Not for nothing, but the OP did say he wanted to put on larger tires. They would be pretty big.

The correct tire size (circumference) for standard 8 inch cart tires is 1440 mm. Here's a link to an owners manual for the Schwinn 12 function speedometer that's most commonly installed on carts here in The Villages.

The first page explains how to setup the tire size again after changing the battery. You can skip the part about how to calculate the correct tire size, just use 1440.

Thanks, that helps. I saw that site before but was a bit concerned because the pictures of the speedometer in the manual differ from mine. But I'm now thinking that they are all pretty much the same except for the outer case.

What kind of speedometers do you install and how much are they?
