Gear ratio change with larger tires

kward · 12-19-2010, 08:26 PM

Want to put some 24" tires on my lifted cart, seems like I should change the gear ratio. Can this be done and is it a good idea?

It is hard to gear down.... but your concern is correct.... just up your power

Not sure why no one offers gear sets for the more popular lifted carts, i agree it seems like a good idea. Increasing the power seems to be the only alternative to compensate. I did change the gear ratio on my cart to compensate for the 31 inch tires, but I'm running a Volkswagen transaxle. Come to think of it, I increased the power a little too

I cant remember where I saw it, but I swear theres a place somewhere that sells higher gear ratios for a cart or carts.

One of the sponsors sell some 15:1 gears. I can't remember which one though. I am not sure how much it would help but it is better than the 12:1 stock gears.

15:1 is lower gearing than 12:1

Lower gearing will up the torque, which will turn the bigger tires with less motor strain, at the cost of top speed. If that's the goal 15:1 is the direction you want to go vs 12:1 (stock).

I have a tuff 1 with 13-1 gears in the back.I'm going to 24's just to get some speed back . That is once I start working on it.

East Coast Carts has the 15:1 gears. They are around $250. I am thinking about putting these in my cart because I am fixing to mount up some 26" tires. I may also get my motor rewound by PQ.
