire since last year, so maybe I’m missing something. What do you guys do/use or what are your thoughts?
Someone told me long time ago to look inside the tire, you will see an area where the inner carcass overlaps, try to mount the tire so that area is opposite to the valve stem. You can also balance the tire/wheel on the front spindles using stick on weights.
A tire balancer of some kind is a must! At least to have them on the money. Found everywhere from shops to eBay for $20-60 range. You can search for tire balancing beads. They work great, but hard to keep when remounting tires.
Just turn the streering wheel and lock it at zero camber. Instead of spinning the tire and wheel and waiting to see where and how it stops. Tap the top of your king pin bolt with a hammer and watch the heavy part of the wheel and tire roll to the bottom. Generally placing two smaller weights at 2 o’clock and 10 o’clock will balnace out quicker than one heavy weight at 12 o’clock.
The cord overlap (heavy area) runs across the inner part of the tire at a 45 degree angle. Put a mark on the outside of your tire where that bulge is at when it passes the center of the tires inner carcuse and then mount the valve stem ligned up oppisite to the mark.
It is also interesting to mark the tire and rim to watch for the small amount of tire rotation that accures from use and effects from mounting lubes.
